I thought long and hard about the power plant Topflite recommend 40cc-70cc petrol or same power glow, I really fancied a radial but the budget would not stretch that far so a 65cc RCGK from Al's hobbies was ordered.
The 50cc RCGK used in my Corsair has proved reliable to date so at £170 its worth a risk I purchased a Pitts muffler for a further £50 and all arrived in two days. The spec is;
