Use HH for hovering, yaw rate's for forward flight.

that's what i figured, just never heard anyone say. i think i got the tail spinning fixed but when i tried to hover today, it just tried to go forward on me really bad. so i adjusted the elevator arm a little bit then i had to leave for work so i didn't get to try it. maybe i'll get it up in a good hover tomorrow.

Not entirely true. The gyro I have on mine is only a rate gyro, no Heading Hold. Rate mode should hover just fine if you've set up the linkages well. Heading Hold comes more into play when dealing with situations such as crosswinds, sideways or reverse flight. In those situations, the HH will give additional corrective input to maintain heading whereas rate will only moderately resist the external forces. HH will help hold your tail in a hover if your linkages aren't true, but will also mask those issues as well.

i hover fairly well in both modes, but the HH is much easier due to the wind here.

Cool.. just didn't want you to have the impression of "I can't get this thing to sit still in Rate mode, but HH works so it must be fine"

I prefer to stay in HH mode for all flying. With FF you just need to use rudder input to produce a neat turn as the tail wont follow automatically. I only use rate mode for adjusting the mechanical linkages during setup. This is probably filed under "personal preference!"

(And at the moment I'm flying a GY240 on my Shogun so I don't have an option for inflight switching- I used to have a MS-044 which does have remote mode and gain switching, but even with that I decided I prefer to stay in HH all the time.)

CrashTestDummy,

Thanks for throwing that in. Sometimes you think you're doing such a great job explaining something and you still end up leaving out a critical piece! It sounds like Blue has it working in Yaw Rate mode OK on his own though.

yeah, i got it working fairly well. i got her hovering today and a gust of wind(30kts or so) came along so i sat her down and she then flipped over. ouch! bent the bar between the main grips (which i was able to straighten) and bent the main shaft.

thank goodness i have an extra thanks to smokin. you rock man!!! thanks again for the parts. now i just have to pull the rotor head apart and fix it.

Blue,

The spindle shaft you straightened is almost impossible to truly get straight. If when you put her back together you find that you cannot get the blades tracking right, this is most likely going to be the cause. Don't ask me how I know this!

I use a small lathe to straighten shafts,,,and a dial indictaor,

I get them within a thou or so by carefull tapping with a mallet and lots of dial readings,,,,,,,,,,,

I've also used a drill press and a dial indicator too,

lathe was easiest,,,,,,,,,,

works for feather shafts too,,,,,,,,,,

Um, c mark,

Did you catch Blue's location? Gonna be kinda hard for him to whip a lathe and dial indicator out of his back pocket!

Sorry, I couldn't help myself...

Blue,

You could get the spindle shafts at a cost of anywhere from about $4 all the way up to $12 depending on where you order them, but there's another way.

You can order a pack of four 3MM X 50MM Socket Head Cap Screws from Du-bro at: http://www.shopatron.com/product/pr...id=DUB798/101.0 for $1.55.

They're about 5MM too long so you have to cut them off, but I have been using them in both my birds and they work great. Now you have a shaft and three spares at a cost of less than 50 cents each (after shipping)! That's good too, because you're likely to bend the spindle shaft every time your blades hit the ground. As a matter of fact, don't forget to order yourself some more spare main shafts, you’re likely to bend that every time too.

Some guys have asked if the balance of the spindle shaft will be off if you use a screw and locknut as opposed to the stock threaded shaft with two nuts. Not that I can tell. The mass of the screw head and the nut are so close to the center of rotation and the weight difference so small that it doesn't seem to affect the head balance at all.

The other question that comes up is whether or not the threads on the screw chew up the damper rings in the head. I have not observed any damage in nearly a year of flying with this setup.
