lehner 2250 13turn

[extremexmods]

Do not see why the GP 4300 is bad while the GP 3300 is better. How are IB batteries better than Gold Peak? What are the voltages of the GP 4300 and the IB 4200, when they are zapped and matched? I guess I will have to get the IB cells, but then I lose 100 mah worth of runtime? H

Runtime? I thought this was a speed run machine? 5 mins should be enough.

[Sneeck]

I begin to wonder how big of a wooden board you got stuck before your head. How many freagin' time's do I have to tell you that it's

NOT

about voltage, but amperage. For example, if you got 1.20 volt cell's they may aswell give that voltage at only 20 amp's discharge. While other cell's give out 1.175 volt's on 30 amp's discharge, and so on. Voltage doesn't mean the cell is good for your setup and what your going to do with it. If it was a 1/10 onroad racer, you want the most voltage as possible since voltage mean's more rpm, and amp's mean torque aka power. In your case you need amp's to let a 13 turn motor put out enough torque to get it to speed, plus push around a heavy monstertruck with 2 kg's of battery's alone.

The gp3300 are hand's down the BEST cell's as to discharge amp's. Good quality gp's can put out over 100 amp's! at their peak's without failing. Try doing that to unmatched cell's...

And like Gustav said, forget about runtime on your setup. It will be a power rush of 10 minute's top's. It's not a every-day bashing setup you choose to run. It's a uncontrolable speed machine which better has a wide open field to run in.

Extrememods;

We are willing to help you, but you ask questions, you get answers and you don't believe the answers.

I don't want to be rude in what way ever, but looking at the questions you ask, you don't have got experience; example; the q's about drivetrain, batteries etc. that is nothing to worry about though, that's what this forum is for. You ask what you don't know and you get answers. If this answer is not in line of your expectation, why are we the first you doubt, instead of yourself?

Here is the part that bugs me most; Why be stubborn about something you don't even know? and you state it like 'i don't see why the 4300's would not be as good as the 3300's'

Don't ignore our posts, read them careful and do something with that information. We help you, but at this point i feel like talking onto a wall.

Please don't take this wrong, again, i have got no cruel intentions to wards you, i just say what's in my mind.

I wish you nothing but the best with your speed project, but take notice that this ain't an every day ride. And again, Promod got to that point on own power, he just tried every setup possible. Why is your goal to beat him?

If it's pure to show off, i will stop posting in this thread.

Promod is a great guy, he has got a HUGE knowledge when it comes to brushless powersetups. And all and all, he is humble and keen.

[Gustav]

I don't know how anyone else feels but i really wasn't bothered about who had the speed record when Promod was doing it,didn't see like a competative thing,more just he was passionate about BL and wanted to show what it could do and go real fast.

Extremexmods,I don't mean to be rude but i've sensed a slightly impertinent attitude at times despite the fact that you wish to use other's knowledge(not least what Promod showed us) to claim '1st place' as you put it.Something about 'standing on the shoulders of giants' (Isaac Newton)springs to mind.Maybe i've misunderstood.
Are you sure you want to spend your money on breaking the record when someone could just whip out a credit card and take it right back?:028:

EDIT;oops cross post,i was carefully wording this for a while,didn't see Serums post.Basically what he said.

i agree with serum.

promod was very humble and loved to experiment with different motors and setups. He had a wealth of nowledge and used it to get him that speed record. he also never cut any corners when building his many projects. promods knowledge of bl setups was far superior to most people but he still kept his humbleness.i can only wish that i will have half the knowledge he has.

[coolhandcountry]

Oh by the way. If you look up promods truck on here it does not have all the stock stuff no more. He went with a center diff.

I have decided I do not need the extreme power of a 2250 on 36 cells. I have decided on a 2230 on 20 cells. I also can't afford it without receiving a whole load of :035: :031: :035: :031: :035: :031: :035: :031: :007: :007:. Should I use a 10 turn (1972 rpm per volt) or a 11 turn (1793 rpm per volt)? Can I use a BK electronics Warrior 9920 on this motor or should I use a Warrior 12020?

Those look like a good deal. However 150$ is alot of money to spend on something with no return policy.

Those are "buget cells". Check out common sense RC for a good line of budget cells.

You can get a (2) 3100 4s batteries at 6200 mah for roughly 135$ from there.

[coolhandcountry]

I would go 11 turn and the 9920 should handle it. may consider a 12 turn as well.

[extremexmods]

If the Warrior 9920 can take a 2230 11 turn on 20 cells, could the Warrior 12020 take a 2240 8 turn (1850 rpm/volt) on 20 cells?

[squeeforever]

It should.

[extremexmods]

Here is where the power setup will be used. Have confirmed by measuring this motor will fit if I move the speed control and receiver to the top plate. The car is very durable and handles great, but for a 1/10th scale is very heavy.

The car is much heavier than the car in this article which broke 111 mph and has four wheel drive, the current record holder did not.
http://www.rccaraction.com/articles/need_speed.asp
I think I may have read this article too many times for my own good, but speed records do not last as good, I think the car is better for a speed record than an emaxx. I confess, I am addicted to speed.
I think the final setup will be this car powered by a Warrior 12020, lehner 2240 8 turn (hope the controller doesnt blow up:013: :026: ), 20 matched GP 3300 cells. Overall reaction will be:004: :004: :004: :004: :004: :027: :027: :005:. I hope the rc gods are looking at me in my favor. Any suggestions on gearing will be needed.

[squeeforever]

I don't think a 2240 will even fit be able to fit in that car. Plus you would have to make a motor mount, and that won't be to easy for a tc.

[extremexmods]

It will work, and it will be fast.:027:
How many watts is the 2240 8 turn on 20 cells? Is it enough for a speed record if I can mount the motor?
