brushless losi 8ight truggy

[nitroman26]

I have a spankin new losi 8ight t RTR and a brushless conversion kit. I'm just unsure of what brushless systen to put in this beast I really want it to rip. (Heck I put a 3.3 nitro in crt.5 1/12 scale.) I heard good and bad on all systems. but more info the better.
thanks

If you want overkill run a Neu 1515 1y or 2d motor, Mamba Monster Max ESC, and a high quality 4-5S lipo pack with at least 6000mah capacity and 20C cont. discharge rate.

I've talked to a few others that have had issues with the mamba monster max? Are the novak hv systems any good?

The Novak Systems are Great, get this one http://www.teamnovak.com/products/brushless/hv_pro_systems/index.html the 4.5 will give you the most power and speed with a good 4 cell lipo battery..

thats actually the one I was looking at, but I heard that it might run to hot in a truggy. so I thought I would get another opinion
thanks

The first batch of MMM had issues that are supposed to be corrected with the current batch. I wouldn't even worry much abut it, Castle CS is second to none.

Have you ever run a 4.5 on a 4S? It's a 5,000Kv motor, and would not last long at the 70,000+ rpm it would turn.

I figured with all the improvments that have been made like
HV BRUSHLESS MOTORS WITH 5MM SHAFTS
In addition to its already impressive features, including awesome starting torque, low-speed driveability, and no cogging for smooth acceleration and smooth braking, the HV Series of motors (#3524-3527) has been fitted with a rugged 5mm output shaft for maximum resilience and race life. The HV Series is ideal for monster trucks, converted electric 1/8-scale vehicles and vehicles requiring massive power output. Additionally, the motors are sensor-based, so they always know the position of the rotor, which provides excellent starting torque and continuous synchronization for smooth, controlled low-speed driveability and consistent brakes. Simply stated, it means no uncontrolled bursts of power or delays! HV-Series of motors also features a shielded sensor cable with sheathed sensor wires and a completely rebuildable design.
and the fact that it is rated for up to 14 cells nimh or 4s lipo it should hold up fine, I have there older 6.5 version in my E Maxx and run it on 2 7cell nimh packs with out any problems, but I could be wrong, it was just a suggestion...

The ESC is rated for up to 4S, not the motor. Also, the motor that you have (6.5) is a much lower Kv rating, turning over 15,000 less rpms on 4S.

Increasing the shaft size to 5mm does not increase the maximum rpms of the motor, but does make the motor more suitable for applications which require the use of a mod 1 pinion gear.

I just figured the motor would be able to handle a 4s lipo because it would not make since to sale a motor that can not handle that kind power with a ESC that can, they will be doing a lot of warranty work if that is the case.

You are absolutely correct in stating the 4.5 will work with 4S. Novak has a disclaimer on their web page stating it should be used for "short high speed runs only". It also states that the largest pinion should be used. This is peculiar because normally when you run a higher rpm motor you run a smaller pinion to lessen the load on the motor and ESC.

I can only speculate that Novak knows that running the largest pinion on a high rpm motor will never allow the motor to rev to it's maximum potential unless a very very large area is used. I still have strong reservations against running a 5,000Kv motor on 4S as it will not be durable or stable.

Then again, it only has to last 1 day longer than the 120 day warranty, right? :\

I would wait for the mamba monster system that is coming out in mid october for around $300 and it suppose to be an exact copy of the neu motors. If you can't wait then get mamba monster esc and a neu motor. I had the novak hv pro system 6.5 and it broke it twice in 2 months so they replaced the whole system for new after $65 except the lipo cut off and it is now for sale.
