Thinking a tail-skid

Post  roddie on Sat Apr 20, 2019 8:21 pm

I realized that I needed a tail-skid for this airplane. If not; the elevator-horn would scrape the ground. Shocked

I could have used a smaller diameter music-wire.. but I wanted a substantial skid.. for reasons outlined in the next paragraph..

I could utilize this skid as a pin-stooge anchor-point if need be.

I'd been thinking about this.. but put it off because I built a new C/L launch-stooge which has a fork which cradles the models' tail-plane just forward of a conventional-stabilizer.. (a popular stooge-design). I had previously been using a "pin-stooge" which requires the model to have a "receiver" for the pin to lock into. This had traditionally been either a music-wire tail-skid with a "loop" formed in it.. or a tail-wheel having a hole for the stooge-pin to pass-thru.. retaining the model.

Here are some photos of my new "fork" or sling-shot stooge..

Looking at these photos in retrospect.. I should add some soft-foam padding to the backside of the stooge-fork to prevent scratching the models' finish on release.

Here are some photos of my old "pin-stooge" which is still a very compact and reliable design.

There are many quick/easy ways to adapt a C/L tail-dragger to accept a pin-stooge link/receiver.

A safety-pin hooked onto the tail-gear..

A strip/tab of fiberglass window-screen material attached to the rear-underside of the model using 5-min. epoxy at the field.

My reason for building the "tail-fork" stooge was because of my two latest renditions of the Lockheed P38 Lightning.. and T33 "Shooting-Star".. which both have tricycle gear.

We're getting there.. I'm working towards getting several models in the air this season.
