My first few flights were without using my "belly board". The last few flights
have been with the belly board. I find that my landing role out is shorter
using the speed brake.

I found belly boards and flaps have different functions.
Flaps increase drag and lift.
For flaps you need more ground clearance than the standard retract KR has.
The belly board, when placed at the main spar, just increases drag without
increasing lift.

Just for confirmation:
1. a Belly brake will have exactly the same desired effect then.
2. No need for both split flaps & a belly brake.
If the above is the case, I'll not bother with the stub wings only
split flaps, but only install a belly airbrake instead.

Split flaps work great! I chose split flaps preci
They are a good choice for flaps in a small mechanical footprint, the
problem that you may encounter is drag. Split flaps produce a higher
amount of drag than other flap designs. Considering the weight of the
KR, to rapid or to much extension on to large of a surface could cause
rapid deceler

Hi Mark & all,
What was your experience with your split flaps? I intend to make split flaps on
the inboard wings only, all the way to the rear spar. I found a nice picture

I did that test for real today, since it was a calm day and I had lots of
time. Reality is closer to a 50% faster descent rate with flaps than
without, if you can believe what I

One thing I did test pretty carefully was glide ratio. Bottom line from
8000' to 6000' is that I got 16.0:1 at 97 mph, which makes me feel pretty
good, considering how draggy my plane is at this point. That's an

Mark,
If you are doing landings from abreast the numbers with a big slip,
you might make it with a dead engine. Did my landings the same way in
the Mustang. When the engine quit for real, it amazed me how fast it
came down with a prop stopped. Bobby

Hell Mark anyone with a small amount of intelligence could figure
