I need to practice my IMAC sequences as much as possible. I thought that the 2x2 might be practical as a daily trainer, if the flight characterists are good. I just don't want to get a dog. Can't find much in the way of reviews or opinions on it though. Maybe it hasn't been a very good seller for Comp-Arf and they're trying to unload their inventory. Dan

The C-ARF 2x2m Extra flies very nice for its size. It does all the 3D stuff, but - off course - needs a bit more attention than a bigger plane.

Here are some pics of my Extra: http://users.tsunamihost.ch/~swissmo...mpositearf.htm

There is absolutely NO SIZE REQUIREMENT in any IMAC class. The 2x2 is not legal beacuse it is out of the 10% limit for Scale Dimensions. I know Cardens are stretched out to the 10% limit for better tracking. Since this plane has a way longer fuse than it should for its wingspan (more that 10%) it is not IMAC legal.

It would only be legal in Basic if its outside the 10% rule.

There is a size requirement in anything above basic. it has to have 80" wingspan! You could fly a foamy in basic too! Vid not trying to challenge you but can you prove it to me in writing that the 2*2 is illegal for imac?

[sweetpea]

80" is IMAA rule not IMAC rule.

No one is enforcing the pilot/dash rule since next year it disappears. Though I've heard your canopy must be see through (tinted is ok, just not opaque) for next year

[Vic3D]

OK Youngflyer, here is the link to the IMAC Rule book:

http://www.mini-iac.com/DesktopModul...id=57&tabid=90

Let's start by reading rule 3.2 in page 7. And I quote "The Basic class is open to all competitors with a biplane or monoplane aircraft. There is no minimum size requirement for any class."


Now let's read rule 6.5 in page 11. And I quote "Fuselage width, height and aircraft planform or any other variations shall not exceed 10% of scale, with the exception of airfoils and size/shape of control surface within the scale outline rule."


With that said, let's find the dimensions of the Full Scale Extra 300. According to the www.extraaircraft.com website, the dimensions are:

Length: 274 in.
Wingspan: 291 in.

Now lets look at the Composite ARF website for the 2x2 Extra dimensions.

Length: 78 in.
Wingspan: 78 in.

Ok so lets get the Composite Extra 2x2 Scale Percentage in reference to wingspan:

78/291= 26.8% Scale.

Now let's bring down the Full Scale Extra dimensions down to 26.8% scale.

Length: 274 in x .268 = 73.4 inches long
Wingspan: 291in x .268 = 78 inches wide (wingspan)

Anyone care to do the deviation-from-scale-percentage math for the fuselage? My brain is fried.

Vic

[youngflyer]

did they do away with the 80" rule?

[Haggy]

Does anyone know if Comp-ARF will be releasing a clear canopy for the 2x2?

Cheers

18.35% (I think) anyone else???

[Jaybird]

I would be really suprised if someone got turned away at an IMAC flying a Comp 2x2. I didn't see any measuring tapes at the one I competed in.

[Jamieman]

I guess if you started cleaning up in advanced or unlimited with it the tape might come out.

[Haggy]

Go the "small" planes in Advanced or Unlimited!!!! Mix it with them!!!

[Imac Kiwi]

Getting back to your original question. Bogan has one flying here with a DZ 160. It tracks nicely for sequence work and 3D's well.

So, you will be keeping me company in advanced next year Haggy??

[Haggy]

Nup, just would be happy to see a "small" plane mix it in the higher categories...
