Whats wrong with MDS?
The good thing about this hobby is that you have so many choices. Some guys spend big, others not so big....................
Its interesting just watching..................
Spend a little time researching and shopping around and you'll have a model/engine that performs (sometimes better) and with the reliability of the big name brands at 50% of the cost.
I bought an SC .75 for my sons 4*60 (got plenty of shock and horror from other club members). I "wasted" a bit of time on the engine to get it to run right and guess what, its now the best performing glow engine I have, at a 1/3rd of the price of an equivalently rated name brand.
Nothing wrong with the cheapies, if your willing to spend a little time and listen to the guys who KNOW.
