OK, that's all I can find. Now time to start plugging in numbers and see what is going to work.

I think I have found the motor I need. But it works best on 4s. Motor link: http://www.leopardhobby.com/proviewen.asp?id=1080&sid=37&gid=73&pt=3
Run the numbers and see what you come up with, but I think we found a winner!
:banana:
Now someone is going to say those motors are junk. But I can buy two of them if needed. They are cheap enough. The hard part might be finding a 2.3 mm pinion gear with the right number of teeth.

Here are the two combos that look the best.
10 x 9 with 4.4:1
11 x 8 with 5.3:1
What do you think?

Since I hate it when people never follow up on their threads, and we lose valuable info, here is an update.
I got the gearbox in, and 11x8.5 prop in the mail. The motor should arrive today and I can start doing some flight testing shortly after that. I am expecting at least 40 minute flight times at 45 mph. Not too shabby!
Jim,
Noticed your calculator is down. I hope not permanently. It is a nice resource.

Jim,
Do you know when you calculator will be back up and running?
I'd like to see what the numbers are using a 10x10e with a 490 KV motor using a 4s 2200 battery.
Thanks,
Frank

I'm not going to tell you that Leopard is junk, but I will tell you to be careful with high-energy maneuvers. I've seen some of the earlier ones spit magnets in poptops and tumbles (I had one do that myself). Now, that was an earlier version of the motor, so the problem may very well be fixed. Just telling you to keep an eye on it...

Thanks for the heads up. That is the only motor myself and a number of RCGers could find that could handle a 4s battery in that weight range besides a Neu motor and I was lost trying to figure out what was best with the Neus let alone order one. So it was pretty much this or nothing at all so I figured it was worth a shot.
I could not believe how limited the motors were. I sure found a weak spot, but I guess the demand is not there. This motor was actually advertised for RC cars.

Jim,
Glad to see the Calc up and running again. Gonna try the 10x10 prop now and see if I can get some more fwd speed out of the motor.
Frank
PS I was reading over some old emails about flight times. Many people had doubted you could actually get 30 minutes of flight time at 40 mph on a 2200 mAH battery.
