What size would be equal to a 50 size IC?
-
Better yet what do you want to put it in?
-
Was thinking about a vector or SV 11 H^^

For the SV11 4 cell setup- http://www.innov8tivedesigns.com/product_info.php?cPath=21_120_122&products_id=840&osCsid=43161239709c9e3b48abf0086923a10e or this one http://www.innov8tivedesigns.com/product_info.php?cPath=21_120_123&products_id=846&osCsid=43161239709c9e3b48abf0086923a10e
If you want a 5 cell set up let me know
For Vector use the 2820/12 970kv or the 2820/14 840kv both should be ok on 4 cells

Thanks William.

Hey William:
I would like to know your recommendations for the Cobra 5-cell motor. Also would there be a significant weight difference in the battery pack needed 4 vs 5 cell ? Thanks for the help.

I'm not William, but the 2826/12 may be the mtr. you want, depending on what size airplane you intend to put it in. Crist Rigotti has been using this mtr. very succesfully on 5 cell packs. He may chime in here also untill William can respond to your querry. :) Just make sure you don't over-dissipate it. LL~

Allen,
The 2826/12 like Dan says or the 3515/18 should work fine for most of our needs with a 5 cell. For some the 3520/14 may be a better choice. I have no idea what you want to use it in, but those would be your 5 cell choices in the majority of applications. Unless you plan on using those super light Thunderpower 5s2700 mah batteries(10.5 oz I think) your weight for batteries stays about the same weather you use a 4 cell set up or a 5 cell set up. Less cells=lower voltage=higher mah needed. More cell =higher voltage=lower mah needed. So using very rough imprecise math (I'm no engineer) lets say a 4s4000 weighs 400 grams on average(I know I'm close), I would expect the average 5s 3000-5s 3300 to weigh about the same in most case as long as the C ratings are also comparable. If you go to Hobby King's website and use their battery heaven battery finder program and plug numbers in for 4 and 5 cell packs using the numbers I just gave you will see that this actually works. Don't forget to sort by weight after you plug the numbers in.

I bought a Cobra C-2826/12 Brushless Motor, Kv=760 for a 5s setup for a Brodak Bearcat. It is a copy of the AXI
Ill let U know what I think as soon as I can get it going.
