Notes

The Aichi E11A Type 98 Reconnaissance Seaplane (九八夜偵, Kyū-hachi Yatei) was an Imperial Japanese Navy flying boat used during the first year of World War II for maritime patrol duties. The Allied reporting name for this type was “Laura”.

The Type 98 was quite similar to the earlier E10A Type 96 (“Hank”). Type 98s were rare - only 17 were built. It was designed to be launched from cruisers or battleships in order to spot their shellfire at night, but the Type 98s were soon diverted to communications and transport duties. The Type 98s were displaced by newer craft such as the Aichi E13A “Jake” and Mitsubishi F1M “Pete”.

The Imperial Japanese Navy originally expected it might be important to use seaplanes for night shellfire spotting, but this soon faded for several intertwined reasons:

  • Inherent difficulty of night observation
  • Rapid improvement in shipborne fire-control systems
  • Operational vulnerability and complexity
  • Shift in naval doctrine from gun duels to torpedo attacks
  • Better uses for limited aircraft

The Kit

This is the 2020 release from a 1998 tooling of the Fujimi Type 98 Aichi E11A in 1:72.

I bought the kit on Plaza Japan for ¥1,890 in Jun-2025.

Build Log

It’s a very nice molding…

build01a

Installing a motor (works well with 3V PWM). Tested to make sure I get the rotation correct. I’ve added a 1N4001 flyback diode across the motor to shunt inductive voltage spikes.

build01b

build01c

I’ve added 1 figure (of the 3-man crew) as I don’t think others will be easily seen. This is a seated pilot from the IJN Pilots and Ground Crew WWII Red Box No. RB72053 1:72 set.

build01d

Fujimi included a neat alignment jig for the upper wing on the clear sprue.

build01e

build01f

Motor Control

I’m using a simple variable PWM motor controller based on a 555 timer. It works fine with a 3V coin cell to drive the particular motor I am using.

PWM gives a much more realistic, slower speed drive than just direct drive from a coin cell.

Circuit designed with Fritzing, see E11A.fzz.

Painting and Finishing

I had to pull out all the big guns to try and get these decals to settle before I can work on the finish!

Frame and Mounting

A quick watercolor of a dramatic sea and sky in a frame from Daiso…

build04a

Motor Control Board

I transferred the electronics to a small SO-16 DIP adapter with mainly surface-mount components

Rigging and Final Finishing

I decided to do the full rigging, and I think I’ve finally got a process that works well for me. CA is really variable in my climate without accelerator, but this made my process so much more reliable.

I have some Green Stuff World CA activator in a spray bottle, but I also read the warning on the bottle that basically said “don’t do that if you want to live”!

I tried using a brush to apply the accelerator instead .. so much better! Controlled application, no waste, and hope I won’t die so soon. Works with pre-application - dab to model, rigging dip in CA, then touch to model. Or reverse - CA to model, insert rigging, then touch with the brush.

build05c

I used some oils and AK weathering pencils to bring a bit more visual interest to the finish.
