e-Miniature Aircraft Furion - Razor - Ion-X > Ion on Round Cells

I got an Ion-x with hacker motor/controller for Xmas (I must have been a good boy eh!) and am just starting to put it together. I would like to postpone going to Lipo's for a little while longer until this technology improves a bit more.

I fly my Logo 16 (basically upgraded to a Logo 20) on 20-2600 Nimhs and get 8-9 minutes flight time (sport flying with light acros and 1650-1700 rpm headspeed). I've just ordered a set of 20-GP3700's to try out. These should get my flight times up to well over 10 minutes. These cells weigh about 2g each more than the GP3300 and the new GP3700's are supposed to have about the same/or more grunt.

My questions to you all are, for optimum sport flying performance and flight times (say ~1700 rpm):

-How many cells should I use (28, 30,or 32 cells)?
-What are the best, most efficient rotor blades, and
-At what gearing should I use, believe I have a 55t main in my kit

Thanks for your help.

Cheers,

Hi Tom

The machine will fly fine on 28 to 32 roundcells (I liked 28). Although I'm not too current with the newest stuff, back when I was using roundcells in the machine, the CP's and HRSC's worked well. You will most likely want to change the gear ratio a little, probably down numerically. Start with what you have and then if you want more headspeed (or less) we can work from there.

What kind of flight times can you get out of round cells?

Oh you know, it all depends on the configuration and flying style. Turn the head at 1600 to 1700 and fly the heli gently and in a momentum conserving way, you might be able to squeak 8+ minutes out of the newest high capacity NiMH's. Set the machine up for 1900 on the head and yank it around the sky, expect 3 to 5 minutes.
