I have been flying N439RV for three years (340 hrs) and I love it, but I have a minor rigging problem that, if I correct it, would probably reduce drag. When I...
Doug, The need for nose down trim, and therefore the amount of the counterweight sticking into the slipstream, will vary greatly depending on speed and CG. You...
There are a number of aspects of interest here. 1. First, we'll try to answer the question "if my elevator counterweight is XX inches high in cruise, how much...
First make sure your W&B is correct. I had a similar situation on my RV-8A. You have excess dynamic down force on the HS. Your trailing edge down (nose...
Kevin, Now for the $64,000 question. If the elevator is deflected down in cruise, such that the counterweight sticks up 3/4 of an inch, how much faster will...
To be 100% honest, that is a tough question for me, as I don't have access to the analytical tools needed to do an analysis, and I have no real world...
Doug on my last three 8's I put 9/32" shims under my front HS spar and that was always pretty close for my applications. Steve Raddatz ... From: Kevin Horton ...
Well guys I tried to post a photo in my album but it said I don't have priviliges to do that. It did let me delete some old photos. So, I'll just say that I've...

I'm planning ahead for all the things I need to purchase or do before the first engine run, hopefully coming up in Late May or early June. How much break-in...
2 cases (24 quarts) oughtta cover you and then some (give the extra away to the next guy). FWIW, I did my first oil & filter change & screen check at 11 tach...
Kevin, You need 8 qts for fill and plan on a quart burn per 4-5 hours. Tom Wood RV 8 N184TW ... From: Kevin Horton To: RV-8@yahoogroups.com Sent: Sunday, April...
Hi Kevin, Oil is cheaper by the case, and one case (12 qts or liters) is sufficient. I usually run my engine's 15 hours or so on mineral oil, change the oil...
Kevin, I added 3 quarts during the breakin... Tim ... From: Kevin Horton To: RV-8@yahoogroups.com Sent: Sunday, April 13, 2008 9:54 AM Subject: [RV-8] How much...
Kevin, If you have a couple of quarts of mineral left after you feel you have seated the rings, there is nothing wrong with running mineral another oil change...
... Hey Kevin I used one case. HOWEVER, I have the A3B6D (essentially the same as your engine) and it spits everything over 6 qts out. I would put in a max of...
while attempting to install my electric elevator trim i disscoverd that the hole im using for wire routing is the same hole that the trim servo jackscrew runs...
Ha, I'm glad to hear you say that anything over 6 gets spit out. I can't relate to my flying mates who go for 25 hours at 7 to 8 quarts without missing a drop...
Kevin, You should plan on at least 20 hours of flight with the break in oil. Lycoming says it could be as long as 50 hours. The guide is to run the engine...
I wouldn't do that. Drill another access hole and run the wires through. The access hole where the trim servo sits is plenty big enough for you to get your...
Kevin, I did 2 cases. I used the first case for initial fill and burned about 1 qt per 7 hrs. I did an oil change at 25 hours and the second case went about...
RV-8 folks, Could someone please elaborate their experience with the method of squeezing the aileron trailing edge for aileron triming. Thank you, Bruce...
Bruce, I had a heavy wing and squeezed the aileron on the light wing with a pair of flanging pliers that had the jaws duct taped so they wont scratch. Just...
Hi Bruce, I used 2 ea 1" X 2" boards and 2 clamps on the light aileron. It doesn't take much, and I only squeezed the outboard bay. Fly and check it after...
A question for you aero-engineer types: Why does this work? It is widely used and obviously successful but I'm curious about the aerodynamics. JB N819WB FWF ...
The following explanation is my theory on why this works. It may or may not be correct. The aileron trailing edge has a radius. Air that flows along a ...
Hi Kevin, I'd hoped you'd answer. Best explanation I've heard yet. So, to summarize: Squeeze the light wing, reducing the Coanda effect. The stronger Coanda ...
