i hear ya jetmech05. i havent been having any issue with the tower engine. being new and all to the nitro plane scene...though i do have nitro experience with my past boats and trucks.the worst that happens with a truck or boat is it just stops where it is and if a plane engine quits ....well its just a little bit tougher to deal with. i religiously maintain my engines and equipment so barring the odd flameout or glitch im not anticipating to many "problems". i flew the mkii this past sunday with success. i think the balance is still a little to the tail. but otherwise alls good. i will be 30min epoxying the wing halfs together but other than that the only other thing ive done is add a hobbico air alert lost plane finder....... i hate elm trees... blast you.that was the second "flight". if in your manual it says DO NOT DISREGARD THIS STEP believe it.
