Hello i have resent received a fun tiger fun fly and i was wondering, what is the proper way to set it up to hover easier (if there is such a thing). it is a little nose heavy. I also heard that you need to setup engine thrust with down and right thrust. is this true? any help would be nice thx.

First off you need it to be as tail heavy as you can stand to fly it. Then you will need plenty of power and a low pitch prop. Then lots and lots of practice...

You might need a little right thrust... and make sure your motor is running rock solid!!! Don't want to flame out in a hover... bad things happen...

IMO, hovering requires less of a rearward CG than most of the 3D maneuvers. It should be a bit tail-heavy, but it doesn't have to be extreme.

The plane needs lots of elevator and rudder throw. The servos should have enough torque and speed. For a 4 lb profile, standard servos are usually fine, mini's may or may not be enough.

You need power. At least a 1.5 to 1 thrust to weight ratio. The higher the power, the easier it is to get out of trouble. Large diameter, low pitch props are the key. On a .46 two stroke, the prop of choice seems to be the APC 11.5x4, although some people use the 12.25x3.75, 12x4, or 11x4 with good success.

Right thrust seems to help. I'm not sure about down thrust.

The last thing you need is several gallons of fuel.


Good luck,

ok, first right thrust, your plane should climb straight on full throttle.
down thrust, it should fly with no difference in pitch at different throttle settings, all pretty standard.
on my Cougar, i've moved the CofG forwards and back, and not noticed a difference.

i used a 10x4 APC prop, not a large one like recommended, it gave me instant response to get out of there, i now use a 11x4 Master because it works better in the hang.

you need lots of practice, you should get to a point where you can let it drift downwind at about 20 feet high keeping it in that hang.
for this you need a perfect bottom end response, so work on this, half a breaths turn on the needle can make the difference, its all about confidence, to this point also use a plane you've had a while, or crashed, once i crunched my pretty Cougar i got better at hanging.

come in to a hover into wind ( 5mph ish is good no more than 10 to start ) low over the patch, forget those "no hanging over the patch" farts, you need to see what the planes doing, its best to do this with the more relaxed fliers around. and in the air alone.

over the next couple of mins work on your hover using the rudder more and more to keep it pointing straight, you should also be getting the nose higher and higher, your not hanging yet, just hovering at a high AOA, you'll find you use the rudder more and ailerons less, your also holding back on the elevator.
after a few mins you'll find your almost vert, depending on the wind that is, its not easy to learn in no wind, you need sommit to push against.

when i was doing this i was really working the throttle, dancing all over, but it kept my fingers learning quick! the other way is set throttle, set sticks and it more or less stays in one place, i think you learn a bit slower this way.

at this point i landed as i was almost dry, i had also now found that my fingers knew what to do, but the plane didn't respond quick enough, oh how the tide turns
i upped my throws but kept the same expo, just to make it respond faster around middle stick.
i took off again, came in low, touched my wheels, stalled, popped up, and held it at 45-50 degrees, a little more up and throttle and i was hanging, yes, as quick as that!
i touched my tail the next flight, once you've got it it snaps.

its all about confidence, knowing the engine wont quit is one biggy, not worrying too much about the plane is another, and last and best, from 20 feet you can seriously damage the plane if you fall out of hang, from 4 feet up, you'll do very little, and thats a big confidence boost.

you can see a video of my Cougar falling out with no damage on my site, the links below.
keep at it, it takes practice, but once got, you'll wonder how you couldn't do it before.

I have a Morris the Knife that was initially setup with 0 thrust. I use an OS46SF with an Ultrathrust muffler and an APC 12.25x3.75 prop. Loads of power and great transition. Hovering was a real problem had to use alot of rudder. I then made some shims out of hardwood and set the engine with 2 deg Rt thrust. WOW big difference. Hovering easy now and ground handling way better. No need for any down thrust. Enjoy, Pete
