Have had their larger Extra 300S since last year and now flying their Sukhoi. The overall quality is absolutely one of the best I have seen as these are made from laser cut parts. Both are excellent aerobatic airplanes and do 3-D with ease with my YS 91. The wings are similar to what EZ used to make, reinforced foam core with a hard multilayer skin and covering and flies fast and flutterfree even with larger engines. An initial concern was with the covering as it was not a cote but a similar plastic film. However the covering has held up better than my experience with cotes as it has remained wrinkle free and well stuck after more than a year of use and misuse in the hot CA sun.

On the negative side the paint quality on the Sukhoi's tail fairing was not very good and it tended to peel off, however I fixed it with spraying some lustercote on it.

Customer service has been excellent as they replied promptly to my emails within hours.

Both these airplanes are built very tough, the gluing is very good and the airframes are not flimsy and minimal as we see in so many ARFs. They use rugged aluminum landing gear and all the hardware supplied with the airplane is either Dubro or Sullivan. The weight may be a little on the higher side of most ARFs. So flying takes a little getting used to expecially if you have been flying a lightweight. But once you get a feel for them and learn not to throw the throttle stick all the way down to idle when coming in, they are one of the best flying airplanes I have seen.
