No havent had time to run it some more but i did do some hop ups to it added a DTX sx-200 metal gear hi torque servo for the steering and a 93003 futaba servo for the throttle. But i did notice a little flex in the servo tray when the th servo is at full throttle or brake, a radio with EPA would solve this or a aluminum servo tray but the flex does not affect operation or performance but might after few months or more use due to stress. I also installed some offset jammin truggy wheels /w duratrax low profile mt [on/ off ]road tires which are around 3/4 inch taller so the gearing shouldn't be affected that extreme & put on some shock covers[socks] Also a new heavy duty servo arm for the st servo and different turnbuckles. If i was going to order any more factory hop ups the first would be a sway bar kit maybe a aluminun servo tray and F/R aluminum suspension hinge pin mounts, allmost forgot i also installed a ofna hard anodized 053? dual chamber pipe a onboard venom temp guage,duratrax failsafe [2] fuel filters and new fuel line a radio shack 1 aa battery holder wired in series to the stock 4 aa battery holder so as i can use 5 rechagable aa batteries for rx thats it for now ill check back when i finish breakin it in or add any more hop ups
