I am going to the track tomorrow..12:41am...okay today, i will try to get some video of it. Although, that center diff is way to loose with 100k oil in it. I have some 500k on order should be here tuesday or so and I will post some videos then.

Oh I should add, temps are about 5-15 degrees over ambient for the ESC and about 120-140 on the motor running in ~60 degrees indoor after a 20 min run.

looks good. whered you get the black feigao?

All the Feigao XL motors come in black now as far as I know.

Great looking truck!! I would think that 6s would be a little much for the 9xl.... have fun at the track!! :smile:

cool.... the purple looked like crap.

I thought Mike has them in black now too.

That's one heck of a ride! a 9XL on 6S! that will be a peppy beast. I guess you can start to stock up drivetrain parts! you will be about the fastest on the track, i would keep an eye on the temps of that motor/speedo.

Looks good. Check that clutch bell/spur alignment. In the pictures it looks like there is a little misalignment. Could cause wear or stripping problems.

I'm interested to hear how you like the Tekno clutch setup and I'm looking forward to seeing the vid.

Nice clean job.

Well ran at the track today, friend forgot the video camera. Had a bad day today, basically comes down to a co-worker broke my battery and I am using a make shift battery for the time being.

The motor temp got a little high today. Hit about 160, I was beating on it pretty hard. I will definitly be putting a fan on the motor.

In the picture nothing was setup, just thrown together.

Your 9xl was 160 on a 6s?

On the heatsink yea.

How are the battery and esc temps? I read somewhere (see BrianG's sig) that if your batteries and esc are cool but motor is hot, then its likely your undergeard... do you have any bigger CB's to try?

or maybe his clutch is slipping and causing the same effect.

i didn't see a pixtix or what ever its called. do you not need it for that controller?

Just realised your only running a 9XL, which means at 22.2v your revving it out past 40,000rpm! From what I've read this is revving too hard for a feigao motor - and could very well be the source of your overheating.

On another note, how is that ESC? Looking at the programming card available it only has "low" "middle" and "high" voltage cutoff points, do you know how many lipo cells these cut off points correspond to? I would hate to ruin a 6s pack by over discharging it, and this esc (which I was looking at buying) doesn't seem to have very useful lipo cutoff programming...

I am almost done with my Revo 3.3 and Spektrum 3.0 with a Tekno conversion and throttle linkage, JR 9100T Steering Servo, Hitec HS5645 brake servo RPM arms and knuckles. I also have the Sentilion OEMRC ESC, a 6s 3700 25C Lipo pack, also from United Hobbies. I'm using an Align 600 motor. As of now I haven't tried anything yet, but it's nice to read about someone using most of the same stuff running around happily. Please post a vid when you have a chance. I figured I may as well get all my HV stuff (batteries/lipo charger) and what I hope will work (cheap ESC) to use until the MMM is released.

The batt temp is low. I don't consider 160 degrees really THAT hot, throw on a fan it'll be fine. Once I get my center some thicker oil so I can get some traction I'll play around with the gearing. I highly doubt the clutch is slipping considering it's new, backwards, and has no spring.

pixtix?

You only would run past 40k rpm if your wide open, which is rare. Honestly if I break a $60 motor that just gives me a good excuse to get a Neu!

That ESC runs cool which I like, it has probably the worst programming/instructions I have ever seen. I tried to get one of those programming cards when I ordered it but it was out of stock. The cut-off low/medium/high refers to cut off being 2.6v/2.85v/3.1v times the amount of cells you have which it calculates for you. Default is medium which is 17.1v which is a little low for the recommended manufacturer cut-off of 3v (18v) per cell. Regardless you can tell when the lipo is dying. As soon as I notice this I quit. After a full run I'll throw about 4500mah back into the pack with about 20v before charge.

Awesome, looks like that will be my new esc :) if it breaks, hopefully the MM will be out by then

Those programming cards are in stock now I just ordered one.

I have the programming card as well, but have yet to try it out. As you already know..

{{The instructions associated with the ESC do seem a little vague, but the ones for the programming card a better. Apparently the ESC comes set to the "medium" cut-off setting which is 2.85v/cell. You can change this with the programming card to 3.1v/cell.}}

I will definitely set the ESC to 3.1v/cell setting for LVC. If they don't come in stock at United, send me a PM and I'll let you borrow the one I have.

I got one of the last ones from this round :P Will have my esc and board soon. plus a heap of wire and connectors woot!

What motor are you getting? Getting the teckno conversion?

Feigao 11XL with RCM motor mount. Running 6s. I also found some ceramic bearings for the feigao motors which are rated to 70,000rpm - I wouldnt push em that hard but it could maybe help with the temps at high rpm.

Just a little thing I did today. Doesn't show much but was fun!

haha very cool, I've never seen so much ICE!! that must be cool living right next to a frozen lake... here I am in 35C (= 95F) I wonder how much my motor will heat up :lol: What was the temp of the motor like after that run? I imagine there was a bit of high revving on the ice.

Also, do you have footage of any top speed runs? I'd like to see how quick this thing will go :)

This is with the center diff ungodly loose.

haha nice. So how hot does the esc get with a lot of low throttle driving? like around a tight track or just if you dont want it jacking up the on back wheels and loosing control all the time :P

It doesn't get hot at all. It got about 85 in 65 degree weather. This is what I measured after a 15 min run at the track. This track is pretty small and has tight turns.

looks good. i'm asking so many questions about the esc, because i've been planning on getting one for my next conversion. the pistic i was asking about earlier is to allow use of an air esc with a pistal radio. are you using a pistal radio with your setup? does it drive normal?

In one of the customer feedback reviews on hobbycity it says:
I know its not proof that it's fine, but it was good enough for me, plus I dont think Routybouty is using a stick radio or a pistix, so should be fine.

Never heard of that. What is it, some type of device between the esc and rx? I'm running a Spektrum DX3R and it works like normal. I just had a heck of a time programming it, but I'm gonna blame that on the instructions.

Yea I read all the reviews on it from hobbycity and everyone stated it was a good esc, that was the deciding factor in me getting one.

what fluid are you running in your CD?

500k now.

when you filmed the video?

Only the one on the ice, the other video was with 100k, which is why you can hear the front tires spinning.

looks like the rear arms would hit the motor. does it?

Yea it does. But only at the very top of the travel. I put a tiny notch in the arm and it doesn't really hit now. Kinda bums me out because I sent an e-mail to here and asked if it would hit with my motor, conversion kit, and the heat-sink and I was told it wouldn't.

Flip the front motor plate over, and it will sit slightly higher, allowing the motor to clear the arms. By the pics on the first page you have it attached so that the motor sits lower. Tekno did this on purpose so that longer motors could clear the arms, or shorter motors could be mounted lower to drop the cg a bit.

i hope RC monster's mount does not do that.

RCM mount doesn't - I run it with an XL. It doesn't need all that extra room for the clutch setup etc.

And Tekno even say in their write up of the conversion that you can use the XL motor, so maybe you do have it mounted in the Low CG position as lincpimp says? Then again when they say it works with the XL motor, they don't mention using the RCM heatsink with it too which could add a few mm to it.

hey i was thinking of picking up this esc and motor combo for my e-revo as it is cheaper than the mamba..i have 14 cells right now thne later to a nice 5s lipo. but is this reliable and easy enough to use? i am also getting the programing card as well would that be a good idea too? thanks alot and sweet revo

The programming card is a good idea, makes programming a breeze. I like the combo in my truck, the esc hasnt got a built in BEC though so be sure to factor in that as an additional cost (I'd recommend the cc bec, coz i like castle lol :P).

Be aware though, that you do get what you pay for. This ESC is not without flaw. It's enormous for one, the heatsink interface is very poor by the looks of it (havent pulled it apart yet, but it looks like it has a thick layer of crappy double sided thermal tape as an interface), and the start up is a bit funny. It doesn't cog, but it's almost as if it has a lot of 'puch control' (if your familiar with the CC programming options), even when normal start is selected (as opposed to soft or super soft). Instead of cogging it just is an ultra smooth power transition, no instant 'punch' that you might expect. If you get the tekno conversion it might not be such an issue since you have a nitro clutch.

no i have an erevo with a emaxx tranny but i think that would help with breaking parts though.
