Hi Jink-
Original scale wheels are 94mm and 6.1oz each with axle. The new ones with brakes are from Xicoy and they are 90mm and 8.2 oz each with axle. So I lose 4mm (not awful from a scale perspective) and gain 4.2 oz overall. I also lose about 4mm in width. Gaining the ability to stop before the plane rolls to Arizona: Priceless. Not having to hog out any of the sponson to fit the new wheels: Heaven. I can live with someone telling me my wheels look a little small.
Here is a link to the wheels: https://www.xicoy.com/catalog/produc...so0rfharqjqmq0
I had new axles machined to fit my struts. The stock axles from Xicoy were too short. I did notice that Xicoy makes a 100mm wheel with brake as well. That might be a better look for your Roban since it is a slightly bigger scale than the CGRC.
FWIW, my CG calculations were done with scales and gear extended. I am too dumb for a Vanessa rig. Point being, I may need to adjust for the extra 4 oz. in front of the CG in flight. Better than behind it for sure, but still an adjustment.
Cheers,
Dan
