Chinook

I`ve had great success with my electric conversion , I have never altered the electronics from the factory setup for Futaba the only problem I have encountered is it kicks up when you stop from a fast forward or backward flight this could probably be sorted with the controller but you know it`s coming so its quite easy to control

Hi guys,

I see there starts do be some Chinook out there now. That's great

I've come to a state where the machine runs quite fine, but I'd like to refine a little the electronic setup to see if I can get it more stable. Can you tell me what are your Gyro Gains for the different axis ? So I could see the tendancies from your setups and not go in the wrong direction

Thanks !

I am also trying to set up a CH-47 I just purchased. I tried to fly it a couple of times and it was pretty squirrely. I have read the posts on this thread and am going to up my ATV's and drop the gyro sensitivity on the elevator since it wants to buck up and down. I too would like to know what other things I need to do. My gyro is attached with foam rubber like mentioned earlier.

Well after reading this thread I found that my elevator and yaw axis on my gyro were backwards like others talked about. After fixing these two items the heli now hovers very stable. I can probably still do some fine tuning since the tail still drifts slightly to the right but other than that it flys great. This thread was a big help. Thanks

Glad I wasn't the only one that had gyros wired reversed!!! It cost me a set of rotor blades the first time I tried to hover using the Hirobo recomended settings.

Skids are for kids!

After reading the posts I thought there is no way my manual has the setting backwards but sure enough I checked and they were. I scraped some covering off of my blades on my first attempt to hover with the setting reversed. I am having a problem now with the blades coming out of sync with each other. The belt feels pretty darn tight but I don't know could it be not tight enough? Almost caused a huge crash.

The belt has to be very tight ------ very very tight.if you turn the heads slowly you should be able to feel every tooth on the belt , also before you put the blades on run it up to speed to equalise the belt tension .

Good info. Thanks so much. Its running like a dream now. Even got into forward flight for the first time today. Really have it flying stable now. Even in 10-15mph wind. You could notice the effects of the wind but it was controllable.
