[:@][>:][:@][&o][&o] Well now I am screwed forgive the pun for breaking off 2 of the 4 screws holding on the engine mount . The engine seemed to be pointing slightly left so I decided I would put washers behind the left side to make up for some of the torque left problem . I forgot about putting non permanent loctite on the very wimpy screws they provided to fit the blind nuts in the firewall . Those screws must be made of some of the cheapest weakest metal known to man . I applied very little force to get them loose and they broke so easily I didn’t even realize 2 were broke till I had the mount in my hand . So now I have more to worry about then a plane that doesn’t want to roll . I don’t think while increasing throttle a plane should start turning left . No other plane I have ever flown did that . Anyway I don’t mean to sound defensive I know I have sooooooo much to learn but should a plane try and turn left while throttling up ? One thing you are defiantly right about is if I would have flown fast till it quite turning left ( assuming it would eventually fly straight again ) I probably could have done a decent roll . Anyway at this time it is all academic till I figure a way to remount the engine with 2 snapped off screws . I am not a builder my planes were used and put together and the 4* was my first ARF the Twist just needed engine and radio . So like I said if I can’t get the broke screws out I am screwed since I wouldn’t know how or want to attempt cutting the firewall out and replace it .
