April 12

Up

Our April 12 event had a smaller crowd:

The turn out was smaller for this event due to the nice weather outside. We shared the free-flight class time with the 3oz and under class. The only other class was the 10oz planes. We still had several new designs seen at this event.

Alex brought a 1 gram free-flight plane and his thrust gauges.

This model was built and flown by Jim Detar. The following information was provided by Jim.

The model is based on an old Walt Mooney peanut scale plan obtained from Peck Polymers.
Span: 13"
Weight: 6 grams
Power: 1 loop of Tan II rubber, .065" wide, 15" long

Some info about the full size Found Brothers "Centennial 100" aircraft can be found here.

Jim also mentioned that the model is "traditional" balsa frame construction with Japanese tissue covering. The prop is hand carved balsa wood (not as hard to do as it sounds!!). Trim is strips of Japanese tissue. Number s are dry transfer "rub on". Finish is a very light coat of Krylon Crystal Clear acrylic spray.

I had my usual fleet with my new bit-charger conversion on the top of the heap.

An N20 Twin was noisy but flew very well.

One of John Gardner's latest bluecore designs is intended to be a "plug-n-play" ARF for the RFFS100 module.

Here is what John writes about it:

Shoe Box Flyer
WS 8"
Chord 3"
Weight 21 g
Motor N20
Prop U80 in pic, but I think the final version will be 2.5X1 GWS
K145
Actuators 2@ 50 ohlms, .5 g
Material: Split F3, 2 and 3 mm thick, with skin on.

That was the concept. A tiny, easy-to-transport, tough little bird. So far it looks good. The actuators did not have enough umph on the 12th. I only used one magnet in each actuator. Since then the magnets have been doubled up and seem quite effective now.

The plane flew fine in terms of power and stability. As soon as we have real flight reports I will post a new thread.

My son is considering building them as ARF's with actuators and motor/prop installed. Just add RFFS and K145 and go.

Another fun indoor event was had by everyone.
