16 May 99 - I purchased this kit at the Sandown show on 9 May 99. It was designed for electric power, but also includes all the necessary additional parts to build for i.c. power (0.15 to 0.18 cu. in. motor). The kit includes all the wood, fairings, canopy, pilot, hardware, decals and plan. Additional it has what appears to be the most comprehensive instruction manual I have ever seen. They recommend the use of 3 mini servos, but I will be using 2 micro servos for the ailerons instead of 1 mini servo. I find this much easier to set-up and gives much more precise control.

13 Nov 99 - I have just received the Robart micro retracts for the model and started thinking about the modifications required to fit them.
