Chris,
That is way low for static with the RD-1C gearing. My
static with RD-1A is about 5400, of course with a much smaller prop (68x80). I
would expect somewhere near 6000 with the RD-1C.

Dennis,
What
is the max static RPM you can get? There are two of us with the same
Renesis, RD1-C and Catto 76X88 and the best we get is 4750. Does that
match what you get?

Renesis Flight Data
Friday I flew to Llano (70 miles) to pick up some barbecue
for the wife and myself. Take off was at 900' field elevation and I
climbed at full throttle to 7,500'. I used 7500' as the test altitude
because Bill Eslick's RV-6 flight test data sent to the list on 3/10/10 had
graphs for 7500'.
My aircraft is an RV-7A, Renesis 4 port, RD1-C redrive
2.85:1, Catto 76X88 composit prop, EC-2, EM-2, very quiet exhaust, DEI intake
designed for 6200 rpm, full 42 gal. auto fuel, 200 # payload (pilot with some
A/C tools, headsets etc).
Field elevation 900'
Climbed @
110 kts. indicated air speed - Full throttle climb to 7500"
OAT 70 deg.
at takeoff
Initial climb rate was 1800 - 1900 fpm
( I get ~ 2400 fpm with
only 21 gallons in the tanks)
@ 4500" the climb rate was ~ 1400
fpm
Water 188 F, Oil 200 F
@ 6000' the climb rate was ~ 1250
fpm
Water 188 F, Oil 203 F , OAT 60 F
@ 7500' climb rate was ~ 1000
fpm
Water 189 F, Oil 204 F
I leveled off for about 5 minutes than went
to full throttle again.
Full throttle for about 3 ot 4 minutes @ 7500'
MP 23.3 in.
Fuel flow - 12.1 gph
TAS 193 mph - EM-2
data
Engine: 6660 - 6680 rpm
Water 184 F, Oil 205 F OAT 65 F
When I fly at 7500' I normally use 8 to 8.3 gph
TAS 157
mph
Water 160 F, Oil 180 F
The barbecue from Cooper's in Llano was
great!
