Hi dave,

"they arent anything new"

Evidently they are - in that the battery "system" IS working and providing sufficient power to do the job. The ones you have in your shop now do not, or at least nobody has demonstrated so yet.

Cheers!

Does anybody know the cell layout on that joker. In the video he said 8600mha and about 30 nicad cell voltage i think, so im guessing about 40V and 12 cells in series? Whats the rated wattage of the motor?

"what do you mean by mine arent doing the job?"

They cannot put out the 20 -30 amps that it takes to throw an 8 - 10 pound heli around the sky (and be a workable system) as is being done with the FlightEnergy packs. If anyone is doing so, they are being awfully quiet about it

I'm just relying on reliable eyewitness reports for this though......

Cheers!

Wingtip,

Glen is right. The kokams can't deliver that kind of performance that's why we heli-pilots have had to wait until the thunder power ones from flight energy were available.

Cost?

I would highly consider going electric with flight performance seen in these videos if the cost was reasonable. Considering the initial setup including heli, motor, esc, batteries, and chargers, it sounds pricey up front. I would really like to see some numbers indicating how many real-life cycles these packs will offer. many have argued that the high entry costs into electrics needs to be compared to the ongoing cost of 30% glow fuel. This can only be a real comparison if the batteries can withstand several hundred complete cycles.

I would like to know how much it costs to get that exact heli in the air:

Heli kit
upgrades
servos
motor
esc
batteries
chargers
power supply/field battery to recharge the cells
connectors

Then I would like to know how realistic field charging these packs would be. Considering the recharge time and power supply requirements, field charging may be out of the reasonable expectations of sport flying such a heli. Then the cost of additional battery packs would need to be revisited.

I typically like to get four full tanks through my helis when I go to the field. This is a minimum of 40 full power minutes of flight. How many packs would that equate in the Joker electric? How much does that cost?

Finally, I am concerned about the safety of such powerful batteries. What happens when the heli takes a dirt bath? Are the batteries easily or even remotely damaged in a crash? What about storage of the batteries?

I have often thought that the electric models had the potential to be smoother running machines by taking away the pounding of a piston, especially now that we are living in the times of big block engines. There is no goo to clean, gasoline to mix, glow plugs to change, ignitors to charge and remember to take to the field, on and on go the potential advantages of electric.

I am all ears as these technologies develop and become more common and affordable. Who can give us realistic and real-time prices on this option of flight?

Lots of Question

Boy Tyler, that's a lot of question. I hope someone can answer them for you. I'm just the poor guy that was handed the transmitter, and was told to fly it hard. It sure did handle like a 80 or 90.

Alan

Alan, You are a lucky one!!

O.K, so you have earned the priviledges of flying other people's helis because of your advanced flying skills. I sure would not be able to put a heli through its paces like you did in the video. I saw you fly at IRCHA this year and you were awsome.

So, give us a rundown of how the heli felt to you. Don't just compare the electric to glow power, but also compare the Joker to other machines. How crisp and solid is the collective, cyclic, tail authority, etc.

Don't hold out on us mere mortals....
