PRE-FLIGHT

 

Bring small stopwatch/timer

   
 

DEPARTURE

 

Do not use flaps

 

Climb out at 110 MPH

 

Climb to 1500’ MSL and level off

   
 

CRUISE

 

Limit prop RPM to 2200

 

Check engine gauges especially CHT and Oil Temp

 

Trim hands off level flight, Full rich mixture

 

Do 2 clearing turns

   
   

NOTES

As mentioned before, use common sense. Don't cook your engine and don't shock cool your engine. These tests might be best done over several flights in conjunction with other tests.

NOTES

 

Although this climb test can be done at slower airspeeds, BE CAREFUL! At 80 mph and 70 mph, this aircraft is at a very nose high configuration and is on the back side of the power curve. Unless you have a great deal of prior experience with the RV-series of aircraft, 90 is probably as slow as you need to go for these tests.
