[11], Prior to the United States entering World War II, J-3s were part of a fund-raising program to support the United Kingdom. Are there any opinions as to how it relates to performance? The L-4 was used extensively in World War II for reconnaissance, transporting supplies, artillery spotting duties and medical evacuation of wounded soldiers. :), Once, while having a discussion (friendly argument) with Atlee, he asked me "...don't you think Mr. Piper knew what he was doing...?...".
[15][self-published source? A place for friendly off topic postings and discussions. maybe a rudder mix could help too? On April 29, 1941, all 48 Flitfire aircraft, one for each of the 48 states that made up the country at that time, flew into La Guardia Field for a dedication and fundraising event which included Royal Navy officers from the battleship HMS Malaya, in New York for repairs, as honored guests. The completed wing assembly will be a single piece bolt-on type wing but you need to plan to store and transport that 81″ fragile wing somehow. I believe mine is a little over 5 inches. [3][4] When he saw the redesign, Taylor was so incensed that he fired Jamouneau. The main gear on the Cub Special Trainer consists of individually sprung wheels on which are mounted low-pressure tires. I have read that one of the differances between the cub and PA 14 is the angle. Whats the consensus? I know I could use some improvement myself. Piper only contiuned what Taylor started. For for the earlier Taylor design, see, Certified/factory-built aircraft manufactured in Canada, Piper J-3 Cub Film Series (TM Technologies, footage from 1937–1948 shows step-by-step construction.
There is a STC that should be out for the -18 within the next year that will probably not change your thinking, but the facts will be presented that (Piper was not always right). The classic yellow PIPER J-3 CUB is America's all-time favorite light plane!

Well, thanks for jogging my brain, the final neccessary synaptic connections were made, and I finally figured out what happened to my cub....the pitching moment of the airfoil dominates. Good Lord, a tail heavy Cub, can't think of much worse. endobj Many Cubs are still flying today. I can only assume the firewall repair was not straight since the rest of the plane had not been touched. After the war, thousands of Grasshoppers were civilian-registered under the designation J-3. Later in 1930, the company went bankrupt, with Piper buying the assets, but keeping founder C. Gilbert Taylor on as president. For these operations, the pilot generally carried both an observer/radio operator and a 25-pound communications radio, a load that often exceeded the plane's specified weight capacity. I wouldn't worry too much. This new Cub seems very tip stally and the tail doesnt pop up when you give it throttle like other Cubs I've had. Come on people lets pull out heads out of the sand. [19] Some 5,413 L-4s were produced for U.S. forces, including 250 built for the U.S. Navy under contract as the NE-1 and NE-2.[20][21]. 0000005973 00000 n endobj
It was a nightmare, no amount of trim could make it fly straight. [11] During the Allied invasion of France in June 1944, the L-4's slow cruising speed and low-level maneuverability made it an ideal observation platform for spotting hidden German armor waiting in ambush in the hedgerowed bocage country south of the invasion beaches. Billed as a Flitfire, a Piper Cub J3 bearing Royal Air Force insignia was donated by W. T. Piper and Franklin Motors to the RAF Benevolent Fund to be raffled off. 0000001268 00000 n 0000004557 00000 n In 1936, an earlier Cub was altered by employee Walter Jamouneau to become the J-2 while Taylor was on sick leave. You do this by moving the upper longerons where they are welded to the tail post. I think the problem is relative to this specific airframe, and not the design, itself. Questions and Answers - Modifying Stabilizer Incidence - I purchased a very well kit-built Great Planes Piper J3 Cub (40). [29], A curiosity of the J-3 is that when it is flown solo, the lone pilot normally occupies the rear seat for proper balance, to balance the fuel tank located at the firewall. After Piper moved his company from Bradford to Lock Haven, Pennsylvania, the J-3, which featured further changes by Jamouneau, replaced the J-2. The light wing loading, hands-off stability, and forgiving flight characteristics that made the Cub so popular with full-scale pilots are also ideal for model builders. Heard that once, thought it was good. From the PA-11 on through the present Super Cub models, the cowling surrounds the cylinder heads. Another quick measurement is to see if there is a 2.5 inch difference between wing attach points in relation to the HR. trailer <<92E6E88797DE424B8B8DF302BD25450C>]>> startxref 0 %%EOF 64 0 obj <>stream When you measure the incidence, is that at the top of the fuselage,where the wing sits ? 0000001695 00000 n The angle of incidence on the J-5 and the PA-12 are the same (Same Basic Fuselage) and is different from the J-3 and PA-18. 205 It had accommodations for a single passenger in addition to the pilot.
When I bought my cub, I discovered that it had been pranged several times without the benefit of a mention in the logs....but the first thing I noticed was that it was a dandy deathtrap. ��!�bi`Q��4{�r���_��$ˀ�Wfb�l�����A�A�Al� P���!�=���a�Vu�� ��}�RB.>jLa��`����������p�t ��N G1�Հ�ķ �CB� endstream endobj 38 0 obj <> endobj 39 0 obj <> endobj 40 0 obj <>/ColorSpace<>/Font<>/ProcSet[/PDF/Text/ImageC]/ExtGState<>>> endobj 41 0 obj <> endobj 42 0 obj <> endobj 43 0 obj <> endobj 44 0 obj <> endobj 45 0 obj [/Separation/Black 46 0 R 56 0 R] endobj 46 0 obj [/ICCBased 55 0 R] endobj 47 0 obj <> endobj 48 0 obj <>stream 0000002500 00000 n Statistics for the 1946 Piper J-3 Cub were as follows: If … I have a smart level, but I'm not sure what to referance off on the fuselage.

Everyone, myself included puts on long gear to achieve a higher angle of incidence so that we can get off shorter and have more prop clearance at three point.

I wonder how that changes things, if any? 0000000856 00000 n Built an Ikon West 1/4 scale Super Cub last winter. Newsreels and newspapers of the era often featured images of wartime leaders, such as Generals Dwight Eisenhower, George Patton and George Marshall, flying around European battlefields in Piper Cubs. I went with the jackscrew and yoke. I noticed during building that the incidence on the plans was 0 wing and 0 stab. Hundreds of Cubs were assembled from parts in Canada (by Cub Aircraft as the Cub Prospector)[26], Denmark[27] and Argentina and by a licensee in Oklahoma.[28]. Do you really believe that Piper built the cub perfectly? 3 Comments. 0000012481 00000 n They both fly fine for me. I have a smart level, but I'm not sure what to referance off on the fuselage. I noticed during building that the incidence on the plans was 0 wing and 0 stab. The J-3 Cub promotes the use of “Barn Door” style ailerons which means that they replicate the looks of the original and are not simply a strip of balsa that runs down the complete length of the wing. ... For the laminated parts, such as wing tips and tailplane edges, use only PVA after first soaking the balsa strips in water, do not remove excess water, the water is essential for thinning the PVA as well as making the wood more bendable. Statistics for the 1946 Piper J-3 Cub were as follows: :crazyeyes: I was blurry eyed when I posted that, I meant to say "horizonal stabilizer".

Triggs, Modern Aircraft Series (Sports Car Press) 1963. [25], An icon of the era and of American general aviation, the J-3 Cub has long been loved by pilots and nonpilots alike, with thousands still in use. 6 0 obj Sponsored by William T. Piper, a Bradford industrialist and investor, the affordable E-2 was meant to encourage greater interest in aviation. So watch out. Since the AOI of the wing references from the Datum (??) The Cub was designed as a trainer. I am building a Wag Aero 2+2 . Also the tail angles and engine thrust line. What was the outcome? The aircraft has a simple, lightweight design which gives it good low-speed handling properties and short-field performance.
CG may be an issue if you are stating 4 to 4.75. First Lady Eleanor Roosevelt took a flight in a J-3 Cub, posing for a series of publicity photos to help promote the CPTP. $95.00/hr . There is no washout in the tips and I am using differential in the aileron throw. It's a reference to the bottom cord of the wing rib. 0000016498 00000 n <> "Ask and ye shall recieve, Seek and ye shall find." :) :) Jerry. Hi Rick- what is the marked balance point on your plans, just for reference ? I think Wingie's just making sure that some neophyte doesn't misconstrue our "thinking aloud" and hurt himself. Run the trim all the way up and all the way down checking both ways with a Smart level.
