Top speed of my dual BL. - RC-Monster Forums

JOHNNYMAXXIMA · **Top speed of my dual BL. -** 08.30.2005, 05:14 AM

Well I attempted a top speed run on my dual brushless Maxx yesterday. I only managed to record first gear though. It was really hard to drive and hold the radar gun at the same time. I managed to get 33mph out of first gear but chickened out on second gear. It was just too hard to drive that fast and hold the radar gun at the same time. Although I'm not too sure how acurate that speed was because of the fact that of maybe I didnt get it pointed right at it? So it may be more or less, I'm not sure.

My brother is coming over today so I will see if he can help me out.

I do know one thing for sure, this thing is way too heavy at 14lbs. and is in desperate need of some LiPos. That should knock it down to somewhere in the 12lb. range and help it out a bit.
I'll keep you posted.

Yeah! get a gunmen..

It might turn out handy..

Some guy with a bad sence of humor is telling he reached 45 mph on his hvmaxx, so you have got something to crush.....

It is the power that makes it hard to drive, dual is for sick people.. Is your therapist aware of your problem..?

14 lbs is not that bad...

But my guess is that on 24 cells you should be able to reach the 53 mph without too much trouble..

Lol! My therapist. She's the one that help me build it.
45mph out of an HVmaxx?? Interesting.
I'm actually running 28 cells so if I hit 50mph, I'll be happy. Anything more than that would be great.

45mph on a HV??!! Yeah, probably the last run ever, before the motor exploded.

Glad to hear your dual truck is still going strong, Johnny. May I ask what gearing you use, and what motor?

Take care

ssshhht Sly... don't wake up Promod...

JOHNNYMAXXIMA · 08.30.2005, 01:53 PM

Hey Dafni,
I am using dual 9Ls with the 9918s and 66/20 for the gearing.

Nick · 08.30.2005, 01:54 PM

It shouldn't be any faster than a single 9L? Please explain if I'm wrong. :)

What do you mean Nick?

MetalMan · 08.30.2005, 02:10 PM

It can be faster, since each motor will have less of a load, he can gear up since the motors will not get as hot as if there were a single motor. Also, he has TWICE the available power as a single motor.

Serum · 08.30.2005, 04:16 PM

Amen.. that's why i didn't really get Nicks answer..

Twice the power doesnt mean twice the speed though.. my guess is it can be geared to the 55-60 mph.. (with the best cells available)

Nick · 08.30.2005, 06:05 PM

Oh, I see.

I was thinking that 2 motors couldn't go faster than 1 because they would still reach their limits equally.

Like the theory of dropping a weight, both the same size but 1 is slightly heavier, from a 200m drop they would go the same speed just the heavier one would reach top speed quicker.

I didn't think about heat though and gearing. Doh. :)

coolhandcountry · 08.30.2005, 06:15 PM

Think of it this way. It is like running a 9l on a 7 pound truck.

coolhandcountry · 08.30.2005, 06:32 PM

Makes me want to try a daul 7xl. 36 cells. 24 64 gearing. I think it would fly.

nbcaznmaster · 08.30.2005, 09:17 PM

thats crazy, but i woulda put like 8Ls instead cuz the e-maxx would require less torque from each motor and more high end speed. Hey! after ur done, would u mine selling me one of teh 9l and 9920? PLZZZZ?
