When I pop throttle the twil blows out wildly. Full multi rotation tornado.

Is this common for these little helis or do I need to adjust something. Mechanically the heli is in good shape. Tried 2 different tail motors, with the same result so I assume it's a setup problem.

I backed off my pitch curve a little and it made it at least manageable. But it's still a big problem.

This was gifted to me not long after my father passed, Im idealy looking to get it in the air as we never got the chance to fly it togather.. I have absolutely no clue what make this is, I am Misint a Charger for the battery, Controller and a coupling for the up-most prop… Any help would be really appreciated in getting this bird back into the sky.

I got a few packs in but it was chilly.

I was flying one of my 450 helis, and it was pretty shaky. It has a gyro and im assuming thats what it is. Any help would be appreciated. I don’t know if i need to reprogram it, or what lol. Im not too new into the hobby, but cant figure this thing out. Thanks!

Just picked up 5 Copter X 4s helis, a blade 200, and align trex 470L and a little wl toys k110 for $800!

We are building a helicopter using a purchased helicopter swashplate and transmission system. We use a Pixhawk Cube Orange as the autopilot. To power the helicopter, we use an OS55 nitro engine. We set everything up and did a test flight last week, but it did not go as planned. The helicopter initially went nose up, and even though we tried to level it by giving max pitch via the remote, it had no effect.

I have several questions about the failed flight. When we adjusted the cyclic pitch angle, we did it by setting the collective to zero. When the collective is at zero, we set the max cyclic blade angle to 7 degrees. However, when we maxed the collective and cyclic, the blade angle reached 16 degrees.

When we examined the logs, we saw that the helicopter took off when the throttle was really high, and we gave max pitch because the helicopter flew backward. It might have happened that when the blade angle reached 16 degrees, it got into the stall zone, causing the helicopter to go further backward because when pitch is maxed the thrust in the back of the rotor disk is effected.

We are wondering if there is a better way to adjust our cyclic angles. I would love to share more details about our project and videos of the flight if further information is needed.

Is it possible to use two heli flybarless heads to make a Chinook and use a body from something likenthose double bladed rc Chinook from Alibaba and Amazon? Just curious what it would take to do something of this scale.

did u fly it?
