Piper Cub Buyer's Guide: Vintage J-3, PA-18 Super Cub or a Modern CubCrafters?

"Cub" covers three different buying decisions. The J-3 Cub is a 1938-1947 vintage two-seater of about 65 hp. The PA-18 Super Cub is a heavier, up-to-150-hp backcountry and float airplane built from 1949 into the 1990s. Modern CubCrafters airplanes are new designs from a different company, some sold as light-sport or experimental aircraft and some type-certificated. Prices, financing, insurance and even which pilot certificate you need differ across the three, and the FAA's MOSAIC rule changed that last part.

Decision rule: if you'll fly mostly for fun from grass or paved strips and want the lowest total cost, a sound J-3 with good fabric and a documented strut history is hard to beat. If you'll use the airplane for backcountry, floats or hauling, buy a PA-18-150 and put your effort into the modification paperwork. Choose a CubCrafters airplane when you want new-airframe performance and support and can finance a much larger loan. The annual budget for a Super Cub is on the Super Cub cost-of-ownership page; for a similar vintage two-seater, see the Aeronca Champ cost page.

What did MOSAIC change for Cub buyers?

Under the old light-sport definition, the J-3 qualified for sport pilots but the 1,750-lb Super Cub was too heavy under the old weight limit. That weight limit is gone. Since October 22, 2025, sport pilots may fly airplanes whose clean stall speed (VS1) is 59 knots CAS or less at maximum takeoff weight, in any airworthiness category, with up to four seats but only one passenger. The PA-18-150's published stall speed is 37 knots with flaps down, so most Super Cubs, and many modern Cubs, now fall within reach of a sport pilot. Confirm VS1 in the airplane's own flight manual in calibrated airspeed, especially if it has a gross-weight STC.

The new light-sport airworthiness category that took effect July 24, 2026 has no weight cap and allows up to four seats, a VS0 up to 61 knots and speeds up to 250 KCAS. CubCrafters announced a turbine-powered Carbon Cub ULT aimed at the MOSAIC framework in July 2026, with initial deliveries planned for 2027 (General Aviation News); as a turbine, it's outside this site's piston focus. For how these rules affect loans, see MOSAIC light-sport rules and financing and the light-sport aircraft buyer's guide.

What does a Cub cost to buy and finance?

In September 2026, J-3 Cubs on Barnstormers asked about $39,000 to $89,995 (a float-equipped airplane at the top), most between $45,000 and $62,000. PA-18 Super Cubs on Controller.com asked about $81,981 to $405,000, most between $115,000 and $215,000. CubCrafters listings ran about $164,900 for a 2007 Sport Cub, $220,000 to $244,900 for 2011-2015 Carbon Cubs, $299,000 to $349,900 for Carbon Cub EX and FX experimentals, $299,900 to $549,900 for 2016-2024 XCubs and $409,900 to $495,000 for NXCubs. Treat these as asking prices and verify with Vref or Aircraft Bluebook; contact CubCrafters for new-aircraft pricing.

AOPA's lenders don't impose an age limit on piston singles, but aircraft built before 1960 may need 20% down and a shorter term, and 20-year terms apply only to loans of $75,000 or more (AOPA Aviation Finance). Airplane category matters too: FLYING Finance's September 2026 rate page starts certified piston loans at 7.01%, MOSAIC light-sport at 7.71% and experimental or kit aircraft at 7.78% (FLYING Finance). As of September 2026, piston loan rates quoted by major aviation lenders generally start around 7% and run to about 10%. The examples use an illustrative 7.75%.

Loan amount $136,000. Principal and interest only; excludes insurance, taxes and fees. Illustrative, not a quote.

A J-3's fuel bill is small: at an assumed 4.5 gph and the AirNav national 100LL average of $7.24/gal (September 2026), about $33 an hour. Check the owner's logs for the real figure. For experimental Carbon Cubs, see financing experimental aircraft.

What should you inspect on a used Cub?

Use a mechanic who knows fabric taildraggers, and add these items to the general pre-buy inspection checklist:

Source for the strut AD: Federal Register, AD 2015-08-04. Have your mechanic run the full AD list for the airframe, engine and propeller; see reading aircraft logbooks.

What training and insurance should a Cub buyer expect?

You need a tailwheel endorsement for all but the NXCub (14 CFR 61.31(i)). There's no verified 2026 Cub premium benchmark; underwriters weigh tailwheel time, time in type and how the airplane will be used (floats and off-airport work cost more to insure). The Super Cub cost page budgets a labeled assumption for an experienced tailwheel pilot, not a quote. BWI reported in May 2026 that pricing for experienced private pilots of personal-use pistons is "generally stable" (BWI). Lenders require hull coverage naming them as loss payee; see aircraft loan insurance requirements.

First-year ownership notes for a new Cub owner

1. Get tailwheel training in your type, and on a J-3, learn safe hand-propping from an instructor.
2. Put the strut AD due dates on a calendar unless sealed struts are installed.
3. Hangar it if you can. Sun and weather shorten fabric life.
4. Keep every 337 and STC together; the next buyer, insurer and lender will ask for them.
5. Register the airplane. Registration is valid for seven years and costs $5; the "pink copy" works only within the U.S. until the certificate arrives.
