FWIW, I was planning to get the 1940 when I was doing by Hyper 8 buggy, but they were out of stock at the time. If they are available in the store, get it now before they sell out again!

My wife would call you satan. :005: JK - not a bad idea. I know what happens to those Lehner motors when they go out of stock. Nothing.

Well, I guess no time like the present.:dft009:

Any reason to go Hi-Amp? I've asked that a few times and gotten mixed answers.

BrianG · 03.05.2007, 09:52 PM

lol. Tell her I'm sorry. But this IS R/C after all! :) When my wife gives me grief, I just say "Would you rather me go the to bars doing God-knows-what, or be interested in something harmless like my R/C toys?". And you can always tell the missus that this purchase can be your early b-day or Christmas present. :)

The hi-amp simply has direct connections from the coils to the output wires so has less losses. However, the non-hiamp version does give you the flexibility to reconfigure the motor from D to Y for different kv ratings. I guess it depends if you'd rather have minimum resistance loss or more flexibility...

Oh, and the hi-amp doesn't necessarily mean it will pull more amps, it just means it can handle higher current since there is less resistance due to the coil configuration feature.

Oh, Ok. So does the KV rating go up or down when you change the wires?

BrianG · 03.05.2007, 09:59 PM

I believe it comes wired in D config. So wiring it in Y config decreases the kv by a factor of 1.73 IIRC. This would of course mean you can run higher voltage for the same total rpm.

Awesome. Thanks for all the info. Time to go to the "store". :027:

Yep.. the truck should be right at 11lbs with a pair of 4s 5000 packs (4s 10000mah total)...

I think I'm going to tear down my 12000packs and make it a 800omah... I just don't need the enormous runtime and I would like to shed a few lbs.

I hate to take apart a perfectly good pack... but that's the plan right now.

I don't know much about the Lehners... never even seen one in person. But I'm sure a 1940 can do the job pretty well....

Hey, what's up GD?! Thanks for the info. I think I'm actually going to run a single 4s pack now. Maybe the 6000HV or 8000HV MaxAmps?

Sower · 03.05.2007, 10:04 PM

Dang it!! I just tried to order the 1940/9 and it's out of stock!! The only one available is the 1940/10 hi-amp. I really don't want the hi-amp. Crap!

Sower · 03.05.2007, 10:04 PM

Oh, I forgot something :mad:1 :035: :013: :019: :031: :026: :028: :007:

Sower · 03.05.2007, 10:18 PM

It's done!! I went ahead and got the 1940/10 hi-amp. I actually like that selection and think it will work really well. I sent Mike a note and asked him to make me a motor mount too. Hope he comes through on it for me. I'm getting stoked now!!:027:

BrianG · 03.05.2007, 10:29 PM

Cool. I think you'll be happy. What voltage do you plan to run on that? With a kv of 1568, you should have plenty of voltage options.

Sower · 03.05.2007, 10:32 PM

Exactly. Right now I'll be running it with 14.8 since I'll be using the Mamba Max esc. When the MMM comes out, I'll go to a 5s or 6s. Or more . . . ? Either way, I figured this motor would handle all those options well. With the lighter batteries than GD ran and smaller 1940 motor, I think I'll be about 11 pounds or just under. I think I'm going to be real happy!
