What motor took a .542 piston?

Quote

Post by mAdMan » Mon Nov 09, 2015 12:38 pm

I have 2 new pistons and sleeves that I thought were for .12 CV-Rs based on their porting. I tore down a .12 cv-r yesterday and the piston is .551. So then what do these belong to? Is it possible a Picco 12 speed has this piston size?

Found it.

The OS 12-TG
http://manuals.hobbico.com/osm/12tg-series-manual.pdf

Bore .543
Stroke .551

It's basically a stroker .12cv

I'm currently working on and testing homemade teflon piston shocks for the rere schumacher mk1 shock, and for the pro shocks.

A 2 holes version for high grip tracks, and a 3 holes version for loose conditions or bumpy tracks.

More to come soon.

Do you still make these?

I’ve been trying to get my hands on a set of 2 hole pistons for my Pro Cat Classic, but Muzzoom models have no stock… been that way for 6 months, like everything else on there!

I have been researching 10mm shock design for a build I am doing and I ran across a chart from petitrc.com that compares some of the common pistons for 10mm across brands.

Enjoy

Hey guys,

I'm looking to get a brushless motor setup, I'd like to have a decent amount of power, but nothing to overwhelm my car (stealth transmission gold pan, with B4 slipper assembly). I've picked out a few parts that would seem to work...

Thanks for you input guys...

I'm trying to figure out a motor combo to run in a Clodbuster at next year's vintage nationals. All the classes require 27T motors. I don't know of any adjustable timing or zero degree 27T motors. I was thinking of trying a pair of Sport Tuned...

I asked him and he just said that he wired one for reverse rotation and didn't do anything about the timing.

Thanks for the tip Temple, I gotta keep an eye out for those motors.

Good day,

As per title,

9000kv motor on 2S vs 4500kv motor on 4S?

Why would / could one choose one over the other?
Im I correct in understanding that the rpm output would be the same?
Difference in torque maybe?
One is cheaper than the other?...

Last post

My understanding was that efficiency is better with higher voltage battery and lower KV motor given an otherwise equal theoretical performance , I'm sure that's how it was explained to me , something like higher voltage = lower amperage and lower...
