About this Plan
Bambinetta. Free flight sports model for Bambi diesel power. Model Aircraft December 1955. Bambinetta 21 in span F/F, a Ray Malmstrom design.
Quote: "When I lovingly caressed my Bambi diesel for the first time I knew I had to wrap something very special around this minute bundle of power. At the risk of having my head referred to as being rather larger than normal size(!) I think Bambinetta is that 'something.' An all up weight of less than 2 oz ensures that your Bambi won't have to tear its heart out hauling Bambinetta aloft, and there is no fear of bending that precious metal prop on landing.
The fuselage is from medium hard 1/8 sheet thinned to 3/32 at the rear, Cover the cut-out portion with lightweight Modelspan. Cement in position the 1/8 ply engine mount supports, and the rear wing mount Add the pod sides, made from sheet, and round off all edges with fine sand-paper. Complete by adding wing pegs, and give two coats of clear dope after water-stretching the tissue. Fuel-proof the engine mount.
The wings need little explanation. Check for correct polyhedral angles and do be sure your wings are free from warps. Water-stretch and give one coat of clear dope. Fuelproof the three centre panels.
Add the tailplane mount to rear of fuselage. The fin is cut from sheet; note the small trim tab. Tailplane is perfectly conventional, and of simple construction. Give fin and tailplane one coat of thin, clear dope.
Flying Make sure your balance is correct (see plan); original balanced without any weight adjustment, and has packing under leading edge of tailplane, Test glide over long grass. Obtain a reasonably flat glide, without any suspicion of a stall, or turn to the right. Then with your Bambi giving less than full revs, try your first power-on flight. A gentle climbing turn to the left should result. Avoid a sharp left turn by slightly offsetting the fin. Do make all adjustments gradually. On full power, Bambinetta should fly into a left hand climbing circle. When the engine stops, the model should settle into a flat glide with a wide left-hand circuit. Avoid any tendency to turn to the right, which on this type of model can be very dangerous.
Less than 2 oz is not much to battle against half a gale so please fly Bambinetta on calm days! It is my hope that Bambi owners will try this little job, as I feel sure they will get a great deal of fun flying it. I should be delighted to hear from any aerobod who builds Bambinetta. Please write c/c Model Aircraft."

* 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.
