I went from Lt-40 to Sig SE.....fun aint it..now

Check you engine thrust...if you have too much down thrust..then you will have trimmed the plane at speed, elevator up..( to check, get some altitude..at 3/4 throttle hands off level flight...throttle down just above stall speed, does it noes up?? if it does then the engine is pulling the planes attitude down..so when you slow to land..the nose pitchs up and it will sail on you.. just a thought
