RE: evolution 58 or DA-50 ??
Two in our field using DA-50s.
Light engine (that plane is nose heavy), plenty of power and a nice choice of muffling solutions.
The planes at my field are using the Kaleo scall scale exhaust and it looks and sounds great.
The Evo 58 is larger, heavier and does not have the multiitude of third-party solutions you can find for the DAs.
Now, if you care about the price, the DL-50 will provide you about the same performance with a marginal weight increase, same size and can use all the peripherals the DA uses.
If you want more power in the same small package, the BME 58 might be a solution. It does suffer from a lack of tird-party accessories ,much like the Evolution does.
