I am trying to decide which engine to use on an AW 33% Extra ARF.

I am interested in the ZDZ 100 with KS cannisters especially, and either the 3W 100 or DA100 with cannisters.

I have had very good experiences with ZDZ's. I fly a H9 Sukhoi with a 3W100 with in cowl mufflers and its awesome power wise but noisy. I know the DA100 is good also.

Mostly interested in info on all these with cannisters. How well do they carburate, etc. I also would like to know header length requirements. I have heard comments the ZDZ needs cans to perform well.

All answers appreciated.

Jeff
