Having recently purchased four 6s 6200mah racing packs at 90c to try out on my Viper and Super Scorpion, I was expecting a better punch into vertical maneuvers, a little more power delivery all round & a touch more endurance if that was not asking too much.
These packs delivered all of that on the power hungry 90mm EDF models including a marked increase in performance on the Freewing Raptor too, all getting away more cleanly from our draggy damp grass runway with a punchy positive climb out on rotation...they feel more determined and meaningful in flight..so these cells are all I will buy in the future at this sensible price point and also for their incredible IR values. I have used so many brands over the years, some claiming to be the best in the 100amp current draw category but only two other brands can compare to the stability under load as these racing packs. What reveals their true value and is the real test of their robustness under load is to measure the residual energy levels after each flight. We all do this to know how close we came to an empty tank and adjust our 4 minute timer setting accordingly ....well there was often 45% left down to 30% on occasion after a go around. They do not gush their electrons ...IR still holds at 1mOhm even after frequent use so I am hopeful for longevity from this brand too. Time will tell as usual of course. I have started buying the 4s 90c 5200mah racing packs to make 8s for the Zeus which enables this stunning EDF to punch verticals to new heights and provides a far more adrenalin fueled flight experience, so delighted to have near turbine performance at last, finally the perfect combination to deliver the ultimate EDF experience on a realistically affordable out of the box package, the technologies have all finally aligned and I am just loving the thrill and the fun of flying these amazing electric jets.
