After many years of procrastinating I'm finally building a Phase 5. Designed in 1978 this model is often considered to be Chris Foss's (CF) best slope model. It was never available as a kit so the only way to get one is to build it yourself. CF is still selling the plans if you fancy one.
The Phase 5 plan calls for a built up wing but I'm deviating from the plan and making one from foam with a balsa skin. A snow day today meant I could make a start. CF does not specify what sections are used for the root or the tip so a bit of guesswork and internet trawling resulted in the semi-symmetrical E374 for the root, modified a little to make it thinner. The tip is fully symmetrical and is between NACA 0010 and 0011. It's actually 10.67% thick so maybe it's NACA 0010.67?

If you have read the previous article on the Wots Wot you will have read that this was the electric version. The basic model comes without any mounting kit. You select the which kit you wish to use, i.e.; electric or glow. In the previous article I built my Wots Wot for electric using a SK3 5045, 660 kV motor. The plane flew very nicely but I needed a that size motor for another project, and as much as I hate to "cannibalise" working models the motor had to come out. not wanting a machine that does not fly I decided that a biplane such as this really needs a nice four stroke glow. The following article describes the conversion back to glow, the opposite to what many do nowadays.
