hello,
What receiver batteries are the best for a nitro powered heli? I'm using sub c nimh 5000ma and they don't seem to last very long.

2s the way to go..
I gave up on ni-cads and nimh about 5 yrs. ago..I've been running 2s packs of varying sizes in my 600n and 700n with Scott Grey reactor X's with great results.

I do a great decending funnel!

This totally depends on your servos and flying style. First, can you determine how many mah's you are using per flight?

Enjoy things that money can buy IF you don't lose the things money can't buy.

I agree with Tyler, that's a true statement. I don't fly hard esp the 2 nitros I have bc they're older and can't find any parts really for them so I take it 'easy'
On 1 I use a 2s lipo and the other I use a LIFE battery. No issues with either one. Again tho it's a basic simple setup with these 2 helis only.

which life battery are you using? I'm leaning toward a life battery, not sure which one.

For RX batteries I really like Glacier batteries (both 2S LiPo and/or 2S LiFe) from buddyrc.com. I have some that are at least 3 years old and perform just as they did on day 1.

All my ships have Glacier 2S LiPo's in them for the RX/servo power. As a reference, I use a 2600mAh 2S LiPo on my "3D" pod and boom nitro heli and easily get 6ea 6 minute flights before I get to 70% on the battery. A 2S LiFe battery I think would similarly.

Determining your battery consumption is a very critical step. I had a set of servos that would draw 1,200mah per flight. Yep, you read that right. I couldn't believe it when I discovered how hungry that set of servos was. I now have servos that draw only 200-300mah per flight, and they are stronger, faster, and I fly more aggressively.

Charge your batteries, charge them, record how many mah you use. Do this for several flights.

heys guys wondering about this what advantage does li-po have over ni-cads? Is it the charge time? Our size? A 2s would be 7.4 v right? I could see that and what coector are you guys using in the rec wire?

I think you might need to clean that up a little.....

Been there, done that and old enough to know better.....

IMHO..
1-you don't know how long nicad and nimh packs have been sittn around when you buy 'em these days. 2-Lipo's are lighter. 3. As they age you will have much more confidence using lipo's..nicads and especially nimh get damaged over time self-discharging. 4. With lipo's and a good regulator you can tailor the voltage to your components for best safety and performance.I was skeptical about what might happen in a crash..but turned out to be not a problem..and oh yeah..lipo's are cheaper in most cases.

its best to get a 10C LiFE pack of say...1800mah or more.

you will need a regulator if you don't have HV servos. Castle makes a nice 10 amp unit for not much money.

Yes.. you NEED A REG with LIFE packs if you don't have HV servos.

Bummer I know.

I've used the hobbyKing 2s 3000 Life batteries for all my Heli's and airplanes... as a rule I'm seeing about 300-350 mils per flight (Savox and Hitec servos)... what this means? I can fly all day on one charge... I do run a separate 2s 3000 for all accessories (landing gear, lighting, etc) never had an issue....

IF you have a charger that can charge LiFe, consider A123. No regulator required for most tail servos..

I use a life pack and it works really well. Gives me a better piece of mind versus my old Nimh battery packs.

mine flys about 250mah per flight...

you will love the LiFE packs.. make sure the charger you choose allows charging LiFE.

ENJOY. no wrong way!

I go over kill and parallel (2) 2 cell 1100mah A123 life packs for each nitro heli. I recommend cylindrical a123 cells which are very robust and can handle ANY digital servo load or stall.

Contrary to above, I have run 2s A123 (same tech as LiFe - both 6.6V max) batteries in 3 electric scale helis for years (I built the Long Ranger 7 years ago), and have never owned a regulator or a HV servo.

Most of my servos are 6V rated Futaba BLS252/BLS451, but I do have one BLS254 (4.8V rated) that I run with a simple Align step-down.

So, in my experience, you DO NOT need a regulator for a 2s LiFe if you have decent servos that are rated for 6V. Now if you do not get 6V rated glow plugs etc, I do not know because I have never owned a nitro heli, but certainly for 6V servos, Rx , FBL etc, not a problem.
