Da-150 or 3w-150qs

[jdearduff]

I am looking at both of these motors for a 46% ultimate. What do you guys think? I have owned da-100's before and loved them. I had a 3w before and had problems. But everyone loves them. I guess it is the old Chevy or Ford thing. Some guys at the club fly 3W and they seem to have great power. Both engines that I want to buy are used. So tell me what you guys think.

Not everyone loves 3W. DA all the way

I have both a 3w B2f 150 the old version and newer version 150 with the split crankcase. I also have a DA 150. In my humble opinion the 3w have a little more torque and will turn a larger prop, but they take longer to break in, run hotter. 3W have two rings versus one for the DA. The DA has been a consistent flip and fly engine out of the box and has run great from the start. Both engines turn the Mej 32-10 at the same top end numbers.

I"ve seen alot of 3W's with nothing but problems.
Desert Aircraft sells a great product and has second to none customer service.
It's a no brainer.

I have had many 3W's and now have 2 DA's, I will never go back to 3W if I can help it. 3W may have more power but you ever need service DA is second to none. Go DA...
