Model Engine Transistor Ignition

TIM-6 Transistor Ignition

For a while I have been looking around at model engine transistor ignition systems. Wondering what to buy or even just build from a circuit design. The I saw the kit that is available from jerry-howell.com (this is actually: model-engine-plans.com). The ignition systems and parts are actually on their sister site: model-engine-ignition.com. I bought a … Read more

Making a Wooden Propeller

Propeller on 5 cylinder rotary engine

In particular, making a wooden propeller for the five cylinder rotary engine. I made a simple propeller using 5 different layers, 3 layers of walnut and 2 layers of plywood. So actually more than 5 layers. The propeller was drawn out very simply in form and then I copied the outline 5 times and on … Read more

The Alula by Dream Flight

The Alula by Dream Flight

The Alula by Dream Flight was written by Dave Taylor in 2007, a blast from the past. It’s true! Great things do come in small packages. The Alula – a small glider from Michael Richter. I had read a couple of articles about this kit and was quite keen to have one. I ordered mine … Read more

The Rotary Engine

five cylinder rotary engine

This short video clearly shows the relationship between crankshaft, conrods and cylinders for the rotary engine. In rotary engines the crankcase rotates with the propeller. The conrods rotate about the crank pin. These two rotational axes are parallel and half the length of the stroke apart. In this way the early engines removed the need … Read more

Sketches to Models to CAD

five cylinder rotary engine

I often work backwards, going from Sketches to Models to CAD. However, it works for me as it allows me to create something in the workshop. Sometimes I think this works really well and I think a good example is the five cylinder rotary engine. The only sketch I have of the engine before making … Read more
