mine flew and flew GREAT!!!!! the mag 52XLS is plenty...almost to much with full throttle level flight. It was VERY windy today, 15 to 25 gusting... this plane is dam near IMPOSSIBLE to land with that much wind!!! you really have to take your time and just let it quit flying on it's own...trouble is the plane does not want to quit flying!!! even at 2300 rpm idle it was holding alt in the wind. snap's are VIOLENT with MAX throws, roll rate is blinding with max throws and loops are TIGHT inside and out, with MAX ele you have to be careful... it will snap/break out without ele>flap coupling, this plane really needs dual rates for ele unless your easy on the sticks. The plane does and awesome upright and inverted flat spin... inverted was harder to hold in the wind for some reason(ME) up right I could have spun it into the ground from 300ft it will also climb in an upright spin. waterfalls are nice and tight with no loss of alt to speak of... you need MAX throw to make them look right. I didn't try any knife edge... next time. with the CG set at 4 7/8 it's not at all ele sensitive on low or high rate...just make sure on high rate your easy on the ele...to much will make it snap. BTW my low rates were book high... high rate was all I could get, bout 45/50 degrees... my robart throw meter only reads 2 inchs up/down ... I'm getting a little over 3 inches of travel on ele and ail, rudder is about the same, that's more than the recommended 3D throws all in all this is one GREAT flying plane... the only thing I think it needs is 4 stroke power, I'm gona call a few LHS to see if anyone has a saito 72 in stock... this should make the PERFECT 3D/sunday flyer beat around plane

Bearair, I took my 72 off my EF 540 to see how it would fit... the only problem I see is the throttle, I'm thinking at this point I'll use a 2-56 threaded rod in the stock location,bend the rod to 90 degrees and pass it through the throttle arm with a nut on either side... the carb will also be in stock location...I think it will work... if not then it's bell crank time

I just remembered... I flipped the carb on my 72 to make tuning easy on the 540...the carb on my 72 is not in stock location Bearair.
