I've had the pulse 40 xt and just finishing building the 6o size version, The .40 size was great. A the field I would get to only fly it once or twice then the other guys would take over and fly it and land it. Allot of them say it compares to Gp Super Sportster. I love mine. as matter of fact I have an offer of 150.00 to sell it. Will most likely sell it to my buddy. I have mounted the new .61 NX evolution blue head to my new 60 size pulse. Very nice airplane. Will make a nice addition to my fleet.
