GallopingGhost

Ok guys its opinion time. This is based on the logo design used by the company I work for. I thought it would be a flyable shape. The undersized elevator and short tail has me wondering. Should I go with ailerons and elevator or try it with elevons and maybe slave the elevator? Anyone have a clue where the CG should be?

Should fly fine. Flying stab would work better. May be able to cheat a bit and enlarge the stab but I don't think it would be necessary. What does the rudder look like? Make sure you make it big enough or you may get into a dutch roll problem with such a short tail moment arm. Make a 9 or 12 in. balsa or depron glider with the same planform to find the CG. Put a bit of up elevator in it and add nose weight till you get a fast flat glide. CG will be in the same place on a bigger one. Hope this helps. Ain't experimenting fun

Hi Gord,
Thanks for the reply. The vertical fin is about the same size as the under sized stab. Maybe the flat Fuse side will hold its own. Got the radio installed, the CG is about a inch behind the 90 degree area of the leading edge which might be nose heavy but its a start. It has enough power on 7.2 V to more than support (hover) its own weight. Weather permiting thursday might be the day. If it lives I'll work out the bugs and the next one will get more attention and the company Logo. That should trip out the guys at work.

hey looks like a nice plane should fly good. I like your username also.I dont think most will get the full effect of it,Guess you been flying RC for a long time as my fatrher has he started in the 60s.hes told me all about the old systems
good luck on your plane let us know how it flys.

For the CG have a look at

You got me, I've been flying on and off since the 60's. If you don't know what Galloping Ghost is all I can say is you need to see it to believe it.
It flew, it has more thrust pull than I expected and needs lotsa right thrust. I flew it on aileron and elevator first so all the work my left thumb was doing trying to feed in right rudder was a bit wasted. Reflexes are great but they need servos and control sufaces. I now have a basis for changes or perhaps a larger version. I had the thought I should have put rudder on it from the start but no harm done. Besides it fun doing left circles holding right aileron!
Thanks for the CG info fdix!

I'd take the motor and battery out, use weights to find a starting CG and throw it like a chuck glider. Move the CG back or forward until you find the one that will give you a nice glide. If it gets a little bent, just cut another "pretty" one out and mount the motor and go fly.

The right thrust was the ticket. Flys stright and rolls like a ball. It flys like its tail heavy until you get out of the power. Man, this Fan Fold holds up good........so far its a better logo than a model . The CG program is hard to use on a shape like this. Jonnyjetprop and flypaper 2 CG test may be over due.....the airframe is showing a little abuse .

Galloping Ghost:
Went through the GG phase too. Last one I had was the Rand Actuator. We'll let the newbies figure out how they got rudder, elevator, and throttle out of one servo Went to reeds after that.

GallopingGhost

Let give 'em a hint its like servos on Jolt Cola.
Do you remimber the Ace Pulse Proportional magnetic actuators? We need to post a photo of a reeds TX! Now thats something for a newbie to ponder.

I still have a F&M Matador reed trans. and a E. D. single channel trans. Funny part is, the single channel trans. is bigger than the F&M and both are bigger than than the ones we have now. Some of the planes were very small for their age. Built a 12 in span model with an Otarion rcvr. The rcvr was a kit you had to put together. Was about the size of a postage stamp. No I.C.s back then. Actuator was a relay with a brass arm soldered to the movable part. Power was a Cox .010. No throttle control, only rudder. Flew well. They were the do it yourself days

Hey Galloping Gost,
Your user name and post's bring back memories of the early 60's for me.
I flew the Galloping Gost system or pulse. I had a nice little Bipe with the wagging rudder and elevator.

Do you have any vids? Looks like a nice design. Also, have you tried to use a pusher design for it? Your front end looks a lot like my F22 and it's a pusher on elevons.

GallopingGhost

I thought about doing the helmet cam trick but didn't. I expect that first flight would have been worth watching.... Keep in mind this design is from a company logo thus making the nose moment too long for prop in the frt. I expected that and found it true. Pusher or D/F might be the trick. I did the glider CG test and the CG was way to far forward by that. I might work up the funds for another $1.50 in foam for the next version I just finished a Blue foam sorta IFO that may fly or die today. Stay tuned.

I've done the "Oakley Cam" and it worked fine as long as you dont fly too far. I mounted the camera on my Oakley sunglasses via rubberband and put the camcorder in my fanny pack. Keep us posted.

GallopingGhost

Shhhh, don't give up the secret...... ahhh the newbies will never believe it anyway. Come to think of it I'm not sure I would believe it if I didn't know.

protojet1.pdfHere a concept pusher foamie. Drew this up and started a build. I will attach some construction pictures later this week.

Castor

Here are some build pictures of the pusher prototype jet. Let me know what you guys think!!

GG.....Your secret is safe with me.
Castor..... Lookin Good man.

Well here are the build photos of day 3 for this project. I made some headway in putting on the intakes and motor mount. I am working on the details of a removable rear cover to gain access to the radio gear. I haven't decided on what to call this thing (any suggestions) if it flies like i predict, it will scare the *#$& out of me. So maybe i'll call it the scat fighter. Suggestions Please on a name and markings!!
