it, so it can be left in the circuit if desirable for future use. Just leave the switch in the ppm mode until further programming is needed if you intend to do it this way.
Flying the Bogie 72 Before heading to the flying field I checked out my batteries with my Futaba
www.futaba-rc.com BR-3000 Battery Checker. It is a really great tool to keep you on top of your batteries. In the display screen it shows maximum voltage in nu- merical values and remaining capacity in graph percentage. Other screens give you cell voltage difference (minimum and maxi- mum), plus you are able to balance your pack cells with it. What a great tool. I picked a day with little wind to fly the Bo-

to last; however, if you take it a step at a time you will get there and be amazed at how well things go together and how great it looks completed. Having built another Mountain Models kit I knew what to expect when it came to good parts fit and thought- ful engineering. I wasn’t disappointed. The manual starts you out with building
the center panels. The shear web is glued to- gether first forming the correct amount of dihedral for the center section. One center section is built at a time so that it can be laid flat and held straight during the gluing process. I weighted each down, when ready to apply the glue, to make sure they were straight. Be careful: if a part doesn’t fit, check and be sure it is the right one in the right place. In some cases where there were tight fits
in a joint I used a fingernail emery board to open up the slot for a better fit instead of having to struggle with it. There are no mis- takes in this kit—only by you, the builder, not reading the manual. After building the wing tips I set about in- stalling the anti-rotation dowel pins, the magnets and the dihedral brace that retain the tips to the center section making them removable! A great idea by Mountain Mod- els, making transporting easier than haul- ing a 6-foot wing around. I gave each tip a slight tug; they seemed very solid. I’ll bet some will not use this feature and just glue the tips in place. The built-up motor box with the motor is removable, with the correct amount of down and right thrust built in, and held in place with three screws. The landing gear is also removable and held in place with one bolt, with careful thought given the need to straighten in case you bend it. With all the building completed I proceeded to sand the parts with 150-grit and 220-grit paper preparing them for the covering. I covered the Bogie 72 with Solarfilm, the recommended covering. If you have never used this covering material you will find it very friendly. It is applied at a lower tem- perature and has good shrinking qualities, so it tightens easily and stretches around compound curves. I purchased mine from
FLYING MODELS
www.mountainmodels.com. It is available in a wide variety of colors; in both opaque and transparent colors. Just read and follow the instructions on the roll and you will get along fine with it. I like to set up my power system before
hand to know the motor rotation direction. In fact you must set up the throttle range be- fore the first use of the ESC. You don’t need the IR receiver hookup for this. Turn on your transmitter, move the throttle to max posi- tion, connect the battery to the ESC. When you hear two beeps move the throttle to the minimum position. The only other necessary thing I did was program the ESC low voltage cutoff (LVC) to 9.6V using the IR receiver and programmer card. The IR receiver can be switched out or in (ppm/IR) with a slide switch mounted on
gie. Because it is very light I didn’t want to fight the wind and wanted to see its true flight behavior. I advanced the throttle for a long takeoff roll and slowly it rose into the air like it had been doing it all its life. As I gained altitude I thought, my what a gentle, easy airplane to fly. Honestly, when at altitude you could trim the rudder for a slight turn and set the transmitter on the ground and watch it fly. Of course not much for aerobat- ics… just a loop and a big barrel roll to help out the boredom after a while. What a great way to relax and fly as a change of pace.
The bottom line The Bogie 72 is not for everyone; however,
if you enjoy building or have a hankering to jump in and build one, this is a great kit. The laser-cut parts are superb and fit like a glove. Following along in the manual you can’t go wrong. It is absolutely the best way to build an airplane. Covering may be a problem for some but there is plenty of help online. Having built my own airplanes for many years, it was a real thrill to put this dude together. You will be amazed how well it will turn out.
With its graceful, classic lines and pylon mounted wing, the Bogie72 has all the grace and charm of a model from the Golden Age but builds and flies nicely with modern assembly and electronics.
