Good choice.

RE: MODEL TECH 2M REMEDY
 

thats my second choice first is COGNAC

DON LOWE did a study in RCM about 20 years ago about how to delay the onset of flutter we can't prevent it all together but only push it to a higher speed so if the plane won't go faster we controle flutter
There are warnings in the instructions about flutter why increse the chance of it happening

RE: MODEL TECH 2M REMEDY
 

F-16's and Pylon Racers are intended to go fast. Pattern planes aren't. When I went to my first pattern contest many years ago, I questioned why all the planes had blunt trailing edges, and was told that it was to improve response at low speed. Since then, I have also heard the flutter reason. The reason I have heard that makes the most sense to me is that it makes the plane draggier without affecting airflow over the flying surfaces to assist braking on the down lines.

RE: MODEL TECH 2M REMEDY
 

lots of reasons pick one and go with it I won't change this plane

RE: MODEL TECH 2M REMEDY
 

I hope my Remrdy to arive in a few days and maybe i'll post some photos I'll go with my MVVS160 and see ...

RE: MODEL TECH 2M REMEDY
 

Lots of different theorys out there . . Pattern planes have had razor sharp TE's through to the current trend of thick TE's . . and flutter hasn't been a concern with any of them. Sealing the hinge gaps, correct linkage geometry and servo choice, is considered the appropriate method of handling flutter. 3D throws are a 'flutter' concern, particularly when using analog servos (not recommended), as small amounts of servo travel are used to control large surfaces for general flight (i.e. low servo resolution).

The attached pic is of Gerhard Mayr's own design . . it finished 5th at the World Champs, so I guess thick TE's work as intended for him. Definitely most new F3A designs do not have thin TE's and the rudders are surprisingly thick.

I would just build it as it is, and wouldn't bother sanding the TEs down . . doubt you would notice any difference in flight.

pressure drag is cool [8D]

RE: MODEL TECH 2M REMEDY
 

Anyone think of prop cavitation ? I am not an aerodynamic's expert, but years ago, Don Lowe and Dave Brown were talking about thicker squared off trailing edge's. Lot of experimentation then.

These "gimmicks" are just another way to get your attention. As I have said before, no matter what you come up with or do to your plane, "you still gotta fly it!" Regards___TNWalker

RE: MODEL TECH 2M REMEDY
 

Do you guys think that an OS FS200S will match this plane?
I can get one from Lindinger (Austria) at €179. Offers usually do last only a few days in Lindinger.

Gerhard Mayr DID fly his Osiris well, Some people had commented that his style was the the most accurate of the worlds.

Gimmick? Could be....

RE: MODEL TECH 2M REMEDY
 

Renegade, Gerhard Mayr has the "ability" I spoke of earlier AEB his showing at the World's. Years ago, I witnessed a
14 yr old, by the name of Chip Hyde, wear out a number of so called F3A flyers with an airplane that you or I would characterize as a POS by today's standards.. So, this is what I am talking about! Natural Ability. Regards___TNWalker

RE: MODEL TECH 2M REMEDY
 

Renegade, let me also add, there is a young F3A flyer by the name of Joe Szczur here in the US that is one of the best current examples of what we speak of. He, like his Dad, has the Natural Ability. Joe will be a force to reckon with in the
near future. BTW, he is not the only one. There are several really young flyers throughout the ranks that are currently
doing "surgery" on someone, somewhere at a contest as we speak! Regards___TNWalker

the os 200 would fit in the cowl weight might be the only consern it would be awsom power though

RE: MODEL TECH 2M REMEDY
 

Go vertical,
Thank you for your quick answer.
Modeltech recommends a Magnum FS 120, which weigths only 3-4 oz. less than the OS 200.
I am in doubt about the muscle of the Magnum for such a two meter plane.
If, as you say, the OS will fit on it, I´ll order my Remedy immediately, hoping that the extra weight will still allow good flight performances.
I´ll let you know about the results.
For sure she will go vertical as a rocket!

RE: MODEL TECH 2M REMEDY
 

here are some pics of my engine instalation

RE: MODEL TECH 2M REMEDY
 

Hello there !!i just got mine and i started it yesterday ! The only think i m concerned is how to instal the MVVS 160 + tuned pipe (it must be instaled at about 200 degres if i want to have the pipe under the fuse):eek:

RE: MODEL TECH 2M REMEDY
 

aandreas
putting a tuned pipe on a 2stroke engine is going t be very diffacult as you can see the drop from the exaust port to the pipe chanel is 3in. so it will require a custom header I don't want to go that rout

RE: MODEL TECH 2M REMEDY
 

yes it is quite far from the exhast port but if i put the motor sideways and down i thnk it will be ok The only negative about this is that i ll cut the cowl ..

RE: MODEL TECH 2M REMEDY
 

aandreas
post pics of what you come up with

RE: MODEL TECH 2M REMEDY
 

well i did some work ... and the most important i put the engine at the wright spot ...
im finised with the higing and the throtle servo ..thats for the moment

RE: MODEL TECH 2M REMEDY
 

the hardware for the controle horns for this plane is junk I will change it to more sturdy hardware what they supply is only about 4-40 realy light for a plane this size

RE: MODEL TECH 2M REMEDY
 

hi! i ll use the hardware suplied ...i think its fine ..!(i had an ULTRA RC GILE 202 about the same sise that came with more or less that kind off hardware and it was just fine ....so im sure its ok!
