Speaking of the 2-speed transmission, does anyone have a baseline setting on the 2 screws that adjust shift point? I have not got mine to shift at all yet. Thanks

i'm noy too sure, but a lot of people if they're having troubles will wind both screws in so they are just snug, then back them out around 1&1/2 turns as a starting point.
also with the centax clutch, how do u adjust its take up point. i assume u loosen the hex screw for earlier and tighten for later. is this correct.
cheers.

bro, its hard to notice the shifting of the car. i can hardly hear my car shifting but its does you just notice it coz theres a push. Anyway for the centax clutch im not following the manual's specs of 0.5 to 0.8mm i dont have a space for the screw thread to be seen also i added up a couple of shims.

i'm having the same problem with shifting. ive had to wind mine out pretty much as far as it will go to get it to shift. and the motor is reaching peak revs in 1st. also the rear diff has been locked with some sort of putty/clay.it seems that the clutch gets too hot and starts to slip. could the rear diff being locked cause extra stress on the clutch? is there anything i can do to stop the clutch from slipping? or is this a common problem? cheers.

I have recently started racing this car in the UK and have read this forum with interest, however I don't seem to be able to find any online set-ups for it, can you guys point me in the right direction. I have heard that there are a couple of US drivers that go very well with it and was wondering how I may contact them.

You guys are going to make me put my EBMods OS motor in. I currently run an EB Mods Novarossi NS12S3 and it runs great but as I salvate reading your post, it's making me curious. Let us know how it goes in a race.

I love this car it's tough and inexpensive to run.

i was at the track wednesday night and it kept lifting its inside left wheel during the tighter right handers. also was easy to roll. i've checked (by hand and eye)the springs, shocks, droop screws front and rear and it all seems as though the setup is consistent side to side. the only thing i havent checked is the front sway bar (gpx4) as i have no idea how to actually adjust the blade type. any help would be awesome. cheers.

Simon.

Default Sway bar!!

Simon,
I have had a look at the manual and the sway bar adjuster is a flat head screw and it is set at horizontal for standard setting if you rotate the screws either side towards the back of the car to 45 degrees this will add preload or stiffen the front but this is easy if your adjusters on the top are level and to check this you will have to take all the wheels and the front shocks off and lay the car flat on the table or setup board and add a 10mm spacer under the chassis front and rear and check either side of the front as to which side touches the ground first and adjust so they are the same its a bit like setting droop but without wheels on OK hope this helps, PM me if you have any issues.
