RE: 2 or 4 stroke engine in a trainer ?
All my weights include the muffler, muffler bolts, prop num, washer, whatever it came with and all on the same digital scale.
Saito .72 18.1
Magnum .52 17.7
OS .46AX 17.2
Evo .46 17.2
TT Pro .46 17.1
Tower .46 16.9
GMS .47 16.5
You may have some kind of fantastic Pro .46, but there ain't no way mine pulls a 13-6 prop like my Saito .72
