no iv got a tower st-15 i also fly rc planes i brought my st-15 out there one day and another guy had a evader we raced well mostly justed played around his beat me by about 5mph then the only upgrade i had in it then was bearings over bushings in the wheels i had six left in my duratrax bearing set since then i found out i had to replace bushings with bearings in tranny i rekked it before i replaced the bushings plastik shocks stripped and broke suspension arm came lose lost a dogbone ordered new dogbone set and aluminum shocks on the official st-15 thread joelacrane pionered in replacing the short stock suspension arms with rc10gt arms they just bolt right on but frost is still working on some driveshafts the stock ones are too short for the rc10 arms but i ordered some rc10 arms anyway ill just hold them of till we can figure out some kind of drive system but since the last time i ran it replaced bearings in tranny and added tuned pipe it comes stock with a crap muffler it should be able to keep up with a evader now.
