I think it will run great.

Just starting that exact project now. Only Im using a Novak HV 7.5 instead. Got it for $65 on the novak site. With Mikes conversion kit and 3s Hyperion 6500 pack. Shooting for a sub 6lb 1/8 buggy for racing indoors this winter.

Im starting a separate thread on it now.

Cant wait to read about your build JHAUTZ

Finially ordered mine !
After I sell the messy stuff and the radio, Mikes kit will be next.

Me and a buddy are trying to decide weither to go 3s or 4s running a 1512 1800kv motor
The trucks are primarly for the track with a little bashing.
Objective is keep it light as possible hence wanting to use the 3s and MambaPro but the 25T pinion and low RPM's make me wonder if 4s would be better suited ?

Your opions please ????

I personally would go with 4s on an 1800kv motor. If motor rpms are too low, especially on sensorless, startup may be a bit rough. Of course, if using a sensored setup, this isn't a concern.

We will be running sensorless,
Thanks for solidfying my thoughts sir.

Curious about your run times whom run on 4s, what could I roughly expect with 4000mah packs ?

[Bondonutz]

I know this is a very popular combo for buggys but what about for this application ?

3s, MMPro, 2650kv

3s on the 2650 motor would be better rpm-wise IMO.

I run 4s on the Tekin 1700kv buggy motor setup and get around 25-30 minutes of runtime at a rough guess.

[bryan]

3s 2650/4s 1512 your gaining weight and losing weight somewere else.Jeff i friggin love mine with the 1512 on 4s.

I know I know, But I'm a little concerned 4s might be a bit much for the track. I'm trying to set my buddy up the with the same set up but he's not as able to control the power, he's realitively new to BL so 4s he's gonna be all over the place. He's a few weeks behind me on building his so I reckon I'm just gonna have to expeiment some, just hopeing to save myself haveing to rebuild mine 2-3times to find the perfect track combo.

Thanks for your help gentlemen

[lucias]

what bodies are you guys running on your ten t's? any after market ones fit ok?

[Bondonutz]

I have yet to have my 10T in hand but was thinking Stampede bodys might be perportionate ?
When I ordered mine this week I went ahead and picked up a clear body also, as great as the stock bodies look theres only 2 colors, kinda lame selection.

[Bondonutz]

What are the ID measurements of the RCM Ten-T battery tray ???

THANK YOU!
