I have two of them and will by a third this winter. Once I learned how to set up the Mixture servo curve properly the second setup was easy. With the MC carb I can adjust the mixture in flight witch works great.

Im flying the Ultra RC Evelutiion With the Webra 160. Currently building the Focus II with the same engine. I fly with 2 other guys who have the same setup. Dale Aronald has been winning with ths setup. I have done well in the last 3 contest.

I run the APC 17x12 Dale uses the APC 18.1x10
Muller custom header and ES tuned pipe. I run 10 % cool power , Dale runs 20% with 2 head shims.
