Sorry I have been a little busy the last few months. My mother in-law past away and that took me out of it for a awhile. I am back at it now and I hope to have the wing done this weekend. Here is a few pics of the RCGF 56 mounted to a great planes anti-vibration mount. The manual of the RTC kit says the distance from the firewall to the prop hub is 7.5" to 7 3/4". The RCGF 56 was 6.5" right out of the box so I used the Great Planes anti-vibration mount to get another inch
. Here is how it worked out.
I think it came out just about right
