Well I have a mostly aluminum maxx, rrp steel gear kit FOC, steel cvds, and steel center shafts. I have the bulkless FLM front and rear, flm arms, flm braces, flm front and rear skid plate, flm shock mounts, big bores, trinity blue HD springs, rc solutions cage, os21tm, stock 3.3 chassis and electronics. I am upgrading to a bluebird 821 highspeed high torque steering servo and probally moving the 2055 to the throttle or getting another 821 for the throttle. I was looking for steering upgrades, I dont have knuckles yet, but not worried about that now. I have the stock 3.3 turnbuckles and keep ripping them out of the end peices. I have tried to find metal end peices for the turnbuckles to no avail. My main concern is steering. I want to upgrade the bellcranks and such. Went to my LHS and they told me the best they can get is the integy, they cannot get proline steering. Which should I get? I would imagine the integy parts would be fine for this application even though they are weak, but I have read nothing but good things about the proline steering kit. WTF should I do? As you could imagine it is heavy as all hell in comparison to a stock 3.3.
