They supply a foam block that holds the battery and receiver behind the fuel tank.
The back of the tank is supported by the 1st bulkhead behind the firewall. This bulkhead prevents me from sliding the battery under the tank. this would put the battery forward up to the firewall. about 3" - 3.5" forward. Not enough but it helps.

What I'm thinking of doing is cutting a hatch into the bottom of the plane just behind the firewall. the battery, wrapped in foam, below the should fit just right.
OR I could cut away the bottom part of the 1st bulkhead (which is supporting the gas tank) inside the plane and that would allow me to slide the battery forward under the tank. I would have to add a shelf to support the tank if I did it this way.

So what would be less stressful to the airframe? or does it even matter?
1. Cut a hatch under the fusalage?
2. cut out the bottom of the 1st bulkhead.

I'm glad 3.5oz isnt alot of weight to add... I've never had to add before..
would the weight difference of a .36 to the recomended .40 account for it?

I like the idea of mounting the weight to the engine mount..The engine is all the way forward so theres room..

I bought allen screws today to replace the stock philips...

The bolt holes at the trailing edge of the wing do not line up with the blind nuts in the plane. I enlarged one wing hole and got the screw to catch. The holes are VERY close to the edge of the wing. metal screws VS the nylon screws I was expecting.. I cant tell if these holes are reinforce in any way. It doesnt look very strong???
