Thanks for all the tips guys. I ended up cutting off the original mounting screw heads and replaced the gear with a Fults. I used a long piece of threaded rod to start the blind nuts in the firewall. I had to really think about how I was going to get those blind nuts in place. Made my brain hurt a bit. I also went with a 3" wheel instead of the 2.75 original size. I started using a 12 x 6 prop instead of the 3 blade after the first training session. That shortened up the take-off run a bit. All is well now, I hope. Now the weather is calling for thunder storms on my training night. (solo night) That just prolongs the butterflies I have to endure untill I finally solo. [X(]
