Terry, I'd climb to keep my speeds low and power up. Temps MAY be a
problem but probably not.

Hi all,
My question is to anyone flying the 300 hp version of the XL.
I need to know in an XLRG at 5000 msl, will it stay below 140 kts,
with the gear down at 23 x 2300-aprox 65% power.
Here is the issue:
I am up to the flight test phase. Scott Swing told me last week if I
take the main gear doors off, I could go to 140 kts or so with the gear
down I have a zero-time Don George rebuilt 300 HP Ly IO-540K, w/ a 3
bladed, controllable pitch. Aerocomposite Inc. prop.
One school of thought says don't raise the gear, but I want to keep a
high MAP (at least 65%) for 30 mins or so to begin the process of
seating the rings. That's if no other first flight issues require a
return to base.
The other option obviously is to raise the gear on the first flight
which will take me to cruise speed regime at 5000' and 65% power. I
would the speed increases pausing at 10 knot intervals.
Anybody been down this road, flight testing a new airplane with a newly
rebuilt engine?
Thanks,
Terry
