Yes, it's the F3A version. It weighs 2 lbs 11 oz (1220 grams) with the ignition, exactly the same as 3W are quoting for the 28.
(Although ZDZ "forgot" to include the weight of certain bits and pieces, such as the removable prop shaft, prop washer etc.)

The model is my own design, with a molded fuselage. This was originally made solely for electrics, but I think a ZDZ will also fit. Access to the engine will be a little unusual, as the canopy extends right forward to the spinner. (This, in my opinion, is ideal for electrics, where you have full access to "everything" from the top.
Pictures taken last winter of electric prototype No. 1. Yippeee, that white stuff is coming soon....[&o]
