According to David Gray, owner of Progressive RC, anything more than a 35C is a waste of money. C ratings are arbitrary, and chosen by each manufacturer, there is no standard or regulation they have to follow.

this is true , I have thunder power packs of 70 c and 45 c and the 45c feel like they have more power, they both have the same number of flights as I got them at the same time.

35C
Seems to be a Great balance between performance and costs. I bought some new 65C & 45C packs for my 800. Can't tell the difference.

The 35C packs are consistent and have good punch.

Although overseas packs ...seem to be rated different. 30C vs 35C here is a big difference.

**No name dropping, but you can guess which ones.

30-->45C

Does not slow me down at all from beating on my heli's. 99% of us have poor collective management when compared to the pro's. They can therefore get more out of a 30C pack than we can. that said, a 30C pack is not what is going to stop you from any 3D maneuver; but your skills will (not meant to be a jab at you).

From my lowly understanding a simple scale model won't need more than 25c and will never see a drastic pitch loading unless configured to do so which is rare, as in 3d. 3d systems almost always are on the gas pedal to the metal and I believe anything over 45c is overkill.

Go try a 45c and then a 25c battery of equal mah and v and test how they differ in simple scale type pattern and some prolonged pitch pumps aka pogos, then test how hot each is after a typical flight and how hot the motor is also.

25, 30, 35c there's very little difference if any however if your motor is working hard all the time it is drawing more amps to power through the work load and strain you put on it. A higher c rated lipo gives the motor, servos and esc more headroom to draw from.

3D you are always on/off the throttle. Big air flying you are on the throttle/collective more of the time and actually drains the batteries faster. Less voltage spikes but drains much faster.

I have 35c and 65c packs (Thor) that I use on my logo 550sx. The 65c batteries definitely hold the head speed better through the flight compared to the 35c. Especially when I am heavy handed with full collective and am flying in idle up 2.
If I fly more of a smooth flight in idle up 1, no, I can't tell the difference between the 35 and 65c packs.

30-45 for the most part, I do have some 65C Thunder Powers, and a 70C too, can't tell in these early stages if the extra C is going to yield any reward...

i noticed a huge difference going from 20C to 40C years back

but in recent years anything > greater than 40C yields very little improvement in my personal experience.

Note: i do not use expensive brand name batteries (i.e ThunderPower)

I also got a TP 70c near the end of last summer. It never outperformed any of my other lower C packs. And, even though it was in storage charge, lost cell 3 somewhere between January and last weekend when I went to charge it up. Yay.
Cell 3 actually went from it's 3.83 V storage charge to 4.20V by itself! Kinda scary. Between this and some past experience, I am done with TP.

I keep telling myself" no more thunder power packs" as I've had a few go bad mainly due to the balance plugs or wires being faulty, but then every year or so I send the old packs back to tp and get the brand new chemistry for half price, I have 5 tp packs now that get renewed every couple of years, this is the only reason that I still have them as I don't think they perform better than any other , cheaper packs that I have, my pulse packs are holding up very well and at 35c are just as powerful as the 70c tp's!

I'm not impressed with TP either. I bought some used, in very good condition, for about half price.
I immediately changed out the PITA balance connectors for JST/XH.
They are 45c & 65c and work just fine...I'll never pay their price for new ones though.

For last year's flying, my first season with the 550sx, I had bought the TP 70C, Thor 35C, Thor 65C, and Pulse 65C packs. Of all of them, the Pulse packs were the best at keeping up their voltage for the whole flight. They are my go to packs for now.

The only main brand I haven't tried yet is GensAce.

20c packs are more than enough for 99% of setups and flying styles!

60% of the time, it works every time!

30/35c have been my everyday workhorses for years and plenty happy with them. Do have one 45c
6s 5500 Thor that has been a great powerhouse pack.

I have a bunch of 20c hobby people packs that outperform many name brand high C packs, both in power delivery and longevity. Seems like my expensive packs always disappointed. However, some of my hobby king packs never delivered the value they promised. Not even close.

C ratings are not a standardized measuring tool. All smoke and mirrors when comparing between brands. Looking at C ratings within a brand can indicate better cells, though.

Enjoy things that money can buy IF you don't lose the things money can't buy.
