"Old thread I know...
But yes....there should be a way to get warned that the aircraft will not have the climb/descent performance, or better yet to essentially guarantee that the aircraft will reach the waypoint altitude before moving on to the…"
"There seems to be a lot of discussion on the difference on 3S vs 4S. I would like to hear from those who have put a lot of weight on kit 3D-Robotics quads running the motors sold in the store. I started a separate thread about lift capacity…"
"I agree with you ... I have been using zippy's for 3 years now ... and am still using the same ones ... must have been recharged at least 150 times a couple of my turnigy are going puffy after 2 years of heavy use ...but am very happy with…"
"On motors/props I've personally tested on a net lift basis (it has to lift itself first), lower KV is on average more efficient. I started testing in the 800 to 1100 range. Now I don't waste my time searching for perfection…"
"Hi Forrest. I´ve been reading this forum and I would lke to ask you if you know how much KV will affect efficiency.
Let me be specific. I have a Tricopter and currently I´m using Turnigy Multistar 4220-880Kv motors. I actually…"
"On the efficiency of motors between 4S and 3S, that is all empirical test stand data (no equations). It varies a little by motor, but all have the same basic trend. So there is no math (besides comparing efficiencies in percent form).…"
Would you supply the math for the percentages? if any of these are calculated at 1%-2% for any idea then really the choice is mute and the advantage is negligible. At a 1%-2% calculated difference there are too many variances you would not…"
"It depends on your motors, flight load, and wiring.
o Gate 1: In 3S at the AUW you desire to fly, does the copter have enough lift at the end of normal battery drain to keep the copter in the air?
If no. Then must go 4S.
o Gate 2: Is…"
"I have had a lot of luck with glacier lipo's from buddyrc, anyone else using them?? Probably bought 25-30 packs from them now, zero issues. 55$ for a 3S 35c 5300mAh, 35C, 11.1V, 3 cells, 138 x 40 x 31 mm, 420g, 14.8 oz..."
