The CDI ignition is only 3.4 oz. and looks to be quite a bit smaller than the Rcexcel units for CM-6 plugs.
The info regarding the bushed conrod is incorrect. On another forum, two reps from HH jumped in and explained that it was a production change, and that the engine will have German needle bearings on the conrod, they're also testing with less oil in the gas as well The carby is not pumped, just regulated. The manual shows muffler pressure being used to the tank vent line.
I look forward to seeing some reviews of this engine.

Just realized I had an RCexcel for CM-6 on the bench, 3.6oz. not much of a savings[&o]
