How fast would a fourstroke powered plane go? There are sound emission restrictions on our field, and I don't want to go electric. I want to spend about 400 euro on a plane.

400 []

A half decent engine like the YS 110 is going to cost around 350... that leaves 50 for the plane... you can get a servo for that...
Even the cheapest four strokes around are still going to cost around 150... that leaves 250 for the plane... still not enough...

Start saving money...

ok, engine not counted with that 400

So I need a pumped engine?

Of course you don't.

But the Yamada's are simple the most powerful four strokes available... power in a small package... that's what you need for speed. They come at a price though...

Do you have a engine already?

I only have a OS fs 40 surpass. I was thinking about a Magnum R or that delta.

BTW do you know Tom Verstappen?

Tigershark with Saito 100?

give a magnum R to a os 40 surpass is give caviar to a pig !!! I am used to noise restrictions, tell me what noise you are allowed to do and I will tell you what engine for Ã* magnum R

No, not my OS in the Tigershark, but a saito 100.

a saito 100 in a magnum is a too heavy engine for those small wings !

and I KNOW tom verstapen !!!!!!

I have been in contact with him when he was collecting infos about spit

79 Db for a fourstroke.

this combo is in the noise restrictions you call

my whip

by the way the four stroke are not so "quiet" regarding 2 strokes (with standard mufflers) the noise is different, it seems to be quieter, but is not
