I agree. You have to realized that when I used to fly four stroke heli 3D flying was not very well known yet. I used to have some forward speed when I enter a loop or a roll. I have never done these tic toc and such maneuvers. I think as a whole the model helicopters are quite a bit over powered so a four stroke 91 was doing just fine in a 60 size 2 stroke helicopter. Which in today's size is equivalent to a 600 size.

Miniature Aircraft made a production 4 stroke heli many years ago in the 1990's I believe. Anyone have any info on this extinct bird and how she flew?
I think Carey Shurly has had experience with them.

Setup is everything, All my heli's can fly far better than I can pilot them

I saw a Minair 4 stroke on Ebay about a year ago. I forgot the model but it's something like a 1002 or something like that with numbers.

I think it was the forerunner to the Spectra (maybe not).

I was tempted but I asked a local dealer about parts and it seemed like it might be difficult to get spares for so I passed on it. I think it has a YS 1.20 engine if memory serves.
