Yes Ill probably getting a foam RTF before flying these balsa wood ones, I dont want to wreck them out of the gate and I want to learn much more about the engines. I called the place in California to get heli coil replaced on the FA-91 and it was only $35.00. Great deal. The guy at hobby shop told me to toss the engine because it will cost more than its worth and give me too much trouble. Ill risk the $35.00 vs $325.00 for a new one. I also need a new Throttle Barrel Assembly because the linkage clip is missing the little snap ring that holds it in place. So assuming the inside of the engine is in decent shape, it just might be salvageable.
I found out that different glow plugs have different threads...
so yeah didnt know that, so that confirmes that I put the wrong type in there and cross threaded it
Good times
