Long EZ Height ??


Recommended Posts

Hi all, I just joined the forum. I bought partially built LongEZ 1675 from a lady in South Carolina, so I'm just starting. What is the distance from the belly of the plane to the ground right under the landing gear? I'm planning to use a L320 engine. If I use a 2-blade prop, does the LG need to be a bit longer, or should I go normal height and use a 3-blade prop?


Also, what size tires does everyone use on the main LG?


Thanks much.

Welcome to the forum, and congrads on your new EZ.


Follow the plans. (You Do have the plans, don't you?)


There are many EZ's out there with the O-320, and several prop makers who can supply a two bladed for the EZ.


The original plans call for 5x5. However many builders are putting a smaller tire on the mains. This makes for smaller wheel pants and a small reduction in drag.

The ground is located at WL -26.0

The bottom of the fuselage is WL 0.9 (i.e.26.9 inches off the ground.


When you start talking about clearance, are you going with the standard P-51 scoop or are you using a NACA scoop?

Waiter, thanks for the info.


I've enjoyed your website, that got me fired up! Yes, I have plans.


Can anyone tell me the height of a LongEZ under the LG?

the long ez main gear axle is at WL -22" the bottom is at WL +.9 so about 23 ". depending on the size tires used, the plans size tires are about 11.5" in diameter. so 23" + 5.75 for half the tire = 28.75"

Thanks for the info, all.


I'm looking at the fuselage, main spar, and thinking about the strakes. I'm designing retract landing gear and am figuring the length of the gear and whether I can fold them up into the strakes in a reasonable manner.


I'm an engineer by trade, and sometimes spend way too much time and effort designing things and I'll always say "Why won't that work?". Most of the time I find out why!


I'm just tinkering, but thanks for the info.

Maybe you'd rather buy retracts:



And before you reinvent the wheel, several folks have built their own. I'm sure someone has the URLs.


Yeah, they look cool. For me, not worth the extra work and expense unless you're expecting to cruise in the 250 kt range or better.
