Battery for Futaba R127DF
 

I tried doing some searches, but didn't come up with anything.

I've got a Thunder Tiger trainer with 4 servos and a Futaba R127DF. What size battery should I get? From what I've seen in the searches, a 6v sounds better than a 4.?v

A 4.8v is fine for a trainer, a 6v would run down faster too.

What size mAh?

600 should last you though a day of flying (6-7 flights), you can go with a 1000-1200 if your a person that flys from dawn to dusk.

You can go with a 600 mAH. That is the size battery that comes with the flight packs. I am running 5 servos on my 4 star and had a total of 2.5 hours of actual flight time today (according to my timer on my 9C). I checked the voltage after that and to my amazement the batteries were showing 4.77 Volts and that was under a load. I was surprised!! Remember, Backwing the larger the battery the more your plane will weigh, and with a trainer you want to keep as light as possible...

Just use li-poly's, it's a bit more expensive but as far as flight packs go you can't beat the power to weight ratio.

My UltraStick 120 has a Futaba FP R-127DF receiver, six BIG servos, and one little servo for the throttle.

Even with the big Saito hung on the front with a 3 1/2" metal spinner over a big three bladed prop, I needed more weight in the nose.

And on the shelf I had ten brand new Sanyo "D" size NiCd cells.

The UltraStick now has a 4500 mah battery pack in it.

I can fly all day, recharge my transmitter battery twice, and give a couple people jump starts for their cars, all from the airplane battery. And do it all a couple more weekends before I need to recharge it.

That is a slight exaggeration, of course, but that's about what it seems like.

The moral of the story (what story? Who cares) is to use the highest capacity that you can get in the plane AND your transmitter - considering weight, of course - it's cheap insurance.

And unless you want or need the extreme speed, stay with 4.8v sets.

Bill.
