I've more or less finished the building of my tutor but have a question about the prop mounting.
Should the spinner backplate fit flush up to the drive hub on the crankshaft?
The backplate had to be threaded onto the threaded part of the crankshaft but the hole in the centre of it is not big enough to fit over the unthreaded part of the crankshaft which means that that the backplate does not fit flush to the drive hub.

Should I just drill the hole to fit?

Hi,

I take it ur using a plastic spinner, all you really need to do is drill a hole or use a prop rememer avalible from most hobby shops to enlarge it big enought so it fits, but dont make the hole too big, just enought to fit over........... when you drill or use the prop remer remember to both sides of the backplate to get an even fitting........

The Tutor 40 is a great plane to learn on, was my first and i still have it, althou i had big problems with the stock fuel tank, so i would recommened ditching it and getting a sealed one like a SLEC tank or something similar

Hope thats of some help........

A number of people have told me to get a different tank so assuming all goes well with my first lessons and I still have a plane, I may well change it.
