I said 50mph, not 60mph.

Does other ppl 'experience' mean it's truth? Do you use eagletree to see how much power is used to GET THERE, or WHILE THERE? I'm sure these little motors pump out more than 750 watts together. I don't get what you are trying to say. Your not saying i'm lying are you.

No, i am not saying you are telling lies, i am just saying that the car must have had a calibrated speedo-meter..

i allready posted my results from my eagletree in another thread i posted in reaction to you yesterday. If you took time reading it, you would have known what the measurements where.
Not going to search for them, if you want to know, dig it up.

Yes, you are right Glass, it was with an XL3100. 12 cells brought him to 50 mph.

12 cells can do about 1200 watts, and his truck was very light. 1200 watts on a 93 percent efficient motor, that's 1116 watts. that's what is needed to get a light maxx to drive 50 mph.

Well i think it's safe to say that it's not SO much the power as it is the motor handling the load for a certain amount of time... everyday bashing. I must add, i wouldnt be able to run on grass with this, hardly gravel as the motors got too hot, too hot to touch. The dual EVX were up high and right in the path of wind, i had no body on the thing.

While we are at it, my maxx did 120 the other day! LOL

I don't doubt you for a single second newe..

Was it still in one piece when it landed fromt he 7th floor?

nbcaznmaster · 12.04.2006, 05:49 PM

HAHAHAHAHAHA! thats a easy way to get it going fast. I think i got bout 35-40 mph max. It was when i had a 9L with 16 cells. This was a while ago

What units is that figure in? MPH or KPH? :p

Nope, 120 pieces that is! LOL

Or was it 120ms to be destroyed? :017:

My Rustler went 57.5mph GPS-verified. The setup was a Feigao 540 12s, MGM Compro 12012, 4s 5400mah 8C LiPo (the pack was constantly causing the LVC to kick in). The radio range at that time was terrible, maybe 150ft. in each direction (NOT enough for a good speed run).

Maxx42 · 12.04.2006, 10:20 PM

Almost 60 with a rustler is great. I ran my T4 on 3s lipo with a lehner 3600XL geared 23/78 and was able to keep good pace with my buddy's jato 3.3. Of course I had to really feather the throttle to stop from launching my truck onto it's lid. I never got to get an official speed recorded because running that setup on 3s lipo is way too much for race conditions and my 3s packs are normally in another truck. Mike reccommended the motor to me and I have to say that it's great in the T4.

What rene is saying to you zeropointbug.
Just because a motor is rated at 700 watts or even 1000 watts.
If you gear higher. Put more of a load on motor than what they are tested at.
You will get a higher wattage.
I have had a few fast trucks. I have no idea on speed. It was fast enough for me.
I would like to go faster though to. :D

zeropointbug · 12.05.2006, 12:48 PM

That's exactly what i was trying to say, they could HANDLE the extra load. I may have been putting 1000 watts peak in it, but i know i wouldn't be getting much more power output at the shaft. 300 watts was tested on a little dyno, so thats what you are getting out the thing.

Serum · 12.05.2006, 12:56 PM

And the thing i was trying to explain that you can get 6000 watts of output power (at 94 percent efficiency. not input, but outputpower) from a 1950, which is rated for 1800 watts.
