Hey all, new Onex builder here. Got my tail kit last Tuesday and have the vertical skinned w/ clecos tonight. :mrgreen:

However, that gets me to the fiberglass tip part... Do the Onex fiberglass tips need trimmed to length to fit under the skin, or can they be fit to the tip rib in the as delivered condtion?

TIA!

I'm sure it's the same as the Sonex and the tail tip needs to be trimmed to fit (length and around rudder, elevators). This should be identified in the tail tip page of your plans.

Just for info, my Onex kit tail tip is not quite long enough to reach the back edge of the rudder

Needs trimming.

Thanks guys. I guess I'll finish the rudder first and take another look at the tip.

I also found that my horizontal tail tips required a lot of work to get them to conform to or blend with the slant line of my Onex horizontal tail (same was true of vertical tail tip). You might consider waiting to install the horizontal tail tips until after you've trial fitted the elevators in the interest of keeping an equal gap between the ends of the elevators and the tips. I didn't but wish I had.

I see what you mean. I thought mine should be like they are, but then I looked at some pictures of other tips. Well, more fiddling to do...

If I go by the measurements on the plans (1/4 scale) trimming the tips results in a tip too narrow. But not trimming the tips makes the shape wrong. I didn't see any mention of trimming the tips on the plans. I found a series of build photos that show 3/4inch cut off the tail tips to make the contour match the plans and I am thinking I will go that route. Onex 150.

Went through 2 sets of tips. Had to trim each slightly different to get the gap aligned.
Doesn't look like the plan but in order to get the trailing edge of the tip to align with the elevators...

I just trimmed mine about 5/8" each but I don't see any alignment problem. I assume that the trailing half of the tip should be at 90 degrees to the elevator hinge?
