Anyone want to help electrify a 30 inch HLG to become a Parkflyer?

Howdy all-

I need 3 or 4 builders to convert our newest plane "FRY" to electric and post their results. You will need to document the build with some photos and posting to this thread.

The all up weight as a Hand launched glider is 4 ounces or so. Im thinking a speed200 or speed300 for a small area outdoor electric. A speed 400 would be WAY TO BIG.

Flies great so far, really light in the air. Should do fine up to 6-7 ounces and still be a good powered glider. We are looking for something that will handle winds up to 5 or 6 mph.

Wingspan is 30 inches. 150 inches square wing area.

We are looking for help on the electric modification. I will not charge full price for these test kits since you will be helping with the design, but I have to charge 10 bucks plus shipping. You will recieve foam wing panels, foam fuse pod and instruction sheet with simple plans. If you are interested, Let me know via email.

Here are some photos and a couple of links to a video of the plane. It was designed for SAL launch so if you electrify it, it could use a more conventional tail.

There are two versions of the video (different compression/file sizes), I recommend the larger MPEG as the quality is much better. Here are the links:
(MPEG, 30MB)
(WMV, 11MB)

Don't need a kit, but I can offer advice!! A IPS-A with a 9x7 or a 9x4.7 GWS slowfly should be good, mated to a pair of 2s 700 or 350 cells. Or you could use a IPS - C (C and A refer to gearings) with 3s 700's or 350's and a 11x7HD GWS prop, and you should be good to go!

The GWS slowfly props are more paddle shaped, and the HD props are rectangular.

Thanks Cam!
Should be pretty neat to see how they turn out- different gear and different builders

For brushless I'd go for the LensRC motor. Should be great. What kind of shipping charge to 42164? Motor and ESC ready to go.

I am not familiar with the LENSRC- how much thrust and what do they weigh?

Here's a more exhaustive thread on the motors.

BTW, your e-mail was returned as well.

Thanks again.

I took a look at his site- and think they might be a lot of fun to work around.

I like working with smaller companies- maybe he'll get a link on the plans or the webpage- I am impressed with his work.

Is the "FRY" available yet? I would love to order one.

The SAL FRY is not fully released, but I still have some pre-production kits for sale.
$15.00 plus $7.00 shipping to USA addresses (btw- I can send up to 3 in a box) gets you a foam wing core set and a foam pod with whatever version of the instructions we have done at the time we ship (they are fully written 20 pages- just no photos added as of today...just not polished) and full size templates for the tailfeathers. When the instructions are done and everything is released this should be a $20.00 setup. We think this will be next week.

Really fun little plane.

What is the tail boom made out of?

The tailboom is made from whatever you choose- In the photos, they happen to be balsa stick, either laminated or single. Carbon rod works best, but laminated balsa with carbon tape works great and is much cheaper.

One of my originals is still flying with a single piece of 1/4 by 3/8th balsa stick for a tailboom.
