I'm sure it could use some down thrust, that would help with the trim change. It has enough right thrust I think, it doesn't pull to the left when going vertical. I didn't do a very good job in getting the horizonal stab level when I expoxied it in place and built some down trim into it, so that adds to the trim problem too. Its not a big problem I just need to remember to set the trim for launch. I'll try to get the next one right.
