Thanks Mike, whilst I do not know a great deal about tug engines I thought the main advantage of such engines was the ability to be maintained by non LAME labour, lower consumption and the ability to descent rapidly due to water cooling. Not sure if it outweighs the problems you have mentioned. Reading their website it would seem that the kit had an approval, but I do not really know.
