There are a number of small planes ( and helis ) available for indoor flying . The Night Vapor is probably the best one , it's AUW is 14 grams and it's top speed is about the same as walking . For indoors I've also made an RC blimp , hovercraft , tricopter , etc.
Here's a home made plane flying in a church sanctuary

![]() Rudder? We don't use no rudder. We don't play with no STEEENKING rudder. ![]() Oh. Rudder. Yeah, I can try that. ![]() Think of it this way... after I get done, you are going to have an encyclopedic treatise on ALL the mistakes a beginning doofus can make with the SUE. Seems like nobody else was making them, so I'm going to go through them all !!!! I'll try to get the Missus out tomorrow to film the debacle... the debut flight. Ad Astra... even if we are going to have to dig our way out through the center of the Earth and past China one nose divot at a time !!!! |

Dan now at least you know the full throttle atlas booster on from a dead stop launch method isn't working so well huh? Sounds like torque roll to me. There is something wrong when I can toss a plane farther than I make it from a powered start that's when I toss it first to give it momentum then add the throttle. There is a good youtube video about launching rc planes check it out

When you get it launched and turned one good trick to remember is move the stick towards the low wing when the plane is coming towards you to level it out. Left and right thinking is kind of slow when you are nervous that way you don't move the stick the wrong way trying to correct direction. I've heard of people that crash that way a lot.
Not old pros like me though |

I second Al's opinion of the prop maybe not straight causing the left turn. Use the rudder man get on the stick and fly it at least to a good landing and check out all the trims. I noticed with stick mounts is when you tighten the screw from the mount to the stick it will tend to twist it so mount the motor first to the stick and go by the motor and prop being straight not the stick. Or the rudder trim isn't centered

![]() The prop had been misaligned by 0.136 " Yow... Well, since drastic surgery was called for, I simply sliced the front of the wings off at the 10" mark, leaving 4" of solid and undamaged foam in front of the prop slot. I also cut the front 5" of the fuselage off. This left me with a 5" section to build from. I freed the front of the stick, leaving the last 1/2" still attached. I then reattached new wing fronts using hot melt butt joints and tape facing over the joint, and then a new nose on the fuselage using a 1" overlap scarf joint to the old fuselage. Everything was aligned, jigged, and then hot melted into place.The motor stick was then aligned so that the prop is now even to within +/- 0.015" on each side. I hot melt glued it and allowed it to cool before removing the alignment jig. I seriously hope I don't have to work to +/- thousandths... Next, I soldered the plug from a sacrificial Y harness to the ESC control line, and heat shrunk 1/16'th tube over each line. Tested all the controls, and she's ready for balance testing, trim testing, and a launch with less than full throttle. ![]() I also re-glued the mast-base for the antenna on my transmitter. While I was at the hobby shop this weekend, I remember seeing a number of those and thinking "what kind of doofus breaks his antenna and needs to replace it?" At least one answer is a doofus who sets the transmitter on the edge of the table and then bangs the wing of a NEKKID SE into it... ![]() So, whats the name of a famous actress who had a nose job ? I am thinking of naming this incarnation of the plane after her ![]() Ad Astra ? |

![]() When doing a few static test stand run-ups of the motor... I noticed that it moved !!! It could twist on the balsa shaft ! I could wiggle the prop tips back and forth by 0.077 inches by applying a rather small amount of force (20 to 50 grams? I didn't measure it.) Oh Oh. I had meticulously sanded the balsa beam down to get a tight press fit and attached it with a screw. But apparently the stresses on the system had strained the balsa past it's crush strength. So, a little work with some CA... and hopefully it will be solid tomorrow. If not... maybe some epoxy and a syringe. ![]() Thinking about it... it seems that perhaps a stronger material is indicated for the motor mounting stick. I tried finding good numbers for compression strength perpendicular to the grain for balsa, basswood, fir, etc., but I didn't find anything in a short search. SO... I took 3/32 balsa and 3/32 basswood, stacked them, trimmed them to the same dimensions side to side, and put the sandwich in my soldering vice. A little turn on the crank and I observed that the balsa crushes long before the basswood does. Hm... ![]() And it all seemed so EASY... *laugh* |

Significant improvement
HEY...
There has been significant improvement ![]() Today's technical glitch was new - peeling the battery off of the frame. So I get everything together and I tell the Missus that I'm off to go flying. Good luck !!! Don't you wish me good skills ? No. You need lots of luck. Frazzle frazz gargle barg If we hadn't been married for 30 years and if she didn't know where the bodies were buried, I might reconsider proposing to her. Out to the aerodrome. Flight 1: Test control surfaces, send a prayer to St Daedalus (the one who didn't crash), run the power up to 60% instead of "Atlas Booster"... give her a toss and... it heels over. I apply rudder. WOW. I can sort of correct. It needs more altitude and remembering the words "control it with rudder and throttle" I pull back on the throttle just like I would pull back on the elevators. Of course, thats the wrong way However, the NEKKID SUE just swooshes into the grass and stops. HOLY POOPIES !!! Apparently it's NOT a rule of fyzzix that my planes have to land approximately perpendicular to the earth nose first. I step it off... about 110 feet. WOW. However, the velcro holding battery has peeled the paper off... Okay, back to the aviation repair facility, also known as the kitchen table. A little tape, a new piece of velcro, and an excited report to the wife... "It's only minor repairs!!!!" .. Cheers all around. On the way out the door "Good luck !!!" I decide not to reply. Flight 2: My brother decides to join me... great, another peanut gallery. ![]() Test the controls, run it up to 60%, and give it a heave. WOW, it's still banking to the left, but this here rudder thing can handle that. Of course, that slows it down and so it loses altitude. I try the throttle again, and once again... make the backwards choice... However, it whooshes into the grass at over 100 yards away. WOW. The recovery team reports that the plane is fine, but the new velcro and tape have sort of done it's thing - they held firm to the paper and foam beneath it. The battery is laying next to the plane, firmly holding onto an egg shaped bit of foam. Back to the repair facility. I think... all my electronics are on the left of the fuselage. The plane constantly banks to the left. HMMMM. So, I cut a small pass through port in the fuse, and mount the battery on the right side... I also put it a lot lower, down near the keel. This time I sneak out without a report to the commanding officer. Flight 3: My brother and his dog follow. He's out of work, so he doesn't have anything better to do than to hassle me on my birthday. His question: "Do you think you can manage a turn this time?" ... annoys me... except... it's a fair question. ![]() Pre flight check, make sure the crowd is behind me... LAUNCH. Wobble wobble, I manage straight and level flight. I go wild !!! Then I decide to show my brother I can turn it. Using rudder and elevators I manage to turn it around. It's coming at us... Okay, I can turn it. Meanwhile his dog has decided she doesn't like this thing, and so she starts to move away from us. I turn the plane, and it accidentally turns towards the dog. She moves more, and I turn more. It's like there is a compass needle to the dog.Are you trying to hit my dog? ![]() I don't have that much control! ![]() Fortunately I manage to turn it again. I lose control shortly after that and it comes down softly in a big brush. My brother says "That was an okay landing. Nothing is broken." My comment - "That's a blackberry bush." It's in the middle of a 20' diameter blackberry thicket. I go get the branch cutters. My brother decides I'm boring and goes away.20 minutes later I'm all scratched up, but NEKKID SUE is okay. Nobody told me that this hobby would involve BLOOD. Between a knuckle encountering a spinning prop, a couple of finger sticks with an x-acto, a few small burns from hot melt, and this... I'm beginning to think that it's safer to work with explosives. Flights 4 through ?? Okay, the rest of the flights weren't so "entertaining". I resolved to stick with simple turns, climbs, descents, etc. I actually managed to land her once. I never got a "long" flight in... my turns still suck big time... but, I managed to actually sort of fly the thing. Sorta. Kinda. Well, I didn't completely suck. ![]() The last flight of the day was a little nose-ish... and that caused a sudden shift in half the electronics. Apparently the connection of the ground cable to the ESC had enough abuse for the day. The black wire came out from under the heat shrink and is just hanging there in space. I hope it's just a matter of removing the heat shrink around the ESC and resoldering the wire to the pad or through hole... I don't see any evidence of phenolic breakage (yet). SO... I will give you the same report that I gave to She Who Must Be Obeyed: I have significantly reduced my suck factor !!! At this rate, I might even rate as a really bad pilot by summer 2013. Too bad the world ends on Dec 21'st of this year. Ad Astra... |

Very entertaining.
Congrats is in order. Yes, believe it or not, people do learn how to fly. Sounds to me like the backwards thing is plaguing you though. Remember, when the plane flies towards you, the controls become backwards. One tip you might try is to turn your body away from the plane as it flies towards you and look at it over your shoulder. That helps with the backwards thing until you get used to it. What I use is a tip I received from good ole Pat Tritle. He said when it's coming towards you, just point the stick towards the down wing. What that means is, to maintain level flight, point your aileron (or rudder) stick towards the wing that is lower. Now, this weird paper airplane design, I'm really not so sure is the best thing to learn on. SURE it's cheap. But there are other planes that really are so much better for the beginner. I still feel that what you need is good old fashioned wings and tail, preferrably a high wing or a powered glider. But keep up the good work. And remember, practice really does make perfect. |
