Extra 300s
 

Does anybody know wether the graupner extra 300s is a nice plane, i was thinking about getting it.

RE: Extra 300s
 

The Graupner is a lovely plane, finished very well. The only slight down side is that it is a little on the heavy side. You should be able to loose a little weight by replacing the aluminium undercarriage with a light carbon undercarraige and removing the aluminium control rod guides to the elevator and rudder.

As standard the Extra flys very well and can perform most manouvers. Don't put the CofG too far back otherwise it may be prone to tip stalling, though that is the same for any aircraft of that type.

Hope you get one, they're good fun!

This plane is Neat!!

It flys beutifuly. Nice areobatic plane. Its not as light as a 3d plane.

If you havn`t flown much, a 60 is sufficient, but if you want some more performance, put a 90 2st in it.

Keep the CG on 98mm, and install a 500ml tank. And dont give the elevator more throw than the 8mm specified in the manual, or it will be unpleasent every time you pull full elevator. It aparently stalls the entire stabilzer, and it snaps ;)

Here are some pics of mine..... Ive actualy owned 2, and this is my first one with a magnum GP 65......a little tame, but it flew nice.
This one crashed du to pilot error [8D]

One importent note, is the tail. Aparently there have been alot of horizontal stabilzers that have broken off in flight. Graupner have included a little bag with tail braces, that are a MUST to install. Also, when you have to emove the covering in the tail to glue it onto the fuselage. Dont use a knife to remove it. Use a soldering iron, and melt the covering away, so you dont cut into the balsa.


Here are some pictures of my Nr. 2 model with my webra P-5 91 Aero engine. 14/7 prop

You guys are lucky, the Graupner here (Black Horse) has the boring GP style colour scheme. :(

RE: Extra 300s
 

Just stuck on the checkerd decals...man what a pain.... But it turned out nice enough....

RE: Extra 300s
 

hey SJN will a OS .91 fit in the extra with the stock engine mount?


thanks

RE: Extra 300s
 

Not 100% sure, but my large webra 91 2stroke and my Magnum 65GP fits.....

So why not..... the 91 has the same crank case dimensions as the os 61 right..

RE: Extra 300s
 

actualy, when i think about it, my friend at my field has an os 91 2 stroke in his with the stock mount....so yes, it fits :D

Plane flys much better now [8D]:)
