Finally got some good weather to run and taxi the jet, I checked for hit build up and I did feel anything much getting warm at all. The outer wall of both sides I was worried since the motors angle out and hit that area even that are didnt get to warm. Outside of the thrust vector didnt get hot once activated so that was nice, im sure over time it will change colors but with airflow inflight I think it will stay well below temps that can cause paint bubble. Steering is super sensitive it will literally turn on dime, so that will need to a lot of EXPO. Next step is to fly it, just not sure when or where that will be. Cheers
