I'm working on getting another one of my late Dad's old balsa planes flight worthy and noticed that the right aileron has a millimeter or two of upwards deflection at the wing tip. These are full span ailerons on a low wing nitro sport plane so I'd like to get everything as true as I can before I take it out for a maiden flight.

My current plan is to use a combination of gentle clamping and some pins to push the Ail a millimeter or so in the opposite direction to the current warp, give it some time to settle and then work the clamps back until it stays straight. Alternatively, I can just build a new aileron but I'm avoiding that because of the hinges are epoxied into a pocket in the center of the wing and aileron.

I fly with ELRS and am trying to avoid using a gyro so that I can use flaperons instead of having to install split flaps or air brakes. That said, I am doing everything I can to keep myself from crashing a balsa plane so I might just swallow my pride and use a spektrum rx with AS3X just for extra stability (but not until I get it trimmed out).

The Manufacturer recommended solution for battery retention on the crack yak is friction [and prayers], which is definitively inadequate. The other day the battery came flying off and away during a roll and I was only able to find it because there happened to be a guy that owned a metal detector also flying planes at the park.

My solution is simple enough that IMO it should be included with the base kit or at least a recommendation in the instructions. Velcro/hook & loop in the designated spot then you just need a card of any kind (mayhaps your ama membership?) to use as a slide for inserting or removing the battery.

Also the crack is my favorite plane in my fleet.
