I dont want to give any specifics on that but i can assure you that it is a great starting point.

Is there a particular servo that people prefer fit-wise in the CH12? I looked through the thread for pics and had a hard time identifying most as the pictures are from above. It looks to me as though the chassis is drilled to accept KO, Futaba, and JR servos all on the passenger side, correct?

I've used the Futaba 9650 and the KO PDS-951ICS and I like both of them. I think I have a slight preference for the KO though...it just seems a little bit faster and fits with no issues.

Cheers,
Mike

the chassis is slotted, so most any mini will work. in the past futaba has been reccomended (9650, 9602) and recently the jr 3650 has been suggested.

the jr servo body is shallow compared to the futaba, so if you like to run the servo in the laid down position, then the jr wire fouls the servo post.

Tony,

If you like to use the 3650 in the laid down position, just cut the servo mount. I got a spare set of BMI servo mounts and cut off the angled portion with a dremel, leaving only the "L". Flat mounting works fine with no interference.

to be honest, the only time i tried it,(with a 9650) i never got the bump steer and ackerman quite right, and have never tried again.

i agree that if i was commited to one layout or the other it wouldn't hurt quite so much to hack off the unused part.

Quick question for Jason and anyone else that wants to chime in ...

Starting from the setup that Jason posted a few pages back, what changes would you make to run on a track that has pretty high traction but is REALLY bumpy. I mean the car was catching air off of one of the bumps if I didn't pick exactly the right line down the straight and there were a few bumps that threw the car completely off line entering a few corners .

Any and all suggestions would be appreciated!

Cheers,
Mike

I'm using the DES 676 BB from Graupner. Great servo!!! Cheap as hell and the performance is superb!

Soften the car up all the way around, ie...more front AND rear pod droop. Possibly 35-40 wt oil w/Assoc.blue (CRC red) center spring.

Yeah, soften the car up and go with more droop front and rear. Try going to 2mm pod droop and 1-1.5mm front droop. Allowing some uptravel help keep the tires on the ground and the softer spring rate will help absorb the shock from the bumps. Also try a little softer front dampening in the tube.

hi Jason,

can you clarify the part #'s for the pivot ball assemblies?

CH3029 is listed as the 'single mount pivot ball housing'. i presume this is the new style housing but with one fastener hole for the new front end outer pivot.

i think DB3029 is the multiple piece pivot ball from the db12.

so what is the part number for the '2 point mount pivot ball' that replaces DB3029?
