I asked Lenore about those motors a couple of months back and she was asking $10 each for them at the time. The price might have changed since then.
This is all my fault.I saw the Russkit 22's in the BPR display case this last weekend. They were marked $25 each.
The week before the Legends race, we got all inspired here on this thread--Philippe posted his Brabham pics, Rocky started heterodyning, & I called BPR asking for these motors; forget who I talked to, but he thought they were around $10 and didn't have time to dig--could I talk to Lenore? So I called back, on race day as it turned out, & Lenore turned to Philippe who said...and now it's "official."
All my fault. I created a MARKET!! Me and my big mouse.
All that aside, any 16D--the cool thing is the limited rubber footprint providing a natural upper end to how much power you want in these cars.
