The MVVS weight breakdown is like this: 33 oz motor only; 44.8 oz w/ muffler (bisson inverted),and ignition. Not much more than a 1.5 saito.
Actually comparing it to Sait you need to include fuel, mount, and ignition battery. So the total is:
MVVS 1.6
Engine: 33oz
Muffler 5 oz
Ignition 5 oz
Ignition battery: 3 oz
Radial mount: 2 oz
Fuel + tank : 13 oz (for 15 minutes)
--------
Total: 61 oz
Saito 150
Engine: 30oz
Muffler 3 oz
Ignition - none
Ignition battery: - none
Mount: 8 oz
Fuel + tank : 22 oz (for 15 minutes)
--------
Total: 63 oz
I have MVVS 1.6 (new not broken yet) on 11.5 lb plane plus 11 oz fuel (Powerline Hobby Edge 540 23%) and APC 18x6W turns 8300 rpm - unlimited vertical with enough thrust to climf out of hoover.
