46ax runs fine without remote glow inverted with an OS type F plug.

I've had two of these as well, keep your power up in loops is the only thing i noticed that I could call bad. It likes to fall out of them if you don't.

I flew both of them until they were fuel soaked chunks of balsa and ply.

Ran standard Futaba 3004 servos. didn't add any shaft angle or change the mount....used stock mount to firewall.

Used all the stock hardware that came with them, clevises, horns, etc with no problems.

didn't use flaperons of any kind. It floats surprisingly well.

Ran a 10X7 two blade prop on the 46ax. Like any other plane, plan ahead let it slow and it will float.
