Need a little help. LG rips off.

[Paul Taylor]

Guys
This is the second time I ripped the gear off this Vector. ( I did the same thing on my first one.)
I even put some thin fiberglass on it.
How do you mount yours?

Triangle stock reinforcement.

It is better rip the LG, than to break the fuselage in half. I would put plastic screws. They will be ripped apart, but the fuselage will remain intact.

Consider extending the plywood forward at least 1/2 inch and add triangle stock reinforcement where possible. (Using nylon bolts is a good idea too.)

It appears that the glue line broke at the front where most of the impact stress would be imparted to the landing gear assembly.  It also looks like the glue there did not bond to the joining piece in the fuselage.  Could there possibly be fuel (nitro) seeping into the wood there?

At any rate there certainly is not enough bonding area for the glue and the advice to use triangular stock to provide a much broader gluing contact area is probably the answer.  Also make sure on the repair that there is no latent oil in the wood.  If there is any oil at all, replace the wood, or it will probably beak off again!

I have ripped the gear out of both a kit Vector and an ARC Vector, so have some experience in the matter. Not to be a smart alec, but why is this happening? I hit a hidden sprinkler head in a grass field, and a hole in another field, both somewhat freak things not likely to recur. If your field is just so rough that this is likely to repeat, then go stronger. On the ARC Vector I added an external layer of heavy fiberglass around the LG mount area, up the sides of the fuse about a half inch, since by then its appearance no longer mattered. On the kit Vector with appearance points on the line I added ply doublers inside the fuselage to give more gluing surface, and made a longer (nose to tail direction) mount that would not be so prone to the "overturning" moment caused by the force coming up from the gear. That worked too.
