I thought I’d take a break from designing gliders and build a (powered) vintage classic along the lines of the Junior 60, something light and slow but 4-channel rather than 3.
I found a plan for the 4 channel Super 60 but it’s boxy fuselage shape and angular fin just didn’t ‘do it’ for me so I started wading through the Outerzone plans website. I found the 4 channel PD Parasol and got quite excited about it! But, although it’s tail shapes looked beautiful, its fuselage shape (convex top and bottom) was not my (pre-conceived) idea of a vintage classic. Then I found the lovely curvy fuselage outlines of the Deacon and the Viking and the lovely wing shapes of the Dot I, and Black Magic.
There were quite a few 3 channel designs that I really liked the look of but my heart was set on having aileron control for some slow, low-energy, aerobatics with half-decent rolls. An aerobatic vintage design called the Over & Under caught my attention but I couldn’t see any way that its fully symmetrical section would give a low sink rate when compared to the flat bottomed Super 60 or the semi-symmetrical PD Parasol. I almost decided to just build a PD Parasol exactly as per plan but I definitely didn’t want a one-piece model and I couldn’t visualise an attractive and lightweight way of adapting the parasol and struts to a banded-on wing. I also want something slightly bigger than 60”.
So, I embarked on producing a new vintage-hybrid design along these lines:
Semi-symmetrical wing section of the PD Parasol with strip ailerons as per the Super 60.
Curvey fuselage of the Deacon/Cardinal but a little extra nose length and diagonal bracing.
Tail feathers copied directly from the PD Parasol which to me look perfect.
Wing shape similar to Black Magic.
Approx. 10” chord, 70” wingspan, 40” fuselage.
Electric power (I found the 4-max website. What a great resource!)
Out of respect for Roger Jones’s RCM&E Forum comment “designing your own ‘vintage’ model is a bit phoney”, I decided to call her the ‘Old Phoney’.
Buying the servos, there was a special offer on five. That got me thinking “what could I use the 5th servo for?” then the penny dropped – a tow release.
The plans are still being tweaked but here’s a recent version:
Inspired by Cliff Harvey’s videos on YouTube, I started by laminating the wing tips and tail:
Then found an old bit of 3mm ali for the u/c:
