A wonderful transformation, John. Lovely model.
I find WASP urethanes work slightly better than F22 rubber with magnet cars on my home track. I don’t know why, but worth a try, anyway.Just ordered another very cheap Porsche 962 and a spare bodyshell. My intention is to use the spare shell on the chassis of the complete car. The discarded (duplicate of 1 I already have) body will eventually return to the track with a second hand chassis with a few slight modifications for my grandson (stronger magnet, F22 tyres) though no idea when.
Virtually unbreakable you say? You haven't met my "leettle seester"! Muhaha! Oops. Did I say that?A couple of bog standard GP cars I race on a regular basis. Quick, well planted and great fun. Also, they're virtually unbreakable.
