About this Plan

P-51D Mustang. Radio control scale model WWII fighter. For electric power. Scale is 1/8.

Quote: "While I was flying his own Shoestring (58in span, 3.5 lbs weight), Ivan and I had a chat about how realistic it looked flying around against the sky and the mountains, and we agreed that a single-engined fighter, built to the same standards, would be just the job. So here's mine: a Mustang drawn up to 1/8th scale (55in span and very lightweight at 3.5 lbs) with a minimum structure and a ladder-type fuselage. The motor is a 3536/1100 from George at 4-Max with a 40A SC.

The tail surfaces and wing are as simple as possible, as is the basis of the fuselage. It has lots of formers, sheet covering and planking round the curvy bits, but it does not have retracts, just a strengthened air scoop for belly landing. I'm sure that if you wanted to install an undercarriage, a .40 sized set would be fine. Incidentally, the model has had 45 flights according to my logbook, and the only damage after 45 often less-than-perfect landings is some abrasion to the radiator scoop.

The look of the model lies in the covering and decoration. It can be modified to any mark, from the early Allison-engined Apache, through the similar Merlin Marks with either the flat or Malcolm hoods, or the bubble-hooded later Marks - even the final lightweight version is possible, although the wing didn't have the LE extension. My canopy came from Vortex Vacforms and is a stock item.

Hand launching is relatively easy, even for a solo flier but is clearly much simpler if you have a friend to give the model a push in the right direction. For solo flying I add a few clicks of up elevator for the launch itself (that big radiator scoop is easy to grab hold of) and at full throttle she leaps into the air. Pull the elevator back to neutral and she flies on rails. It really is a joy to fly and looks fantastic in the air in big sweeping manoeuvers.

I've had trouble with spinners. The original plastic one was a complete failure, so I got an alloy one with a backplate. Even this has given trouble, which is why the flying pictures look a bit undressed.

The battery sits just in front of the CG (I get 5 minutes from a 2200 3-cell)."

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.
