Unless that SE-RG is pointing straight down, I have my doubts about 180 kts.

Recently, some performance stats were posted to the VOBA forum. I want to get everyone's input, so I'm re-posting it here.



Owners, please reply with details of your plane and what numbers you use for flight planning . . .



•         What model and engine are you flying? XL/SE? Fixed or RG? Engine?

•         What is your efficiency cruise KTAS, GPH, and altitude?

•         What is your speed cruise KTAS, GPH, and altitude?





(If you already posted your stats in the VOBA forum, you don't need to send them again. I have not finished compiling the results, so your numbers may not be listed below.)

Are others in the community seeing similar performance



This isn’t a speed contest, it’s a reality check. Post your typical flight numbers and I’ll compile them into something we all can use.
