My cruise is very close to Vne. Cruise is much faster than what Van publishes, and climb is still better than Van's specs. BTW, why is the constant speed uneconomical? I have never owned one.

I had my wheel pants fitted but not the leg fairings. I am wondering if anyone sees a reason why I can't fly with the wheel pants on, and the leg fairings off. At least till I find another day I can spend working on it to fit the leg fairings. Too much flying to do and not enough days to work on it. Tim ________________________________ Message 8 _____________________________________ Time: 02:11:53 PM PST US Subject: Re: RV-List: CHT's and EGT's Spreads? From: Doug Gray I thinking about these very questions myself and went to the Skyranch Eng Manual for some guidance. To summarise for cruise: Normal EGT range: 1200-1600 F no mention I have found for maximum Oil Temp: 160-245 F with minimum continuous 165 CHT: minimum 150 F, normal 350-400 F (435 for turbocharged) The Skyranch recommendation is to impose a secondary redline on CHTs of 400 F for normally aspirated engines, leaning should result in CHTs below this. The issue with uneven temperatures is possible uneven cooling of the cylinders leading to cracking. The proposition is that large variations between cylinders implies uneven airflow around the cylinders. The recommendation is to balance the temps with baffling/deflectors. This makes sense to me and it is the reason I am fitting individual cylinder CHT monitoring.

It is right above the oil screen housing next to the breather port. I'm using that one because it already had the hose fittings, but mainly because I couldn't get the #$%&*@# plug out of the center hole.

Better yet, try a leg fairing on one side and a pant on the other. You never know, you might like it like that- somewhere on your plane should be a big sign that says "EXPERIMENTAL", so whatever floats yer boat. 8-) (we now return you to your regularly scheduled ?: Can't think of any particular reason not to fly with your pants on and your leg thingies off, unless it has something to do with the mile-high club or somethin'...)
