Hi Rick,
Regarding the 3 blade prop, I bench tested mine and it seems to provide
adequate thrust. It is standard turning prop ( cw as viewed from the cockpit).
My concern is that even stopped, 3 blades will always contact the ground on
landing. Two blade might but if it is not straight up and down, probably will
survive. Maybe we can devise a light weight skid to save props? All the tall
grass is gone😂
My itty bitty 30a esc seems to work great.

Today I brought the HB1 to the field so George Moser could get a closer look
at it. Both George and Richard Pearsall suggested (as in edging me) to to
give the HB1 its maiden fight. George even provided a 1300 mAh battery that
just fit into the fuselage. How could I refuse? Besides I had the benefit
of having none other than test pilot Chuck Yeager (aka Richard Pearsall) to
do the honors.
The 5 x 5.5 3 bladed drone style prop (Jake take note) just didn’t put out
any thrust. Richard had a 6 x 4 2 blade prop that worked. Getting the 1/2
inch CG was achieved by adding more weigh to the existing weight. Since no
one had some double sided tape, a number 60 rubber band did the job ---
maybe.
A nice toss to the South and the HB1 was airborne and flying like nobody’s
business. It’s fast! The HB1 would have given Rick and Dave a run for the
money with their jets.
Heading northward (did I mentioned that the HB1 is fast?) Chuck, err,
Richard was making a left turn but the HB1 had other ideas. Like heading
into Mother Earth!
Found the HB1 in the swamp and wished I took a picture of it with the nose
deep onto the mud. But at least there’s a picture (attached) of it on the
bench.
Besides lots and lots of mud, the only apparent damage is a broken tail where
the wood dowel was inserted and a broken prop.
What caused the HB1 to go down? Who knows? We definitely know it was not
the pilot. Maybe the rubber banded weights came off, maybe it’s the cheap
servos or most likely the HB1 suffered from the 737 MAX Syndrome.

p.s did I mentioned that its fast?
