I always start my glow engines by flipping them the "wrong" way. I dont actualy push it all the way through the compression but just bump it off of the compression and then it will kick over and run the right way. The bigger the glo engine is the harder it is to flip start them all the way through the compression so the bigger ones are easer to bump start backwards. If your starting small engines in the normal running direction just make sure when you flip it you flip all the way through the compression and that your not just bumping off of it and it will start in the correct direction.

Also make sure you set your fail safe correctly. If you radio looses connection with the receiver you should have it set to KILL the engine. This is important trust me I learned the hardway and ruined both wings on a 25%er. When I accidently turned the radio off instead of hitting the trim dn button to kill the engine like I was trying to do it went full throttle out of control into a run up table.
