If yes, how is it done? Thanks in advance Carlos ________________________________ Message 2 _____________________________________ Time: 06:05:06 AM PST US From: Kelly McMullen Subject: Re: RV10-List: Installing the engine cowl I am guessing that you really mean with a 3 bladed prop. AFAIK there is no issue with a two blade prop, as you just put prop in horizontal position. With 3 blade you have to modify the cowling to get clearance between the nose gear leg(cowl bottom) and the prop blades(cowl top), and it still is a PITA. With any prop, spinner clearance with front of cowling is a factor that you have to address when fitting the cowling to allow the cowling to go forward just enough to clear the baffle seals from the front baffling.

Because of the small clearance behind the spinner, you must keep the cowl near level while you raise it vertically. Working solo I use a couple of 2x4s, supported by stools, sawhorses, etc., on either side of the engine, to support the cowl. Then incrementally raise each end. It was still hard until I did Kellys mod - I cut the cowl to extend the existing nose gear cutout forward, about 6 inches. This lets you lower the cowl straight down. Not sure about structural integrity, so I put the cutout piece back in, by epoxying it to an oversize piece of aluminum, with nutplates around the edge. I attach it to the cowling with screws. You still may need to carefully trim the rubber snorkle pieces, the aluminum baffle ramps, etc. Just a note, on my first test flights some RPM settings gave a strange vibration sound. I determined one of those aluminum ramps was a 1/16 too long, and could vibrate against the lower cowl lip. A little filing, noise went away. -------- Bob Turner RV-10 QB Read this topic online here: http://forums.matronics.com/viewtopic.php?p=492460#492460 ________________________________ Message 9 _____________________________________ Time: 01:09:34 PM PST US From: Dan Charrois Subject: Re: RV10-List: Installing the engine cowl With my 3 bladed MT prop, I find the only reasonable way to get the lower cowl off is to remove the spinner. This gives an extra half inch or so of clearance to the prop backplate so I can get the cowl on and off. With that said, the modifications to the lower cowl suggested would seem to make things that much easier.
