A question for all experienced heli flyers out there!

I am thinking of upgrading my standard NiCd batteries to NiMh but have read that the high current some servos draw under load can lead to the gyro resseting or even crashing the heli.

Would this only apply to high torque servos in 60/90 helis or should I be concerned?

I am using standard digital servos for my raptor 30 and was wondering if you guys think I should stick to NiCd.

I am thinking of 4.8v 2500mah NiMhs

Also I have a JR 10X which i bought used, and need to change the battery. I am also thinking of 9.6v 2100mah NiMh...any comments?

All opinions welcome!

Many thanks!

DK

I have a NiMH in my 10X. I have never had the transmitter run out of steam. I have used NiMH receiver packs, and have since removed them, as I don't see NiMH as an upgrade. I have had great service from 1700NiCd AU packs in the 30/50 machines, and 2800ma Duralites in 50 size and up. When I feel up to it, I'll be installing a Duralite transmitter pack as well. As always, YMMV.

I've since switched over to all Li-Ion Duralites in all of my helis and TX. It's an expensive venture with 3 helis but never having to worry about a charged battery is worth it to me.

I use a 9.6v 2100 mAh NiMh in my JR 9303 and have been since it was new. I also run a 4.8v 2100 mAh NiMh for my radio and servos. I've never had a problem with either one. I have been thinking about running a 5 cell 6v pack with a 5v regulator in my Raptor, but I have not changed it over as yet. I'm pretty satisfied with things as they are. I keep fully charged backups for both and have'nt had to use either on yet. I use a GEM 2000 battery monitor and would'nt fly without it.

Experience is something you don't get until just after you need it!

Thanks guys,

I have put an order in for the NiMhs,

will use for sometime until the need arises to upgrade the servos I have (currently just practicing hovering) in which case I will probably go with lipos and a regulator to be on the safe side.

If you ordered the 5 cell pack, you will probably need a regulator anyway as the pack measures over 7volts when fully charged.

Get the arizona fromeco regulator. Dual output with the second one fully adjustable.

Just remember to cycle the batteries 3 times before usage to make the most out of it. Use the 1/10C rule to charge it for the first 3 times. (C is the capacity of the pack, in your case 250mA).
