What size prop is that Sheepyone? Sounds like it could be a tad bigger to me $%& Seems to go great though huh?

What do you reckon I should try...

Stonking set up.  :af

I would say if it's slower revs then coarse pitch.

Scale size on the Floh will need 28" dia so I am looking at around a 28" by 6 or 8

As far as I'm away larger size props are more efficient so maybe a larger dia with low pitch as you have said would give better thrust  $%&

Just found the info from Ian again, recommended with this tourquemaster are props between 20 or 22 x 10 for max power, right up to 28 x 12!! Best for mid range is 24 x 8, 10 or 12.

So the 28 by 12 is calling me....  ;)

I actually doubt it would turn a 28 x 12 that well mate, it sounds a bit big. 28 x 8 might be a good starting point $%&

If nobody stocks that size, Dave Pullinger can make one, proper scale jobster but may set you back a bit :af

I'd be tempted to try a few sizes, measuring thrust etc, then go for the correct size in a scale shape   $%&
Of course, you will have to build the model too  :study:  :ev

Done them ribs yet  :''

And here's me thinking I was going to see a picture of the half finished model when I got the posting e-mail  :banghead:

Are you moving into politics Stuey??  I am sure you didn't directly answer the "closed" question that was posted  ;D  ;D  ;D

Glad to see you are working closer to working on it again  ::)

Thanks Mr. J.... We are almost near to the point where I think I will be thinking about thinking about working on the thinking about working on this again.

Just found all the ribs when tidying up the workshop!

But did it though, does not look like it went in nose first, more cartwheeled hence the tail damage... Wonder if that indicate lack of rudderage... :co

I don't think you can tell anything about it's flying characteristics from the damage.  Unless you know who was flying it in what conditions etc it could have been a great flier and sh1te pilot, or a mid air prop hitting tail causing crash or anything really  $%&
