About this Plan

Pushover. Free flight sport model for .020 and .024 engines, designed by Doc Baker.

Quote: "Ready for something new? Then try this pusher. Maybe its just a sport flyer, but it will give you hours of genuine fun. Pushover, by Bill Baker.

Ever since I first flew with a reed-valve engine, I have wanted to build a pusher. The Pushover is not a contest model, but a stable, rugged, and attractive ship. My wife was surprised that it flew at all and it surprised me because it flew off the board without needing any adjustments. The Pushover climbs slowly, using a full tank of fuel to reach the height a contest model attains in ten seconds, so no engine timer is used. The glide is just good enough to make good landings, so no dethermalizer is used either. Any pattern is safe with this ship as the torque is very small and the model is entirely out of the spiral propwash. I enjoy its remarkable ability to fly equal circles to either the right or left, depending on how the rudder is set.

An .020 or .024 reed-valve engine is recommended, although a tired .049 could be used. As a reed-valve engine will run backward, use a standard propeller with it, but if you have a rotary-valve engine, pusher props are readily available.

The model is constricted entirely of medium-weight 3/32 in sheet, (6 sheets), plus one strip of 1/4 in square, and some scraps of 1/16 plywood.

Fuselage. I started by making two right sides. Suggest you make one right and one left, as it saves time. The unbroken line on the plan is for the side pattern; the broken line indicates the final dimensions after the top and bottom are covered with 3/32 sheet. Cut out the sides, marking the positions of the 1/4 square uprights carefully, and join the upper and lower halves of the sides by cementing the 1/4 square uprights in place across them. When dry, cement F2, F3, and the plywood, F4, to the uprights to join the fuselage sides. Use a square to be sure the sides and F4 are at right angles..."

User comments

This was my very first flight plane! Lost it because the wind blew it into a forest where I couldn't find it. So I built another and then later lost that one too. I had put too much fuel in it so it climbed too high but then an updraft carried it up even further nearly out of sight. It landed far far away! I later migrated to R/C many years later when I was older and the radio equipment was more affordable.

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.
