Hi folks
I've just purchased 3D Magic fun fly, and I've read that you can do just about anything with it but can you actualy knife edge this little beast? I'm setting it for 3D and will use OS46fx with APC 12.25x3.75. All comments about this plane are appreciated.

The modeltech? You betcha. Be ready on the aileron and elevator and make sure you have lots of rudder throw and it can be done!

Cut the tips off and it will probably do it even better...
It will roll faster too

I dont recon it can be done. There just isnt enough side area, no matter how much rudder you got. And the coupling is just ludercrus!

Tips on plane, dont get that engine for it! get an OS 32 and a 10x4 or 10x5 prop! soooo much better

Dude, I've done it with that exact setup (46FX and 12.25x3.75). Was flying it for a buddy. Fun airplanes.

I cant get mine to do it ether. mount your rudder and elevator servo in the tail. it flys better tail heavey. Its not a good fast flying plane but slow stuff is graet. I was flying in the wind one day and hade to hold the plane on the ground with my hand. hovers are ok a little unstable but that will make you better at hovering. when i fly my DP extra I can hover with out thinking about it. The magic is vary fun plane to fly around. I have a 40 fx at 5000ft elev and has good power for hovering. flat spins are cool whin you pull out at 10 ft off the ground.

Try a cougar for hovering. Welsh 3D of 3DRC.info did a TR with one, 8 rolls with one hand on the tx! Its so easy to hover the thing. Mine is just brilliant, just gone around to see my friend and he gets 80 deg of rudder throw, it still wont do KE.

yes the coupling is bad ian , but have you tried it, no side area is a disadvantage but does not make it impossible.

get it going fast enough and it will do it no problem, cougars knife edge particularly well ian!!!



its not what they are meant for though, and the magics fin might fall off, they are weak!!

I made the first flight on my buddys. He has the same setup up as you. He runs 30% nitro though.
It would knife edge but was a handfull. A lot of ELEV and AILE are required. It could be done better with a little practice and/or mixing.

Thanks guys for your comments. Well... some say it can be done , some say it can't. I know a lot of people including myself in order to stay in KE tilt the wings from vertical few degrees one or the other way and with a little elevator input you can control altitude, so you don't fall out of it. It's a little cheat but it works well. I believe you should be able to do that with this little beast. The only problem is that some planes need more input than others (depending on CG, power plant, shape and amount of rudder deflection available). The planes that don't KE well would probably require tilt that nears 45 degrees but would you still call it Knife Edge?

I have lots and lotsa control throws on all surfaces and a rossi 45 with a 12.25x3.75 prop and it won't knife edge for shizzle. It might fake it for a few seconds while I fight it but it loses altitude.

Knife edge is a weak point on the Magic FunFly. It is possible especially if the wind is right to help you but I doubt it will be a regularly enjoyable part of your flying with this plane. However, there is so much else that you can do you probably won't miss it.

Don't try to tell me it won't cause I've done it!

Very unstable but I've done it one a couple of occasions.Not it's strong suit for sure!

Yes, tried a few time, did it to low once and it just flipped it inverted, will try again tho next time, hopefully Saturday if i can find a 10x5 prop

10*5 prop!!!!!!What motor are you using???That ,to me, is a speed prop.Use a 12.75*3.75.At least a 11*4.This plane is meant to fly sloooooowww...Try doing some computer mixing this plane is so fun in that aspect.Ele-flp,rud-ele(for knife edge)Super fun plane!!

Do have all the mixing on possible, spoilerns, flapperons the bizness! Im using a irvine 36. Now ive used a small engineon a light wight funfly wi wouldnt ever go above a 39 (irvine). Thats why i always say forget the 46s as theese just add weigh, use a 32-39! i got a 2.5:1 power to weight ratio on my cougar!

Full Elevator/Flap mix.This will make the plane float like noth'n else!!

The Magic can knife edge, but it is difficult because it is short coupled and does not have that much side area. You will not be dissapointed at all with the Magic. With the right setup you can get it to do everything in the book.

magic will do a very sloppy knife edge if you use the engine to your advantge enter a hover and let it slide over alittle to one side and work the throttle to help keep it up, its more of a tail slide than a knife edge oo btw that 12.25 x 3.75 is not the best prop i ve found my .46s allow for good 3d and better throttle response using APC 11.5x4 but this is just my .02 cents btw the magic flat spins really well and is a hovering machine!!!! perfect 3d

You are right guys I found I can do it but it's a handful. I've got to work aileron and elevator a lot. Now, I should really start a new thread but since my other question directly relates to the same plane I'll stay in this one. The real reason why I bought this plane is , I want to learn to TR. I've been practising now with my new magic for 3days in a row but I can only get as far as 90 degrees of rotation and then I loose it. Twice I actualy managed 180 degrees but that I think was more luck than skill. Dear fellow TR experts what should be the next thing I should concentrate on. Are there any expected tendencies ? Talking about tendencies , once I get it into the sweet spot I feel that in order to keep it vertical I really need to work left rudder rather than right one. Seems to be complete opposite from what I've read so far. Are there any tricks perhaps I should be aware of? Maybe I have too much expectation from myself at this moment but I think any good hint can speed up the learning curve.

well said, and not a 45 degree banking side slip, i mean a full on knife edge. SPEED IS THE KEY!! (the model, not you[&:]!)

If it falls off to the right, and you need to hold left, mabey you have too much right thrust?

Anyway, when the belly is towards you, push the rudder in the direction that the plane falls out. In other words, with the belly towards you and the plane falling out to the right, push the rudder to the right also. Just a little trick that helps. My $0.02

thanks 3d-kid330 I think you are right with too much right thrust. I will try no right thrust at all and see what happens. That belly trick is good too quite easy to remember
