Ok my bad. I am new to the iProperties thing.
This should have been caught by me, knowing that the CIMs together weigh about 5lbs.
There is no way that transmission weighs 9 lbs!!! More like 3.
The transmission is basically a hybrid of a WCP 2 CIM DS, 2.15lbs. and 3 CIM DS, 3.5lbs. Weight will be between that since it is basically a stretched DS if you will. A 2CIM DS with one extra idler. We went with an idler gear instead of belts. Much easier for us, we had it on hand.
The entire transmission was designed using the existing gears from our 3CIM DS making it easy to test by just replacing the frames. Future orders of different gear ratios from WCP will just work.
Last year we used the WCP 3CIM DS and are extremely happy with it. Never had any issues with breakers tripping on our 6 wheel WCD but space was tight.
We wanted a stretched 2 CIM DS, if you will. That was set up for in-frame chain setup and over the frame motor orientation. (see hex frame).
Being able to orientate the motors in either direction and a quick and easy encoder placement was the goal.
Our competition bots have always had a post tapped into the front or rear axle that the encoder used. Not always pretty..
Something different for us..
