1/8 brushless conversion

[Rcrcrus]

Hi i have finnely seen the bright side and joind oople after 2 years!!

I've always run 1/10 electric and now changed to 1/8 nitro truggy Lot more fun). But the nitro is doing my head in. I'm running a losi 8t. I'm read all the forums i can find and i've enden up where i started. :confused:

I've looked at the losi and novak conversion kit and gone for losi as lay out looks a lot better.
Lipos i hope to use demon pack as they are good packs and cheap. Used them before in 1/10.
As for motor and speedo, hell nows where to start.
The m-troniks looks good but the motor shaft dia is not 5mm. Good point it's waterproof.
I have always used novak and trusted in them. but it is not cheap.
And then everybody seems to be talking about hobbywings. Which speedo 80A or 150A and what kv/turn motor will best suit a truggy. Nice and cheap. In a truggy it's not really water tight.

I'm sure there must be someone or someone's out there to send me in a better direction.:thumbsup:

Welcome to the Forums!

Q+A
I've looked at the losi and novak conversion kit and gone for losi as lay out looks a lot better.
1. I agree, the Losi kit is waaaaaay better than the Novak one.
Lipos i hope to use demon pack as they are good packs and cheap. Used them before in 1/10.
2. I've had no experience with these packs, but I would say provided they are 25C continuous or better, and you have a decent capacity (like 5000mAh) they should be fine. Note you will need to run at least two of them in series to get at least 14.8V.
As for motor and speedo, hell nows where to start.
3. I would recommend the Castle Creations Monster Mamba Max ESC and Motor Combo (I would go with the 2200kV Combo for a truggy. You can get this from Horizon UK). If you go for the HobbyWing, then you will also need a motor.
The m-troniks looks good but the motor shaft dia is not 5mm. Good point it's waterproof.
4. I wouldn't bother with the MTroniks, the ESC's current rating is only about 80A continuous, and about 100A Burst, chances are, your set-up will peak at over 150A. Though waterproof IS nice!
I have always used novak and trusted in them. but it is not cheap.

5. For the price of the Novak I would go with a Castle Combo, or a 150A HobbyWing with a Medusa Research Motor (like I have - they really are very good). They will be better suited to the truggy role. The Novak motors are too high kV really to be race-suitable, and the ESC is not rated to the same Voltage as the others, which offer you more set-up flexibility.
And then everybody seems to be talking about hobbywings. Which speedo 80A or 150A and what kv/turn motor will best suit a truggy. Nice and cheap. In a truggy it's not really water tight.
6. 150A definately. I would say about 1800 - 2200kV would be about right for a truggy, you do need motor length as well though! (70mm is desirable).

To work out the set-up the best site ever is this one: http://www.scriptasylum.com/rc_speed/_top_speed.html
Just experiment with different set-ups, and aim for a 40mph top speed.

As far as where to get motors, ESC's etc, look no further than here:

They also have very informative forums too.

Hope this has helped.

:)If your interested I've just posted an MGM ESC and Neu brushless motor for sale which have come out of my Losi 8T. They only had about 6 runs as I've moved over to RC heli's.:)

Hi,

I was wondering about the LOSI brushless conversion for a 8ight 2.0 T and I have at least 2 concerns :

1° 2100kv with 4S is perfect for the buggy. What would you recommand for the Truggy. Is 2400kv enough (knowing nitro engines for Truggies are roughly 20% more powerfull)?

2° what about the body shell ? It looks like LOSI provides a body with a bloody hole for the engine. Any suggestion ? (not sure the Jconcept body shell would fit with the electric motor).

Thank you for your comments.

You want to run a lower kV in a truggy, and gear up, as the lower kV motors are more torquey, which is needed in a truggy. Something like a 1900 or 1700kV would be good. It is a common misconception that high kV=more powerful, but it is simply that they have more revs than torque. In a truggy, you need more torque, so go for lower kV. It's better to run a truggy on 5S too, for the efficiency gains. If you do, go for a 1700kV motor.

The bodies will fit, the electrics don't really stick up any more than the nitro radio box.
