I have been wrestling with the choice of engines and was considering a DA 120 or a DLE 120 but your analysis has redirected me to consider my old basic DA 100 I have sitting in a box.Īs you mentioned, the Bidule is smaller and lighter -and a little cleaner- than the Porter so parasitic drag may be less which also favors the 100 size engine choice. Wheels: DuBro 5" Treaded Lightweight Wheel for nose gear and a pair of DuBro 6" Treaded Lightweight Wheels for the main gear. Hitec HS-7954SH for nose wheel sterring (one total).īatteries: NoBS Batteries 2-cell 6.6v A123 LiFe 2,500ma packs, 2 for radio gear and 1 for ignition ( three total)
Servos: Hitec HS-5645MG for Ailerons, Elevators, Flaps, Tow Release, Choke, and Throttle. Spinner: 4" Dave Brown Vortech Aluminum Spinner So, cost is a factor, and therefore here are our choices: Do we use stock mufflers and save the cost and weight of canisters or tuned pipes? Our reason for this plane is to have a backup tow plane that is less costly than either the Porter or Decathlon, and one that we would not be as reluctant to fly on less than ideal days. So, the Bidule 111 is smaller and lighter weight than the ems like the DA-100 should be plenty of power for the size and weight of the plane.
Also, the included 1500cc (50 oz) fuel tank is a tight fit, so there will not be a 100 oz tank option here.that means the Bidule will be carrying 50 oz. Our Porter is the 3.37M span version so the 3.0M Bidule 111 has about 14-1/2" less span. Consequently, its AUW will be about 8-10 lbs. Our dilemma.we have both a DA-100 and a DA-120 looking for a home.which engine should we chose?Ĭompared to the Porter, the Bidule 111 (being a non-scale airplane) has a smaller fuselage and less overall mass. The DA-100 and DA-120 engines share the exact same size mounting bolt pattern and similar size and weight to the DLE 111. The Bidule 111 is designed around the DLE 111 twin cylinder gas engine. TopModel (France), under the banner of their ECOTOP brand, now offers the 3.0M Bidule 111 which is about the same size plane as the much beloved 3.2M Pilatus Porter.
