Default Need Brushless can't decide please help!!!!!

Hey guys could really use some help here. I've been flying electrics for a while now and want to move on to brushless.
I want to get a brushless motor that I can use in many different
airplanes. I've been looking at the different ones, reading over the forums, and I think I would like to get a Mega.
The problem is which Mega to get. I need one that is comparable to the 400 or 480 motors. I have the Wattage Impress, Wattage Decathalon, and Zagi, all of which are 400 to 480 sized motors. I plan on getting one of the GWS warbirds, and the WATTage CAp232 (FYI 232 on sale till end of AUG for 99.00 at HP) or Giles. I've been to www.e-flightline.com where they have put the mega 16/7/7 on the GWS warbirds, but for the CAp 232 I'm looking at something more like 16/15/4.

So if you guys could suggest my best bet. I'm looking for the Mega motor that will best fit in between these two. Or if I could get either one and just gear it for the plane. I was thinking of getting the 16/15/4 with some gear boxes, and possibly using LI-polys.
Along the lines of the Li-poly does anyone know where I can find the best deal on a good charger for the Li-Polys?

Any help would be much apprieciated.

The Mega 16/15/x series are great motors, but, they are intended to be primarily used direct drive. This helps keep the weight and complexity. This is also why they come in winds from 2-8 turns so you can design your optimal system.

Keep in mind that there are grey areas in the design philosophy that allow for flexibility like gearing. I think that you are on the right track with your 16/15/4 choice.

I have only used the Mega motors in direct drive applications.

My Wattage Extra 330L uses the following combination:
  • Mega 16/15/7 direct drive brushless motor
  • AeroNaut 10x7 black carbon prop
  • RTF @ 24.5oz with
  • 8-HECELLs or 500AR cells, 15amps @ 6100 RPMs, 100 W, 6.0oz pack

An 8-cell, CP1300 pack provided, 19amps @ 7000 RPMs but the 10.6oz pack increases the RTF weight to 29.1oz.

I have a new Lithium pack that I will test soon. The 3s3p pack is made from the new Kokam 340SHC cells. It has a 1020mAh capacity and can deliver 20amps continuous but it weighs only 3oz!

My little Extra will be RTF at only 21.5oz and it already has awesome vertical runs!

You can see pictures about half way down my Aerobatics page.

My other Mega application is the 100mph ProJeti using a 16/15/3 motor.

Details are at the bottom of my Wings page.

Good luck!

Default zagi brushless

I prefer the mega 16/15/3 over the 16/15/4. you get more thust if your swinging a 5x5. the 16/15/4 works best if you plan on using more then 8 cells, say a 10 cell zagi pack for instince. after trying many options the 16/15/3 with a 5x5 worked the best. as for other aircraft as long as their wing loading iand size is about the same then this combo should work as well. I swiped this combo over into my mugi that I hand buit and it works awsome.
