HELP Installing Receiver
 

OK I tried once but maybe put it in the wrong category. On a plane with limited radio compartment room, I don't have enough room to wrap the receiver with foam. Has anyone ever mounted the receiver and battery with silicone? Anyone have any other ideas

Thanks,
Bob

If it's to big why not try a smaller rx? The foam helps keep the vibration from shaking the rx and I don't think silicone would do that as well. Maybe I'm wrong...

rx mounting
 

I sometimes cut a piece of 1/4"foam that is the size of the bottom of the rx. Place the piece of foam against the bottom of the fuse. Set the rx on top of the foam, and cut another piece of foam to go over the top of the rx. The I place a 1/4 by 1/4 balsa stick across the fuse against the top piece of foam, slightly compressing it. Thin CA to hold the balsa stick in place. It has to be snug enough that it won't come loose of course. This will only work if you can run the rx longways with the fuse, so the balsa stick doesn't go across the plug in area. The sides of the rx doesn't have to have foam covering them, but at the same time, the sides can't be touching anything. I do most of my rx this way. They never come loose.

How about some double-sided foam tape? I often use it to hold the receiver in place, especially when installing in hard to reach places. The receiver floats on the foam, and I believe this is a very vibration resistant method. It is a good idea to first wrap the receiver with a piece of good clear tape, in a bad crash the receiver is going to want to fly and it will be in pieces with the base still stuck to the remains of the plane. The clear tape also makes it easier to remove the foam tape from the receiver for remounting.

If there is space on the top/sides of the receiver you can stick on some single sided foam tape too, this will help to protect it if it does go its own way. I have found some stuff for car stereo installations that is about 3/4 wide x 3/16 inch thick, comes in rolls and works well, good protection in a small package.

I sometimes also supplement this method with what Sunray is talking about, using foam with a couple sticks to double anchor everything, especially on a low wing plane when the receiver will be "hanging" continuously from the foam tape.

Mounts
 

Try "hook&loop" or better known as Velcro. Takes up very little space and absorbs vibration.
Before sticking down the half that will stay in the plane, first coat the wood with CA and lightly sand to give the adhesive a better grip.

I,am with Carlos on the velcro. In pylon racing room is at a premium even with mini Rx's and Velcro is commonly used. More than enought vibration isolation but of course not much crash protection. If you use this method do not rely on the stickum, The hooks are appied to the Rx bottom with Ca. and the loops to the airframe with Ca.

I've used velcro on some of my profiles and combat planes,works but have lost two recievers in crashes. Foam or the plastic with air bubbles is the better protection.

Thanks for the ideas, I didn't know we could get 1/4" foam. That might just work.
The Velcro and double-sided foam tape are good ideas too, I might use that on my 1/2A plane.
:D

I use velcro attached to the plane and the reciever with epoxy
glue. sand the bottom of the receiver first and then glue. Also
attach batt. pak with RTV gasket silicon. I do this in all planes now
fun fly to 30% gas powered.

Everybody---I read in one of the modeling magazines some time ago that the ONLY foam insulation is foam rubber. The article sead
that polystyrene, polyureathane, and any other type of foam will
vibrate at the same frequency (?) as the source. Foam rubber is the only type to use. The others will certainly help when gravity is
turned on all the way, but not while every thing is in one piece.
I know at least HiTec even gives you a little foam rubber blanket for the receiver. I don't recall if the article mentioned velcro or silicone. It was in either Model Airplane News or RCM.

Just my $0.03 worth.

Take a look at the Hitec 555 and SlimLine receivers.

On my little planes I often use the 1/8" thick foam cushion shoe insoles which are available in drug stores and supermarkets. One side is foam and the other is cloth. Saves a lot of space.
