motoring on

After finding the ff050 motors encroaching on cockpit space I fitted a Solarbotics 030 motor and immediately acheived a better space for a driver.


Chris W suggested the Mitsumi 030 motors so I bought some at huge expense(not)
I have a car partly built where I will try the Mitsumi motor but you can see a little work is needed before doing so.

Has any body used the Mitsumi? The Solarbotic motor I do have some experience with.

I have experience with the solarbotics and have never found a way to overcome the lack of torque....
Large crowns would possibly work but not in the cars I build!

Although not easy to find, there are some 80DP crowns and pinions that will allow short (er) gearing - 4:1 or higher - in tight spaces.

I tried a couple of Mitsumi and found they were only around 13,000RPM , What do yours rev at?
The Solarbotics at least rev around 22,000 so can be geared around 3:1 for some reliability.

Thanks Phil...I havent put one on my tach yet but was being lazy and asking for others thoughts.
The Solarbotics motors are a fun motor. I havent had one pop or let the smoke out yet.

Some figures are available here....

Thanks Peter, I will have to test one in a car now.
After Phil k's info I think I will use a 9 or maybe 10 tooth pinion and go from there.
