| The same size e-heli makes 500 flights on these here Lipos, which cost $250.

wrong wrong wrong wrong ....... 
I have an e-Raptor 50 swinging 600mm blades running a TP PL 10S2P 4200 on a Neu 1912-1.5y which is a very efficient motor on a CC45HV.
This is a very smooth, safe and 3D capable setup for any stick banger. I consider myself to still be a beginner and my flying is more like an ugly 3D style.
With the Thunder Power Prolite 10S2P 4200 ($550), I can fly a T-Rex 600 just like the Raptor 50. Same weight, same blades, same HS.
Just for kicks, I put a Thunder Power PL 6S2P 4200 pack that had around 60 cycles through it on the e-Raptor.
After 3 flights the lipo puffed and now it's toast.
That is a realistic real-world figure coming from an average flyer.
I'm not a pro and do not have the collective managment skills to fly my Raptor 50 with a TP PL 6S2P 4200 without stressing out the pack.

| Now I have no idea on the accuracy of this statement, I have not done my home work so shoot me down if I'm wrong. I am also not familiar with the emoli cells being discussed. With batteries still costing this much do we really see this class of heli flying  of the shelves? I can accept that the prices will continue to fall, but with the Trex 600 due to hit the stores soon these prices are still valid! How many cells would you realistically need for a days flying?

Gazzer,
I cannot see the prices of lipo's dropping so significantly that the 50 size heli's will be affordable.
Look at it this way, if a 10S2P 4200 is $550 right now, and a TP PL 3S1P 2100 is $65, then with that math, cut the 10S2P in half and the 2100's will be $30 ? I can't see that happening.
I have two Thunder Power Prolite 10S2P 4200's for my Raptor 50 that gives me about 8mins of flight time each.
That is a real figure.
$1,100 of lipo's for 16-18 mins of flight.
Now, you have the cells by Moli Energy.
I have a set of those as well. I'm running two 6S1P 3000 moli packs in the Raptor. One pack up front and one below where the tank used to be inside the frame. And using a 2S1P moli pack to run the rx/servo's,etc..
That nets me about 5-6 mins of flight time.
Those are much more affordable by far.
7S1P 3000 Milwaukee v28 pack on ebay approx price $ 100 / pack.
Four packs = $400.
So, roughly 1/3rd the cost of the TP Prolite's.
That is good IMO. 
... But honey it was only $$$ |
