RE: Saito 82 uneven running on large props
HS,
The OS (and clones), the Enya and, of course the Laser, will run well on 5% nitro.
The Saito (and for sure the YS) wouldn't.
If you're already at it, just get the 15% nitro fuel; not the 10%, which is on the very edge...
It wouldn't be that much more expensive; even in the UK.
