Another Brushless Revo Project

I got the 2.5 rolling chassis today along with some RPM upgrades....RCMonster motor clamp 3.3 trans case.....rear break kit...tekno brushless conversion.....mamba bec

Still waiting on;
feigao 7xl and a 9xl

I got the white so I can die them another color....

I did that on my 3.3 and die'd all the arms....bumpers....wing...and rims red.
I will post a pic later.

Im not sure the white would look good for too long.

hi
yes you're right. in the long run those white parts may get ugly....however that happens with other colors as well at least to some extent.
red is cool also. red/black is nice for a car.

I did a little more work tonight. I tore down the roller chassis a little more to get it nice and clean. I got the feigao 7xl in the mail today so I decided to
do a little mock up with the motor and tekno conversion hardware. It was pretty easy and I can wait to finish and get this thing on the road.

I just realized i ordered the wrong size heatsink and clamp from RCMonster......o well...I hope I can exchange it.
The only issue is needing to dremel a flat spot on the on the motor shaft for the elektri-clutch adapter.......no problem there.

So far so good.....just waiting on a few more parts and the lipo battery. Im going to use a hitec hs-645 high torque servo.
Im most likely going to get it going before installing the center dif and forward only......just to see the difference.
Also not sure what im going to do for gearing.....any suggestions?

I do have a few questions.

1. The wires on the MM esc.....red...white...black. The wires on the 7xl Red...Green...Yellow. What goes to What??
2. The Tekno instructions suggest installing the clutch shoe's in the leading position. Anyone have an issue with this?

[kingiggy262]

The colors on the motor wires don't matter just plug them in and see if it runs correctly and if not then unplug and switch two of the wires and it should work. This caused no harm when I did this to my MM setup so you should be fine.

Mine ended up being:
MM->Feigao
RED->YELLOW
WHITE->GREEN
BLACK->RED

As others have said, wire order doesn't matter for sensorless motors. Switch any two wires to reverse direction. Sensor[i]less[\i] motors are different and NEED to be hooked up in the right order.

The clutch shoes in the leading position will grab harder and slip less once they engage.

i realize that the the clutch will grab harder in the leading position but was not sure it would lead to problems...stress on gears...stuff like that. I have read that some don't use a clutch spring. I guess I will try different set ups and see what works for me.

[BrianG]

Well, seeing as how the stock tranny has a slipper, that should help cushion the blow and protect the gears. Not using a clutch spring basically makes it so the clutch engages as soon as there is pretty much any motor turning.

Well.....i guess im gonna need to find a wheelie bar them lol

It looks like im going to need to extend the esc/motor wires to bring them together. What gauge wire should i use?

[BrianG]

Whatever gauge is one the ESC. IIRC, the MM uses 13GA wire. If you are extending them, use 12GA if you can, but I heard that Castle uses solder that is difficult to work with. Just make sure you don't heat things up so much that the traces start lifting and/or burning out components.

with my Revo I have done the FOC and the CD as you have but also it really helps to do the Mod that involves removing the 1st gear and locking in the 2nd gear (with as much instant torque you get with a BL motor 1st gear is unneeded), I have read that you should use 500k fluid in the CD ( it come with 100k) but I have yet to test this for myself and also I am a basher not a racer so it is to be seen if it matters.


here is the link for the Mod

http://rc-monster.com/forum/showthread.php?t=7441

and I went with the 3rd option and using motor braking, I was thinking since I am not racing the braking won't be a major issue

AZJC......I have looked at the "2nd gear only" mod. I think im gonna leave the trans stock at first...then do the FOC and center diff.....then maybe lock out first...then close gear ratio....

I will do one mod at a time and see how it effects the truck

Im still not sure what clutch bell/slipper combo to go with.

nice one!!! another revo nearlly done!!!
