Does these horns suitable for my Sbach 342 (Black) EPO 1400mm (PNF) ? ..my broken horns had 4 holes for the screws, these one only have two as I can see... any suggestions?
the photo of the part missing of my Sbach 342 can be seen here:
They are nylon, so epoxy can let go if you don't sand the gluing surface with 60-80 grit. Or better yet Med CA works better and is lighter, test it if you want. Won't hurt EPO foam. Holds better than foam CA on EPO. Still need foam CA on EPS (polystyrene).
Depends on surface size and force applyed to it you may end up with a layer of foam or balsa glued to your control horn and loss a plane , if glued to a large elevater in a screaming dive then pull up hard eg pull out of a loop may rip off, id use bolts on ,if larger size planes,plus i place 1 screw to chech travel and elinement then the second screw
my favorite glue is gorilla glue.. use a srynge to apply water drop on them and they will stick like hard plastic... dnt get it on your finger tho.. it will take days to take off ... i also found that eating sunflower seed will help taking glue off your finger.. i guess saliva and sodium is the secret =)
the extra piece is an backplate, if you want to screw it on an wooden surface, you want to go trough the whole surfaces and put the backplate at the other side of the surface. when using with foamies it is better to search for an strong area on the surface, or create one (a piece of plywood or somthing) and glue that between the horn and the surface.
but if secure propably, you can use this without the backplate.
Some control horns only have one piece which you glue onto the foam. Others have the extra piece that you can put on the other side of the foam (the foam is sandwiched between the two pieces) and you use screws to hold it in place. Screws are not included with this, buy separately depending on thickness of foam. Easier to go to your local hardware store and buy a few screws after you get the horns. You can still glue these in if you want rather than use the other piece.
The extra piece is supposed to go at the other side of the horn with 3 screws going through the control horn, through the control surface and then connecting to the extra piece.
Hope this makes sense :)
There can not be installed without the other part it is the screw thread on one side you put horn and the other side of the wing, rudder, elevator, you put the extra piece to run with the fixing screws
Dont understand credit Just give advice as ive been building rc planes for over 35 years and have lost a few planes to mistakes ive learnd from,the diff today is a kit in the 70-80-90-cost a lot to buy and build a patern ship of 2m would cost me several thousands of dollars and thats me building them just building a jig costs money ended up doing a composits course just to learn about thermal plastics eg epoxy resins ps it glueing ruff up your surface to increase surface area 180 grit.see above comms my take on it
