I can’t comment on the Proteus as I haven’t owner one.

The Ascent has been around for a while and most that I’ve seen fly are more than competent but ridiculously expensive.

I’ve had 3 Alchemy mono planes that are the sweetest flying f3a planes I’ve ever owned. The only mixing I have is the usual vertical down line throttle off tiny bit of down elevator. Bryan’s planes look fabulous and the finish is as good any.

There are also some great assembly threads by Jason Arnold of https://www.precisionaeroproducts.com.au/ that over the Alchemy build and shortly there will be one for the Alchemy Bipe.

I’ve ordered the Alchemy Bipe and look forward to flying it Andre-outing on it soon.

in short, I’m an Alchemy fan
