Hi Rob, I am based at Falcon Field, FFZ. There is another TR-1 here
with the 0320, owned by Pete Duran. Contact me at ftyoder@yoderbuilt.com
and we can talk.

John,
I have a wood Sensenich 68x72 on my TR-1 with the IO-240 B1B. I get
2050 RPM static at my field elevation of 1480'. At 3000', at full
throttle, it goes to 2800 RPM and IAS is 190/195 mph. Cruise at 2550 RPM
is 160/165 mph. I would like more static RPM for more HP at take off. I
think Prince and others have some pitch and length combinations that
might be a little more optimal.
I fly in Arizona and regularly take off of airports at 5000'+ alt.
with a density alt. of 7000' to 9000'. At gross weight, the initial
clime is only about 400 fpm.
I thin many of us would like to have an MT adjustable prop! Money is
always a consideration though.
Good luck, Tim

Subject: KIS-List: VMax - KIS TR-1
Gentlemenhat I have a 2-place KIS TR-1 G-BZDR which currently has
an IO-240 A1B fitted (125HP) spinning an MT Variable pitch 3-blade prop.
The prop has been sent for overhaul and the estimate is too expensive
for me. Therefore, I'm looking at downgrading to a fixed-pitch 2-blade
wooden prop.
The manufacturer will optimise the prop design to suit my aircraft
but needs some information which I don't have and wondered if you guys
could help. I used to cruise around at 145Kts at 75% power. However,
the prop designer wants to know the theoretical max straight and level
speed for the aircraft at full throttle. Anyone have any figures to
hand for a TR-1 with an IO-240?
I'll be selling the old VP prop if anyone is interested, it's got
360 hours since new but will need calendar overhaul.
John

If it were me I would pull the cylinders-and have the heads ported and in
stall 10:1 compression pistons.-- You would end up with 185-190 HP peak
and the engine would be significantly more efficient at cruise power.-
