Jerry Smith built the Bogie 72(above left) from the Mountain Models kit. The 3-channel R/C model builds light and flies very well. The Bogie 72 outlines (above right) are similar to the original Cleveland Playboy, but to better
to get a little over a half inch of motion at each tip, which actually looked about right. So did all the effort pay off? You bet it did, and far better than I would have ever ex- pected. I had the privilege of doing the maid- en flight, and because of the many flights on the original p-type, pretty well knew what to expect as a 3-channel system. So if the warp- ing didn’t go well, or proved ineffective, we could always revert back to the rudder for the turns.
As it turns out, the warping was quite ef- fective, more so then I had expected, and aside from a fair amount of adverse yaw— which is exactly what I expected, the model turned well. Control was a little sluggish on input, and the roll rate won’t set any records, but after a couple of turns and re- coveries it proved itself to be very consistent and predictable, and was really a fun little airplane to fly.
In the end, the 43.5-inch span model tipped the scales at 13.5 ounces, powered by a Suppo 2208 outrunner on an 800 mAh 2S Li-Po battery. Three sub-micro servos han- dle the controls nicely. Originally the model was powered by a Mini-Olympus 2.33:1 gear drive with a Speed 400 motor, 10A ESC, 7-cell 600AE Ni-Cd battery and two Cirrus S-90 servos. Flying weight then was around 19.5 ounces. Well done Mike, and I am really happy to see the level of curiosity that is still there where these less than com- mon ideas come to the surface from time to time.
accommodate the c.g. the pylon was moved aft, and the fuselage shape was altered slightly to access the R/C equipment more efficiently. It is powered by a Scorpion 2215-18 outrunner motor with a 3-cell Li-Po and uses 3-channel R/C.
The readers are still at it too This time we’ll begin with a very familiar name, Jerry Smith. Jerry has been busy building the Bogie 72 from Mountain Mod- els. The Bogie is reminiscent of the old Cleveland Playboy, and according to Jer, flies much like the Playboy too—slow and gentle, and does great in lift also, which is no real surprise either. There were a couple of deviations from the Playboy in the design though: the pylon was moved aft to better accommodate c.g., and the fuselage was re- shaped a little to make room for the R/C components. It is powered by a Scorpion 2215-18 outrunner motor with a 3-cell Li-Po and uses 3-channel R/C. The 29-ounce model has a wing area of 655 square inches, and with a wing loading in the 6.4 ounces/square foot range, you know it’s going to require some close attention in good air to insure it comes back at the end of the day. The Bogie is a terrific looking model, and between Mountain Models ability to produce a great kit, and Jer’s propensity for building a beautiful model, this one will no doubt be a winner.
Then swinging back toward freeflight, Dave Wagner is back with another Dime Scale racer from Skylake Models. This one is the Keith Rider Bumblebee, which is an off- shoot of the Rider Jackrabbit. The model is finished in tissue and dope, printed from files provided by Skylake. The very colorful model finished out at 18.5 grams, and once the field is back open for flying, the trim
flights will get underway. No doubt the mod- el will be a superb flyer.
Meanwhile, another false start has been resurrected and finished and is proving it- self to be a worthy flyer as well. John Pakiz started the Chuck Hollinger Cruiser a cou- ple of years ago but never quite got as far along as flying the 30-inch span model. Originally John had built the prop but dis- covered early on that it wasn’t going to work well, so he went with a 9-inch Peck Polymer’s plastic prop that is working out great.
Trim flights are showing great potential right off the board, requiring only a bit of right rudder and a dab of nose weight. The Cruiser is a bit reminiscent of the old Pacific Ace 30, which was also a very capable flyer, so there’s no doubt she’ll be a steady and consistent flyer.
Well guys, thanks again for another month of terrific input. Do keep those pho- tos coming so we can share the fruits of your labors with other like minded modelers out here. In the meantime, don’t be afraid to try something that others might raise an eye- brow over. You’d be surprised at what will actually work. Funny thing, for years one of my main criteria in any new design was to first find three people that would claim the idea would never work. They weren’t hard to find, and from it came some great stuff. So reach for the unusual and see where it takes you. One thing’s for sure, it won’t be boring.
