I have heard the complaints about the tail on the Pulse and I have one..Hanger 9 did address the problem..It does have big tail feathers...What I did was glue them in place perminantly...If you dont they wiggle a bit...If you ever had to replace them you could still get them out...Also putting flying wires on is a huge help.. The pulse is not ment to be a high speed areobat..It is more of a relaxing sunday flyer..If you overpower it and do high speed dives and such you might run into trouble but I have not had any problems whatsoever and I am running a OS 120 on mine...I really like the plane....
