Hi All,
i have just traded up from 40 sized models and standard servos to a very nice Hangar 9 pulse XT 60 (Saito 100). On board I have 4 Futaba S3050 digital servos and a 3010 on the throttle (+ Aurora 9 radio). Because of weight/balance issues I went for a 6V eneloop 2000mah receiver pack rather than the Nicads I usually use. A member of my club advises strongly against this set-up, cautioning against large voltage drops with this many digital servos in a large-ish model, presumably due to the high internal resistance of the eneloops. A quick google etc sees lots of information out there cautioning against using NiMh receiver packs in high drain applications and it all makes sense to me. My question for you very learned people is whether "high drain" in this instance is referring to large models like 30% IMAC etc etc, or whether I should really have some concerns about my set-up, especially if I fly it "hard"?
I guess I can always go back to the Nicads, or invest in some A123s (+ new charger!). Also I assume that both the receiver and the futaba servos would be happy at the 6.6V of the A123s.
Advice appreciated!!!! (I have read Bruce's article on batteries)
Many thanks in advance!
best to you all
