Good question. I've been looking for same. My Sky Surfer needs a park-size area to move around in. My first indoor attempt will be this week in an enclosed horse arena here in Houston, but it's a huge area. I know of no commercially available indoor/slowflyer PPC's(powered parachutes)so I'm going to build one. There are a couple of sources I know of for ram air canopies(parachutes)but they are intended for 400 motors and up to gas engines. They are: www.powerglider.com and www.airfoilaviation.com you may also try searching the web for "kites". There is a lot of parafoil kites out there that MIGHT be adapted for what we want. Please let me know if find anything worth trying. Thanks.

well, i've found a lot of parafoil kites, but the smallest SUITABLE one was 50", you'd need a s400 to haul that thing around. herm...

Hey Tom, our first obstacle is finding a ram-air parachute between 18"& 24" wide for indoor use. The 50" size canopy i.e. SySurfer is too big.

Woo!! ok, i've found a semi-suitable 'chute to use... check it out: http://www.eskimo.com/~4winds/dgf/gf.htm#para1
scroll down until you get to the pocket parastunter...

36" span, 15" chord, weighs 2 oz. still not as small as i had hoped for, but it's getting there!

Your on the right track. That's a larger version of the kite I had until it got parked on a lite pole. Never got a chance to motorize it. I think it has the right design with minimal rigging of needed cascade and control lines. I do remember when flown like a kite,it needed the minimum 7mph of wind(see specs)to fly right. That's getting up there speed-wise for some indoor areas. Anybody know what a Lite-Stick cruises at?

I got a lite stik, it cruizes at... 5 mph or so, i think. if a 55" chute can be powered by a speed 400, than this 36" chute seems like a good cantidate for a geared speed 280, or a DD 300. but yeah, 7 mph kind of eliminates the advantage of having a smaller chute. actually, it's gonna have to fly FASTER than that, as 7 mph is the minimum of wind needed to lift the chute. so, i'm guessing that it'll fly 'round 10 mph. still fun, but prolly too fast for indoor flight...

Hmmm... 7mph may be the wind needed for fun stunt kiting. At 7 oz the wingloading would be under 2 oz/sq ft... are powered parachutes inefficient enough that they need to fly faster than one would think to maintain flight? Just wondering what the flight characteristics of these things are like.

Correction: My Sky Surfer's parachute is 48"x16" and the motor is said to be a Mabuchi 370. I do know it's geared w/ a 9" prop. I'm starting to suspect that this airfoil design requires 7-8 mph foward speed to fly regardless of size. And that wingspan increases w/ weight of payload. If not, someone jump in!
