Once I made contact with the MVVS engine manufacturer in the Czech Republic and they gave me an exemplary service, from there, I learned much more about that place on earth.

This time it is about another engine from those parts of the planet, but from the MP Jet brand, so I want to share it here since I have not seen many videos that show the MP Jet .061 R/C engine in flight.
It is an engine with excellent performance and admirable power.
In the video it is a very windy day, but the engine defended itself perfectly.
I hope you like the video. Thank you !!

Thanks guys! ... this engine really packs a lot of power ... I'm looking forward to doing something special for it.
A very powerful engine for its displacement! Shocked

Another gem from Mauricio!

You must have marvelous eyesight, I kept losing it in the clouds. Got a grin from the applause and thumbs up at the end. Great sounding little engine.

Thank you all for watching the video and commenting on your opinions. cheers cheers
Ohhh the view !! ... I can still see quite well but with the help of glasses. I've already lost part of my vision, but I can still make out the fast turns in the distance ... just in case if you come to visit me one day, wear a helmet! haha...
Friends, a pleasure to share here with you.
As soon as I can, I will start working on a project for this engine.
Please, take care of everything you can, here in my city, the Covid is already reaching many people ... I hope to stay in these conditions, but without social gatherings and with all the safety elements at work. Still, the risks are present.

Well friends, I think the engine deserves a better day, and today the opportunity was given.
Take an hour and I wanted to film the flight with this clear sky, the wind does not interfere with the sound of the engine, so I hope that now you can see the model better and hear the engine all the time. Very Happy

What experience do you have with .074 Norvel?
I was looking at the performance of the MP-JET .061 r / c and wondering if it is comparable to Norvel's .074 r / c?

If anyone on the forum has measurements and experience with the Norvel .074, I'd like to know what they think.
If you have any video, even better.
It is a very light engine, low weight from what I can see beforehand, and apparently very powerful, but I have no experience with the Norvel .074. Huh... Huh... Huh...

Here is a video of one from Combatpigg. He seems to have quit flying recently. Mine is barely broken in, and really does not start well in cold weather. The sleeve seems to shrink down on the piston making it hard to start. Once running it is nice handling overall and is fine in the summer. https://www.youtube.com/watch?v=Wq9vd5ja-gw

Haha, yes, been there done that... Laughing
It took me about one season before the Norvel .074 would free up enough to not need any preheating of the cylinder in the typical weather we have here.

Once broken in they are indeed great engines with an impressive power to weight ratio. Here is one of my old videos of the Norvel .074 engine, inverted and fully cowled in a Super Chipmunk:
