Some new packs Im testing

[nexgen]

The folks at OptiFuel were generous enough to send over a couple 6s 4300mAh packs for me to review. I will post my findings on these packs as I break them in and use them. Currently they are not sold in the US but OptiFuel is looking to start. If some of you guys from across the pond have used them feel free to post your results. Id like to know if any of you have flown these packs and what you think of them.

These are the very packs I am using in my Logo's.

Obviously still new as yet but really liking the power delivery they produce.

One thing I will say about these packs are I know for fact that a long testing program was applied and these proved to be a winner.

With current supply in the UK and a fantastic warranty makes these a very good purchase.

I've just got myself a pair of 6s 5000mah packs for my 600. First flights today so early days but they came off cooler than the FlightPowers.

From me singularly the market isn't very big but I would be interested in a 1300mAh 6S pack if it were the same size or smaller than the Voltz 6S pack.

I would expect interest from others now that Align are gearing up for 6S power of the 450.

Here is a video of Hf user akamullen flying the OptiPower 6s 30c 4300mAh pack. This is after about 10 flights on this pack, and it is turning out to be a strong performer. It will be interesting to see how these packs perform over time; after 50 flights, 100 flights, etc...

Here is the ET log from the above flight:

here are a few ET graphs of a controlled flight, comparing the OptiPower 4300mAh 30c packs with one of my Hyperion EX 4200mAh 45c packs. They are almost identical, with the Opti Power having slightly higher voltage at the end of the flight. The feel in flight however was about the same between the two. For this flight I flew the same routine for (as best as I could) the same amount of time, the flight was as follows:

Idle 1
Hover 10 seconds
full pitch climbout 5 seconds (13º pitch)
full negative decent
3 front flips with full cyclic
two power loops at full speed forward flight
30 second hover

then repeat the same thing in Idle 2

Internal resistance looks great, as you can see it is very low and fairly well matched:

pack 2
