No we do understand each other!!
I already had been talking to rene on email.
And he said to me the best motor on 20 cells,
will be the wander 9XL.

But i was wondering if a lehner would be the beter option
And if so wich one would be beter on max 20 cells
whit boht speed and run time?

(I just can make up my mind its driving me grazy
:C: :C: :C:)
And probably my friend rené to;)

the lehner 19 series 50 will have more power than the 9xl wander. If you got the money to spend and want the best. the lehner 1950 is in my opinion a better motor. but the motor is $225 more than the 9xl.

You mean 1950/10???
And what will be the top speed, and what wil be the run time?Would a 2250 be beter than the 1950?

So i ask again which motor will be the best choice on max 20 cells
I'am looking for boht speed and run time.

I thought the quoted kv is for both versions ,but the non high amp can be run in another configuration for lower kv.
When i ordered my 1950 i ordered the hi-amp.Was this bad?

the 9xl is a great motor
I just think the lehner is a better motor
It is like 3 times the money.
1950 10 turn should be a good motor. But i don't know what you are trying to do
I think the hi amp starts at different places
I will research some for you.

Coolhand you got a 9XL right what is the top speed on 20 cells.
And how long can you run it.

I'd say in a 10lb truck a 9XL on 20 cells would give 25minutes of runtime on gp3700's and maybe 40-45mph if geared correctly.

can't i go faster on 20 cells (whit a other motor and if so what will be the run time than??)

18cells is 25 - 30 min with gp 3700. I can not run on 20 cells for lack of esc.

You could use an 8XL with 20 cells, but it wouldn't be much faster, and the runtime wouldn;t be so good. 40-45mph is pretty fast IMO..

this i got from another thread.

http://www.rc-monster.com/forum/show...highlight=2240

Speed runs with the Lehner 2240/10 using 6s Kokams. Started out with 14/51. This gearing is used for bashing and runs stone cold. The speed was over 54 mph with temps not breaking 100. Using 16/51 gearing temps were around 125 and the best speed was 59.7 mph. The combo will run 60 mph plus easy

He said that he had a run time of 15 min,But i got a savage so??

you are talking about promods emaxx. if that is what you want then go for it. He has been running a 2240 12 t last i heard of on 10sor 8s. He is also running a center diff. a 9xl with center diff would run faster too.

I din't now a centerdiff would make a diffrence.
Than i can beter stay whit the 9XL.
because of the run time.
And it's les expensive:D

Coolhand what will be the beter controller for the 9XL on 20 cells
9920 or 12020

You said: I can not run on 20 cells for lack of esc
What do you mine by that?

A 9920 would handle it fine. I think he means that he doesn't have an ESC that can handle that many cells at the moment.
