I think your numbers are a little low on all the accessories for the BME weight you posted. Here's what I'd change:
3 oz ignition to 4 oz.
4 oz pitts to 6 oz.
3 oz battery to 4 oz.
0 oz switch to .6 oz.
3 oz mount to 6 oz.
---------------------------------------------------------------
Almost 8 oz difference. So it's more like 3.5 pounds.
Edit: but it's still at least a pound less than most of the other light weight 50cc gassers.

Let me get this straight. This engine is only ONE ounce heavier then OS 1.60 FX? Is that possible?
The 1.6FX is
2.7 pounds with light pitts muffler and motor mount RTF
The BME is 2.1 + 3oz ignition + 4oz pitts muffler + 3oz ignition battery + 3oz mount =
3 pounds RTF
I think you would run a 16oz fuel/gas tank with both motors.
You may be tempted to run a heavier prop on the BME and a larger spinner, but this is not necessarily so. If you compared the 1.6FX with 18x6w(4.75oz) & 3oz spinner against a BME with 22x10 or similar wood prop and no spinner BME would have the advantage.[8D]
Someone correct me here if I missed on my numbers.
The only weight I can argue with you on is the ignition battery. There I was figuring in a 2/3AA 1200mah 4 cell pack. Is the mount really 6oz?
Thanks for the info.
