Yoshioka Bingo.F3A

JGW_1990

The Yoshioka Bingo.F3A is done, and it has been a journey. I bought the kit from Ishii Mokei several years ago and have built it in stages, enjoying it a lot. The Bingo.2M is originally a 3D plane for YS engines with oversized control surfaces. Mine is the first F3A-variant called Bingo.F3A with normal ailerons and elevators. I ended up buying a new wing for it, the “Pro” version which has is fully sheeted, features more taper and flaps. So mine has ended up a hybrid. The current version being sold by Yoshioka has support for electric motors, angled stabilizers, smaller flaps and other minor modifications.

The finished weight is 3,85 kg without batteries. I’m using Hacker EcoX F3A 4600 batteries that weigh 900 grams, for a flying weight of just over 4,8 kg. That’s not bad considering it has a clear plastic cockpit and a pilot on board, and 7 full-sized servos! I could have made 4,5 kg if I had used a  smaller RX battery, eliminated the flaps and pilot, smaller servos, used a carbon prop etc. The kit is extremely lightweight.

Equipment used:

  • Plettenberg 30-9 motor
  • 19x15x5 Xoar Prop
  • F3A Lorenz carbon undercarriage, fibreglass wheelpants, MK wheels
  • Futaba R7008SB receiver
  • Futaba T16SZ transmitter
  • Futaba S3073 Servos (4) for elevator and flaps
  • Futaba BLS171SV Servo (1) Rudder
  • Futaba BLS174SV Servo (2) Aileron
  • Graupner 1200 mAh 2S LiPo RX battery
  • RCsense.com efuelgauge for S.Bus
  • Oracover

The tailwheel came with the kit and is a high quality item

I painted the carbon undercarriage white to match. (I know, I know…)

Of course I had to have matching wing bolts

The interior is spacious and fairly straightforward. It took a bit of work to convert it to electric, with a reinforced battery tray and modified nose.

I painted the rudder horns and linkages white (Never said I was sane…)

Flaps allow for some creative mixing. When the throttle is pulled back, the entire wing can be an airbrake if I want it too.

My Planes: Yoshioka Aladdin Hyper 45L

After a long wait I got an e-mail reply from a very friendly gentleman at Yoshioka model shop. He offered me an Aladdin kit, tailgear, trike or retract version of my choice at 30% discount plus shipping. Money changed hands and the plane was surprisingly quickly at my door. A very friendly company that handled my Norwegian mini-order professionally like it was a million-dollar contract. Excellent service!

The kit is extreme quality and value. The wood is so good it will match anything MK has to offer. The plans are detailed in the extreme, and all hardware is supplied, even a gigantic sheet of decals, not commonly seen in balsa kits.

The design of the nose features an offset engine, it’s positioned at 90 degrees and slightly offset from the centreline of the model to be able to hide the muffler nicely along the side/belly of the plane. An interesting design idea that give the plane a very distinctive look.
