I have been busy working on the challenger the last few weeks, but bad about posting!
I have the steel "scale like" mount finished up, and is a complete module; engine, ignition, exhaust system and mounts, throttle and choke servos and excess oil catch, are all mounted on the tubular mount. So, my plan is to glass bead and then etch prime and paint the mount. Then put everything together for final assembly. Finally, bolt the whole assembly to the test stand and run it. This way I can set everything up as a unit on the test stand.
