RE: NitroModel Low-Wing Trainer 60 - 71
I had a ASP 61 on the nose. I mounted it as far forward as I could. I put the battery under the fuel tank and got it balance right on the spar.
I too had to redo the main gear mounts and replace the nose wheel with a Dubro one.
I have a second one I built with (2) aileron servos, plus it is electric powered. She does fly really well.
