I honestly don't ever remember seeing them before, anywhere. The ones that came with the cmp where the 1st of these type I have ever seen.
Could be wrong though. If Robart did make at one time, problems or no demand, would have made them dodo bird.

A Google search for Robart Horny Hinge comes up with lots of hits but I'll be damned If I can find a picture of one. I can't remember where I saw them now. The point is moot if they aren't produced anymore.

I finally found some Robart horny hinges today at the local Hobby Bench. They are part number 302. Nice and free moving. They seem pretty strong given the small 1/8" size. I'll feel much better using these.

Almost finished with my Cessna. Had to add some weight to the nose. It was tail heavy with the power .46 motor and 4s thunderpower 5000. Hope to maiden it this weekend.

Ahh haa, maybe I'll hunt around my LH's
"horny hinge"

Thks for the part number joe!

I use Robart hinges (and horns)a lot, normal white glue or even canopy glue work very well on a a/c this size.
Just don't use ca, it makes them brittle and will break.

Somebody scored a great deal on that hinge sale! I bought the Zap hinge glue that Robart recommends. Basically a wood glue with additives. Zap Hinge Glue. I agree that CA would be bad news on this type of hinges.

I used the Robart 1/8" hinge points and the Zap hinge glue late last night on the elevators. I'm quite impressed. They're very securely attached and they operate super smooth. I had zero problems with installation. Well maybe not zero. Dopey me never really looked closely at or measured the hinge points that came in the CMP kit. I assumed they were 1/8" and that's the size Robart hinge points I ordered. It turns out the CMP's are 2.3mm or 3/32". That would be the Robart 1/2A hinge point equivalent. No problem at all. I had bought the Robart 50 point combo bag and it came with a super nice aluminum and steel hinge drilling jig. (kit part #311) I simply opened the existing holes up to 1/8" and I was ready to rock.
I've been in this hobby in one form or another since 1973. Can't believe I never tried these. I know they've been around for quite a few years. This is my new standard hinge!

Ditto on the Robart hinges, the other standard is sullivan carbon rod. No need to make dead straight runs, easy to use & tough as nails.

I used the 1/8" also & the sullivan rod for the rudder- Kept the split elev thingy for now, but added a brace.
The tube is 7.8mm thick so a 8mm hole works great. keeps it from moving around too much but lets it slide easy. Just put a smear of soap on it to help slide
Irish spring works nice, but I just like smell- ivory ok i guess too

tracon-

How did you synchronize your flaps with your radio. Did you "mix" them (master & slave)on the radio or did you hardwire both flaps with a y-harness?

Turbojoe,

I had my maiden flight last week. Had some minor damage on the first take off because I was worried about the power so I over compensated on the rudder a bit, but otherwise it flew great. And about your concern about underpower with 4s. forget it. The plane roared off the runway and flew gre
at at 75-80% power with my setup of e flite Power 46 motor and 4s flight power 4270 batteries.

Sorry to hear about the mishap. It's great to hear that there was no power issue though. I should be in good shape running 6S Li-Po then. I'll hold off building the A123 packs until I know I can get away with maybe a 5S2P pack of those cells. I got my motor mounted up tonight. I still need to cut about 1/4" off the mount cage so I can get the spinner back closer to the cowl. That 40mm motor sticks out there a ways. I'll try to get a chance to run it up this weekend and see what numbers it puts out. I'll use the Eagle Tree as it's probably more accurate than the Wattmeter.

Joe

I went one pc wing, y-harness on both ail&flap, wing side, 2x 6" extension on Rx side.
Only two wires to connect, don't have to fumble around Rx or move it and trust the wing a bit more too.

Just curious why everyone wants to glue the wing together. The Sig Somethin' Extra uses cup hooks and a rubber band to hold the wing halves on and I never lost a wing on that high performance plane. The multi piece wing is a plus for me as I need the room when trying to carry several planes to the field. Have there been any failure reports? Again, I'm just curious.

Joe

Mostly, just cause I like it that way, less pc's to cart around, less wires to fiddle with.
But I also just trust it more.

I got hold of a preowned CMPRO Cessna 46. The ex owner flew electric and crashed wrecking the firewall and needed a rebuilt which he didn't bother. I got the plane as a result. What I did was simply cut a piece of hard ply the size of the firewall and epoxy it down. I was using an SK 50 swinging a 13x4 prop. My initial CG was way back but what the heck I brought it off for a maiden flight and nearly crashed it! The plane just climbed so nose high that no amount of down elevator could compensate.

lucky I managed to make an emergency landing after a few heart wrenching spirals and wing dropping. The landing gear nose wire was a gonner and the firewall gave way. I guess the epoxy was not enough. This time round, I gave it a good layer of epoxy and hope it holds. I had an SK 90 so I made some adjustments and fitted the bigger engine in, after which I checked the CG this time round, it blances way better into the 65 mm mark. I have yet to bring this plane up. I hate puttingt in dead weight and for the start, I do not have so much weight. So I though the bigger engine would balance better. However, I have never overpower any plane by such a big extent. Do you folks think this plane would fly with an SK90?

I have also attached pics.
