I'm wanting an ARF 40 size plane that will flat spin like a top. Any one know the plane to get? Rather not be a bipe.

You can not beat a profile for flat spin moves. The new Mojo ARF will do upright and inverted flat spins with ease and if you play with the throttle a bit, you can get it into a inverted climbing flat spin, those are cool.

Ok, I'm new to RC planes. When you say flat spin, is it just like Mavricks F-14 in Topgun when he gets jet washed and spins uncontrollably towards the deck? Also, how does one enter into a flat spin (full rudder)? I know in our F-18's our pilots have an anti-spin recover switch, just wondering if its the same thing. Thanks,

Kyle

anyone?

Pretty much although I don't know much about it in jets. Basically the plane is in a "flat spin", the plane is falling in a flat stall with no forward motion in a rotation.
This is a manuever thats performed by using full rudder, full elevator (up or down depending on inverted or upright) with a little aileron to flatten the wings.
Throttle is used to bring the nose up and keep it from dropping into a dive.

Certain planes can exit and enter these fairly easily. Some planes (those with a short tail moment) will almost never come out of a flat spin.

That's right Sarge, It's the same maneuver that killed the Goose in Top Gun.

Only most of our planes can recover from it... hopefully!

If you'd like to see it done, look at this review I did a while back, and check out the video

Awesome review and I enjoyed the video.

Thanks

The profiles are the way to go if you want to flat spin like a top. My 25 size taco spins nice and flat. Look at the MOJO that was already talked about, the extreme flight edge, ohiomodelproducts, and the top cap from morrishobbies.com

Carl Goldbergs Matrix 40 spins so flat its not funny. Great little plane.

The Jupiter and the Ready from Falcon Trading also do Great flat spins, both upright and inverted. The neat thing about both of these is that all you have to do is let go of the sticks and they right themselves pretty much ( with enough altitude ) something a lot of planes won't do even when forced. They are both 40 size ( I use 46's ) and really fly great no mater what you do with them. You can see them at www falcon-trading.com. ENJOY !!! RED

Errrrr, thanks for the response. That was a nice video!

If you prefer something other than profiles or "fun-fly" planes, believe or not, a simple Sig 4 Star .40 will flat spin VERY well, even with the stock CG. You will have to go to near max throws on the ailerons, rudder, and elevatore, but with mine, it is very easy. First, enter a conventional upright spin, with trhottle at idle. Then, once the spin is established, slowly start to cross the aileron, as you bring the throttle up towards full at the same time. By the time the aileron is fully crossed, you should be at full throttle, and the thing should be in such a flat spin it looks like a Canadian Maple leaf falling slowly from the sky. You can try just throttling back and releasing the stick to exit, but I have had better luck by FIRST un-crossing the aileron (aileron moved back to the same position as the rudder) until the nose drops and the plane resumes a conventional spin. Then all you have to do is let go of the sticks, and it should pop right out into a nose down dive.

Lee,

Can you describe a "conventional upright spin". This isn't a smart ..s question, it is a basic flying maneuver I have never quite understood properly and how it is done.

MAGIC FUN FLY from modeltech. It is UNBELIEVABLE in a flatspin, inverted or upright. There are a couple of my vids on flyingcirkus.com. Fantastic plane!! Here is a vid with a flat spin at the begining [link=http://media.putfile.com/throwin-the-magic-around]magic video[/link]

Another cheap ARF to consider that flat spins very well is the Hangar 9 Twist.

I have the twist as well as the magic, and for flat spins you can't beat the magic.

Chuck, for a "conventional" upright spin you want to start with plenty of altitude and then with the plane staright and level, bring the power to idle and as the speed bleeds off, gradually bring the nose up to keep the plane from loosing altitude. Eventually the plane should stall (quit flying) as you come back to the stop with full up elevator. With most planes, as you continue to hold full up elevator, if you also add full rudder (either direction, but you will find that some planes spin better one direction of the other...just experiment to see), and the plane should enter a spin where it looses altitude rapidly while rotating rapidly in the direction of the rudder you input. Many times you may find that it is also necessary to add aileron in the same direction of the rudder to produce an even tighter spin (the aileron input will help keep one half of the wing stalled...which must happen to keep the plane in a spin). Sometimes a little added throttle may increase the rate of rotation in the spin, but in other cases, increased throttle may actually pull the plane out of the spin into a "spiral dive". I should note here that some planes (especially many "stable" trainers) really won't spin well. You will just have to try your and see.

Anyway, once the plane is in a spin, MOST will recover simply by releasing all controls and allowing them to return to neutral (elevator, rudder, and ailerons), the throttle should also be returned to idle. At this point the plane should recover (stop rotating) and just drop it's nose until it regains flight speed. At that point, the nose can gently be raise dback up to level as the throttle is slowly advanced back to cruise setting. Hoever, if the plane continues to spin after all controls are neutralized, you need to stay calm and try applying opposite rudder (from the direction you input to start the spin), and possibly some down elevator...both just until the rotations stop. The hardest part is to relax and wait a second or two after the rotations stop (to allow the plane to build up flying speed again) before GENTLY applying up elevator to pull the plane out of it's dive. Many planes will start to spin AGAIN if the panicked pilot yanks too much up elevator too soon after starting the spin recovery.

Hope that helps...

I second on the Twist. Mine does incredible flat spins. I can got it spinning, and by adding throttle get it to stop falling and start climbing again, while still in a flat spin. Great airplane, only $99. If you get one, add some markings to the bottom, otherwise it's very difficult to tell which way it's pointing when it's in the air.

This may be tyoical, however, I'd like to add that It can be accomplished with no rudder at all. I have a depron F-18 that I can spin and it looks just like the F-14 in top gun and It has no working rudder. The throw on the elevator and ailerons is what makes the differance on this airplane. It is so predictable that I can come out at any heading I choose. I love this plane.
