This is where Aeroworks takes some poetic license with their version of the 260 in that they include the servo tabs which are NOT part of the stock 260 design.

Sorry Jim but the L designation is for length and refers to the two seaters. The 300 series are all low wing. From the Extra web site
"The EA-300SP is Extra’s single-seat version of the EA-300LP" The 330 designation is not an Extra aircraft designation but was added by the first pilot to put in the 330hp Lycoming. You're right about the elevator tabs, and this plane is constantly changing.
Isn't this fun

My plane agrees with Lee. 330L is the 2 seat version. Wish it had the extra horsepower he is refering to.

But your also has lower wing position then the original 300 shoulder wing.

OK guys, I just got reamed for not replying to your inputs ( even though I did reply) so here goes....

OK u crowd I guess Ihave to 1. leave my wing alone, 2. add a second seat.

Well sorry I asked!!

Thanks again,

Ray.

Oh BTW Jim, if I put a big round cowl on it woiuld it be a Yak 300L?

OK Lee I visited the current Extra 300 web site and they do not even mention the ORIGINAL Extra 300 but found this photo on the web.

So we are ALL correct :P :P :P :P :P



See it's a plain old Extra 300 and it is 2 seater and shoulder wing the 300L is 2 seater but low wing as well and the 300S and 300SP are single seat low wing.

Rick I wish I had Extra Yaks just laying around but I currently only have one.

Is it worth the effort to relocate the wing higher seeking axial and more coupling free aerobatics? Mod not hard to do on this one. BTW did the prototype design really change or is this an IMAC thing?


Its more of a fun/practice/backup plane as I will be flying a Fontana 100 in Basic this year..just starting out really.

The L is a two seater airplane. The wing was placed lower to accommodate comfort on longer flights between events and so the wife could come, no joke.
Either way, it only makes a difference to full scale. Perhaps an argument could be made about rudder coupling and mixes but it is entirely dependant on your preferred cg. Where you put the CG on your plane determines everything from thrust line, to differential, to mixes. The Sukhio's have low wings as do some yaks and all Caps. Edges have a mid wing as do some Extras. It is all setup!!!!!
Leave the wing, learn trimming!

"The new Extra 300L (low wing) has received FAA and Transport Canada certification in the normal and aerobatic categories. Similar to the 300, the "L" model has the wing lowered for improved visibility and ease in the installation of full IFR instrument panels. The main fuselage structure, wings, tail etc. are similar to the current 300 which is still in production. The seats in the 300L have been redesigned to increase comfort and may be covered in leather as well.
A number of small improvements are also incorporated in the design including all composite side and belly panels. Flight characteristics are similar to the current 300 in all respects. The 300L displays improved snap roll characteristics, both inside and outside, and the rate of roll is slightly faster than the current 300.

It was designed by Walter Extra, a retired aerobatic pilot, in 1987. The Extra 300 was developed from the early 80's Extra 230 but the wing is no longer made of wood. The aircraft is based on a welded steel tube fuselage covered in fiberglass and fabric. The mid-set wing has a carbon fiber composite spar and fiberglass skins. A symmetrical airfoil, mounted with a zero angle of incidence, provides equal performance in both upright and inverted flight. The landing gear is fixed taildragger style with composite main legs and fiberglass wheel pants. The powerplant is a fuel-injected Lycoming AEIO-540 which produces 300 horsepower (224 kW).

The Extra 300 is stressed for +/- 10 G with one person on board and +/- 8G with two. Some Extra 300s are registered as Experimental Exhibition aircraft in the U.S., while others are certified in the Aerobatic category[1].

The Extra 300 has given rise to several models: the 300S, 300SH, 300SHP, 330, 300XS, 300L, 300LP, 300SP, and 300SHP.

The Extra 260 was based on the Extra 230 with a a 260hp AEIO-540 engine, a 300-like wing, and the predecessor to the 300. Only a few were made.
The 300S is the (S)ingle-seater version, with a wingspan reduced by 1 ft 7½ in., and fitted with larger ailerons.
The Extra 330SX was a custom development of the 300S with a wider-chord rudder, a larger elevator, and a more powerful Lycoming AEIO-580 powerplant producing 330 hp (246 kW). Some 300S were sold with the "bigger tail" of the 330SX
More Extra 300L ("L" for low wing) aircraft have been produced than any other model. Its wing is mounted at the bottom of the fuselage, with its span reduced from 26 ft 3 in (8.00 m) to 24 ft 3 in (7.39 m). Improved ailerons boost the 300L's roll rate to 400 degrees per second. All 300Ls are fully certified under FAA and European Joint Aviation Authorities regulations.
The 300LP ("P" for performance) is a reduced weight version of the 300L, re-designed for better performance in competitions and airshows.
The 300SP is a performance version of the 300S single-seater. Weight was reduced, and the tail of the 330SX installed [2].
The 300SHP (HP=High performance) is a yet-uncertified version of the 300SP with an AEIO-580 engine.
The Extra 300SR is a modified aircraft using a specially designed high-lift wing for the Red Bull Air Race World Series. It made promising debuts in July 2007.
The Extra 300SC will be a modified 300SHP which will use a new wing with better roll rate and easier roll stops, designed specifically for competition.
