Friends,
Even with the added bottom rudder hinge and having set up the servo travel for full travel to either side in the elevator cutout, I still see very poor rudder response as far as yawing the tail around during power-off flight on my Phoenix 2000. When the high speed flow from the running motor is being pushed past this stock rudder, the deflection of the rudder does have some effect... but while gliding with power off, it takes some time for this glider to respond to rudder deflection. When hunting smaller thermals with my Multiplex Easy glider (& also with an extensive variety of other gliders which I have built,own, & occasionally fly), I'll typically use cross-controls of rudder & aileron; the rudder controls the turn radius in a tight thermal, while opposite aileron input keeps the wing's bank angle flattened out to maintain altitude more efficiently. The rudder on this Phoenix 2000 is slow to provide a response. The much larger tail group of the Evolution version that's designed to fly with the 2.6M wing might be really nice. (And maybe I just need to get comfortable with the response that is available form the stock rudder. VIKING |

I stiffened my rudder with a curved carbon strip from under the horn to tip, and was going to add a bottom hinge, but don't think I'll bother now after hearing your report.

I hinged the rudder on the bottom side too and I put a couple of carbon pieces in order to stiffen the rudder too.
I don't notice a so big lack of authotihy by the rudder. It seems to do what it's built for and everything is fine, on that aspect, by my side. I have to admit that I don't find any benefit by turning with crossed commands (and I don't think there are some) so it's something I don't do. Anyway... I think that if you need a so big rudder movement to contrast a so big aileron movement there's are some "excesses" in what you are doing...and it's better not to have a bigger rudder that, in my opinion, should be used for other things. :-) |

Richard,
everyone's entitled to their opinions. I've built & flown gliders since 1982, & started building E-powered gliders back in '83 & '84. The stock Phoenix 2000 rudder design / setup, with full travel, is only marginally effective; a newbee getting this kit & not understanding this would be at a distinct disadvantage. As one example, while it may cost a few more bucks, both the design and in-flight performance of the stock Multiplex Easy Glider are better than the Phoenix 2000. The two-piece wing installation is quick, simple, & very effective- mine is still performing great after many years of service. With the larger Evolution tail group, this may well be a different flying glider.... I hope so. Let us know! (Below is a photo of three of my more recent designs; all have precise quick rudder response as well as clean aileron response on their flat-built wings with elliptically up-swept wing tips, offering excellent in-flight stability and responsiveness.)

Viking,
obviously I respect your opinion and your experience. Anyway, I think it's a very good thing to add my impressions because... ...I've had the EG Pro too and I can so compare the two "birds". The EG is slower and I didn't notice anything better, in flight, than the Phoenix 2000 one. The Phoenix is a little bit faster (loosing a little bit of energy less, while diving it down) and I think it can "compensate" the different wing profile with the presence of the flap that make you change camber dinamically (even if I don't think we are talking about big difference, in caso of EG Pro and in case of Phoenix cambered with flaps). ![]() Nothing to say about quality of material/construction of the EG (but it would be crazy to sell the EG at a higher price if the quality were not better than the Phoenix): you're right, EG material seems to be much better. This is even the opinion of other persons I exchanged opinion with: EG Pro - Better quality/more durable, Phoenix - Absolutely valid for the Price, "better-looking" and a little bit faster but... cheaper quality. I wanted a "foam" glider with flap (even just to control the descending angle for landing) and the Phoenix is fine for this, considering (it's important to notice it) that it seems to do (not only to my eyes) what EG Pro can do. ![]() I'm very happy about it and, for the kind of flight I practice, I don't miss any further rudder effect... Then... maybe I'll be back after the attampt to make a "Hammerhead" without success and the Phoenix in thousands of pieces. Then you will have another person thinking that the rudder has no effect on this model.

Evolution Tail...
I have the Evolution and easyglider. Rudder authority on the evolution is a problem also. I needed to get used to the poor rudder... meaning at least a half dozen nail biting landings to teach me.. The Evolution needs it's nose pushed down if you want the rudder at low speeds. I know that may be obvious but after the flying the Easyglider for a few years I was spoiled by being able to toss it around in any direction! That being said, I now fly the Evolution comfortably with the rudder in stock form. I would agree with Viking60 that the easyglider is a great flyer. The easyglider does have amazing (surprising) high wind perfomance.. I have had it in 40mph... really.
(with about a 8oz ballast) (easyglider is still together and awesome) I have the Evolution, changed out all the problematic things and like it as part of my fleet.. PS Viking60... Your homebuilt planes are great.. I have my own version of the Flirt built from your specs.. still a favorite. |
