YR4 SP custom 2 speed

YR4 好多人版本
我出 YR4 SP custom

原裝尾 pulley can rub the motor mount, no good, slim down motor mount much better l. Also level out rear upper link. Original slanted, no good

First on original. Last one photo faster steering.

暫時放住 ONEWAY + slipper pulley

No la. Cut down original

Great machining on motor mount.

May I ask which chassis is your SP Custom? As 2~3 chassis photos posted on this thread. Thanks a lot.

One more question, is the belts length changed? Thanks again.

Same belt. The car was a YR4 Sp= First generation YR4 with graphite chassis

This YR4 custom is using a self-designed chassis. The concept is to max out the mod in material & geometry base on what I think is the best. Ti screws too

2 speed added 不過仲未得住

This 2 speed was designed with a ‘catcher’, on-off system, not smooth on shifting from 1 to 2 gear, chew up the spur gear 磨薑

Machined it down, 改輕

Done. Used OFNA 1/10 parts

Part list from another bro on RCTECH

I did not make a new clutch bell, just trimmed down the Yokomo original clutch bell ;)

又改多少少
