A few weeks ago I wrote that I had run up the engine to 4500 RPM, but= that was not WOT. I went up and ran it today,WOT, and got the following= results.
 
 
Temperature today~ 70 F
Humidity- high, maybe 80%
RPM 5660
MP- didn't remember to look
Prop Catto  74 DIA x 88 pitch
Engine 93 13BREW N/A
Primary injectors - stock, 28 lb.
Secondary injectors  stock 40 lb.
PRSU RWS 2.85/1
RWS EM2 said it was making 161 hp. at 5660 RPM
Tail wheel was tied down, the brakes don't seem to hold at WOT even= on dry cement.
 
My induction system was not hooked up, it was configured as shown in= the photo.
I think, based on the above, that I might see 194 HP at 6800 RPM, whi= ch is 2386 RPM at the prop. Anyone who can calculate this more accurately,= or shed more light, please go ahead and 'splain it to me.
In any case, I'm pretty sure it will be able to get off the ground.=
 
The airworthiness inspection is completed, taxes are paid, and regist= ration should arrive in the next few days. I'm still working on my tail wh= eel endorsement, I should have it by the time my instructor makes his next= car payment, I hope. Also, trying to get some time in some tail wheel RV'= s. There are several people who have offered to take me up to get a feel= for how they fly.
 
Steve Beckham and Mark Hatch graciously flew up to give the plane som= e scrutiny two weeks ago.
 
So, depending on how the stars line up, This plane might be airborne= by the end of the month.
