Jesse,
My KIS TR-1 is about 100 pounds heavier than yours with a LYC 0320 150 HP.
How did you get that low of an empty weight with the 0360?
I would be interested in your true air speed at 75% power cruise with
that engine.
Also, do you notice not much prop clearance from the ground? That is a
concern of mine which I haven't fixed yet.

Hi Rob,
I think you mean Scott rather than Jesse.
I used a light weight starter and alternator, no vaccum system, capable but s
imple panel. The wing, ailerons, flaps, cowl, fairings, and elevator are ca
rbon fiber. I know I saved about 8 lbs on the cowl and about 15 lbs on the w
ing skins since I weighed the factory parts and my parts. No wet layup poly
ester parts, all prepreg. I never understood why Rich used wet layup for an
y of the parts. Simple interior, but nice cushions. The tailwheel and spri
ng are lighter than the nosegear. The 360 is about 30 lbs heavier than the 3
20. I use a 68x80 prince carbon prop and have plenty of ground clearance. I
really need about 68x84. The taildragger main gear is taller than the nose
gear.
What prop do you have on your 320? What kind of cruise speed?
The engine is 180 HP from the factory. My engine has 10:1 pistons, ported a
nd flow matched heads, and electronic ignition and put out 220 HP on the te
st cell. The added cost of these modifications is pretty small when buying a
new engine. Wide open at 12500', which is about 75% of 180 HP, it does 190
KTAS but it is spinning 2900 rpm with the current prop. I cruise at 12500 p
ulled back to 2700 rpm, leaned to peak EGT which is 8-8.5 gph at 175 KTAS. A
t 75% of 220 HP i think it would do 200 KTAS at 6-7000' but that amounts to r
unning the engine near 100% of rated power continuosly which I dont think is
a good idea and the indicated airspeed would be pretty high and it would be
using a lot of gas.
The speeds are with RV-8 wheel pants, and custom gear leg fairings and tailw
heel fairings. Those fairings all together are worth 15+ KTAS at 12500.
I would highly recommend the 10:1 pistons if nothing else. It makes a big d
ifference efficiency over the 8.5:1 stock pistons. Lycoming used 10:1 pisto
ns in almost all their helicopter engines.
If I did it again I think I would buy a low/mid time 320 and do a top overha
ul with the 10:1 pistons, head porting and flow matching, ebay the mags and g
et Pmags, ebay the carb and go to bendix fuel injection if it did not come w
ith. It would put out about 190 HP, weigh 270 lbs, and get close to 0.4 sfc
in cruise and cost $12-13K. That engine would be really hard to beat.
Cheers,
Scott

Scott,
Sorry about the name mix up. I have an old wood prop that came with the
plane. Not sure of the Mfg. but know it is not matched to the plane
and engine for the best performance. I have one pmag on the impulse
side and and older
Jeff Rose electronic on the other side. I haven't had a chance to
properly calculate the true airspeed but would think that it is
somewhere around 175 to 185 MPH at 8500 MSL full throttle and averaging
about 7.5 gal per hour cross country on
a 2.5 hour flight. The engine is rated at 150 hp with the low pistion
compressing ratio I believe in the 7.? to 1 area. It has about 470
hours since major over hall and about 350 hours on the airframe.
Doesn't use much oil and compression in the
mid 70's It is a great and economical plane for xcross country but I am
6' 1"" tall and 73 years so the getting in and out with the gull wing
type door is not to my liking anymore, would like a slider to just swing
my leg over and sit down. Thinking about
going the RV7 or RV9 way.

Hi Rob,
i am 38 and in pretty good shape and I am getting sick of the gull wing door
s. My airplane will do 185 mph at 8500' at 6.5 gph. I think the difference i
s mainly in the engine. Going from 7:1 to 10:1 compression (and expansion) w
ill make a large improvement in how much power you get out of the fuel.
For the price of an RV 7 or 9 you can get a nice 4 seat certified airplane.
There are some really nice early bonanzas out there for $60-70k. They are r
eally nice flying airplanes. There are some great deals out there right now
.

I remember one piece of advice on determining the maximum prop length.
Let the air out of the nose wheel tire, simulate a flat, and subtract a
little more. Vance had a saying something like, A prop should be as long
as a prop can be.
My Sensenich is 69", a friends TR-1 has a 65" prop.

1. What are your empty weights and CG numbers?
Empty is 835 lbs with a Oddessy 925 battery (24lbs), a parallel
