Correct me if I am wrong but you say you went from a 3 cell 1550mAh battery to a 2200mAh. You dont say how many cells but I am left to assume it is a 3 cell. If so, it shouldn't give you any more power, just a longer flight time. Your thrust is dictated by your motors kV (thousand revolutions per volt), your fan blade pitch and size, and your battery voltage. You change nothing other than the battery and, if you don't change the voltage, the rpm of the motor (thrust) stays the same.
@pgiustino yes, sort of. At 4:20 he says he put in the bigger battery and "it feels like it has a little more thrust" but then at 4:35 he says "lighter weight is alot better than heavier and more power". All he really did was put in a bigger "fuel tank" making it so that he needs more thrust to overcome the added weight. He would likely get added flight time, but not 40% more as the mAh size difference would make you expect.
@RCcunuk OOO hot debate going on here. =) Yes RCcanuck it was also a 3 cell battery that was 2200mah. Yes in theory all it's doing is adding a larger "gas tank". However there is a certain point with batterys that the actual size (mah) of the battery makes a difference in power. For example a 500mah 3 cell 25C lipo would not have as much "power" under full load as say a 4,000 mah 3 cell 25C lipo. Under high loads there is so much demand for energy that a smaller batt just can't dish it out.
@MikeysRC I am fairly new to RC but here is my understanding. Please correct me where I am wrong because I am here to learn. The more cells in lipos, the more voltage (3.7/cell), the higher mAh (milli amp hour) rating, the more energy (electrical power) it holds, the higher the C rating, the higher amp draw available (more amps to turn a larger motor). I don't understand how, by only having a higher mAh rating, with the same C rating, you can produce more rpm with the same voltage
@RCcunuk Because even with everything else being the same except with a smaller mah when using a power system that draws gobs of power from the battery a smaller battery just can't give as much "oompf" as a larger battery. Sure the difference between say a 2200 and a 2100 would be neglagable but the difference between a 1550 mah and a 2200 is significant enough to show a slight differnce in "avaliable under load" power / energy between the two batteries.
@RCcunuk By the way KV is RPM's per volt. So voltage = RPM. Bigger RPM, higher speed/thrust.
As for batteries: voltage in baterieas can be lost in 2 ways - load and discharge.
Load: C raiting only determines phisical destruction point of it. On 9A load for example 1000mAh 10C will give more punch than 500mAh 20C although max discharge is rated at 10A. Phisics...
Discharge: LiPo discharges exponentially wen it comes to voltage; bigger capacity, longer hight-point of exponent.
@DefekCs OK, correct me if I am wrong. If you have 2 batteries, say 1000mAh and 2000mAh, both are charged to 12Vdc, both will start off with the same rpm but the 1000 will drop off sooner because it discharges faster and loses voltage sooner
@RCcunuk Exactly! Bigger battery can keep up to its rated voltage better. Smaller batteries will become week faster, and not because it is rated wrong. It is simply physics... ;)
good video, but I like the gliders more:) It can fly way longer because of the long wings and you can like turn the motor very low and let it fly very slow and for a very long time.
Can you make a giant glider?:O I would really love to see that! And then like throw it of a building or something.

@RCcunuk The "C" or current is a ratio of the mAh. So a 1550 30c wouldn't support as high of an amperage draw as a 2200mAh 30c.
