Yup, I agree with jaka. Trim the corner off of the horn and you'll be ok. Remember this if you start adding 'shims' then you may run into a problem with your horn retaining screws not being long enough. Jaka has given me good advice before and I am sure he will do the same for others. Thanks Jaka. I may have not mentioned (Jaka) it but my sonic 500 did fly really good and my throws ended up closer to yours than anyone elses. I have a Nexstar too and mine will do almost the same thing. But during installation I kinda figured in for this and had placed my horn just a bit further back. The rudder is not too thin nor is the fuse too thick. It is all good. The Nexie is an odd craft in some aspects but with some mods is a quite decent plane. I think it is a large plane for the engine size but it does quite well with it. Anyway, don't get too carried away with the rudder on it. I seldom use a rudder. Only during certain manuevers and during landing and takeoffs. I may be a poor pilot who knows. I think if you trim the corner of the horn without getting too deep you'll be just fine. Main point being you dont want you servo working too hard and draining the battery down too quick. Remember this about the Nexie and you can try it if you don't believe it. If you throw full rudder in flight it will list in that said direction and the nose will drop hard as well. That isn't a bad thing if you loose aileron control but it can be unnerving to a student pilot. I have had models that would actually appear to fly sideways with full rudder and they would not drop a wing or the nose. I have always considered these type of planes to be good designs.

Good luck with it dude,

Edit to add: Before you fly that thing you may want to smooth out the wrinkles in the covering with a heat gun. It will still fly without doing it but it will give a better overall impression if you take it to the flying field without all of those wrinkles. That is just my opinion and it is probaly worth crap....
