I am thinking of buying a GP Christen Eagle II. I live in Brazil and here we don´t have much information about this model.

Could you help?

1 - Is GP Christen Eagle a good model for manouvers? I Know it is not a 3D model as Funtana is, but could I compare Christen with an Extra model?

2 - In your opinion what is the best engine option?
2.1 For Best performance
2.2 Best value for your money

3 - Do you know MVVS engine is it good?

4 - Christen or Ultimate or Pit Special, do Know de diferences among them?

Lots of questions for one post, Ghion - but I'll take a stab at your main points.

The GP christen Eagle is a beautifull scale plane but leaves MUCH to be desired as an aerobatic platform. In comparison the Ultimate is a much better flying plane. You will need at least a 30cc (1.8ci) glow or 40cc gasoline engine for it. My recomendation would be 2.1 glow or 50cc gas.

Use the search function here on RCU and you will find a ton of useful info on this plane.

For what it's worth, I was so unhappy with the flight characteristics of my GP Eagle I quickly sold it. Pity because it really is a gorgeous airplane.

Luvbipes, Would you be so kind as to tell me a little more of the dissapointments from your CE please. I really need to know, thanks, MM

RCU have a review of the plane here: http://www.rcuniverse.com/magazine/a...article_id=470

I had one with a DA-50. It had good power but was not unlimited at 19#. As with all short coupled planes, you have to be on top of this one. It flew beautifully but was a handfull on takeoffs and landings. It flies like a scale bird. Back off of power and you will definately notice the weight.
The Christen Eagle is a spinoff of the pitts family. Designed seperately and yet with many similiarities. The Ultimate was designed to overcome alot of the shortfalls of the Pitts class. Its much more stable in all flight modes.
If you do not have any Bipe experience then you should look towards the Ultimate.
Good Luck!

Mike, as stated above, the GP Eagle is short coupled (distance from CG to tail), it seems GP favored scale outline over flight performance. The plane has heavy pitch AND roll to rudder coupling, which makes knife-edge and point rolls challenging. Can a good pilot make it perform? Sure, but I was working the sticks a LOT harder than with my others planes just to keep it on the intended flight line.

I have flown extensively 3 other biplane designs including the 1/4 scale Dave Patrick designed Cermark Pitts S2B and Goldberg Bucker. Though one size smaller (designed for 120 2-strokes) both these planes flew far better than the GP Eagle.

Yup, that seems to be what it amounts to. Well, It's my own fault for jumping into it without first researching first. I think I'll just finish putting it together then take it down to the LHS and sell it. Damm my stupidity for not checking this out first. [:@][:@][:@]. MM

If you want a plane that's gonna be a true aerobatic platform, I think that's the right decision. On the other hand for someone that wants a great looking plane w/ which to do the occasional loop/roll/spin, then it would be a fine plane. Depends what you want out of it.

FYI, I recently had the opportunity to reconfirm my original impressions when a friend let me fly his ZDZ60 powered GP Eagle. It flew much as mine had and I still think I was right to sell it.
