Quote: "Hi Steve, I have this plan in my collection, but I couldn’t find it on your site: Funstar by Frederick E Burnham. It was distributed with Radio Modeller Issue 11 Volume 32 (November 1997). I don’t have an article. The plan I’m attaching here is the same model, but the plan's layout is a bit different so probably it has been published in a different magazine as well. Groeten,
Alfred"

QUote: "All the way from OZ, Fred Burman plays a variation on a theme. Funstar Fun Fly.

One of the great things about our hobby is the choice of various types of models for different purposes that we have available to us. Depending on our mood or the weather on the day, we may choose to fly an aerobatic, scale, sport or other type . Some days I don't feel like dragging out one of my larger models and all it's associated equipment and would prefer a model that is easy to carry and quick to set up at the field. This equates to a model small enough to go in the trunk of my car (a small one) in one piece i.e. no rigging up at the field. I like the versatility of a fun fly type of aircraft which you can hot dog or just cruise around at low speed for some relaxed flying, These considerations led to the basic configuration of the Funstar.

Practical considerations: The usual Fun Fly type of layout with a stick fuselage and the receiver, battery and servos in the wing is to me not ideal, in that access to the radio gear and linkage of servos to engine, elevator and rudder can be a problem. I prefer a conventional rugged two wheel undercarriage rather than the flimsy one wheel type often used.

The Funstar is designed to avoid these disadvantages, as well as giving good performance with lower powered 25's and is simple and economical to build. The servos, radio gear and tank are installed in the fuselage, are easily accessible and control linkages are simple and direct. The undercarriage is strong enough for rough landings, which seem to happen fairly often with me. All up I am very pleased with the performance and general simplicity of using the Funstar.

Start construction by building the fuselage because this will need to be finished before the wing can be made. Cut the fuselage sides, engine bearer, Ft F2, throttle servo mount and u/c parts accurately out of the ply thicknesses nominated, to ensure a good fit. Glue the uic parts together and glue the tail booms, tapered as shown, to the fuselage sides keeping these flush with the booms on the inside and laid flat on the building surface. When set, make a trial dry assembly of the fuselage parts. If all is well then glue these together with clamps across the fuselage sides until the glue sets (epoxy recommended). The fuselage is self aligning but the bottom rear section is flat and this should be laid on a building surface and weighted down to ensure proper alignment, until the glue is fully set. Lastly, glue in the servo rails and throttle servo mount.

Having completed the basic fuselage, cut out a set of parts for the wing. The ribs are all the same shape but note the different thicknesses. The wing is built flat on the building board, starting by laying the lower spar in position on the plan, then adding the ribs, using the fuselage as a spacer for ribs W6 & W7. Fit the spar webs between the ribs then add the top spar, the slightly chamfered TE strip, top TE sheet and LE sheet. The LE sheet should finish slightly past the front edges of the ribs to allow it to be sanded back flush with the ribs later, and the LE sheet continues in one piece from W1 to W12..."
