Stu, Wood is stronger than you think...
The whole weapon pod is VERY strong, and has a foot area (in contact with the base) of 60cm2, this is connected to the base via 8 6mm screws. When you come to RC Wars (might not run the disc unless he gets a net or something) I will show you its true strength. Oh, and thats a 12v motor run @ 24v e.g. Ive got LOADS of speed and LOADS of torque from that weapon motor...
Cheers, Ewan
