Need info for 80mph brushless truggy... - Page 3 - RC-Monster Forums

Over_revO · 05.31.2009, 07:52 PM

I like overpowered truck, its not to show off, really.... :)

I respect that you think its useless, but i will not invest in brushless (batteries, charger, esc, motor etc..) if i cant do anything better than my nitro.

I could run my nitro revo at 66 all day long with wheelies, no overheating.

Thats why i want a good step higher. 70 isnt fast for me.
A good setup with a truggy will handle good at 70.

Can a Neu 1515 1y with the MMM on 6S handle 65mph all day with bashing without overheating?

That would really be the minimum requirement for me...

I'd go atleast a 1521 because that speed you want is geared pretty high.

Did you gps or radar your revo? 66mph all day long would take a serious nitro motor, and usually at those speeds second gear melts. That's with an o.s. .28, so you must have had some serious motor.

Usually brushless rigs are geared for one thing. Bashing, racing, or speed runs. I suggest carrying two pinions and gearing up for speed runs and gearing down for bashing. Not doing that is why your buddy is overheating.

Yes i radared it, with 2 different radar, i had a pretty high gearing, the engine was a Picco .28 modified by ABmods, drag mod....

It produce more power than a stock OS28. But i also have modified OS 28.

For sure i could not hold it at 66mph for an entire tank lol it would overheat, but i could do what i am looking for in the brushless, its just i want a brushless that can do better

thats why i targeted 80, i can live with 70, may be 65, but 60mph is not worthing it for me , we had a truggy geared for 55mph and it was pulling wheelies with a modified OS28.

I just thought you could have a wider range of power with the brushless, seeing how strong the Neu 1515 1.5d was in my friend's revo even geared for 65-70, it could flip from a standing still, but overheated....

Thats what i cant get over, a nitro will just ,not pull it and then overheat, the electric will pull it and overheat... :)

Like i said i always like to get more power than i need, its my fun.

Thx for all the tips, i will think about it and may still go brushless.

you can do it. 1521, hv110, pistix and 12s. The only thing is the cc hv110 has no brakes and makes mechanical brakes necessary. An MGM has brakes.

You friends revo was just pushing the limits geared that high.

A 1521 will handle what you want no problem, for extra insurance step up to a 1527.

Your english is fine! You speak much better than many stupid americans.

Thx man! appreciated!

Absolutely no offense to you, this is just my opinion.....

COMPLETELY USELESS, RETARDED, BORING, AND EXPENSIVE

again, just my opinion.

and ya, your lower speed drive ability is going to be in the toilet; you would need large battery for sure.

Over_revO · 06.01.2009, 06:02 AM

What some of you may dont understand is, i posted here to know if its possible, if it will overheat or not, its not like im trying to tell you its possible, im here to know if it is, so telling me you would not like the setup ....is useless...

If you guys think it would not work, and overheat, i will not do it, simple as that...

I tried a couple speeds runs with my CRT truggy yesterday. 6s 2200 geared 25/48 with buggy ratio diffs, taped holeshots tires. The best I got was 59.6mph without the front in flying high. Its hard to keep those front wheels down.

Good luck man! Make sure you get some video!

Going fast is fun. Us bashers need challenges, cause we do not have that "better driver" to beat on the track. I personally think a MM/2200 combo has enough ass to do 80, but maybe only a pass or 2 before the current draw will start causing problems. A 1527 will be the best bet, on 10-12s. That will stay cool, but you will need some good lipos to get the job done. Battery weight will be an issue, maybe something like the new thunderpower 40c packs, they are lower mah, but can handle high current demands.

I plan to do a stupid powerful 2 speed on road car myself. 1521 1y on 6s , geared to the moon, with 9000 30c worth of lipo. I have a feeling the fan on the MMM will stay on for a while...!!!
