I am going to order a Sceadu 50 and I was wondering what % nitro fuel is everyone running in the OS 50? Is 30% really needed for this bird? From most of the posts I have read the Sceadu 50 is a rocket and most people don't even run 100% on the top end of the throttle curve. I guess what I am asking is if I run 15% will the Sceadu 50 still be a rocket?

I’m using 10% nitro and there is enough power. I could say a lot of power (it is still a rocket). I can say you that I've used also 16% and I didn't find difference. I have not tested with 30%.

Marty,
I am running 15% on the os 50. It has a great deal of power. Plenty for whatever you would like to do. The 30% would give more but your flight times will be shortened when compared to the 15%.

15%
I run 15%, but some fellow flyers have been using 22.5% (15 and 30 mixed 50/50) and that seems to work REAL nice.
I am going to mix up a tank next week to try.

Most of the 50's around here run on 10% with good power

I got two Sceadus50:

1.
OS50
Hatori 3D
15%Nitro
SAB600
+12°/90%throttle
1950rpm

Hi all
OK this is a real rocket, but!

2.
Webra52
Weston UK Genesis Pro Pipe
15%Nitro
SAB600(Will change to NHP600 Razor pro)
+13°
1950rpm

Unfortunately i don't know a word which is faster than a Rocket,
Lets say a super Rocket.

The Webra52 is much more sensitive to adjust the carb correctly. I did this with a friend, because i just couldn't get it to run as it should. But know it's super smooth AND even more quiet than the OS50 with Hatori.

Kind regards
Martin
