I have a Fly BMW M3 (E30 model) with, I believe, the same layout as the Capri.  The magnet has been removed ,rear tyres replaced and front tyres have been varnished. It handles quite well sometimes but the handling is inconsistent due to occasional rubbing of the front tyres on the body. This is due to the slop caused by those front stub axles. I've tried to firm up these a bit but haven't been successful so far. Of course the ideal solution would be to replace the stub axles with a solid axle but this isn't possible due to the motor location. Looking forward to hearing the results of Top Down's hypo cement fix.
By the way, the Fly Racing Capri which comes with the same looking body but which has a lightweight lexan interior, is an excellent runner. This is also inline but has a long can (instead of the FC130 motor), mounted in the traditional position.
