Well, I finally started on my Sonic. It is going together quite nice! Couple things:

1. I am definitely modifying the wing attachments, those plastic screws are terrible. Gonna go with the stud and wingnut approach mentioned a couple pages back. Anything I should be aware of?

2. Was anyone else's aluminum tube that goes in the wings too long? Mine seems to be about 1/4" too long. Both wings will not fully seat to the fuse, you can only do one or the other.

Thanks for any help!

Yep, wing tube too long. I trimmed mine. I also glued a wood dowel inside the tube. This makes the wing tube much stonger. I only used a dowel half as long as the tube. I centered it inside the tube. The most critical part of the tube is on each side of the fuse where the wings but up against the fuse.

Thanks for the help! I will plan on gluing the dowel inside as well!

Not much action lately here on the Sonic thread. But I've been keeping mine busy. I fly it several times a week - still having a lot of fun with it.

Several posters here were very concerned about the HXT 900 9g servos I have been using on the plane. They don't even come close to meeting the minimum torque specification, so I have been watching them carefully. Recently the rudder/steering servo began buzzing and not centering consistently.

So I changed it out for a used Futaba S3004 I had in the servo bin. Kept the HXT's on the ailerons and elevator but everything is quiet and smooth now. It added 28g to the plane but maybe it was an "ounce of prevention" that was worthwhile.

134 logged flights ......and counting.

It's a great plane. Had mine out a couple times last week. Don't remember if I posted or not but I put a little larger motor on it. Still flys great and the added weight in the nose is a plus.

I still have an old version in a box I bought as backup, I haven't flown mine for quite a while, I have about 25 planes and never seem to get to the Sonic, but whenever I do, I kick myself in the butt for not flying it more often, it is a great little plane. I think I prefer the wings in 2 pieces over the new style.
