Logo 10 convert to 4S LiPo - opinions wanted from 4S flyers

[ncpiperpilot]

I'm a Logo newby and I'd like opinions on conversion to LiPos (or A123s) please...

My Logo 10, that I just bought in great used condition, has been run on 12-cell 2400SCR NiCds and 13-cell GP3300 NiMH packs. It has a Kontronic 600-18 motor and Schulze 18.46K ESC. I have 13T, 14T and 15T pinions, with the 15T currently installed. It also has 515 MS Composite blades.

I figured I would continue to use those packs for now while I feel out the heli - flew the first time this weekend for 5 flights - hovering and FF only. Great Heli smooth and easy to fly. I am not a 3D flyer, maybe I'll do a roll or loop, but not planning much else other than FFF/circuits really.

The challenge here of course is whether to stick with this 4S motor/ESC or re-power with something like a Z30-1100 and a CC 45HV and go to 6S. I'd prefer not to spend all the money now, but if I am going to buy the LiPos I'd also hate to waste the money.

So...for those of you flying 4S setups, what packs (and motor/pinion) are you using and how happy are you with the results? If someone has A123 pack experience running 5S (or maybe 6S) I'd sure appreciate those too!

Thanks,
Bill

Just wondering;

Would this Neu work on 4s?

I have a Logo 10 with same motor, but using a CC60 esc on 4 cell lipos. I was doing forward flight, but no 3d. It seemed to do everything I wanted. Not sure about bogging, I was running the 13T pinion. I was running 4S2P 4400mah pack and getting 8 minutes. The motor threw a magnet, so I have a new 600-17 motor on the way. I am in the middle of changing it over to the Logo 14 gears for the tail, but I don't have any numbers yet. I will be running the Logo 14 138T main gear with a 12T pinion. I couldn't get a 10T pinion, not in stock where I bought the parts. When I get the new motor and everything back together I can let you know how it is.

Thanks Terry,

I do wonder if that 15T pinion is to high. Do you recall the headspeed you were getting on 13T w/ 4S and the 600-18?

Thanks, Bill

I never put a tach on it to find actual headspeed, but the calculation was approximately 1800 rpms. I did ff and circuits and was quite happy with the performance. By changing to the Logo 14 tail, the 600-17 motor, and gears with a 12T pinion the calculation is almost 2100 rpms. It will be interesting to see the difference when everything gets back together.
