Hi Tony,
Where did you see this speculation and contradictory figures?

When I was following D-Motor development a couple of years ago they seemed to be an unusually open and honest organization - admitting where pre production engines did not meet power expectations and discussing how they intended to overcome this and other development hiccups.

Some of their engine development decisions seem a bit strange when viewed from the outside - no bed mounting to make the engine an otherwise perfect replacement for the Rotax 582's; diverting effort to the development of the six cylinder engine before getting the 4 cylinder into full production. - I'm guessing there will be some teething problems so getting these sorted ASAP so they could be incorporated into the 6 cylinder design from day 1 would make sense to me.

No doubt there are good business reasons for the path they have chosen - (development grants, market opportunities or whatever).

I watch with interest.

Cheers

Bob P
