As the modeling trend has moved from Free Flight toward R/C assisted flight due to smaller fields, and as the popularity of electric power increases, BMJR wanted to explore this new class of models known as Park Flyers. These small Speed 280 class electric powered models are intended to be flown in small fields like school yards or parks, and for indoor RC with Micro RC gear. The quiet electric power allows them to be flown almost anytime, even 6:30 Sunday morning.
| Ugly-30-RC |
B-301 |
 |
| The BMJR Ugly-30 started several years ago as a rubber powered sport free flight for a group of 8 year old boys as a summer project. It was then modified for electric and R/C. Now for 2008 we have completely re-engineered the kit specifically for electric RC. The kit contains parts for 2 interchangeable wings. A flat bottom airfoil with dihedral providing a very stable model with rudder/elevator and throttle control. An excellent trainer with “hands off” free flight stability. The 2nd wing has a fully symmetrical Airfoil with ailerons. Wing can be changed with just a few rubber bands providing a model with full aerobatic capability. A very nice transition form trainer to high performance model. Model has a span of 30" with 180 sq. in. area and a flying weight with brushless and LiPo of 10 oz. |
| Ugly-Sport |
B-302 |
 |
| Designed to accommodate several Speed 280 motor configurations for easy motor change-out allowing the builder to experiment with different motor/battery combinations. With a 33 inch wingspan, it is capable of all rudder/elevator aerobatics, including inverted flight. |
| Ugly-Sport Bi-Plane |
B-303 |
 |
| The Ugly-Sport "Bi-Plane" is based on design effort by Paul Bradley and published in the March 2002 issue of Model Aviation. Kit includes the basic Ugly-Sport, B-302, and includes parts for a second wing and plywood top wing mount. Model may be built as a low wing sport, and quickly changed to a Bi-Plane or Parasol Wing with a couple of rubber bands. |
| Ugly-Sport Second Wing |
B-304 |
 |
| The Ugly Sport 2nd wing kit includes only parts to build a second wing and the plywood top wing mouunt. It is intended for modelers who have a flying Ugly-Sport and want to experiment with the Bi-Plane/Parasol configuration. |
| Mini-7 |
B-305 |
 |
| The Mini-7 was designed by Harry Stewart around the readily available micro motors and radio equipment like that used in the popular "LiteStik" ARF type models, and published in the November, 2001 issue of Flying Models. Using the smallest radio gear, i.e. six gram servos and receiver with a GWS motor and a six or seven cell 2/3 AAA NiMH battery and the lightest covering should yield a model of approximately six ounces total weight. At this weight the Mini-7 can be flown indoors but is also capable of handling a gentle breeze outdoors. Flight times should range between ten and twenty minutes. The Mini-7 has a 40 ½" wingspan with 300 sq. in. of area. The BMJR kit has laser cut parts, full size plans, and a complete hardware package including a pull-pull control system. |
| Miles Magister |
B-306 |
 |
| The BMJR Miles Magister, designed by Dave Platt, has been engineered for electric power and micro R/C equipment allowing it to be flown in a small area, with full 4-channel control. With a 33 1/2" wingspan it is a true 1" to 1' scale representation, and may be built for static display. It is a very stable flyer, yet capable of scale loops and rolls. This is a COMPLETE kit containing over 250 items including 126 laser cut parts, trainer yellow covering, authentic British RAF marking decals and DuBro hardware. |
| Sperry Monoplane |
B-307 |
 |
| In 1921 the Sperry Aircraft Company produced a thick cantilever monoplane wing which was specifically designed to be interchangeable between the U.S. Curtiss Jenny, and Canadian Curtiss Canuck, advancing these bi-planes to state-of-the-art monoplanes. The wing was internally braced, in one piece and completely free of external bracing wires. Construction used stout “I” section spars giving the wing a safety factor of 15 before failure. The high efficiency of the wing and reduced drag over the wire braced biplane configuration, provided significantly improved performance.
The BMJR kit was inspired by an FAC Peanut by Doc Martin flown at Palm Bay and a construction article by Dave Lindstrum published in the Sept. 1995 issue of Model builder Magazine. Model has a 30” wingspan and 187 sq. in area, is intended for electric power, with full 4 channel control. With a wing loading of about 7 oz / sq ft we have flown this model with both brushed and brushless motors. |
| Electric-Flash |
B-308 |
 |
| The old Comet Phantom Flash rubber model inspired the Flash-E designed by Harry Stewart. It incorporates classic plan form features such as the tapered wing and semi-elliptical tail surfaces. As designed it was intended to be a small motor park flyer but it has proven to be a pretty good soarer and an excellent float plane as well. The Electric Flash has been flight tested with a wide range of electric motor/battery combinations addressed in the building notes. Wingspan is 44" and a the flying weight is in the 5 ½ oz. per square foot range allowing some slow relaxed flying. The BMJR kit has laser cut parts, full size plans, a complete hardware package including a pull-pull control system, and detailed building notes by the designer. |
| Baby Phoenix - PF |
B-310 |
 |
| The Baby Phoenix-PF (PF for Park Flyer) is based on the 1949 free flight design by Frank Ehling. The BMJR kit is true to the original design except for the fuselage being 1/4" wider to accomodate electric power and micro R/C gear. Model may be flown in lazy circles as a Park Flyer or climb an do some thermal hunting. |
| Fast Freddie 3 |
B-311 |
 |
| The Fast Freddie has been described as, “the Perfect Aerobatic Little Electric Airplane”, and the BMJR kit represents the 3rd version of the Freddie series designed by Carl Martin. The Fast Freddie III is a highly aerobatic indoor/outdoor low wind flyer with a 23 3/4” wingspan and a wing loading in the 5-6 oz. Per sq. ft. range. Powered by a GWS motor it will perform almost any Gymnasium indoor aerobatics short of extended hovering. It will ROG in about 3 feet and has NO bad habits. It performs extremely tight inside/outside loops and turns, fly’s inverted as well as upright, will axial roll and do great rudder maneuvers. With the steerable tail wheel it will taxi out to the flight line and back to the hangar with pride. |
| Splash-E |
B-313 |
 |
| The Splash-E designed by Harry Stewart is a relatively small (44" span), light (13-15 oz), electric powered, "wire-braced" flying boat. It is designed specifically around the inexpensive MGK motor, but is adaptable to most speed 280 size power plants. The distinction between a float plane and a seaplane is; a float plane is just a conventional land plane adapted to fly off water by the addition of floats; a seaplane is really a boat that has been adapted to fly. |
| Race-E |
B-314 |
 |
| Designed by Harry Stewart, the Race-E is and aerobatic Park flyer with a wing loading in the 6 oz. per sq. ft. range with a 40 1/2" wingspan and 242 sq.in. of area. The tapered wing and classic tail shape give the Race-E a great look in the air. The instruction address 3 power options including the inexpensive MGK for relaxed flying, geared speed 280 for aerobatic fun and brushless for pure vertical performance. The Race-E is not a 3D airplane, but is an excellent sport aerobatic design, and I have to say is the best flying, most fun model in our personal fleet. |
| Sniffer-PF |
B-315 |
 |
| The Sniffer-PF (for Park Flyer) is the same as the origianl free flight design with an instruction Addendum by Harry Stewart, and a complete hardware package for converting the model to electric RC. Model has a 30" wingspan and 139 sq. in. of area. The prototype weighed 5.3 oz. giving it a 5 1/2 oz per sq foot wingloading. The Sniffer-PF has proven to be a very stable flyer for a bit of relaxed nostalgia. Recommended power is the EPU-3 motor and 2 cell Lithium or 7 cell 280 mAh NiMh battery |
| Daddy-O |
B-316 |
 |
| The Daddy-O is a sport park flyer wit 32" wingspan and 194 sq.in. of area. Design by Thayer Syme based is on a 16” rubber powered free flight originally designed by Jason McGuire. On the ground the Golden Age Racer theme sets it apart at the field from the high tech electric aerobatic models, but once in the air she will hold her own, short of pure 3D maneuvers. With the “brushed” 280 motor and NiMh battery pack the performance is calm and predictable, providing some relaxed Park Flying. With a “brush less” and LiPo pack performance is excellent. She will jump off the ground in about 2 feet and if weight is kept to about 12oz. Vertical performance only adds to the fun. Construction is classic stick and tissue style enhanced with precisely fitting laser cut parts providing a lightweight yet very strong structure. |
| Simplex-30-RC |
B-317 |
 |
| The Simplex was designed by Paul Plecan and published in the February 1941 issue of Air Trails magazine. Paul reported that his original model was lost on the day it was test hopped. On its eleventh flight it flew Out-of-Sight in 33 minutes on a 15-sec. engine run. For those wishing to avoid the chase, a Park Flyer version of the Old Time Free Flight Clasic is available for electric RC with rudder, elevator and speed control. Flying weight with an MGK Motor and 2/830 LiPo is 7 1/2 oz. |
| Park Panther |
B-318 |
 |
| The original Panther was designed in 1938 by Walter Schutz as a free flight with a 46" wingspan and an ignition engine. The Panther was unique for it's time with a low wing rather than the more traditional high wing cabin type model. In 1939 it was kitted by the Peerless Model Airplane Company and became known as the Peerless Panther. The BMJR Park Panther was scaled down by Harry Stewart to a wingspan of 40” with an area of 227 sq. in. Only significant difference from the original design was to replace the under cambered airfoil with a flat bottom wing. For RC this change has produced stalls that are far more gentle with a wider speed range for more blustery conditions. It’s Free Flight roots are apparent as the Park Panther has demonstrated "hands off" stability, and produces very graceful loops and rolls, but does not like to be inverted. With a flying weight around 11 oz, depending on covering material and brushed vs. brushless power options, model has a wing loading of about 7 oz. per sq. foot for relaxed flying |
| Orion 1/2 |
B-319 |
 |
| In April 1960 Model Airplane News reported that the Orion by Ed Kazmirski achieves a new standard of high performance. In the MAN article Ed comments, " The Orion, like any airplane design, is one answer to a problem. The problem, in this case, was the need for a ship capable of more nearly perfect maneuvers." The Orion 1/2 by Paul Bradley is a 1/2 scale model of this classic design, and with brushless electric motor is capable of all the same maneuvers performed by the original. BMJR Model has a 36" wing span and area of 194 sq. in.
|
| Taurus 1/2 |
B-320 |
 |
| In January 1963, MAN reported, “…...in 1960 Ed Kazmirski’s Orion was the best multi offered to date – now the Taurus is the best”. The Taurus was designed to be a plane that would perform the maneuvers more nearly perfect, but more important, would be easy to fly. The big difference in the Taurus over the Orion is the wing section with a 19% thick airfoil, which helps eliminate tip stall, is not sensitive to slight elevator beeps, is stronger, and as speed increases the increased drag slows the model for a more consistent airspeed during maneuvers. Another big change was the use of “strip ailerons”, coupled with a short nose and long tail moment. The Taurus ½ by Paul Bradley is a scaled version of the original, is designed for brushless electric power, includes a steerable nose gear for ground handling, and fly’s like a larger ship. The Taurus completes the linage of multi channel pattern RC design staring with the Astro Hog in the 1950’s, to the Orion and Taurus. Model has a wing span of 36”with and area of 194” sq. Flying weight is around 15 oz. BMJR kit has 20 laser cut sheets of parts and a complete hardware pack. All you need to add is covering, motor and RC gear. $91.50 + $6.50 postage. |
| Astro-Hog |
B-321 |
 |
| Prior to the Astro-Hog, by Fred Dunn and published in the April 1958 issue of MAN, radio controlled models were all high wing designs. Consensus of the R/C flyers at the time was that low wingers were doomed and would never be suitable for R/C use. But with the introduction of multi-channel radio equipment featuring simultaneous control, ailerons were the answer. The Astro-Hog opened the door for performing complex maneuvers like slow rolls, four point rolls, and inverted flight. The design was reported to be aerodynamically sound and structurally capable of withstanding any normal abuse. It was also reported that the number of flights per crackup was increasing with the Astro-Hog which led many builders to add extra finishing details to their models. At 36” span the BMJR Astro-Hog is half size of the original 72”, and is truly a model of a model. With brushless electric power, and wing area 194 sq. in. and a flying weight in the 17oz range, its flight characteristic has proven to be excellent, and following the original structural design has produced a substantial airframe.

| Super Sniffer |
B-602 |
 |
| The Sniffer was an early Post War free flight model designed by R.G Schmith for the new OK Cubs and Anderson Spitfire glow engines of the day, and was produced a kit by Midwest Models in the early 1950’s. It is reported that the name came from it’s Thermal Sniffing ability but a complete history of the design appears nonexistent. The Super Sniffer is 150% enlargement of the BMJR Sniffer free flight model with only minor changes to the structure for RC and retaining the original outline. The 44” BMJR Super Sniffer may be built for either electric or glow, and flown for FUN. |
