I have an H9 Edge in my shop waiting for me to finish a Topflite Gold Edition P-47, so I appreciate the experience/advice in this posting. I plan to install a G-38 with elevator and rudder servos in the tail. Any experience out there with the G-38 in this plane?

I agree with beefing firewalls and landing gear. I lost a Big Stik to gear failure. I installed aluminum gear, which pulled the bottom out after a series of loops, ejecting the battery with predictable results.
