I received the Extra last week and started building and faced some problems with it that needs some attention.

I noticed that the motorcage (build up from the separate wood parts) is situated too low, when inserted inside the rectangular slots. Then , the hole in the motorplate is not exactly on the same height as the middle of the motorcowling.
I inserted the motorcage in the slots but did not shifted it down. I gluid it in place with 5-minute epoxy and some small , thin squared plywood.

Furthermore, I bought 4 small and light servo's Graupner C1081 which only weigh about 6.5gram (0.22ounce). Unfortunately, this servo is about 5mm (0.2inch) higher then eg. a Hitec HS-55. Now I got a problem when using it for the rudder. The difference in height (moving the hinge of the servo further outside of the airplane) caused that the rod (connected to the rudder) limited the downwards movement of the elevator rudder. So I replaced that servo with a GWS with less height. Now the space between the rod and the rudder is still , but might be enough. Flying with it will tell it.

Also, I did not put the enclosed aluminum rudder hinges with the steel rods on it , since it is well known that a metal-to-metal contact (vibrations) can cause high frequent glitches that can disturb the radio frequency's.
Instead I mounted the hinges of a Shockflyer and epoxy'd them in place (first removed the foil !) I made some very small holes in the surface that is glued on the balsa to make sure of a 100% guaranteed connection that will not get loose .....
There's no play on the rudders and while the rods are from 1.5mm (0.06inch) carbon, instead of steel there's also a weight advantage ! I hope it is strong enough during high speed maneuvres.

Last but not least I found that the covering of my Extra was very bad, for sure at the side of the fuselage where it's bubbled and since I don't have a covering Iron (I know I'm an ARF typ'o guy ...) ........
Maybe the coverring issue is caused during the overseas shipping (I'm from the netherlands)

Did anyone faced the same problems ?

I bought the Hacker A30-28S and X-30 controller for it, including 3 APC E props (10x5 / 10x7 / 11.5.5). Got it straight from the factory in Germany, it was relatively cheap ; combo price including shipping and 11% discount : 144Euro (=170U$) and 2 years guarantee. Could not find it cheaper anywhere. Besides taht Hacker did a really good job; the motor included two prop adapters, backmounting aluminum plate, solderred connectors on both the motor and esc and all the hardware in the box !
Anyway, I hope this set-up will give enough power.

A still have to glue-in the wings which will be a tough job I guess so the story continues ....

Anybody else had some problems with braking wingspars ???
