I have a little question

On the SB5 do you guys reduce the maximum steering angle mechanical on the bike or just on the transmitter? I dont use very much steering on the bike so the dual rate is very low that is why i am asking

I use both ways.

Edi's "Triple Clamp One Piece" reduces the mechanical angle, and I use dual-rate to suit the track and my driving style.
Reducing it mechanically also helps a little if you have lots of headshake.
A balanced front wheel is a must, too

Okay I didnt know that. But the Measurements still apply also with this fork.
By the way looking at the picture I think you will get trouble some time once you increase the leaning angle of the bike. The screws seem to protude far out and will get hooked up with the curbs sooner or later.

SB5 carpet

Moved other post here for comments or suggestions.
Sb5 my own (lonely) dots day

--------------------------------------------------------------------------------

Starting to get a handle on doping the PMT 200's on carpet. Trying to find the best technique of when to apply, and how long to let the tire compound set before running. The best working stuff so far is the Corally "Jack The Gripper" but it's real slippery for a full 4 or 5 minutes and getting better as you run, then holds consistantly (nowhere near as well as clean black top) for 15 minutes, then lets go almost instantly and I have to stop running for lack of traction. . Any suggestions on where to buy foam donuts so I can mount and grind my own tires? Here's some of the middle good minutes.

You can have my stock SB5 tyres for free, just pay the shipping from OZ if you like... Can't see it being more the $10.00...
Would be good to see if you can get them working...

Hi, Sorry to butt in, I'm new to 2 wheel RC, I bought a kit of SB5 by Thunder Tiger, I think I set it wrong because it won't run straight, it keeps slamming on its side, I use mamba 5700 KV motor and SC10 Esc. I put a low profile servo, the tires glued on rear wheels any suggestion for setting up right?

If it will stay going straight without turning it, its probably the servo speed from right to left being different. If it just keeps leaning with out you touching the radio it may be trimmed wrong or the rear belt tensioner could be different from right to left, making the rear wheel not striaght to the chassis.

Or you need to turn down your steering dual-rate.

Or you need to revert the streering i.e. turn right on TX turns frontwheel left thereby shifting wheight of the bike to the right forcing it to want to turn that way!

Yeah Lukey, it would be nice to get them working somehow. I'm trying to get them to work on carpet and so far the stockers work better than the PMT 200's on it. I've used a couple of different tire traction compounds on the 200s with one of them working much better than the other. So far with the stockers: right out of the bag they hooked up pretty fair with no compound at all, and a little better with the same compound as the one that worked best on the 200s. then I roughed up the stockers with 150 grit sanding cloth to "break them in" and MUCH better traction showed up! since then I carved "V" shaped traction grooves in the tires in the rear with a dremel with a cutoff wheel and a simple linear groove around the front tire about 3 or 4 mm's from each outside edge
and picked up some more. During these last steps I began using Simple Green detergent to wash the tires before each run, and to my amazement, I can run the bike a solid 15 minutes without the tires giving up. Granted , it's not like on clean asphalt, but in my opinion they are raceable right now on carpet!
The reason I wanted more stock tires is so I can experiment with different tire traction compounds and traction groove shapes, just to see what works best.

Thanks so much for your offer to send your stock tires! But it's too much hassle for you to package and ship them just to save me a buck or two! I can have my local hobby shop order them with his regular order for me. Plus maybe you can cut some grooves in them and let us know how they work on a real track! Thanks again, Dave

On the topic of tires, I found this on the German RC-Motorradforum.de:

http://www.clark-s.de/artikel/pmt/65...heck_bike.html

A VERY interesting idea and very comforting for guys like me, that cant glue a front tire ever correctly!!!!! Yes, I'm about to order a couple, very soon!!!
