R21 Solo

The R21 Solo equipped with the right powerplant can achieve 500 BHP per tonne and can accelerate to 100 kph (60 MPH) in well under 4 seconds, with speeds approaching 200 kph (125 MPH)!

The main structure of the Solo is constructed from 1.25″ DOM tube providing an ultralight and strong chassis. Double A-arm front and rear suspension with air shocks all-round will smooth the roughest trails and soak up the biggest landings.

These kits are like a precision steel jig-saw!
