3 dollar foam space shuttle

Any chance, converting this to RC. It is a space shuttle epp foam glider with catapult launcher. The stabilizer is made out of depron. I got it from Micheal's arts and crafts

I don't know anything about fans, but there is 2.4 inches of space wide and 2 inches tall at the end of the plane. it could be easily enlarged though. The wing span is only 10 inches though. Will that work? Forgot to mention, wing is an airfoil from how I see it.

If there isn't any fans small enough I am going to mount a cooler fan on a 280 motor. I heard the fans are powerful. I am going to try free flight first. What would the center of gravity be though. Where to put the battery? Thanks.

cool project! imo, this just begs for an ips direct drive with a small prop, setup as a pusher, elevons, and mount the battery up front.

how big is it? dunno about strapping a fan unit...

The plane's length is 12 inches and wing span is 10 inches. It may be small but it glides very well, and very high. It is an airfoil also so that makes it even better. So, what is better a fan or a propeller?

At 10" WS there are no more than 35 sq. " to work with. That is 1/4 sq ftoot. A one ounce model is 4 oz/ft, a 2 ounce model is 8 oz/ft. That doesn't give you must room to work with. Want does the foamy weigh out of the bag?

ps. Is it solid foam or hollow. Can you show us the bottom?

Another Idea would be to find one of those Foam airliners and Piggy back it up a ways and then Drop it. Have Someone else Glide it back to earth for you.

holy smokes, that's small! then, i'd say definitely nothing more than an ips direct drive and super micro gear on everything. a fan looks cool, but on a wing this small, it may be just dead weight. generally, ounce per ounce, a prop outdrives a fan unit, in our e-hobby.

Hi.

I was looking for a plane like that a few years ago when I played with water rockets.

Put radio gear in it, build a water rocket from a PET bottle and a launcher (Gardena connector or cable tie launcher), hook the glider to the rocket and you have a semi-scale space shuttle.
Flight time is a drawback, just a few seconds...

You have any plans for that water launcher you're talking about ?

Or a site with plans ?

Thanks !

Find an electric 747 for the launch bird. Make a scale tailcone like Enterprise used in glide testing. Install a 3 channel Rx with those 4 gram servos. Launch at 150 feet in no wind conditions.

You are not going to be able to see this bird at any higher altitude and any drive system will make its flight speed a blur. It has not the wing area for its profile. Drag will prevail.

i have one of those and i made the bay doors open so i could put the radio gear in the cargo bay and i found that it needed some reforming on the TE of the wing to fly level and not try to pull up and stall (as mine tryed to every time) i figured on using a rffs-100 and the 2 cell mod with a gasparin gear drive a 3.2:1 it should work.

Thanks for the suggestions,
Well, the plane is full not hollow, too answer you question mike, and the bottom just goes along with the shape. Since it is epp it might be a little more heavy. I was thinking of puting a pager motor with a very small three blade prop at the front of the plane and try like a free flight test with just the thrust from the motor and propeller and small battery. If it works i''l maybe add some rc to it.

Then if that doesn't work I will just do like a piggy back type thing and fly my almost(not yet)electric rc converted, 5 dollar, 4 ft 1/2 wing span, Great planes sailplane(almost exact like the walmart one but very strong yet light epp) that I also got from Micheal's arts and crafts. The way i am going to trigger the shuttle is by doing a rubber band type thing to the sailplane and adding a one channel micro car part to release the trigger. If all comes well, I will post a video. Or maybe a crash if that's interesting.
