da 50 prop drilling
This might seem like a stupid question but how do you guys drill your props for the da -50 so the prop will be positioned right for starting? This is my first gas engine.
Do you use just one line in the tank for fuel pick up and one vent line and then use the same line (as for fuel to engine) to fill her up? Won't the fuel enter the carb?
Thanks

RE: da 50 prop drilling
I drilled mine the way they said to in the thread making the prop swing past top dead center at the 12 oclock mark. One day i was tunning the engine and i put the prop on in the wrong spot now it crosses the top dead center mark at the 9 oclock position and i like starting that way so much i allways put it back there. I also have a pinched nerve in my sholder so that may have a little to do with it. I do know the prop would smack my finger at least once on a weekend of flying before i switched to the downward flip now I never get bit. I also use a T on the input line and one vent line I know guys who use 3 lines and even one guy who put 2 fuel dots in and a check valve on the exhaust vent with a T so he can see the fuel return to the fill tank when his plane is full. I put a pad under the plane and watch it close but i also dont use an electric pump so i stop when i see a few drops an electric pump is less forgiving.

RE: da 50 prop drilling
If you have an aluminum spinner you don't have to worry about this, but if you have a carbon fiber spinner you'll have to watch your alignment.
Make sure you match up your spinner backplate and if the holes are already cut in the spinner you'll have to align the prop so it will fit between the tabs that the spinner screws onto. Take care to align everything so the prop does not touch the CF spinner cone after it is mounted.
I chose a CF spinner because it has less mass, allowing my motor to spool up more quickly, and it gave me perfect balance since I used a CF stabilizer tube and CF tailwheel.
