Hey Lazy!

I have a YS-53 4s in the front of mine. Everything else is stock. Im using the Futaba super 7 on a 4.8v pack and I have the pack just above and aft of the fuel tank. You can see it when you look into the top of the fus right in front of the wing. This setup is just short of having a touchy elevator.
I've already snapped a motor mount and had to fabricate a new one. So be on the lookout for cracks.

Good Luck,
DD
