I'm going to build a Sig Mustang (with the foam wing) and have a question - will the landing gear blocks stay in place?  I've seen a few of these over the years, and seem to recall the landing gear quickly became pretty loose ...

Thanks!

Dennis, no, they won't stay in place.  Poor design, in my opinion. If you are serious, talk to Bob Hunt or John Duncan about better foam wings with excellent landing gear fixtures.

Thanks Bill!  You're confirming my instinct.  Is John still doing foam wings, and - if so - does someone have contact info for him?

Dennis,

We used to router channels on the perpendicular to the gear block on the bent wire end. We used .125 ply.

Recess this piece in about an inch or so and yes, the top would have the airfoil shape. Put it in, trace the airfoil, mark for the cut out of the gear block, then remove it for the cut and fine tuning. Replace/remove as needed.

Epoxy the ply in place then the gear block.

All of this is covered with 1/16 sheeting, gear block and all.

Mark the sheeting to expose the channel for the gear block wire. Stick something short in the gear wire hole that marks the sheeting for placement.

Length of the gear block makes a difference also.

These were forward type Mustang gears with no spring loops as one would see on the nose gear of R/C models.

No reason why you cannot put a single spring loop on the gear.

We did it this way and it worked. I've seen tri gear models with dents in the wing from the wheels hitting the wing when the gear bent all the way back.

Now, whether or not this will work with Sig's foam wing or not, is the question? Plus, it's extra work and a bit more weight.

Be interesting to see how all these different foam wings cut by many Vendors, allow for the mounting of wing gear.

The only foam wings I ever worked with were those that I cut myself.

Good Afternoon Dennis;

  Tim's post alluded to Bob Hunt's technique for mounting gear blocks into foam wings.  He provided a step-by-step pictorial in another thread on installing landing gear in foam wings.
