Hello:

I'm new in flying giant planes. I would like to bild my first big plane with a gas engine and I have a lot of questions.

I'm thinking in an Extra 330 26% ( http://www.camodel.com.ar/modelos/e...30-26-30ing.htm ) with a CRRC-PRO 45 cc engine ( http://www.rcuniverse.com/market/item.cfm?itemId=282834 ).

Do you think it is a good combination? Do you have any comments about the plane or the engine? I live in Argentine and this engine is a very affordable option (U$S 320) and comes with electronic ignition and muffler. I saw that a DA50 or a Zenoah are much more expensives and my budget is really small.

The plane also needs 7 high torque servos (7-8 kg at least). I was looking these ones from Hitec but I can't evaluate the diferences:
HS-755HB: http://www2.towerhobbies.com/cgi-bin...?&I=LXGLN4&P=7
HS-755MG: http://www2.towerhobbies.com/cgi-bin...?&I=LXMYH3&P=7
HS-805BB: http://www2.towerhobbies.com/cgi-bin...&I=LXN610&P=ML
Could somebody explain me what are the diferences and wich one is better?

I have a Futaba 6EXAS radio with a FM receiver. Do I need to go to a PCM receiver? The radio came with a 4.8v 600 mA NiCd receiver pack, will I need more powerfull bateries? Is there any problem with the receiver and the current used by the bigger servos?

Thank you in advance...

Pablo.
