2.47cc. Nice airbleed carb and quiet silencer. The same physical size as the OS .15.

4.04cc. Nice 6mm venturi carb and silencer. A very light engine popular for Control Line.

"This is a very good value for money engine. If run in carefully as stated in the excellent instructions supplied with the engine, it will last a very long time. Its proved very easy to start, usually within 3 flicks from hot or cold once primed. With a very easy to tune carb, it holds its settings very well. "

5.95cc. Thousands sold in the UK over the last 5 years. Leo`s most popular engine. Supplied with quiet silencer.

Leo .37 RPM supplied with J'EN TN2 8mm carb, use when highest rpm is required for fast sportsters and even faster deltas only £5 extra.

"From the first flick of the propeller it was apparent that this engine felt ‘right’, even from new it bounced over top dead centre freely, certainly not always the case with ABC engines. As expected the Leo started immediately by hand and ran smoothly."

7.50cc. Very light .46 copied from the O.S.SF series. Not the most powerful .46 but ideal for trainers and sport models or sport Control Line. Supplied with quiet silencer.

"The Leo 46 EP ABC is of good all round quality. Had I not been told it was a budget engine, I would not have known. On strip down, there was no wear whatsoever, even after 6 hours running. It offered excellent throttle response with a very good reliable tick over. My opinion: money well spent."
