One 70 Toon (oz15317)

About this Plan

One 70 Toon. Radio control sport-scale model, for electric power. Wingspan 19-3/4 in.

Quote: "I have always been intrigued, fascinated and inspired by model airplane plans. I so enjoy looking at and studying them that I have wallpapered my workshop with my favorite model plans. Some older models call out to be built and flown to take me back to my childhood dreams. Other plans inspire creativity.

In November of 1975 Fred Reese published plans for the Littlest Stick (oz2331), then the smallest of the long line of very popular Ugly Stick (oz5175) variants at 19-3/4 in span. It was powered by a Cox .010 engine and was guided by the popular Ace Baby actuator for rudder only control.

The design has enjoyed a measure of popularity through the years, as it is irresistibly cute and flies well. Today most are flown with electric power and RET control by micro digital systems.

I had enough 'ugly' models in my fleet, but I just couldn't stop looking at the Littlest Stick plans. Then the inspiration came. I overlaid the Littlest Stick plans with a fuselage plan of a popular light plane. The lines were remarkably similar, enough so that I was able to quickly redraw the fuselage and rudder to the shape presented here. I then redrew the wing plan with familiar tapered outer panels. Not exactly scale, sort of cartoon scale. Thus the 'One 70 Toon.'

The One 70 Toon is simple and easy to build. Light weight contributes to excellent flight performance so I chose 2.2 gram servos, a 4 gram receiver and 6 gram ESC. It is powered by the popular 18-11 2000 kV 10 gram motor. With a 370 2S battery and 5030 prop it draws 14W providing plenty of power.

The Littlest Stick was never intended to be a trainer, likewise, One 70 Toon is a bit too fast and responsive for a beginner. Construction is easy and quick, the airplane is rugged and durable. Let's build one.

Start construction by cutting out all the parts. I use templates made from photocopies of the parts glued to cereal box cardboard.

With parts in hand, glue all fuselage doublers and 1/8" balsa firewall braces accurately in place on fuselage sides. Make a right and a left side. Next glue the two bulkheads first to one fuselage side, then to the other paying careful attention to alignment. Pull the tail together and glue.

Form the nose gear wire and bind it to it's ply plate using sewing thread and Ca. And install. Pre-drill motor mount holes in the firewall and glue it in place. The fuselage top and bottom are cross grain and can be added, then sand everything smooth.

Make the rudder/fin and elevator/stab, sand a bevel on mating hinge edges and finish sand. Glue the stab and fin to fuselage straight and square as viewed from above and from behind. Spray fuselage, rudder and elevator with two thin coats of lacquer or other clear sealer..."

Update 30/5/2024: Replaced this plan with a clearer copy, thanks to Tom Binkley.

Quote: "Steve, Here is my copy of the original One 70 Toon plan. The original model is still in great shape and still flys well a dozen years on. I didn't mention in the article that mine even has a steerable nose wheel. It is a real attention getter! Tom Binkley"
