Here's a question for you guys...
When I fly my Hellcat I have a hard time getting a straight and level track. It's very touchy on the elevator as if it is sort of porpoising a little. It's not totally out of control, just hard to keep straight and level.
I've reduced my elevator throws as much as I care to go.
According to the plans, the CG should be around 25mm. Does this sound like a tail heavy situation?

Thanks, Chris
