inquiry, can someone teach me, thank you!

Hello Mauricio. The builder was Tim Wiltse. Brilliant work(imho). I have
one of his engines, and some parts he modified. His anodizing was perfect.
Regarding the Mangusta:
Price is relative. Look at the number of bidders! The BIG question is, how
deep are your pockets$? Too rich for me.

Hello, thank you for the answers, but as I said before, I would like to learn and it is precisely because I am at the other end of the world and I have no knowledge, I can only read them to you or whoever puts accurate information and from there he has learned something new.
Maybe I was not clear enough in my question, so now I will ask the question differently:
What does Mangusta mean?
Who is Mr. Tim Wiltse?
What technical data does this motor show in operation?
RPM:
Weight:
Propeller:
Fuel and proportions ??
Type of glow plug?
It says that the cylinder is chrome, is it really chrome (chrome application) or is it exterior polished?
Applying chrome to parts is a very different matter than a bright polish.
So now, maybe it will be better understood what I want to learn ...
Brad, my friend, I read the entire description of the item and that description caused all these questions to me.
David, the anodizing process is an interesting topic for me, I would like to do it sometime, but on this engine I was not attracted to those "graffiti" colored details, I still prefer the full intense colors and not as shown in the tank on this engine, but those are personal taste.
I hope I have clarified my doubts. It is not about mistrust, I just hope I have clarified my doubts to learn.

Bob, there I could see details of one of your engines, where the transfers and interior channels have been reviewed, I also see that the piston was modified, so there is precisely a reprocessing of the parts.

It would be interesting then to know data of operating results with measurements of rpm, etc. etc to have knowledge between an original engine and an engine prepared by this Mr.

Wel as y say it look prety just To m'y opinion the tee dee .051 for price compare To those engine y tink the run  bether just saying y tink the mangusta get bether wit time of use truly dont no m'y tee dee run Good first !wy no result rpm test statique y use 6x3 Most of the time and get decent run so if ther la no result go figur

To me it looks like a custom collectible engine. I doubt it will run any better than any other engine with similar configuration. The lightened piston does make me curious though.

It looks pretty, but for that kind of price I’d expect a NOS backplate, not a modified used non-stunt version. This would look great with one of those new aluminium backplates, by the way

I agree that the price is ”right” when the deal is done, I just hope the buyer knows what he is buying. This engine is rare and unique just like any other custom engine. The price depends not so much on what it actually is, but on who did it. Just like any other form of art. Performance does not matter much, as it is not expected to be mounted on a plane... So it may have all the right parts and a modified piston, but I am 99,5% sure that whoever buys it won’t run it.

Yes, I think it’s pretty. Would I buy it? No. But to each his own.
