Well hearing all this, i like the fact the mugen doesnt have to change cars much to stay in competition.They must have great quality in thier products.I think im going to get a new kit soon besides the rs4 3 soon i was thinking the R40 but mugen is very appealing and im leaning towards the mtx-3. Get some experience with mugen and hpi ya know.
ive use to own a mugen mtx3 and now own the RRR. i have to say the RRR has alot more corner speed than the mugen and the RRR has alot more tuning options which can either be a good thing or the worst thing for some depending on your tuning expirience. Although i will have to give mugen the nod on build quality. for example Shocks and pinion gears. the plastic on the kyosho seems to be just as good as mugen's.
