Cessna 337 modifications

[kenneth]

i have come across this photo (the lower one in the attachment) showing an unknown modification to a Cessna 337 Super Skymaster. the only hint is its South African registration zu-ago (or agu). the top photo shows a Lynx, an armed version used in Rhodesia, however the other aircraft with the glass nose is mysterious; a google search on the web with subject zu-ago and zu-agu yielded nothing; can any reader shed light on this aircraft?

I searched on "ZU-AGU cessna" and found this discussion thread:

Seems this was a Cessna modified by a local owner/operator in South Africa.

Contour also flew a single-turboprop 337. The Honeywell (?) engine replaced the front engine while the aft fuselage was extended to hold cargo. Removing the aft fuselage fairing would also allow it to drop cargo like a C-119 Flying Boxcar.

A couple of other Americans modified 337s - similar to that one-off South African prototype - by fairing over the nose, but installing turbo-props in the aft engine nacelle.

Robertson offered a STOL kit. The most obvious external difference was extended dorsal fins along the tail booms.

Minor modifications included an air-conditioning system that added a belly-scoop
Vaguely resembling the belly radiator on a P-51 Mustang fighter.

Less obvious was the turbo-charged, TIO-550 powered Riley Rocket offered by a San Diego conversion shop.

thank to you all for your kind replies


another Cessna 337 modification from Turbo Wing: flaps removed, and fans put in place - see their website

That Sout African civilian pusher conversion looks an awful lot like a cross between a Cessna 337 and a Patchen Explorer. Coincidence that the one and only Patchen Explorer was sold to and still lives in...South Africa? See http://www.secretprojects.co.uk/forum/index.php/topic,20122.msg231366.html#msg231366

Hi All -

The U.S. Navy also flies a modified 337 called the Pelican - photo at:

i nearly thought that nose came from a Partenavia P68

riggerrob

have you got more information/pictures about the Contour Cessna 337 and the Robertson STOL conversion?

 

[riggerrob]

Sorry, I miss-spelled "Conroy." The same factory that converted all those Super Guppies also converted a sole Cessna 337 with a single Garrett (?) turboprop in the nose. The aft fuselage was extended. The sole Conroy 337 was converted during the 1970s. A few photos were published in Air Progress magazine.

 

[Stargazer]

The 1968 Conroy STOLifter was a single-engine conversion of the Cessna 337 with a single 575hp Garrett AiResearch TPE331-25A turboprop engine (tractor only), an upward opening aft fuselage and the fixed undercarriage of the Cessna 336.

Here is a series of photos:

 

[elmayerle]

The Conroy STOLifter pretty much had to use the 336's fixed landing gear because the 337's main gear folds up under the rear engine and that revised rear end doesn't have provisions for that.

 

[riggerrob]

Good point about the fixed gear on Cessna 336 Skymaster.

If you compare Cessna's single-engined 205, 206 and 210, you will notice that the fixed gear 205 and 206 have plenty of room in the aft cabin, making them popular with skydivers and bush pilots. 205 and 206 jump-planes routinely carry 6 jumpers. Most jump-planes only carry an hour or so of fuel to keep within certified gross weight.
OTOH in the 210, the gear wells raise the rear floor so much that it becomes little more than a 4-seater with a shallow baggage compartment.
I have only jumped from a single 210 and we struggled to cram 4 jumpers inside, considering that the third seat row is barely tall enough for children.

Hi,

here is a Basler Turbo 33/Spectrum SA-550 picture,a development of Cessna 337.

Here is a modification to Cessna-337 into Gyroplane;

Hi Hesham
The gyroplane 337 was actually built and flown. Here is a picture of N9112A
Originally known as Hawk 6G is was later better known as the RevCon 6G (for Revolutionary Concept 6G). First flight was 22 September 2001

Re: Conroy Stolifter drawing

Great find, RAP.

I'd like to correct the mistake on the image file's title, though.

This was the Stolifter, NOT the Stratolifter!

Re: Conroy Stolifter drawing

Nice find RAP - I've put it on my sniper so fingers crossed....

Enjoy the Day! Mark

Hi, I search for a picture of the Cessna 348/O.2T (1 Prototyp built) and of the Cessna 351/O.2TT (mock up was built).

I found this when I looked online. Is this the machine that we’re looking for?

Cessna’s O-2TT Was Designed for Forward Air Control Missions

The Cessna O-2TT concept was proposed as an intriguing blend of design elements that never reached the production stage.
