The Quad Chip with the 34hp will be produced until we either hit 2020 or run out ofthose engines. We then will have sorted out possibly 37hp petrol and 26hp diesel if that's what people will have.

Will you use the flywheel from the Evo 165 on the quad chip with the 26hp diesel.

Dunno. That's a major redesign and would more than likely push us way past 750kg! Doubt it to be honest....

Its more in the design of the heavier flywheel than just a heavy flywheel.

Take the 8" petrol Bearcat petrol chipper for example (or any of the larger Bearcat chippers).

Massive flywheel, supposed to be a 8" capacity, 20hp petrol engine. Relies on the flywheel inertia to keep going. End result is feed it more than  4" branch and once the  flywheel slows down it takes about three days to get back up to speed. There is obviously parameters and a carefully calculated engine hp / torque, pulley gearing size and flywheel weight to get right.  

agreed,  said Bearcat was available with a 20 or 25HP petrol enjun and a 28 or 48HP diesel enjun.  basically all the same machines apart from the power unit and pulleys.  I ran a 25HP petrol one for over 2 years and it was a bit tiresome to use on anything over 4'' in diameter especially as my one didn't have a stress control fitted as this was an optional extra when it was new.  Having said that they are very easy to work on and i sold it on for £500 more than i originally paid for it.  I did buy a diesel one too but it needed a lot of work so i sold it to a mate as i wanted shot of it!

Build quality wise not really much wrong with them but not a chipper for a tree surgeon.
