RE: Predator II setup
Rudder -Not typo. It's a Vtail. You need to select V tail on your computer radio. Take offs without rudder are possible but can get ugly with these things. Upright mounting of the engine will be a problem because the carb will be to high above the tank. Mount it sideways. You got a plastic mount because you got an old model Pred, not a Pred 2. You only need dual rates if you are going to pylon race.
