What IAS are people seeing during their flyoff without pants/fairings.
Today (at) 3500' running 25 x 25, I was indicating 134 kts. I know I've got
some rigging problems (which I hope are now remedied) and have been
dragging the airplane through the sky with a yaw. Just curious as to
what I should be looking for once I get her rigged right and flying
straight.

A whooping 3.2 hours and 3 flights !
BTW the RAM air is an INSTANT turbo, pull the valve open and MP pressure
jumps 1.9" !!!!!!!!! WOOOOHOOOOO. What a surge!!!!!! I spoke with Rod
Bower tonight and he's working on an enhancement and testing with Lycon,
and he's confident we can get 3" + boost additional with the BPE cold
air and forward facing servo Smile Who needs any stinking turbo !?
..... More to come

Great to be able to compare notes on this. We have just under 4hrs on
the airframe. Fairings and pants were installed for last flight to
address any balance issues. Some minor trim reqd for marginally heavy
right wing, but a reasonable amount of rudder trim required.

With pants, 25x25 gave us 168kts at 1500'
Dirty stall speed is 45kts (confirmed)

Jon Johanson is out flying as I write this email. He is absolutely
stoked with the performance of this aircraft - as am I. Can't wait for
my turn . . .

Cheers,
Ron

I know when I first flew mine, I was very disappointed in the speed, but
when I put on the pants and fairings everything came up to where it should
be. I unfortunately do not remember pre pants #s. You will probably see at
least a 12K increase though by adding the pants and fairings.
