Skymaster Large Viperjet Owners, do you permanently attach your wing-tip winglets?
Hey All,
I realize there is a giant SM Viperjet thread started by Ali that likely has this answer posted somewhere in it, but this is a simple question:
Got my SM Viperjet back from my builder RTF. The curved winglets at the tips of the wings have not been permanently attached but can be screwed on/off by 2 screws . My builder did this in case I choose to go without them. I want them on, but am not sure if:
1. there are any benefits/detriments to permanently attaching them
2. If attaching permanently how would you suggest doing so? Just sand down, hysol on, and crank down on screws?
3. If permanently attached does this prohibit effective running of wing tip lights later?
4. What have you all done to your winglets/lights/wings?
By the way, as a shameless plug for my builder- my builder is Bill Hatcher - his builds are phenomenal and VERY affordable and fast-his builds are as nice or nicer than most anything I have seen online or off. Planes are sturdy, retracts work with no leaks, support equipment is intelligently placed with future service in mind, it's all done very clean. Let me know if you want his contact info.

No real reason to glue them on. No structural or even apperance issues in my opinion. With just 2 small screws on the bottom, they can easily be removed for transport, repair/replacement or lighting installation/maintenance. Don't mess with a good thing!

The carbon pins hold the winglets just fine. I just added a strip of clear tape over the joint on the underside of the wing. Works fine for more than 75 flight so far.

Here you'll see my solution for both version of wing tips. I prefer to fly with the wing tip tanks.

I have had vipers with them both permanent and detachable. No real difference either way to be honest.
I never took them off the detachable version, and never once found myself wishing they were detachable from the fixed version. I guess just in case, its better to make them removable.

we made them permanent on Paul's Viperjet only because when he was trying to take them off, the bolt head broke off of one of the bolts, after that it was either use a brass tube to cut around the existing broken bolt, or just glue them permanent, so we glued them. Once we blended the joint with filler and painted it, it does look nicer, but that's just opinion

Usually I try to drill them out and make a small disaster into a much larger disaster

Yup, when you're dealing with wood or composites, all you need to do is get a brass tube that the ID of the tube will fit around the broken bolt. Sharpen the end of the tube, even cut some teeth into it if you want, and chuck it into a drill, let it cut around the broken bolt and you can pop the broken bolt right out of there

Hey folks not sure if this thread is still alive. I have a 2.6M viperjet that needs a repair. Where the mains attach to the wings, in the top side of the wing, there is a crack that needs some attention. How do I repair a crack from the inside/underside of the wing? Thanks! Tom

Anytime!
This is the way I use to fix stress cracks, however I use laminations of fiberglass with ca glue.. you can customize the strength of it adding as many layers you want.
