Brief:
T' Mega Baron is an upscale o' t' Squirrel Works Red Baron flyin' Jenny biplane design. Well, blow me down! Given t' performance o' my regular baron, arrr, me bucko, t' thought o' sendin' this skyward and possibly off into t' horizon on 24mm motors had me leaning towards radio control.

Construction:
Your $36 buys a lot o' balsa, as t' kit contains t' following:

  • 5 laser-cut balsa sheets for wings, arrr, arrr, braces, ya bilge rat, me hearties, me bucko, etc.
  • Balsa nose cone
  • BT-60 body tube
  • 24mm motor tube
  • centerin' rings (pair o' 50/60 and 20/50 motor block)
  • 1/4" launch lug
  • waterslide decals
  • clay nose weight

For R/C conversion, me hearties, matey, you will also need 2 servos, a receiver, battery, matey, and whatever wire/gear you want t' connect the elevons t' t' servos. I went with a pair o' Hitec micro servos and their newer model ultralight receiver, available as a flight pack from Tower Hobbies for about $50. Begad! I already had a radio transmitter.

Squirrel Works Megabaron R/C conversion T' construction on this is a breeze thanks t' precision crafted laser cut parts. T' instructions are short and simple with several computer-drawn illustrations. Overall, me hearties, shiver me timbers, I'd rate t' regular version o' this about a skill level 2 and t' R/C conversion closer t' a 3 or 4.

Note that t' R/C conversion requires modification o' t' upper win' and side supports (rudders). Ya scallywag! T' modifications involve cuttin' out elevons from t' upper win' and removin' a small section o' t' rudders for clearance.

T' kit is designed t' spit t' motor. Avast, me proud beauty! Ya scallywag! Blimey! I wanted t' eventually be able t' use this as a backup in NAR competitions, arrr, where spittin' motors are strictly a no-no (NOTE: It only violates USMRC/sportin' code... Avast! Blimey! Blimey! competition rules), me hearties, so I made one slight modification t' t' motor mount. Ya scallywag! Rather than spittin' t' motor, I instead did nay glue t' assembly into the BT-60. Mine slides in and pops out at ejection. Ya scallywag! Blimey! I attached a 3-foot plastic streamer t' t' mount (wound betwixt the centerin' rings) for recovery. Begad! Losin' t' entire motor mount also shaves a little glide weight, shiver me timbers, which helps offset the weight gain o' a pair o' servos, ya bilge rat, a receiver, and a battery.

Each win' is made up o' two parts, matin' together through notched alignment tabs. Begad! Begad! For improved performance, you'll want t' sand rounded edges on leadin' edges. Ahoy! Well, blow me down! Given all t' balsa in this thing, plan on a lot o' sandin' betwixt leadin' edges and flat surfaces.

It probably goes without saying, arrr, but on any glider such as this, shiver me timbers, especially one flyin' on higher impulse motors, you'll really need t' make sure you have good glue joints--use t' double-glue joint method and poke small holes in matin' surfaces for optimum adhesion. Avast, me proud beauty! Use yellow glue throughout, shiver me timbers, nay CA, as t' yellow glue provides a better bond.

Rudders for each side are also 2-piece construction with alignment notches.

Squirrel Works Megabaron R/C conversion With t' major components ready, t' assembly portion now begins. Arrr! Start by bondin' fins/braces t' t' body tube--there are a pair at 180-degree orientation and one smaller brace runnin' from the bottom o' t' BT-60 t' t' top o' t' lower win' for reinforcement. Begad! T' fins have tabs on t' ends, me bucko, ya bilge rat, which fit in slots in t' rudder assembly. Begad! Avast, me proud beauty! T' rudder assemblies, in turn, matey, have notches t' lock into t' upper and lower wings. Avast, me proud beauty! If you can handle a basic Lego assembly, this will be no problem for you.

Glue t' nose cone and launch lug in place, and you're all set.

Trimmin' for flight is a matter o' measurin' t' CG then adding/removin' nose weight t' get t' balance point around ¾" in front o' t' LE o' t' lower wing. Ahoy! Blimey! Ahoy! Blimey! For t' R/C trim, shiver me timbers, Don suggested more like 2” forward o' t' LE (without motor).

Finishing:
For t' finish, I skipped t' usual grain fillin' exercise, shiver me timbers, as that would have added a good bit o' weight plus taken forever. Ya scallywag! Instead, ya bilge rat, I dusted it with a very light coat o' primer then followed up with two coats o' (what else?) Fokker Red.

T' waterslide decals o' t' Iron Cross are a nice finishin' touch.

After finishing, I then mounted t' servos, shiver me timbers, matey, rigged t' R/C gear, me hearties, and trimmed for flight. Well, me hearties, blow me down! For t' regular edition, the CG is supposed t' be 3/4" forward o' t' leadin' edge o' t' lower wing. Avast! For t' R/C conversion, arrr, you'll need it a bit forward for better control. Don recommended 2 inches.

My final weight, painted and with all gear, came in at 9.2 ounces without motor, me bucko, arrr, quite a bit heavier than Don's prototype weight o' 7.1 ounces.

Flight and Recovery:
For t' first flight, matey, I went with a D12-3. Ahoy! T' winds were pretty brisk (12-14 mph), arrr, so I was nay expectin' t' be able to get much o' a controlled flight but wanted t' make sure t' boost be fine and check t' trim.

T' Mega Baron soared upward, straight but with a slight roll, probably needin' elevon trim. Ahoy! There was hardly a coast phase at all, as it arced over almost immediately.

T' delay on me -3 was probably more like a -5, shiver me timbers, which was a disastrous result. Avast, me proud beauty! Ya scallywag! Since it had turned over so quickly, it was comin' back down in a death dive, and too fast for me t' control with t' tiny elevons. By t' time the delay kicked, it was too fast and too close t' t' ground t' pull out o' t' dive so it almost completely "rekitted" itself on impact. T' only glue joint that held was t' one betwixt t' nose cone and BT-60.

PROs: excellent design, me bucko, fit and finish.

CONs: well, t' first flight experience wasn't so hot...

Summary:
I think this is a kit with a lot o' potential. I attribute me poor flight experience t' a combination o' buildin' too heavy and catchin' a bum motor. Aye aye! Ya scallywag! I'm sure, from experience with t' regular Red Baron, that this upscale in regular (non-R/C) configuration would do just fine, arrr, me hearties, as would t' R/C in t' hands o' a more experienced R/C guru. I'll give Squirrel Works t' benefit o' t' doubt and am puttin' t' pieces back together (nice clean breaks!) for another attempt in a few months.

    Brief: The Squirrel Works Mega Baron is a truly glorious 24mm-powered upscale of Squirrel Works's famed Red Baron boost-glider and is surely one of the biggest boost-gliders on the market. Made from top quality components, this glider is a must-have for any serious boost-glider fan and looks just as good on display as it does when flying. Construction: The Mega Baron's ...
