As far as making stiffer arms... I am all for it. There must be some reason the companies who are very sucessful on foam tires such as xray and corally have all come out with extra hard arms that the foam tire guys use .. Why would corally and xray waste time , effort and money in designing and testing something that "ISNT NEEDED". I know i am not an engineer, but many many racers who have looked over and checked out my car have all said the same things.. those arms need to be stiffer. The soft arms that come with the FT TC5 is part of why the TC5 is amazing on rubber tires. ( also why xray came out with softer arms for the rubber tire cars )
Dont get me wrong this car is very good but it is just a few $$ Hop Up $$ parts away from being incredible.. Hop Up parts are also a nice way for associated to cash in . Especially when there are tons of people hoping and wishing for them.
