thanks, so now the mission isxto find the right sized nuts, and washers i guess...i ordered the motor in april, im still waiting for one of my hk orders...the support guy 'accidently' cancelled it and i had to resubmit...it finally shiped 2 months later! Im still waiting for it to arrive. I like the josh and josh videos, and i have built their nutbal, funbat, and f22, now i want to build a full 4 channel dr1. Here you can get foamboard without the paper, much like depron i think, but it only cost about 2.5 per big sheet. It will be lighter, but maybe not as strong.
