Plenty of other manufacturers have copied Xray's winning designs in the past... its common practice in all forms of racing... even F1 teams spy on the other cars on the grid to try and replicate successful designs to improve performance!
The Yokomo is a feckin fast car so if thats what the XB2 'resembles' it can only be a good thing. The difference will be that the Yokomo cars are cheap and brittle and the Xray is quality and extremely strong.
I'd take a good car built well over a good car built badly, any day of the week!
