First Flight

We have today flown off the remaining hours of the test schedule on 'XDY 
with no problems at all. Near perfect conditions made for some great flying 
with Peter Kember again in command.
Once again the ASI seemed about 10kts over even though we tried 2 different 
mods on the pitot, so now we're thinking it might be the static.
Some of our figures recorded were:
Cruise at 4950rpm at .3C OAT:
821 degrees C EGT, 120 degrees C CHT, 66 degrees C water and oil temp 109 
pressure 57psi.
Strangely enough increasing the rpm at this stage reduces the EGTs quite 
dramatically by 50 or more degrees.
Climb at maximum gross weight 750 fpm.
On one flight, running at around 5 gallons below maximum gross weight we did 
a timed climb from 500 to 1500 ft at 53 seconds, admittedly with a small 
zoom at the start.
Next week we intend fitting the new tailwheel (retaining the current wheel 
drive and mounting) and while we have the resin brushes out we will move the 
battery back behind the D panel to make the loaded CofG easier with empty 
fuel. We will also fit the new plenum chamber.
For those still busily building, keep at it, IT'S WORTH EVERY MINUTE.
Dave Watts 229.
