Mine is 2.5 years old and I had to replace stock motor to due bearing noise to due nose in crash
Hehe...replaced with smaller but little faster E-flite Park 480 and has run great. I use it with MAS 3-blade prop and now it loves to go vertical. A step or two slower than stock prop but worth it for me.
There are at least 4 members of our club with T-28's and we love to form a squadron from time and time and try to fly together...what a hoot!
