It was the O.S. Speed 12TZ Spec 2 . It's a $440 engine though.

new question- If money is not an object, What is the best engine on the market? Highest rpm's? most power?

ehroof

werks, rb, collari, picco, os

hibityhupla

Which one has the highest rpm's? In the end if everyone had the same gearing and power that's what it would come down to.

ehroof

for the 1/8 or 1/10, .21 and larger or .18 and smaller?

hibityhupla

doesn't really matter to me. I'll make it fit. lol. But let's go with .18 or lower. Carb doesn't matter since i have a top plate for both set-ups.

thought this thread for the redcat tornado but just got my tornado running again and if i give it to much throttle it dies also it keps idling high

ehroof

ok, here you go, my pics for money is no object:

max power .12 turbo maxs 3mf
novarossi: NOVAROSSI 353 .12 or Nova.12 N12LL5
rex: REX.12 RER12S3
rb concept: RB V12 R3 IFMAR 2007
os: SPEED 12 TZ FACTORY TUNED ENGINE 3 PORT
all high reving .12, race legal

Sounds like your running a little lean. My car was doing the same thing. Mine was out about 1/2 turn but bo 1/8-1/4 at a time.

hibityhupla

do not bo, sorry.

ehroof

richen your low needle and high needle 1/2 turn each, if the needles are too lean they will sometimes idle high and die under throttle from lack of fuel. you may just need to lower the idle, just turn the screw under the air filter with the spring on it counter clockwise to lower it but it still sounds like the high needle is too lean since it dies if you give too much throttle.

ok thanks i've adjusted the idle screw before but i think i need to tune itfor sure its still at factory settings and it just got cold here

Ehroof I got 1 more for you. I just ordered a hpi r40. I've seen a few pictures and all I really know is I'll need to build it. I guess it comes with no radio or engine. Any thought's on what will be a direct fit?

ehroof

any radio system but for that car get a good one and any .18 or smaller will fit.

hibityhupla

Any clues where i would be able to find the mario rossi tuned .12 ninja with the magnesium head? The guys on the smartech page turned me on to it but I can't seem to find it for sale anywhere. Maybe it's not out yet?

ehroof

email dennis at clermontmotorsports.com , thats an expensive engine brother

AllAboutFunHobbies

Ya that's a really expensive Engine, My hobby depot might have it in stock. You can get the same or better performance from the STS 12 modded by R&Bmods for a WHOLE lot less.

ehroof

lol, never bro, never, i am sorry but there is no comparison, i know a few guys who run that engine at the track and no sts will touch that no matter who mods it.

hibityhupla

I figured it was expensive. I just can't seem to find one for sale. I'll try to email clermontmotorsports and see if I can at least get a price. The whole reason I bought the r40 is to take my time and build it the way I want. Besides that I have all winter to build it before I can do anything with it.

Has anyone had a problem with breaking clutch pads off at the pins? What would cause it? Any easy fixes besides the obvious alloy upgrade?

ehroof

upgrade the flywheel. what are you ripping the pins off of? what car?

Chubbysdad

My Feedback: (1)

check to see if your pins are not bent on the flywheel. I have seen that before. will cause alot of binding.

hibityhupla

I'm ripping apart the clutch pads. It's happened to me three times all on different cars. bb pro with 18cv-rx, smartech car pictured earlier and most recently my jato. When the clutch went in my jato it ruined the transmission either right before or right after but when I took the tranny apart everything looked and moved fine but the car won't move. ???????? I'll have to look at the pins.

Chubbysdad

My Feedback: (1)

also, I am sure its obvious, check the clutchbell bearings. Bad bearings can be a killer.

hibityhupla

I was actually just looking at some bearings. I heard boca-sp? and acer make good ceramic bearings but I'm not sure how many and what size. I'll have to look through my books again. Hard to believe those bearing kits are worth around $100.

ehroof

dennis sells the boca bearings i think, he just got a big order of them in.

hibityhupla

Who is Dennis?

What's a really good 2ch radio system? The best one i found was- SPEKTRUM DX2 DSM 2CH Pistol,1-Z270,1-Z590M SX . Actually I don't know if it's the best, just most expensive at $170.
