Hey CSI. Welcome to the family.
Has been a bit quiet on the thread. Guess we are too busy, out flying the coverings off the Leader
The mods you suggested are fine ifyou feel required. I did add the extra magenet to canopy hatch, though had no bad experience. Extra CA around the joints is a good precaution. My Leader has about 100 flights on it without issue.
The rudder authority though not massive is adequate. I can hold a reasonable knife edge pass, though need to maintain some speed.
I run the Power 10 and 11x7 and find this the best power mix for me.
