The point that I made or was trying to make was that when choosing an engine, it is not always about which has more performance? The OP asked if the engine was any good... and got answers that it wasn't based on power comparisons with a DLE-35. My answer was that it was good based on my experience with the engine, and that it had fulfilled my needs to a tee. In fact, I've only had one model engine that wasn't any good for me, that was a YS-120 and others no doubt loved the engine.
I'm somewhat left wondering why DLE-35 came into the the thread discussion, though I do understand that the 33 isn't any good for some pilots, because there was something else with the same weight and more power.
This is a subject that most don't understand. Engines come in two varieties, torque and speed. When I see a "kid" running down the road in a lowered and "glasspacked" Honda, revving the crap out of it with, right behind him, a guy in a raised truck with a loping bigblock, I just shake my head. Neither one of them realize that the way they are using their engine is going to destroy it.
Aircraft engines are the same way. Running a speed engine with too much prop/load or a torque engine too little prop/load will damage or destroy it
