Herewith for your interest a pic of the 36in. Zaic Trooper, completed this afternoon. It weighs 2.25oz, ballasted at 40 per cent, which I'm quite pleased with since I paid no attention to weight-saving. For instance, the plan stipulated 1/16in.-sq. longerons and I used 1/8in.
I think this could be a little goer off the 30m bungee so I've used a tip-up wing DT with button timer.
The Trooper should have the cabin roof glazed, too. But enough is enough....
The Trooper went up on the line for the first time this afternoon. No change to bench trim needed. It just floated to the top and would have been lost in third flight in a riser had it not been for the DT.
In my opinion 1/8in. rubber is OK but possibly a tad too strong 3/32in. would be ideal, but I dont have any. With the 1/8th, just a step of line tension was all that was needed in this afternoons gentle breeze. I thought it would need an auto-rudder, but the Trooper meandered into its own wide-ish circle with no trouble at all.
