12/29/2014 - Jim H came across an interesting How-To video on YouTube by the FliteTest guys. In it they cover how to waterproof your receiver, servo’s and ESC’s. Brushless motors don’t need any special prep. They can run underwater as is.

In the beginning of the video they fly a COAX helicopter from the bottom of a fishtank full of water out of the tank and into the air.

The key tool needed is a spray can of CorrosionX. It takes almost no time at all. ESC’s are a little more effort and involve sealing the ESC with 24hr epoxy. You can use  5 to 60 minute epoxy, but it does not last as long.

If you are into flying off of water, running cars through puddles or use RC boats this video is worth a watch.



12/26/2014 - Did you get some hobby related gifts this year? Are you chomping at the bit to fly, drive, hover or build? Here are a few things to check first:

  • Save all the packing material until you know there is no damage.
  • Bind and Fly aircraft? Sometimes. Check all the controls for center and that they all work. Dont forget to remove the bind plug!
  • Always check your CG! Batteries can vary in weight quite a bit.
  • Does your new aircraft include an AS3X receiver, stabilization system or has SAFE technology? READ THE MANUAL! These systems may need special settings on your radio and before flight will usually need to run through a self calibration on a flat surface when they are powered on.
  • We all look forward to seeing new aircraft at the field, but we also hate to see a maiden flight turn out to be the only flight. So make sure to triple check your aircraft. Its a good idea to let somebody else look it over as well.
  • If you got something more advanced than you are used to flying, dont be bashful about asking somebody else to be with you on the first flight or to maiden it for you. An out of trim aircraft can be a handful!
  • Check any LiPO’s with a cell tester before the first charge. Once in a while you get a pack out of balance or with a dead cell. Always balance charge a new pack. 
  • Some people like to break-in a new LiPo by taking it easy on it from a discharge POV for the first few charges. It is reported that it increases the packs lifespan.
  • DO NOT charge LiPO batteries unattended! New or old LiPos are the same in this respect. Factory defects do occur.
  • Never assume your charger will be smart enough to see something wrong with a pack or correct a setting you programmed into it.
  • If you got a quad read the instructions first. There are usually some arming procedures for the throttle to work.
  • New power tools? Make sure you understand how to operate them safely.



12/24/2014 - We would like to wish everyone a wonderful and safe Christmas. 


12/22/2014 - The FAA released a video to educate people about safe operation of Unmanned Aircraft. The Christmas themed video aims to keep the untold number of people getting quads as gifts from promptly causing problems in the national airspace. This comes on the heels of an announcement that the FAA, AMA, Association of Unmanned Vehicle Systems International and the Small UAV Coalition have started a campaign to educate people on the regulations governing and safe operation of drones. They created a website for the campaign named Know before You Fly

The Washington Post paints a picture of confusion in the FAA with senior officials overruling some agency safety inspectors and approving commercial use of drones by some filmmakers. The number of FAA approvals for commercial use is very small compared to european countries.

Could this mean they are beginning to see the writing on the wall? Have they finally decided to accept that they are trying to put a genie back in a bottle? Time will tell.



12/20/2014 - It doesn’t take Einstein to recognize the difference in sound at CRCS the past two years. Probably 80% to 90% of the time the only sound heard aside from air whistling is the sound of electric motors whining. We’ll leave the peanut gallery's bellowing sound out of this article and focus on the sound of our planes. 

I’m not saying that a screaming 2 stroke glow or 30-60cc gasser sounds real either. Glow four strokes and twin 100cc gassers are the only thing we have flown that sounds anything like a real plane. For a while there it seemed like everybody was moving toward the quieter and better sounding 4 stroke glow engines. Suddenly glow power fell off a cliff and the electric revolution took the lead.

With the switch to electric power we lost a measure of excitement though. The sound of engines running is missing. Imagine going to a full scale auto race track where the only sound is the whine of electric motors. Its like the smell of burnt glow fuel. Not something thats particulaly good in large doses, but in moderation adds a special ambiance to the experience.

Warbird foamies are looking very realistic and are getting a little bigger every year. Most these days come with lights, retracts, flaps and miscellaneous operating goodies. They look very good until you hit the throttle. That is a real shame. 

All is not lost. How many of us used clothes pins to attach playing cards on our bicycles to use the spokes to make an engine sound when we were kids? A similar option is available for our planes. No I am not saying lets glue playing cards to our cowling! Our resident airplane hacker, Wayne Coons once brought an electric plane to a club meeting for show and tell equipped with a sound system. It was impressive and plenty loud. Those of you that were not there missed out on something very interesting.

There are sources for sound systems for electric planes available, but one big consideration and limitation for sound systems has been weight. The electronics weigh next to nothing, but to get decent sound you needed good speakers mounted in the plane. Additionally the sound is directional. If the speaker is on a side away from you the sound level is greatly reduced. You were also required to cut holes in the airframe for the sound to get out. Not very appealing and in a lot of cases not possible due to weight.

How about if I told you that you can buy a loud sound system (up to 108db!) for virtually any plane and without the weight of speakers? MrRCSound provides a system that uses transducers that  actually make the foam airframe a speaker. No need to cut holes and only one transducer is needed in most cases. Weight for the whole system is under 4oz.


You can order direct from the manufacturer MrRCSound or from one of his US dealers such as One significant consideration is price. The MrRCSound system costs $149.99 plus $13 shipping. Thats about 2/3 the price of the airplane itself in many cases. The transducer uses doublesided tape to stick to the side of the airframe, so you may need to buy a new transducer to move the system to another plane since removing the tape may damage the transducer. Still it is very appealing.


12/17/2014 - HobbyKing just released 62” (1600mm) DC-3 and C-47 PNF ARFs. They have all the goodies you have come to expect from the larger EPO foam ARF’s: Retracts, Flaps, Landing lights, Nav lights, Opening passenger door and a large hatch on the nose for battery installation. 

In addition to the two 20A ESC’s this one also has a separate BEC for powering radio, lights and gear. You will need a receiver with enough channels to control all the features and a single 3300 to 4000mAh 4S LiPo battery to get it in the air.

There is a pretty lengthy thread discussing this ARF over at RCGroups.

They are available from the East Coast US warehouse. The price is pretty fair for a large PNF twin at $308 for the C-47 and $309 for the DC-3. I guess the silver paint cost more than the olive drab. Its $40 more than the 1875mm B-17. However if you hover on the page for a while you might get it for less. While preparing this article HK offered it to me for $287. Shipping via FedEx is a tad less than $18. Since I already have a couple of 4S 4000mAh batteries, a spare 8 channel receiver and being as Christmas is next week I bought it.

Read my review of this plane. It looks nice, but has thorns.


12/16/2014 - HobbyKing posted a video on YouYube yesterday titled 'Don’t Ruin it for the rest of us'. 

The video is the start of a series teaching basic FPV flying do’s and don’ts. This first video is intended to point out that you need to be careful where you fly FPV. They keep it very basic and don’t mention altitude as a potential issue. The primary focus seems to be don’t use FPV to be a Peeping Tom in your neighborhood, don’t fly near airports, don’t fly near areas where full scale helicopters take off/land and be careful of your frequency because it might crash somebody elses FPV aircraft.

This is a great first step to educate customers. But where was the concern over a year ago when the reports of FPV started to snowball out of control? Why is one of the worlds biggest retailers of FPV gear just now taking an interest in FPV safety? 

Better late than never I guess. I would like to see all the other retailers and manufacturers of FPV gear follow this example. If not creating their own videos at least post flight safety information with the product description. 


12/15/2014 - CRCS now has a YouTube channel for videos. Weve just started, but already have over 20 videos on the channel and growing! Click the YouTube picture to be taken to the Channel. This link is also available on the Media tab.

12/14/2014 - The skies were clear and while the temperature started out near freezing it warmed up to 70 degrees both days. Winds were light and variable. Members that came out very early said it never felt very cold.

Saturday was a fly fly fly day. Lots of members and very little dead air time. Bob B and Eddie give us a formation giant scale smoke demo. Bud G remaidened his Trex 550 helicopter with a Spartan Vortex flybarless unit. Moocho better than the BeastX that had been on it. Bill E showed off his new ultra micro Quad.

Sunday everybody except Gary Q  and Dave B must have slept in, gone to church or just had a busy morning because the field was nearly empty until 11am. They started rolling in after that time though. Anna G flew more this day than she has in months. Jim H fed us crackers to keep us from flying all the time. Wayne Coons brought out a Rogallo wing micro plane he built.

No notable crashes to speak of this weekend (Jim H flew too, guess he got it out of his system). 



12/12/2014 - Corsair fans your prayers have been answered. Those of you that drooled over Lancers big Corsair last year can now get your hands on one. 

They are calling it giant scale, but at 65” its really a 60 size bird. Still it looks very nice in the pictures. It can be electric or gas powered. Retracts are optional. 

Keep an eye on the reviews when they pop up in RCG and RCU. H9 has historically put out some very nice flying sport scale warbirds and then redesigned them to appear more scale like and took the sport flyer manners out of the model.

Hangar 9 has started taking pre-orders for this beautiful F4U. The price is right at $390



12/12/2014 - E-flite has announced and HorizonHobby has started taking pre-orders for this new EDF. It has a 36 wingspan and comes with an AS3X receiver. 

On the negative side it does not have retracts. My money says that Jim H and Dave B will be buying one of these. 

It needs only a 4s 3200mAh LiPo for power and DSM/DSM2 transmitter. Retails for $300.


12/10/2014 - Drones, drones everywhere! Almost daily reports of full scale aircraft encountering drones in the area around airports! What will the FAA do to get a handle on the unregulated and out of control drone operators? They may choose to model their regulations after the rules of other countries.

In New Zealand the equivalent of the FAA is called the CAA. It is a government body that lays out the rules for all things that fly in NZ. Part of this mechanism is a partnership with the equivalent of our AMA called the MFNZ (Model Flying New Zealand). This partnership is particularly important in NZ because many model fields are either close to or share the field with full scale aircraft.

Along with government specific regulations regarding model flying and flying sites the CAA also mandates that to fly a radio controlled model legally within 2 miles (4 km) of an aerodrome in the country you must be the holder of a pilot qualification issued by a model association approved by the CAA. In this case the approved association is the MFNZ. 

What is this pilot qualification? Its a card issued to a person who has demonstrated an understanding of the rules of flight as defined by the CAA and MFNZ. The person must pass a basic flight examination. Only people that possess this card or are under the direct supervision of a person possessing this card may fly within 2 miles (4km) of an aerodrome. Its called the NZ Wings Badge.

Sounds pretty reasonable, but also means you must annually pay the MFNZ membership fee to keep yourself current if you fly close to an aerodrome. Thats the price of entry in the NZ model world and ya gotta do what ya gotta do to fly there. 

Where things get a little more complicated are when you cross paths with the MFNZ in a negative way. You can lose flying privileges at fields near an aerodrome if the MFNZ pulls your NZ Wings Badge. Generally this is a result of unsafe behavior.

One well versed New Zealand modeler who is also a prolific YouTube RC How-To and Product Reviewer indicates there are other ways to cause the MFNZ to pull your Wings Badge.  His model flying field and business are located on a full scale field so he must be an MFNZ member and have a Wings Badge in order to run his business which is the review of model products and tutorials. 

Watch the videos below. You be the judge. Did he do something wrong or was he just too vocal in his disagreement with what he calls outdated MFNZ rules? 


12/8/2014 - E-flite has issued a product recall on Super Cub S HBZ8100 and HBZ8180 products due to a fire hazard associated with the power supply and charger. Click the picture to be taken to the E-Flite recall notice website.

12/6/2014 - Saturday was a great day to fly at CRCS. Overcast, but otherwise weather was great. 70 degrees and winds were 3mph or less. 

There was a lot of flying. Bill E and Roy joined the Quad corp. They both appeared to be seeing how far the small quads could be flown across the field before loss of sight. Turns out it was just about at the edge of the runway. Jim H remaidened his P-51 after a crash Friday.

It was not an uneventful day. Eddie R broke his Apprentice into a few pieces. Bob C celebrated his birthday by making his Apprentice wing a three piece affair. The crash prize goes to Jim H for the complete obliteration of his big U Can Do 3d. The engine was buried up to the firewall in the ground. It appears he had a BEC failure shortly after take off. Straight into the ground at full throttle. The noise was like a large tree falling. 



12/5/2014 - The Post and Courier newspaper printed an editorial on the hazards of Drones. As public awareness grows more pressure will be applied to control the flying of remotely piloted aircraft. 

The question is will they see a difference between line of sight model flying done at CRCS and the FPV flying that is generating the bad press? 

Will the government recognize organized flying fields and clubs chartered by the AMA as legitimate flying sites for models or will the regulations impact all remote control flying?

Should model clubs reach out to the media to point out the differences?
