Lehner Basic XL 2800 on 24 volts? - Page 3 - RC-Monster Forums

extremexmods · 03.31.2006, 03:34 PM

What about a lehner 1950 6 wind sold here, on 20 cells then when I get used to the power, I could get a second controller and motor an have a total of 3600 watts. I want to step up slowly (1800, then 3600) to get used to the power.

Well by the time you buy the two controllers and motors you could have got one 2280 motor and one controller alot cheaper and it will pull alot of speed from a hi gearing. If you run 30 cells on a 2280 it should fly. If it doesn't tear the truck apart.

yeah go with a 2280 with a good controller you will be much more likely to get the speed you want with that setup.

What controller, could I use a 6 wind 2250 on a BK Electronics 12020 Warrior Controller with 20 cells? How many amps would it draw? Why are the 2250 motors rated at 2000 watts and 3000 watts? What would the perforance be with a dual lehner 3080 setup?

thats funny....dual 3080s. That truely is funny as hell. a 3080 is so big there would only be room enough for one. not to mention, you need 10mm pinions, there 700 dollars a piece, and it takes a minimum of about 24 cells to get it moving nicely. ONE 2280 with a center diff and aobut 28 or 30 cells should be plenty to beat promod. i think you should break 80 with that setup.

The drive line would never survive a dual 3060 setup. I had enough problems with one 2250.

What speed controls for dual 3080 motors? What about supermaxx parts? How fast could I go with an oversized motor mount (from my dual 970 sized motor kit) a load of lipos, and some fast gears? I want speed, but what kind of damage would a collision at top speed with this setup do?

squeeforever · 04.01.2006, 11:14 PM

did you read my post? it wouldnt be possible really. a 2280 would be more than enough to beat promod...

Well when you squee the trigger to get it to hi speed it would have shafts and gears flying out of the rc. try a dual 2280 first. I think the 36150 should handlethe power. It may even mount up to your 970 motor mount as well. I don't know if you have a brushless experence but you sure what a system that well desroy a driveline.

I've been running this setup for well over 5 years...I originally purchased this motor and controller setup...back in the day when Maximizer products was carrying BK stuff......back then I purchased a 1895 Micro controller with a 1920/8 lehner motor......I'm still running this motor today.....of which has more than enough torque and speed for me ...as for the controller...somehow last spring I managed to send 123 amps...thru the controler and fried it..according to BK....so I sent it in and they replaced it with a 2095 micro controller for about $150.00......Needless to say I was very happy...All I'm saying is while you want all this speed and torque...you might be spending alot of money and will continue to break stuff.....or your emaxx...might be so uncontrollable it isn't any fun at all......listen to some of the recomendations and pick something realitivly reasonable to what you want and have fun.....just my .02 worth....

ps...my emaxx....is geared the following..

13t pinion/66t spur
1920/8 lehner...2095 micro bec
12 cells matched in series....3300 nimh GP cells
8 spyder UE diffs
Gen II Ultramaxxed tranny gears....spare set of Gen III's if needed

If any one has any other Q's about my set up...just ask...

Can a BK 36120 Brushless Car Controller take a 2280 6 wind (1233 rpm/volt) on 16 cells, or would that pull too many amps or come to close to the 42,000 rpm limit?

MetalMan · 04.02.2006, 03:16 PM

Only 16 cells? That's only about 23,000 RPM. If you use 30 cells, then you would have a nice setup. The motor would be spinning at about 40,000 RPM max - a nice spot to have it.

extremexmods · 04.02.2006, 07:53 PM

That 16 cells was a typo. I meant 26 cells with the 6 wind (1233 rpm/volt), which would be 38,469.6 rpms. But now I am thinking 36 cells wiith an 8 wind (925 rpm/volt) which would be 39,960 rpms. Which setup would overall be better? Would the BK 36120 Brushless Car Controller handle any of these two motors. Looked at the finedesignrc.com website and saw thes motors are rated at 2500 watts and 3000 watts. How many watts would this setup really have?

squeeforever · 04.02.2006, 08:01 PM

its very capable of that but it depends on what your batteries can deliever. i think about 26 or 28 cells would be nice with the 6 wind.

What is the fastest top speed gearing I could safely use for this setup? Absolutely no lipo cells in my truck, I do not want the risk of them catching fire and destroying my truck, I can get very inexpensive and brand new GP 3300 loose cells (7 for $25 includind wiring plus 12.00 shipping, ebay seller pointingmouse) these will power the truck, nothing else. Will my setup work?
