Default Not flying yet but I've done it on RV7

Vert induction io360 parallel valve, three blade CS MT. O320 mount, vans O360 cowl had to graft between 1-2.5 inch on rear of cowl halves (actually 3 inches all round then trimmed back to fit length.

Was originally intending sensi metal 2 blade with future upgrade to 3 blade catto and that was the purpose. MT weighs same as sensi so maybe a tad on the forward side of W&B full fuel no baggage or Pax but won't know for sure until it's weighed.

Vans said no, I signed a waiver, other people had done already at that time or added spacers between engine mount and FW. I'm comfortable with what I'm doing, I wouldn't necessarily recommend it for every builder. It wasn't an insignificant amount of extra work, mostly due to cowl extension. If you could order an extra length or uncut 360 cowl from Vans or aftermarket that would cut down the work. Not sure how it would go with horizontal induction setup. The room behind the engine is much more manageable. I couldn't stomach bolting on dead weight to fix W&B after the fact when it was very obvious there was going to be an issue that could be fixed during the build process.

If a subsequent owner ever wants the aeroplane to get re-engined to IO360 Angle Valve/horizontal induction and or Harzel metal CS, new cowl and engine mount will be required... But the entire FWF will need to be redone at that point anyway. Same as switching from O320 to O/IO360.

I have the 20 lb Saber plate and would do it again. Empty weight, without paint is just over 1100 lbs. If I ever change my engine from solid crank and go constant speed, it won't require a new engine mount.

And, I can drop 11-12 lbs from the firewall by replacing the PC680 with an EarthX.
