9L vs 10L vs 7XL (14 cells) - Page 2 - RC-Monster Forums

I get about 10 mins of runtime on my 10l with 14 cells.

As far as the speed thing, I can't help you there I have only run the 10l and I don't know the speed of that thing.

I was getting an easy 13-16 minutes on Gp3300's. My speeds were around the 38mph area. Now with 16 cells, im around 42-45.

All those speeds will be similar, if they are geared for what they are supposed to do. But out of those three motors id take a 7 xl. Why you ask? well...

-Longer runtimes
-Cooler motor-therefore more efficient
-More power
-Can gear up to compensate for lost top speed.

Any more questions?

Thanks! I am leaning towards the 7XL as well. What type of gearing is typical for a 7XL on 14 cells (32P, Stock spiders in aluminum cup)?

Definitely looking for a whole new setup..just picked up a 9920 from MetalMan. Just need the motor now. Oh..BTW..I have the "L size" heatsink/clamp on my 9L right now..what length screws would I need to get it to work on a XL motor? I remember reading this somewhere..but can't seem to find it now...

BTW..what is the length on the XL cans? Still running stock chassis that's why...

I think it is like 74 mm long. That is not including the shaft though.

thanks CHC :)

To get the L/XL heatsink clamp to work on an XL..I need longer screws, right? what size?

coolhandcountry · 04.29.2006, 08:14 PM

I would get the xl clamp. It covers the motor all the way and looks nicer. helps with cooling to.

infinite_loop · 04.29.2006, 08:18 PM

Yeah..but I already have the L/XL clamp that I'm currently using on my 9L

coolhandcountry · 04.29.2006, 08:45 PM

Oh! I thought you was going to buy one. It is a 10mm difference in length. It screws in a few mm.I would go with 15mm or so.

infinite_loop · 04.29.2006, 09:22 PM

Yeah..if I sell my current setup..I was debating whether or not to sell the heatsink I have as well. But then I'd have to buy a new one, meaning more money..LOL

Thanks for the screws info! :)

If you get it off of mike.(the motor) Ask him to hook you up with the right screws for it.

infinite_loop · 04.30.2006, 03:04 PM

good idea..I'll try that!

I have a 9L and 10L feigao motors. What gearing and how many cells should I use? 12, 14, or 16? I'll be using a 9920 esc.

16, how many teeth does your spur have?

Bmr4life · 05.05.2006, 09:35 PM

72 teeth, but I can always buy another one.
