Been searching a bit, found some attempts to document the "real world" weights, decided to try my own thread to gather results. It could prove to be a VERY good resource thread, if folks will post their information. Here's mine:

BME 50cc - motor only - 48.5 oz
Plug/clamp for gnd - 1.1
Ignition - NO batt/sw - 3.7
Prop washer/nuts - 1.2
J&A Pitts Muffler/strap - 7.7

TOTAL - Actual MOTOR only - 62.2

Hangar 9 alum mount - 6.2

1650mah Nimh - 4.2
MPI H.D. Switch - .5

TOTAL INSTALLED AIRFRAME WEIGHT - 73.1 oz - NO PROPELLER, NO SPINNER

Please post your results in identical format, please, and use electronic scales, calibrated, if you have them. These weights were recorded on two different brands of electronic balances.

Thanks for helping spread information that lots of folks want to get, but never seem to!!!!
