G'day

Way back in 1992 I put an OS 48 Surpass in a Thunder Tiger 40 size trainer. All the experts told me it would not work but when they flew the plane, they were immediately converted.

Four strokes will happily run at part throttle all day, are economical and best of all, quiet. They are not hard to handle and rarely deadstick. As a result, I have been using them in trainers ever since. They are particularly good for older learners who seem to appreciate their good pulling power at lower speeds.

They can be damaged more in crashes than two strokes but I have always been able to repair them and with buddy boxes, crashes are rare these days.

At the present time I have a range of trainers and only one has a two stroke.
