RE: Building a Dynaflite Super Decathlon
Hi Bill
Finally I checked weight of mine (without fuel). It's exactly 7.4kg (16.3 lbs).
Regarding engine.
Even ZDZ-40 sticks a little over engine cowl.
It's installed up side-down.
Therer is spark plug cap sticking outside.
Someone here has a Decathlon with US, Fuji or ZG engine. If I remember, there was not too much out of engine cowl.
