About this Plan

The '55 Rambler. Control line team racer model.

Quote: "Better than even his 1954 Nationals winner, the '55 design consistently has broken the 'eight-minute barrier.' A 'snow job' isn't necessary for this team racer. A word tells the story: performance. TR chariots in your blood? Do try this one. The '55 Rambler, by George Moir.

Team racing officials are becoming more conscious of the design and appearance of the models: beauty judging is becoming an important factor in the team race event, as the planes have been getting faster and faster, for it is in a close race that beauty points may mean the difference between being chosen for the feature race and being barred from it. So, with this in mind, I designed this new Rambler, which has a snappy appearance and is very easy to build and has proved to be a strongly constructed plane, as well as a very steady flier with plenty of zip.

This model design has already twice broken the eight minute barrier: at Frederick, Md, 7:57; at Washington Contest in Rockville, Md, 7:59, both times taking off from rough grass. Speed averages about 5 mph better than the '54 Nats winner, delivering from 90 to 104 mph with an MS Fox .29 up front.

Acceleration averages 2:6 to 2:9. At Far Hills, we checked in at 2:2, 18:5 in the seven laps. A sister ship owned by Bob Hemingway also checked at 2:7 to 19:00 in the air. Bob is the fellow who twice did under eight minutes with his Rambler and MS Fox set-up. Bob is 15 years old, which proves you don't have to be an old pro to build this New Rambler.

As always, study drawings carefully; save many mistakes later.

Make up formers 2, 3, 3A. 4, 5, 6. Tail-wedge form-ers 4, 5, 6 are two pieces of laminated 1/32 hard balsa. Formers 3, 3A are laminated medium hard 1/16 balsa. No.2 is 1/16 plywood.

Cut out 1/16 plywood doublers (two), mark off thrust-line (TL) on doublers and also all former positions. Mark the doublers where formers 2, 3 go. Cut motor mounts (MM) from maple or some other tough wood that won't splinter easily. Cement MM to doubler on TL's. Cement formers, 2, 3 in place. You now have a box-type section; keep this square while cement dries.

Cut out two side planks 1116 x 17 medium hard balsa. Mark off on inside of planks the positions of all the formers; remember the top edge of this plank is your TL. Cement side plank to front section (doublers) lining up top edge of plank with bottom edge of MM. This is a very important step. Cement all formers in proper place, lining up TL with top of side plank, except 3A, which is installed after wing is in place.

Cut out wing from 3/8 x 28 medium hard balsa. In-side wing panel is 1-1/4 in longer than outer wing. This is a feature that helps make this plane stay where pilot wants it, even in heavy winds. Gouge out two 1/8 slots for lead-in wires; also, gouge out for bellcrank (BC) movements, BC to be installed later.

Lay 3/32 wire in wing slots, then cement 1/8 balsa strips in slots. Make sure you have movement on wires so they can be removed, leaving a hole for regular flexible lead wire to be installed later.

Cover wing with nylon for added strength. First cover the center area 5 in on each side of center line of wing. Sand edges down, then cover wing all over with second piece of nylon. Install wing in proper position, exact right angles to fuselage center line..."

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.
