Hi all,
Thanks for the answers.
Mike,
I need a regulator for this plane, and as it is about a pattern plane I would like to use the lightest setup as possible. I believe that the one I chose is one of the lightest if not the lightest in terms of power supply. Just for your info the plane has 2 x JR 9411SA, 1 x JR 8411SA and 3 Futaba 9650 servos and is a glow F3A plane with a YS 170DZ.
With normal F3A flight you will use a maximum of about 100Mah per flight just flying the scedule once only, if you go beyond that then you will use more cappacity, all the suggestions so far except for the Kodiak only check voltage, the Kodiak measures Mah consumed which is what is important IMO, LiPo's will recover a certain amount of voltage after flight so may not give an accurate indication on voltage alone, but then on a 2000Mah battery you are going to get 10 flights if you are going to just do the schedule once per flight, and that is always enough for me, my concentration goes after. LOL
I use the Kodiak and A123's no regulator, weight for weight about the same if you include the regulator on any other set up, one other thing if any of the servo's you are using are digital they will consume more current than an analog servo so make sure any regulator you use is able to supply the current needed, IMO 4amps is not enough to be on the safe side. You can get A123'a in 1100Mah size which will get the weight down even more and as you can charge them at very high amps safely you could re-charge whilst re-fueling, the 2300Mah A123's can be charged at 10amps, not sure what the safe charge is on the 1100's, but will be higher than any LiPo or Nimh.
