Thanks Greg for reminding me, while living in Sth/H/Lands quater century ago I had some fun flying those rubber powered micro lights with hand made balsa props in the brand new huge basket hall the Council just completed, I was leasing it for 5bux (OZ) an hour, those were the good old days. Even more fun trying to get the model down without damage with made up 8m long poke stick after being tangled up in spider webbs, LOL.
There's a bit of difference in those and RC powered ones at 7K RPMs.
Yep, you right, us creative modelers can build just about anything if we set our minds to it.
I'm getting better with my 2nd. one, even con-caved after spending some 4 hours on it so far but only half finish.
Over the decades I must have modified hundreds plus props to suit my needs because I can never get the ones I'm after, easy fix, just cut it, re-shape it, balance it, and off you go. LOL. Cheers.

I paid more attention to this one.

Under 3 gram props.

Making my own props from whatever got on hand.

If I can't buy it I make it.


Custom made to get the best out of it.
