Been flying my UCD for 2 weeks now haveing a blast with it ,,using a MDS 148,,Can you say BLAST OFF out of a hover !!!!!!!I like POWER ),,and it IS way over kill,,going to put my YS91 on it ,,I have found that the 2-56 rods for the ailerons are to week,and the 2-56 on the rudder was a joke,,switched to 4-40 , and fixed the bending a bowing,,With full flapperons using the 2-56 The ailerons were sluggish 4-40 fixed that,,and the 4-40 on the rudder made it solid,I could not get a good flatspin and I got a tip from (on on the edge ) I now us full down flapps in the inverted spin and it is flat ,I can keep adding power and it will then do a climbing flat spin,,or get the power just right and it stay's in one spot spinning Cool !,,Thanks On The Edge ,,,,,,,Hope everyone has as much fun with theirs as I am with mine.,,
Happy Flying,,
