I have not seen the Intruder yet but have had 4 WM planes in the past and all of them were very good quality with the exception of the larger Extra 300 ARF. I have been eyeballing the Intruder myself and will get the plane as soon as I get some of my other projects out of the way. The Chipmunk has been my favorite WM planes and I really like the flight characteristics, so the Intruder should be the smooth flyer you are looking for...the price sure does help also. I have the Zen 90 with a YS 140 for power and it is very nice...very straight and clean aerobatics, the 140 is grossly to much power but it was all I had
I bet the YS 110 will be very strong and give all the vertical needed. Keep us informed and some pics would sure be appreciated thru the building phase.
