Default CA hinges on GP Patty Wagstaff/55cc

I have a Great Planes Patty Wagstaff 25% ARF and a DLE55 gas engine. The building manual specifies CA hinges. Has anyone had any experience with this set up? My other Gas planes use Robart Super Hinges.

I have flown many nitro size planes using the GP hinges with no problems. Having said this On all my giant scale stuff I use the robart pinned hinges. CA hinges may do the job, but with the kind of money wraped up in 25% and larger, why take a chance?

I second that and would not run them. I have had them come out on 90 size plane. Robart all the way. Trust them the CA one's won't cut it.

we use to have a flyer at one of my clubs who flew a 33% Cap with CA hinges on a 3W-100 other than him i have never seen anyone use them on larger birds. He only had them on the elevators come to think about it

I have the GP Patty WAgstaff Extra with a Moki 2.10 in it. I used the CA hinges, it's about 5 years old now with many flights, so far no problem. BUT, the DLE55 seems overkill for this airplane. With the extra vibration and size of your engine, I would use a pinned hinge of some kind.

I have a FTL-45 gas engine on my Patty Extra 300.I used the Dubro heavy duty nylon hinges.
I opened up the slot where the CA hinges go and epoxied these in with 30 minute epoxy.
To keep epoxy off of where the hinge pivots,I melted some vaseline and dipped the hinge pivot
into it with the hinge folded back,then worked the hinge back and forth 3-4 times.Do all hinges like that first for a
control surface,then I installed them on the plane with epoxy and then install the control surface onto the hinges.Set your
hinge line by pushing the control surface on as far as possible,then flex the surface up and down once and let dry.
Never had any come out or loosen.Also you can remove the control surface by removing the cotter pins from the hinges
if you need to.

Here is the hinges I use.

I used the CA hinges on my Waggstaff and the Rudder came loose after Three flights. Stick with the Robart Pin type hinge.

I wouldn't use the ca hinges on this model. Use the hinge points instead. Don't ask me how I know this.
