Re: VEXPro 2014 Product Initial Impressions

Did something change with the VersaPlanetaries or were they always so easy to mate together with a BAG motor? We assembled them with RS-775 & RS-550 motors last year and still had some minor binding after several attempts from 4 different individuals. Both VersaPlanetaries went together very smoothly this year on the first try with BAG motors.

The new bearing gussets are very nice. The 'end' gusset is very easy to bend at the same point with imprecise equipment, allowing us to add a long roller intake on top of a plate.

We were happy to find the 7:1 VP ratio. It matched our intake roller speed to our drive train speed very nicely.

One product I'd like to see in the future is a 1/2" hex-hex shaft coupler. We're getting away with a beefy 3D printed Nylon coupler on a low-torque application for now, but an Aluminum coupler with built-in shaft collars would be nice for high-powered applications. The printed coupler went through many iterations for tolerance, strength & brittleness before the final iteration, which works like a champ.

On another note, I'm surprised the teams surrounding the IFI warehouse aren't screaming 'free USPS shipping on a single low-value item if you send us team t-shirts or 3D print us something'. I wanted to order a 10:1 gear kit by itself and the shipping was more than the part. It wasn't a huge deal - we tacked it onto a larger order a week later, but it also meant we got our production ratios a week later than desired.
