I’m wondering if the JP retract system in the large PC-21 has been reliable and if not, what issues?

I fly with Dennis Shrewsbury fairly often. We were together a couple weeks ago and he put several flights on his. The nose gear gave him some issues. The lower strut threads into the upper housing with a very fine thread. This thread was so fine and the tolerances not too good that it allowed the strut to just fall out. Luckily it fell out while rolling it back into the pits and was not lost. He added a couple of set screws to hold everything together. Seemed to do the job.

GBarnes, thank you for your response, much appreciated.

would be great if you could get Shrewsberry to weigh in here. Would love to see a picture where he put set screws.

would also appreciate what throws he ended up with on ailerons, elevators, rudder and flaps as manual has no recommendations

thanks

Roy, I don't think Dennis is on any forums or social media. Just not his thing. Most of his setup came from Ebel. We are scheduled to get together and fly the first weekend in December and I'll see if I can get you a picture or two.

Thanks that would be very helpful. Would be great if you could eyeball control throws. Can’t believe the kit has been out for a few years and no mention of control throws anywhere including the manual. I had PM into Ebel but never got a response. I wonder if others had issue with nose gear.

I am mainly on FB ..

I have about ninety or so flights on my pc21. The threads on my nose came loose after 60 or so flights. Never really had an issue except that my steering got a little clumsy. Took it out - put some thread locker and I was good to go.

Other than that it has been flawless.

Guldukat, thanks for response. Maybe I will be proactive and thread lock nose gear. Since you have yours dialed in I would be grateful if you were to post your control throws and flap settings

GULDUKAT

I did not do any of my linkages from the inside because they were limiting the throws.

All my turn buckles are on the outside. And I have maxed out all the throws.

Ok. Thanks Guldukat. I’m thinking 15 degrees takeoff flaps and 40 degrees for landing flaps. Hope that sounds about right

GULDUKAT

You don't really need any for take off. For landing add as much as you can to slow it down. Add a lot of crow as well. Idle at 400ft and let it glide on its own. It's a *****cat!

Thanks Guldukat.

another question; manual says CG at 213.5mm. Did you leave the CG there or move rearward?
thanks

Mine is a lot more tail heavy. I have the 1st version which is 8-10lbs heavier too.

GBarnes, sent you a PM
