Status: offline 		Hey, spent the last 2 days trying to fly my Jabo 2 NO LUCK. I can hover the helicopters on FMS by just literally holding the throttle and moving the sticks a little. I dont think I have been able to kepe my heli in the air for more than 5 ecs. I lift the throttle and it flys in all different directions. I cant trim it whilst its in the air, and all my trims besides throttle are centred.

How did you guys learn? I want to be able to fly it in small areas and hover etc.


I dont wanna give up....

Josh

Status: offline 		its tough but if your not able to hold it up long enough to learn what trims need to be adjusted and its a micro heli i would say hold it by the tail boom just behind the frame and in the air give it alittle throttle and feel which way its trying to pull, it should stay neutral if it pulls left then you need to give it alittle right cyclic etc, and make sure the center of gravity is right, otherwise it will just be hard to fly no matter what, you can move the battery around to help center the weight plus you can use alittle of the elevator trim to tweak it in. Just becareful with the blades spinning if you try to hold it to trim it out.

Status: offline 		Its really annoying because whenever I crash it, the swash plate thing comes away from the bearings and I need to adjust it.... Its wierd when you hold it by the teail, because if your not holding it directly straight, it pulls away. Also, you cannot adjust where the battery is....

Also, should the bars of the balance bar be at a slight angle, form the centre, maybe 3-4 degrees.

Status: offline 		The paddles should be equally flat and horizontal with the flybar when the swashplate is level - ie, both in the same plane.

I feel your pain. I experienced much the same. Now I can fly my Walkera 4 above my bed quite happily. I land it on my car roof and fly it all over my front yard.

Do this on FMS.

Go to the Winter Heli (I think that's the one) set where you start on the numbers. Fly from 1 to 2. Land. Front 2 to 3. Land etc. Do this until you get to 9.

When you can do this, you can control the Heli in a wide open space.

Then set the wind to 3ms with 3ms gusts. Now do the same level. When you can do this without crashing, you are ready to fly in smaller spaces, say, 6m x 6m.

Wobbles are caused by imbalance in the rotors and too low a head speed,

Regards
David

Status: offline 		how is the blade tracking on that one that is vibrating alot? if the blades are not tracking right it will shake violently.

I know they are probably fp heli's but even those can have the blades out of track.

Status: offline 		Sorry, I dont know what u mean,

Should I take it too a large filed and fly it, as I have very little space.

its just really p**sing me off that I cant fly it, I think its gunna break before I fly it etc.... and everytime I land badly iI have to put the swash plate back on the bearings and realight the back blade,,,....,,, shoudl I use the traning gear?

How long did it take u, because I can fly the aerohawk on fms

Status: offline 		i could easily fly the helis on fms but could barely hover my honey bee 2 tail in, The only thing fms is going to teach you is what ways to move the sticks in certain situations. Dont just try to fly it around in the simulator try to make it do exactly what you want it to, like go from point to point turn 90 degrees and go to the next point. I often do this in reflex xtr simulator i go indoors and i try to fly it slowly along the walls first with the nose facing forward, then i try to do the same thing again but i fly it sideways around the edge of the walls. I wasnt learning to much when i just pushed the sticks around to make it fly all over, im not saying this is what you do , just trying to give some advice to helping the learning curve involved.

as far as the training gear i would use it, it saved me alot of broken parts though it wont save you from everything, and its actually harder to fly the heli once its in the air with the training gear on it. however since its vibrating so much i would try checking to make sure your blades are balanced, and that they are tracking correctly, also make sure tha main gear shaft is not bent.

Status: offline 		When it spins, it looks like the large gear is slightly bent, but I cant see that causing a problem...

Also, whats the tracking... I have LOADS of spare parts, besides main gears so maybe I cna change some things....

Also, I tried it without the training kit,,, argh snapped something.

Is it normal that when u jam the throttle on to get it in the air, it shoots to one side, I have never ever ever managed to get it go straight up for more than 2 secs before it veers to one side. I cant understand how people get it to hover straight, they must have fast fingers.

I cant manage to keep it in the air, just impossible

Status: offline 		Josh,

Helicopters rarely if ever take off straight into the air. The helicopter will always naturally move to the left due to rotor torque and the tail rotor countering that torque. With the exception of your trims being off, the only way to take off straight is to learn how to fight the helicopters movements while on the ground. You will almost always require some right cyclic to keep the heli from skittering off to the left during take off.

If the heli continues to veer to the left even once airborne (and out of ground effect) then mess around with your trims untill the heli stays in a general area without heavy stick movement. Even airborne the helicopter will still drift to the left, however, it should happen slowly (assuming you're in a steady hover to begin with). If you constantly need to give heavy right cyclic to keep the heli stationary then you've got a trim problem

If there's anything i've noticed about FP birds, it's that they require enourmous ammounts of attention. You need to constantly keep your eye on the bird and watching and anticipating how it's going to move and react next. Typically speaking, the stick movements of your controller should be directly relative to the ammount the servos are moving on your heli. In other words, it takes very little stick movement to get the heli to move in any given direction. Over-correcting will end up in a crash. Quick, small stick movements in small ammounts of time work better than big stick movements over larger ammounts of time.

Hope i've been of some help, as i've gone through the same thing you have learning to fly a fixed pitch heli, but after awhile you just "get it" and then flying becomes so much easier. I can hover in a tiny space in my room now without much problem using a hybrid GWS Dragonfly/Walkera #4 Dragonfly heli.

Status: offline 		If its shaking violently, most likely one of two things is wrong. Either the blades are out of track, or the main shaft is bent. If the main shaft is bent....even just a few thousandths, it will shake like crazy.

Also use the training gear. Make sure that the training gear is at least as wide as the rotor disk. The training gear will save you alot of damage, even if you do tip it over. They tend to absorb alot of the shock.

Since your having difficulties keeping the heli stable in the air. Try just getting it light on the skids. And let it skid around on the ground until you get used to how it moves. If your radio has expo in it, try putting some expo on your cyclic. It will tone down the cyclic response to make it not so touchy.

Status: offline 		I had similar problems when I first started out. I had the rotofly. I found if you move the blades about 1/2 inch forward it would get rid of that wobble. (line the trailing edge of the blades with the head screws). Also it would pull left uncontrollably. You have to jerk it off the ground about 2 feet to even have a chance. Also it won't fly outside. Even when you think it calm the slightest breeze will bring disaster.

Status: offline 		As I said, I think my main gear may be a little bent...

Will the shaking stop me from being able to fly it, because sometimes it shakes, and sometimes it doesnt... So I think tis just I need the main blades completely straight on the swash plate. Its driving me nuts, I have a fairly large yard and I still dont have enough space, Im scared to take it too high because I lose control and crash... its ABSOLUTELY nothing like fms.
