Of this particular brand, only the one. As for other brands in various sizes, I have a lot of experience "hands on". What you don't, or need, to know is that I do some interesting things for a living that involves gas 2 strokes. Also withheld from the public is that the person I bought from agreed that the damage was likely caused by poor packaing at the point of origin, and there was no objection to my manner of correcting. So I did not "jump over the distributor". You also don't know the total timeline fo the cummunication chain, or all that transpired within it.

My comments in the review were and are specifically directed at the 100 twin. They make what has been reported to be a pretty nice 50. The Peak 65 is essentially their engine as well. The 100 in the version I received would not last a season for an average flyer. A new version is soon to be released that's said to incorporate quite a few improvements. I'm a chronic doubter so I'll wait and see before saying a word.

You folks didn't pay for the engine, I did. Quite a bit in fact. I provided a lot of free R&D info to them before the engine was first run, balked at doing more for free after paying for the engine, but in some areas I'm still relating critical info about improvements. At the moment I'm going out of pocket further to repair the engine and seek ways to improve it. That info will be passed on to the appropriate people. I'm in no way required or obligated to provide everyone all the behind the scenes communications, of which there was quite a bit, and which still continue.

If someone wanted me to sell an unproven product, they normally would send me that product at their expense, not mine. If I knew nothing about those people first hand (I did not) I would make it a point, as I did here, to determine that all I had been told was true before climbing on board. I provided all that was needed for someone to make an informed purchase decision based upon experience from a product quality and consumer position, not an extremely biased sellers position. Had the product not already been made available for purchase to the general public there would have been no review, just behind the scenes communications for product improvement purposes. The fact that the engine was and is for sale on the open market, and light advertising was being done through an engine thread, opened the door for an honest and critical evaluation. What people do with it from there is up to them.

I'm starting to think that people have gotten so used to favorably glowing product reviews that they think everything is peachy wherever they look. That's not the way things are. Many reviews are written by people that get a lot of free stuff as long as they write favorably. They don't want their new and free product supply cut off with a negative word, so they don't tell the truth. Ever wonder why almost all the new kit reviews in M.A.N. are all written by the same person?
