About this Plan
Pleaser. Radio control sport trainer model, for electric power.
Quote: "Here is a really versatile electric sport plane that can be built in either rudder/elevator or aileron versions with either 05 or 075 electric motors. It builds quickly, too! Pleaser, by Stan Wilson.
As a youngster of 34, I do not remember the excitement that came with the first glow engines. However, I was obsessed with the first stories about flying radio controlled models using electric motors. I started using windshield washer motors and motors from cordless trimmers. I destroyed four of these home-brews before I bought my first Astro 05. I stuffed it in a Super Malibu, and the thrill was worth the effort. My next success was with the Kraft electric Cardinal. I retired it with about 200 flights and several ounces of epoxy. I then built and flew the Astro Sport (oz12092). This is a fine model, but I wanted something that more nearly resembled a real airplane. I have been building and flying rubber scale for over 10 years, and I think that a model should look like a real plane.
I wanted a plane which would be capable of simple stunts, capable of flying in 10 mph wind, and steady enough for relaxed Sunday flying. I searched over 200 magazines for models which had these characteristics. After noting the dimensions of over 20 cabin jobs and about 10 airfoils, I settled down to put them all together. I eventually came up with what I call the Pleaser.
The original model now has over 100 flights using two power plants. I first used the Astro 05XL. This gave very pleasing flights, and was very stable. It would climb to about 300 feet easily, and could perform loops and very slow rolls. I fly with a four-channel, miniature Cannon radio. For all of my flights with the 05, I used coupled rudder/aileron.
After mastering this power plant, I installed my Astro 075. What a performer. It almost jumped out of my hand on the first launch. It climbs to about 300 feet in the first 30 seconds. I have performed multiple loops, rolls, and split-S maneuvers with very little loss in altitude. The only drawback of using the standard 075 is its short motor run (three to four minutes). I cured this with a throttle, which I will explain later. With this throttle, I can climb to the desired altitude, perform a few stunts, then switch to low speed and just putter around the sky for five to seven minutes.
I am currently flying my second Pleaser. With this one, I extended the wing by one bay on each side, which slowed down the glide speed substan-tially. I would not, however, recom-mend the longer wing for use with an 05.
CONSTRUCTION: FUSELAGE: I designed the Pleaser to build very quickly. Cut the sides from hard 1/16 balsa, the firewall from 1/8 plywood, and the other bulkheads from 3/32 plywood. I like rounded corners, so I use 1/4-inch triangle stock for the longerons.
Glue bulkheads two and three to one side at 90 degrees. After this dries, glue the other side to the bulkheads. This forms a rectangular box as both bulk-heads are the same width.
I then glue the bottom sheeting between the two bulkheads. This helps prevent warping when the firewall is installed, and when the tail posts are glued together. Next, glue in the firewall. I use rubber bands to hold the sides together for this. Next, bevel the triangular longerons starting about three inches from the tail post so that the fuselage sides are as wide as the 3/16 fin at the tail post. Glue together the fuselage sides at this time.
Complete the fuselage by gluing the remaining bottom sheeting and the top sheeting.
COWL: One of the advantages of electric power is that you can completely cowl in the motor, except for air holes. I cut the top, sides, and bottom from 1/4 in balsa. Glue the top, sides, and bottom together to form a four-sided box. You then sand the rear of the cowl so that it will fit flush with the firewall..."

* 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.
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.
