Give Hobbywing a shot, They are a GREAT following with GREAT things to say about them. The Quality is there Regardless what some Tekin,LRP, or Novak Nuthuggers say. They are very smooth have just as many adjustments as the others and a very fair price tag, all with a low return rate as far as defects and such. I ran a XERUN 150a before and LOVED it! They have come a Long way since i ran one and would not hesitate 2 seconds to purchase another!
