If it is not strong enough, I will A)Put a flange on the plate B)increase the thickness to .125" C)Do Both.

971's 2014 Gearbox:

With 8 motors I am trying to get more acceleration (mainly), and more pushing power. Spectrum ran 8 this year and really liked it so I figured I would give it a try. If it doesn't work out I will go with 3 CIM

I have seen the Spartan's transmissions up close, and definitely understnad their reasoning behind them and the proof that they work. 971 holds a high standard to their machines, and they ensure everything is well supported and correctly loaded on their transmissions. Whenever I see a transmission that looks like it could be completely bent in one hit and I don't know who made it, I try not to assume what the poster knows in the event they need some help. Of course I'm not doubting your knowledge of thin sheet transmissions (and I apologize if it came off that way), I was just being cautious and thought it would be better to give the warning and have you already know it than to not give you the warning and have you not know it.

That being said, as others have mentioned, adding flanges and/or increasing the thickness to 1/8 will make a world of difference. It looks like a design with a lot of potential, and I look forward to seeing future iterations.
