Bearing question. Just get a wooden dowel approx. the same size and tap slightly. Thats what most people use to get out there bearing out of the bulkheads.

Only use the locked front diff for smooth, flowing tracks (like the asphault Ripon track or the Tamiya USA track.) It will feel like a one-way but you can actually brake like a diff (according to Jimmy Jacobsen.) I haven't tried it myself yet.

Since the diff is locked, something has to give in a crash. Delrin outdrives and aluminum dogbones (driveshafts) will break very easily! So use the steel units.

out of the box, the whole diff units have some side-to-side play. also, the diff pulleys seem to wobble a bit on the outdrives. i guess this is normal because it doesnt cause any problems. im running stock, but i dont know if the play becomes severe when using mod.

Just to clarify the confusion on the roll centers. The more you raise the suspension blocks, the more you raise the roll center. The reason to do this is to prevent the car from having as much chassis roll, while running softer springs. This doesn't raise or lower the center of gravity on the car, it just changes the axis on which the suspension will pivot. Having a higher roll center creates less leverage on the suspension arms- giving it a "stiffer" side- to- side feel.

The reason to run the high roll centers on the 414 is to take away chassis roll. The chassis on this car is very stiff (it doesn't flex like other cars), therefore the suspension does all the work (instead of the chassis "giving" a little). High roll centers are very beneficial in tight, technical tracks and allow the car to transition smoother from side to side and corner better.

On the locked front diff, try running it with a center one way pulley. Works incredible and makes the car super easy to drive on high speed, "flowing" (big radius and sweeping corners) tracks. I ran it with much succes for about 2 months until they layed out a new, tighter, more technical track.

Actually in Surikarn's setup you do lower CG as you also raise the camber point on the bulkhead, but you still change the roll-centre as you use less spacers under the camber links then under the suspension blocks....

CristianTabush, got a question for you. I run on a tight technical track (carpet with foams) and I am trying to get the car to flow better through the corners. I have raised the roll center in the car to take out some of the chassis roll (trying to keep the car flat in the corner) but now I find that the inside rear wheel lifts in the corners, do you have any idea what could be the reason and or how to fix it.

thanks..............

hm ...... tried stiffening the front end ????
try this first - the most practical way ...


then to analyse ...
reason ... i am not too sure ... but ... my guess is that front roll centre is too low?? or maybe too high ??

did u raise the front suspension mounts as well ??

whats ur full settings now ??


-----
hehe actually i am trying to get my car setup for fun to do stunts ...2 wheel conering
i can actually do that with my old car but not this one ... have not found the exact fine point for it yet
hehe playing around with it will help me learn the car better

and .. btw ... just to add on some theory stuff here ...
hm .. theres a rule saying that the car will NOT LEAN/ROLL or SLIDE if the roll centre is ABOVE the centre of gravity of the car .....

why..... i have no idea ...its just something i read b4 somewhere ...
