Electric
aircraft project.
I want to build an experimental electric
aircraft and will need additional funding or grants to cover the cost. Anyone
interested should contact me hankkroll@gmail.com Once we learn the technology and
get project off the ground (literally) I will put a video on you tube and use
my company, New Wave Technology to do additional conversions.
Sikorsky has a full
sized battery powered helicopter prototype on you tube. Check it out! It uses a
US Hybrid electric motor and two Lithium battery packs weighing 700 pounds each.
Not to practical at the present time. I believe battery technology is on the verge of making electric powered flying machines possible.
The
battery packs that I think will work each weigh 135 pounds for a total weight
of 270 pounds. The 110 AH at 48 volts batteries can sustain a maximum discharge
of 30 amps and 20 amps continuous. Both battery packs hooked together can
deliver a maximum of 60 amps for one minute delivering 80 HP. I believe the plane will fly strait and level
on 30 HP.
Since
there will be no engine, gasoline or fuel tanks to worry about the battery
packs, electric motor and controller will weigh slightly more than the battery
pack and the electric motor. When sitting at the airport solar cells could be
used to charge the batteries.
I
recently sold my J-3 Cub so I have some money to put into the project. It has
to fly at least two hours carrying two people. The Challenger II kit aircraft empty
weight is 350 pounds and cost about $20,000.00. Two Lithium ion battery packs with
a controller cost about $20,000.00.
I
have been researching the new lithium ion batteries and electric car
conversions for some time. There is a tremendous amount .of information on the
web right now regarding electric car conversions.

A propellar
hub will be fixed on the motor where a three-blade ground adjustable carbon
fiber prop is mounted. The Challenger is a pusher configuration so there is no
danger of the hub coming off. As I said before we need 50 hp for takeoff and
about 30 hp for level flight. Your smaller motor is what I need the price. Just
give me a price.
One option is
two Lithium Ion 110/ah/48 volt battery packs each weighing 135 pounds put out a
maximum 30 amps each. Both will be used for takeoff for a total of 60 amps for
one minute (96 volts with bot battery packs) a continuous output of 20 amps
each (total 40 amps with both). I don't know if it will fly on 20 amps.
Greetings
Henry,
We may be able to help you out. Please let me know a few more things. We must obtain a schematic or picture of your Challenger kit aircraft design?(Without that we cannot progress.) What differential or mechanical design will you require from our motor?(Straight output keyed shaft? Length? Splined shaft?) What are the total AMP hours for your exact lithium batteries? Let me know. We look forward to working with you on all your electric motor and controller needs.

I
will adapt the keyed shaft to the prop hub. I have a metal lathe. Just send me
a price for the 50 or 70 hp motor at 140 volts and the controller.
I
can buy the blank prop hubs from any number of aircraft suppliers. I will bor
it out myself so its not a problem. The keyed shaft would be best with a bolt
tapped into the end. Being that the Challenger aircraft is a pusher
configuration the prop will not come off.
We

that we cannot progress.) What differential or mechanical design will you
require from our motor?(Straight output keyed shaft? Length? Splined
