Bruno,

I did put some extra epoxy on the trays as well. I had to put an ext on the elev and rudder servo, the wire for the throttle was long enough for the rcv to sit up front over the wing.

I have a friend who has a ME and he has a Magnum .52 on it and had to put a half stick on the engine mount to balance at 3.5. But he didn't put his battery in the tank compartment like I did. I split the stick and put it in with the tank as well to get the lateral balance right. It worked out to about 1/3 on oneside for the lateral. I stood them vert in the tank compart at the rear, the battery is all the way fwd.

I'm still hoping to fly this weekend, I'll let ya know how it goes.
