Extras...what are the differences?
 

What are the differences between the Extra 260, 300, and 330? Advantages vs disadvantages?

RE: Extras...what are the differences?
 

the 260 is a single place airplane. the 300 and 330 are two place. The 330 has a bigger engine than the 300 (talking full scale here).

RPool,

In addition to what IFlySlowPlanes said, the Extra 260 is an older version of the 300 or 330, and has a slightly higher wing location on the side of the fuselage. BTW, just because the 260 is an older design, don't think it doesn't fly as well as the 300 or 330. Personally, I prefer the 260 to either the 300 or the 330.:D

Here's a reasonably good explanation;

Be aware that all models, or at least the good flying ones, have some modifications from being true scale in order to make them fly better. That difference is best expressed by the examination of Reynolds numbers, but suffice to say that is the reason that you are allowed a 10% deviation from true scale on models used in IMAC scale aerobatic competitions.
