I used the mount hole's to get center of trust line only, rite in the X of the bulkhead. I used a aftermarket mount for my Saito .80. I also installed retracts. Get out your torch if you install. A real pain to line up. And I did not use wheel cups or foam wheels.
It looks like a Great little ARF.
I should have mine ready to Fly by next weekend.
Keep us / me posted if yours flys sooner.
