Can the lower cowling be easily removed by one person or does it take two people to remove it.

Thanks

The only one I've seen go on and off was split top and bottom like the factory designed it. Was very easy for one person. Brings up the question though, why do some modify it to split it on the side?

Edit: I missed that this was for onex.

Are you talking about a Onex lower cowl, or are you referring to a modified Sonex cowl (split horizontally)? The lower Onex cowl can be removed and installed by one person, but it's easier with two. I have no experience with a horizontal-split Sonex cowl, so can't comment there.

Yes - I would like to know if the Onex cowling can be removed and replaced by one person or if it takes two people. I live 40 minutes from my airport and its sometimes a pain finding someone to help me with cowling removal and replacement. My wife does not like driving to the airport to help me for three minutes with cowling removal when necessary. I just sold an RV6 to build a single seat aerobatic airplane. The maintenance on the RV6 was a bit time consuming. The Onex is at the top of my list but for relatively inexpensive single seat aerobatic plane. I am hoping the maintenance is not quite as time consuming. Easy cowling removal is a big plus. Any info on the Onex concerning ease of maintenance or other practical concerns of aircraft ownership would be appreciated.

Yes, the Onex lower cowling can be removed and installed by one person. It takes a bit of practice and care, but it can be done. Two people is a plus, but not an absolute necessity.

Thanks - my wife will be happy to hear this

I have the horizontal split on my Waiex cowl. It can be removed and installed by one person. I have an adjustable padded shop stool on rollers that I position under the cowl, pull the bottom and side pins, carefully clear the prop and just rest it on the stool. Install is just reverse the process.

The reason I went with the horizontal spit was I never liked the vertical split. When I converted from nose to tail, I had to do some fiberglass work anyways so I went ahead and did the split. The nice thing about the horizontal split is the ease of removing the top to do routine maintenance stuff and inspections. I'm glad to see Sonex went with the horizontal on the Onex.

I guess it's all in what you get used to. I'd bet I can remove or replace a standard Sonex cowl just about as fast as a horizontal split cowl. Don't need a shop stool underneath it either. :) (Sorry, I couldn't resist!) And lots of times you only have to take one half of it off, so it's pretty comparable to taking the top off the horizontal split cowl in that regard.

With the vertical firewall it's easy to do a horizontal split.

Joe,
You are the first person I've heard to say the standard vertical split is just as quick (and can I assume as easy?) as the horizontal split cowl. I was planning on changing to the horizontal but wasn't looking forward to the extra work as the KISS principal appeals to me most. This gives me hope. It would be nice to hear from others who also feel the standard vertical split is ok.
