hi to all
what is beter for 3d
thw cmp katana 140 OR the cmp extra 300 s 140 74" tow of them with moki 180
thanks

Personally the Katana would be better. Most Extras will do 3D but do not have the massive control surfaces that are rquired unless you get into the really higher dollar planes. There are a few exceptions but the Extra is generally a very good precision aerobatic plane

Now the Katana on the other hand has the big surfaces.

I haave a H9 Funtana 90 that is a direct copy of the Katana I started mine with an OS91 then an OS120 pumped then went to a YS110. The YS110 makes this thing a 3D monster.

It's whole function in life is to do 3D well and it does it well, very well. Properly power a Katana will do the same as will an extra but not as well

These are my beliefs and I could be wrong but I own both a 1/4 Extra, and the Funtana and both 3D but the Funtana beats the Extra hands down

Katana!!

to bill
i saw the katana and the same sureface at the ail and ele and ruder and the wing area is a little bit less

I have both and the Katana is the better 3D plane, the Extra is better at precison flying

Had!!!! a GP 300 extra with OS 120 on it, it was ok as long as you keep the air speed up. But if you slowed down like you will need to for 3D it had a lot a bad habits, tip stall, almost no control until you gained some speed. I started getting into 3D and was doing a blender and got to low and (THE END)

sorry i asked about GSP(gaiant scale) extra 300 not a great planes one
