Congratulations!! John
Everything looks pretty nominal for your
set up. Do you have an thermostat in you cooling system or not? The reason I
ask
Is while 190F if fine, but if you are
current producing 135-145HP and put a 2.5:1 on it and end up producing 200 HP
then your may find
Your temps are going to go over 190F. Now
if you have a thermostat holding it at that temp, then it may be that you do
have sufficient capacity for more HP.
200HP in a tailwind? Boy, you are going
to blow most things in the sky away.
Again, welcome to the rotary fly club

First Flight
First off a GREAT BIG THANKS!! to all the Tailwind drivers
who took me for flights and let me handle the controls. This morning the
conditions were near perfect, so a moment of solitude with the maker, I
climbed in and said, self this is the moment of truth. First flight in a
Tailwind was with Brian Alley at Urbana,
2001, and my much younger mind which absorbed the pattern and final
approach like a sponge and even today it was like it happened yesterday.
Malcolm and BobD in different flights, gave me lots of pointers, there was a
joke at one time that I had more time in Tailwinds than some of the owners.
I do need a 2.5 to 1 redrive, as the engine needs to turn
faster to develop the hp. I need to get the engine up to 6200 rpm to
develop over 200 hp, but for now I'm really happy. It is very
stable, controls are very sensitive compared to the Colt. With 4 notches
of flaps the approach was too hot at 85, but on the uphill grass runway the
roll out was about 500 feet
oil
temp
190 I think my muffler is blocking the cowl outlet to some extent
I will be sawing half the brake pedals off, as it is too
hard to taxi with the rudder with out riding the brakes. It doesn't want
to lift off well with the wheels sliding down the runway.
