Hey Craig, the second mustang is my friends. Just helping him get it done. I flew the my Mustang two more times last week. Two of the motor mount bolts backed out! I put lock nuts on top of the blind nuts on the top two, and one of the bottoms. This thing vibrates violently at idle... LOL Take any plane you've built and make it twice as strong. Most of the mounting plates I've put in with hysol have broken free. Arguable if you should use ZAP to glue some stuff in for vibration damping. This is one of those planes that for every few flights you have, you'll earn an hour of maintenance, gotta stay on top of it.
The mustang flies very well and I still get a huge smile on my face on flybys... the sound is so distinct. Having an electric starter is awesome as well...
Chris, stinks the mounting kit is not up to par. I had the exact same problem, but I attributed it to them sending me the wrong length motor.... It will be interesting to see how this plane does with the three cylinder.
Headed back out with it today :-)
