I've never used an MSC. The comparison was written by Patrick Roy. He works with the UAVs and knows a lot about the subject. If I were you I would buy a Vess 22B or 23A and run it but that's just my preference. He compares a 23A Vess against a bunch of 22X8 props and not on this engine. My 23A gets 7400rpm and a ton of thrust so it's not overloading this engine. The props I wouldn't buy are the TBM or a Zinger. I'm quite surprised your Xoar broke. Did you have the Beechwood ply prop that I use or the solid wood? The ply props are really resilient. You may want to get some second opinions on the MSC props from someone who has used them. Bubbagates or JrJohn may have used them in the past. Anybody want to jump in on this???
