MD 500 tail gears

Has anybody had the tail gears strip ?

Only when planting the tail blades in the ground.

Never on the 600 or the 700.

Have you had them strip or was this just a general question about the integrity of MD gears.

Tom,

Have you checked the tail pitch lever to see if it had made contact with the gears?

[tomro]

Can't find any reason for both gears to strip. All the bearings are okay as well. I had just spooled it up and just before lift off the gears stripped.

Yea, that's very strange. I piled in a 600 a few months back and didn't have to replace any gears.

your new gears are on the way though.

[tomro]

I got the new gears and put them in, had to do some trimming on torque tube gear to get it in and it worked good. I still don't know why the original gears stripped. PS did get the heli up for it first flight today.

[mdhelicopters]

Excellent, how do you like it?

[tomro]

It was good, seemed to be real stable. Still have to figure out governor problem when I spool it up,but I'll figure that out.

Congrats on the maiden.

[mdhelicopters]

Cool, glad it's back going. What issue you having with the gov?

[tomro]

I'm using a YEP ESC with a 720 Skookum, when I start to spoil up I have to flip the throttle hold on and off real quick then it'll lock into the governor, if I don't flip throttle hold on and off it'll just spool up to maximum rpm.

[ChuckL]

By max speed do you mean 100% throttle if so any idea what the head speed went too. This could be the reason for the stripped gears if it spooled up beyond design limits. I can't help with the Skookum/YEP setup never used either.

[mdhelicopters]

Yea, something sounds as if it's not configured correctly.
