I've been running a Novak Fusion/Demon quad wind (forget what turn?) in my 2wd Meteor without any problems! (kiss of death) And have a minty Tekin 700 Pro Pulse residing in a pan car, which has had a few different motors thrown at it without fault. I'd say if your going racing? Stick with modern electrics. Will be better in the long run! Bashing/shelfers, go with the vintage
