no joke..i bought e4js..low spec plastic e4..it amazing kit..compare to my previous pro kit like msx mre or t2r..even that e4 is plastic material..it too amazing..for real..after small adjustment on rear linkage coz i need to fit it with the 30mm foam tyre and replace the linkage for toe in front and rear..equip with only 10t brushless..what can i say..that enough for me..super 5 star to team magic e4..
