I have a Tom Dixon Vector 40 profile kit. We're thinking of finishing it in a sort of Blue Angel style.  Just curious if there's a way to mount wheel struts in a foam wing, and to be able to make it a Tricycle plane.  Just thinking.

How far along is the wing?  You can mount landing gear into a foam wing, you just have to build in hard points to do so.  Somewhere on the internet there's a set of pictures by Bob Hunt on building foam wings, he details his method for landing gear mounts which should work as well for trike gear as for conventional.  In fact, if you want to be tricky, you can mount the landing gear hard point right on your desired center of gravity, and either angle the legs forward for a conventional gear, or backwards for a trike gear.

This will be less added work if you're looking at a set of cores and haven't put the wings together yet -- a lot more if you need to hack them up and retrofit something in.

For the nose gear, I've done this successfully, twice.  Basically, leave out the 1/2" balsa below the bottom motor mount beam, from the nose to about four inches back.  When you put the doublers on the nose you'll end up with a deep pocket.  Then mount your front landing gear to that motor mount beam.  I've done this on two planes -- one has well over 500 landings on it (perhaps 1000), mostly on rough grass.  The other is scale so I had to mount a stub block to get the geometry right.  It's also fresh out of the shop, so it's only had one flight, but that wasn't cut short because of landing gear issues.

The technique I use does require a little block with a slot milled into it to hold the front of the gear in, held in place with 2-56 screws and blind nuts.  I machine these from aluminum, but you can probably build one up out of plywood instead -- it's really just there as a locator; all of the landing loads on the wire bear on the engine mount.

Hi Allen,Just above your post is tutorial on mounting LG in a foam wing. Hiding in plain sight?
