That looks like a seaplane being cataputed off a battleship.

Is a battleship the same thing as an aircraft carrier? 

If so, we have a few more designs available.

this is a rubber powered model also on display at the Glenn L. Martin Museum.

This photo proves that a PBJ-1 (B-25) made a carrier landing. the pilot was Lt. Cdr. H.S. Bottomley on the USS Shangila on 15 November 1944.

Doc;
profile, class 1 or class 2? 

maybe i can find sonething for you.

Tom

Don't they give extra points for twin engines?

sent to my father with plans in '68 from Don Gerber.

Charlie Reeves is a well known stunt flier and designed and flew and published a Bell Airabonita Class 1 Carrier design in the mid sixties.

Why no hook?  Because the aircraft landed slowly enough the arresting gear as we think of it today wasn't needed.  At one time the cables ran the length of the landing area and hooks on the landing gear spreader bar were used to engage them.  They weren't to stop the aircraft but to keep them from going off the deck to the side of the ship.

The idea of using arresting cables across the landing to stop an aircraft on an operational carrier using a tailhook on the aircraft was a British development post WW1.

Cables and sandbags were used when Ely landed on the platform placed on the Pennsylvania.  But she was stationary when he landed and it was a very short landing area.  The pictures on the web page show the approach and landing.  That took guts to try.

As you look at the photo sequence you can see he approach very slowly in the last bit of the flight (nose high attitude).  I can't see any type of cable engagement mechanism on the airplane.  It might like some runway barrier designs where the cables went up over the wheel and caught on the landing gear strut.

There is a record of a Cessna O-1 Bird Dog landing on a US Carrier of the coast of Vietnam in 1975.  Obviously no arresting hook and not an "official" carrier trial, but accomplished.  but wouldn't that make a pretty carrier model?

  A few years ago I did some research on this subject. I went to the US naval aviation museum and inquired about the MO-1. They came up with some nice 8x10 photos and I bought 3 at about $15 each. Kind of spendy but I collect this kind of stuff . One photo shows an MO-1 naked with no skin, no hook visable. The other two I have are side views, no hook visible. These are 8x10 copies from original negatives and are very sharp and clear. I haven't seen a whole lot of MO-1 photos, maybe 12, but none had a hook. My conclusion is MO-1s didn't have a hook.
  I think the carrier rules were changed to accommodate this fact. The rules went from "made a carrier landing" to "made a carrier landing or designed to land on a carrier deck" soon after the MO-1 became popular.                 
  The hooks that were on some early aircraft axles were indeed to keep the aircraft from going over the side. They were called anthwurp (sp) hooks.
  The O-1 bird dog that landed aboard the USS Midway during the evacuation of Saigon was flown by Major Bung Ly with his family on board.

It doesn't exactly capture the imagination with the power and punch of an F4U or F8F, though.

WELL LIKE IT OR NOT THAT IS EXACTLY THE WAY IT WENT DOWN. IT ALSO DIDN'T TAKE LONG TO CHANGE THE ENGINE REQUIREMENT OF DEAD STOCK PLAIN BEARING ENGINE TO ANYTHING GOES. BUT ALL IN ALL IT'S STILL A BUNCH OF FUN NOW ISN'T IT?     MIKE 

Well here's the deal for me. I build a Guardian rendition with a hook and try to snag a line with it. Or a Mustang, Airbonita, Bearcat et al. Along comes the high wing MO-1 and suddenly a no hook airplane is OK. Kinda like having a engine shutoff on a stunter and everyone else fidling with trying not to over run. Something just ain't right. Might not bother some but it has always bothered me.
Thanks

Been going on for 30+ years and nobody filed a protest until the last year I ran carrier.  Then it was over the fuel tanks not being completely enclosed.  The MO-1's in question had been flown in  previous NATS with no problem.  Nobody has ever made a proposal to correct that.  They worry more about the clearance around the protruding parts than the fuel tank it seems.  I was not flying carrier when the slider made it thru and can't get no support to eliminate it.  But, then again I am learning to hang the plane in an unreal attitude.  DOC Holliday

Doc, you and I know why there has never been any protest!  There are some sacred cows,right?

Sliders aren't allowed in nostalgia! You can try to hang and some people can do it without a slider. If you look at the old rules the angle of low speed flight was not regulated. When sliders first came out a limit of 30 degrees was set . Then in a few years changed to 60 degrees. So get out the Bearcat and compete and don't worry about the hang thing.   Mike
                           

NOSTALGIA CL NAVY CARRIER                  ALL THE RULE WOULD NOT FIT CHECK OUT RULE 3.2   Mike
(1 January 1999)                                   
1.  Philosophy:  The Nostalgia Navy Carrier event offers Carrier flyers an opportunity for additional Navy Carrier competition in a relaxed and enjoyable atmosphere.  It recreates an earlier period of Navy Carrier flying which predated the prop-hanging slow flight which characterizes today's competition.  As the years separate us more and more from the models, engines, and flying styles that formed the beginnings of the modern event, Nostalgia Navy Carrier will help to keep alive the memory of those earlier years.  Because the models are simpler than those used in modern competition, Nostalgia Navy Carrier may introduce new flyers to Navy Carrier competition.

2.  Applicability:  The CL Navy Carrier rules as published in the 1974-1975 AMA Official Model Aircraft Regulations shall govern this event except as modified below.

3.  Model Requirements:  Model design is unrestricted except as specified below and in the AMA Official Model Aircraft Regulations.  To encourage models which accurately reproduce actual nostalgia era Navy Carrier models, bonus points are awarded.
 
  3.1.  Engine Specifications:  Engine and fuel system specifications shall be as listed in the current AMA regulations for each event.

  3.2.  Moveable Leadouts:  Vertical or horizontal position of the leadouts relative to the model may not change in flight.

  3.3.  Electronic Control Systems:  Electronic control systems are not permitted

4.  Builder of the Model:  The builder of the model rule does not apply to Nostalgia Navy Carrier.

5.  Historic Model Bonus:  A bonus of 20 points will be awarded for models which were published or manufactured prior to January 1, 1978.  The Contest Director may require proof of eligibility, which shall be the responsibility of the contestant.  Proof may consist of dated published plans, magazine construction articles, or advertisements.  To qualify for this bonus, models must comply with the following requirements:

  5.1.  Modifications:  No modifications to the original design are permitted, except as listed below.  Any modifications other than those listed in section 5.2 which, in the opinion of the event director, significantly change the appearance or performance of the model as it was originally designed, shall not be permitted.  This prohibition includes, but is not limited to, changes in airfoil, changes in dimensions, and use of moveable control surfaces not included on the original design.
 
  5.2.  Allowable Modifications:
    5.2.1.  Landing gear may be changed in length or material, but must exit the model at the original position.  A tail wheel may be substituted for a skid and vice versa.  Wheels may be of any diameter.
    5.2.2.  Leadout position may be changed from that shown on the plan.  Ground-adjustable leadouts are permitted.
    5.2.3.  Control travel, control mechanism location, and control mechanism may be changed.
    5.2.4.  Tip weight may be changed or may be adjustable.
 
NOSTALGIA CL NAVY CARRIER
(CONTINUED)
   
    5.2.5.  Tail hook and its location may be changed.
    5.2.6.  Structural changes to strengthen the aircraft are permitted.
    5.2.7.  Building and finishing material substitutions are permitted.
    5.2.8.  Location of access hatches may be changed.
    5.2.9.  Engine mountings may be changed, and engines of different displacement may be used.
   
6.  Non-schnuerle Engine Bonus:  Non-schnuerle engines will receive a bonus of 20 points.

7.  Carrier Deck:  A carrier deck corresponding to current AMA regulations will be used.

8.  Records:  Records will not be established for Nostalgia Navy Carrier.

9.  Combination of Classes:  Class I and Class II may be combined for Nostalgia Navy Carrier.  If classes are combined, Class I models will receive a five percent bonus on total score (multiply Class I total score by 1.05).  Profile Class will not be combined with Class I and Class II in Nostalgia Navy Carrier.

.....

It IS a competition, one enters to win, so one uses the best tool for that purpose, nothing bewildering there. What is bewildering to me is that those who object most to MO-1s don't even fly the Event.

One last, long overdue, thought. Bob Frogner has become one of Carrier's finest Torchbearers, and I really appreciate his comments on this Forum. Thanks BFrog!
