About this Plan

Hummingbird, a 32 in span half-A cabin free flight by Paul Plecan from Flying Models.

Quote: "An .020 engine for sport flying or an .074 for a contest climb - take your pick, Whichever you choose, this ship won't let you down.

Our Hummingbird was designed mainly as a beginner's model. It features good performances, ease of adjustment, and neat appearance. Any midget engine can be used, the smaller ones (.020 cubic inches) providing excellent sport-flying performance and the larger (.045 Class 1/2A and .074 Class A) engines providing spectacular contest-type flights.

If this model appeals to you, the first thing to do is to check the Bill of Materials at the end of this article to make sure that you have enough supplies. If not, a trip to the local hobby shop will fix that. Since the plans are full size, all you have to do to have a complete set of plans is to trace a left wing panel and a left stabilizer panel.

To get the model built in the shortest possible time, cut out all the necessary parts in advance. Once you have everything cut out, you will be amazed at the speed with which you can slap this crate together. Grab a sheet of 1/8in balsa and get going on these parts: two complete sets of wings and stabilizer tips; two each of F3, F4, and F5 ; one F2; one -6 ; and the rudder. (Trace outlines onto wood by putting carbon paper between plan and wood. Or, if you want to, prick a series of pinholes through the plan onto the wood.) Now cut out the ribs, as required (see plan for quantities). Also cut the various nose blocks to shape. Trim the wing spar stock as shown, and taper the tips of both wings and stabilizer spars... "

The Hummingbird makes a very pretty electric R/C model. The red/yellow/green one is mine and flies very well with a 50 watt motor and R/E/T control [see more pics 004, 005].

Hi, here is my Hummingbird that was built by a long lost friend probably over 60 years ago [pics 006-010]. It was set up for single channel. I’m hoping to get it airborne soon. Cheers,

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
