I am following this thread with great interest. I would love to find out details of the propeller design i.e. blade angle, twist, chord, etc as well as its mechanical design.

Gearing the prop to allow a smaller prop perhaps as Stephen - Prosper,is doing ?

I can't imagine the forces generated in the powertrain of a model this gigantic, but surely they'll be hefty, with a capital h,e,f,t and y. Now, that's not to say that Medieval Europeans said - Oh, like we can't like build these like, yeah, windmills, because we've only got these plastic gearwheels from China . . . in other words there must be a 'gearing solution' for a 1/10 scale Hurricane to be had - but a daunting project, maybe . . . Also to consider is that with gearing where the prop turns faster than the motor, the rubber motor will be bigger (thicker) than for a direct-drive setup - so even more heft required . . .

Picture: suggestion for suitable winder for your model.

I am 100% confident that a geared setup would be doable, but I'm not sure I can see its worth, when I know that the model will fly with the 'standard' rubber motor/prop combo. I would also be limited on space in the nose due to the location of the battery box for the gyro. Yes, I could move it to another location, but even at 1/10 scale, there's not a huge amount of area in the nose itself. Then to add in more weight with it requiring a beefier motor, I feel it would be adding in complication for the sake of it.

Don't get me wrong, I can see the benefit of a geared setup in a rubber model, I just don't see the benefit in this particular application.

Thanks for following along! Although I'm not sure how much information I can give you on the propeller blade design, due to tapping into Ivan's many years of flying duration model airplanes - with a lot of success!

The details I can give you though are as follows:

Blade length 9.5"
Blade width at widest point 42mm
Blade carved out of 3/8" medium c grain balsa

As far as blade angle goes, that will be something I can measure when we have carried out the initial setup and trimming flights. Again, I will be tapping into Ivan's knowledge base for this.

I have actually made a start on the carving of the blades today, and have one complete blade.

I'll have to resize some images so I can upload them on to here so you can see the prop hub assembly.

Thanks Mark, an information is appreciated. My winter project is restoring a mates Ta152H from the FSMWW2 book doubled up to 10:1 scale also. I was considering making a Maxfliart bucket prop, but making an Ivan type prop would be great!
