Peter Rake's Besson MB411


After much persuasion on my part I convinced Peter to do a float plane .

This is it , the Besson MB.411 built for the French Navy to be used as a spotter plane on their new submarine the Surcouf.

The first MB.411 served from September 1935, until the sinking of the Surcouf off the West Indies in February 1942 .

General characteristics

Crew: 2
Length: 8.25 m (27 ft in)
Wingspan: 12 m (39 ft 4 in)
Height: 2.85 m (9 ft 4 in)
Wing area: 22 m² (237 ft²)
Empty weight: 760 kg (1,676 lb)
Gross weight: 1,140 kg (2,513 lb)
Powerplant: 1 × Salmson 9Nd radial piston, 130 kW (175 hp)
Performance

Maximum speed: 190 km/h (118 mph)
Range: 400 km (249 miles)
Service ceiling: 5,000 m (16,405 ft)

The Marcel Besson MB-411 derived from the MB-410 ordered on 24 August
1932 and destroyed in 1933 whilst undergoing official acceptance trials.
A second prototype was ordered, but, due to the disbandment of the Marcel
Besson company, this reconnaissance aircraft was built by ANF-Les Mureaux
and designated MB-411.
It was, indeed, specifically designed for housing in a cylindrical hangar in
the back of Surcouf 's -- submersible gunship -- conning tower.

The aircraft could be disassembled rapidly for stowage and re-assembled
within 4 minutes of removal from its hangar. It could be lowered to the
water and retrieved by means of a crane.

The MB-411 No 1 was originally a single seater and underwent official
acceptance trials in August 1935; then was delivered to the Surcouf for
proving trials.
Several modifications were demanded, including conversion to two
seats configuration; so the aircraft was returned to ANF -L.M. early in 1936.
At the end of May 1936 it was returned to the Surcouf and in June a second
MB-411 was ordered...

This will be a 1/12 scale model so a WS of 39" and a length of 27"

Interesting. Typically French (Read, UGLY).
Looks in profile like a Hansa Brandenburg W29 after a couple of generations.

Cheers,

Great Choice!
I have a part built F/F one for a KP-01 from a Don Srull plan. Mike Midkiff also did one at a lrger size than Don's

Did some hunting and turned up a few photos of it (and a few questions!)
The story of the Surcouf makes for interesting reading.
I look forward to following this build, might get me back to my stalled project or, failing that, I might just bin it and do this version.

Peter Rake's Besson MB411

Dig it! This plane made it all the way to the last 2 planes on the narrowed down list that I had to chose between, a few builds ago. I even have a set of GWS floats stashed away, in plans of a future build, although you only need one float.


Here's a nice one from Jurgen Heileg's blog posts:


There's also the Mike Midkiff recent small rubber powered kit release.

I was also struck by the similarity to the Hansa Brandenburg W29

Quite right about the spelling of Besson , I was able to correct the text , but I can't correct the title .

How does one do that ?

Subscribing to this one!
I downloaded a 3-view last month and was considering CAD'ing up an own design. No need to now we have a Rakian version on the way

Lake: has Peter finished the design or have you just managed to convince him to start it?

Really looking forward to your progress
