Well I received my Hornet 2 a couple of days ago and finished the assembly and set up this morning. Every thing seemed to be functioning properly so I decided to take it up in a hover to check it out. Spooled up nicely and had a decent headspeed (by sound) and so I applied pitch. Just as it was getting a little light on the skids it jumped up in the air about 3 feet, pirouetted violently counter clockwise and then straight back down. Since it landed hard I checked it out and decided to try it again. Again just as it was about to leave the ground, jumps straight up, pirouettes violently, and slams to the ground. This time it broke a skid. Any ideas or has anyone else experienced this? By the way I do fly nitro helis so i have some setup and flight experience. Not a beginner at this point, except with the Hornet.

Sounds like your receiver is getting hit. What antenna? Where is your equipment located?

No I don't think the radio equipment is the problem. I am flying at my house just like I do with the other helis. Same tx and same channel.

I don't mean from an outside source. Probably motor or ESC. is too close to the receiver, antenna or gyro.

Is the gyro correcting in the right direction? I know it sounds like a newbie issue but it's easy to make a mistake.

I located the radio equipment just like it was shown in the instructions. And its all MS equipment so it should be compatible. I will certainly go back thru it and check everything that has been suggested. Could be that something is sticking as someone mentioned. That would make sense as the gyro probably couldnt handle the kind of torque generated by the heli leaping into the air the way it does. I am able to move the tail a little right/left just before the heli jumps up.

I'd say "check the gyro".

What can cause a heli to go (straight) up?

More power
More pitch

If so, the tail corrects the wrong way hard since the more
the heli pirouettes the more it tries to ... it needs less
power thus there's more power available for
the main rotor (heli goes up, pirouettes).

Now the esc cuts power to keep rpm steady,
you react and slam pitch down, and voilà.

A glitch imho would make the heli go berserk, not straigt up then down.

Since you're experienced, give it a try without the gyro.
When up to speed (still on the ground) you should be
able to check whether the servo is going the right way,
if your setup is within trim range, you could try and hover some.

I'd only mount a makeshift training gear first

Hello MS HORNET 2 PROBLEMS

Hello,

I have had the same problem using my GWS 6 channel receiver.
What i did to fix it was to wrap the receiver in aluminum foil fixed any stray RF i was getting.

Problem Repaired.
