I am just getting back into pattern flying and I enjoyed designing and building my own in the past.
I was just wandering what the width of the modern pattern plane fuselage is.
Are we talking 5 inches or more?
For instance how wide is a Synergy or the like?


Thanks
Katipo

All I have at home right now it a Majestic. The fuse width at the front of the wing saddle was 6.5". The Synergy is going to be in that neighborhood too but I'll get an exact figure tomorrow in the factory.

In another thread about 60 size pattern, I expressed an intention to purchase CA Models' Widebody 60. The CA Widebody series have very narrow fuselages, perhaps to reduce form drag. My question is, what's the downside of a tall, narrow fuselage, in terms of flight characteristics?

Thanks in advance,

Marc

The width of my Hydeout is about 5 inches and the width of my Silhouette that I'm building now is right at 6 inches (at the wing saddle). Here is the link for the Silhouette if you are interested...

My new design Mantis EX is just about 6" wide at the leading edge of the wing.

What airfoil did you use?

Thanks
Katipo

Basically, it is my own airfoil improved after many years in pattern .

It is 11.5% at the root and 12% at the tip. Profile is somewhat very close to ZN Line Evolis wing when I compare. The main differences are, it is a little thinner at leading edge and getting almost flat towards the trailing edge (I've got the idea from Chip's Hydeaway "Reflex" profile and it worked well).

Wing area is fairly small, less than 950 sq.in. It has very good performance in snap rolls.

Hi Marc
Re your 2ndary Question
I guess that when your plane is on its side and the fuselage acts as a wing then the difference is like the difference between thin and medium thickness wing sections. Better lift and a lower stall speed at higher angels of attack.

Thank you for that Nedim

I had a quick look at the RAF30 but need to find some more data on it.
Where can I get some info on common pattern airfoils?
I would like to use Profili to draw the ribs, so I need to source some current airfoils to compare.

Cheers
Katipo

I can measure my foam cutting templates with a vernier caliper and send you the values if you like.

Thanks,
Nedim

If you would be so kind, that would be great.
Thanks
