Wait until he gets into bigger stuff. Dropping $2500 on a plane is not uncommon. Heck, I just completed a 33% WH Edge that ended up at $2500. I'm almost done with a Comp-Arf 2.3 and will be close to the same amount. I have a NIB Comp-Arf 3.0m Extra 260 that the airframe alone is as much as I have paid to completely assemble any plane I have owned up to this point. I remember my first big one, I nearly passed out after placing the order at TBM for all the little goodies...It adds up quick

With bigger planes there is that nervous factor for a little while. When I take a big one up for the first time, I shake pretty badly for the first couple of minutes. I've gotten to the point some times that I had to land because I could not keep any resemblance of control. 99% of the time when I get like that, it's not that the plane is seriously out of trim, it's more me. Being nervous is also a good thing as it can help to make you more careful but of you don't recognize it quick enough, it can get so bad that control if compromised. It happens to everyone at some point and you just have to learn to catch it.

I'm gonna end up in bankruptcy court if I do not stop but ya know, It's not a bad way to go...

ricomari,

I did see your post, had a answer all typed out the other day and ended up having to take my sister over to the emergency room and by the time I got back I forgot all about it.

Anyway, I have seen 5645's come with a tiny bit of slop and in other cases I've seen no slop. As long as they are returning to center everytime and when you plug them in, you cannot overcome the torque with your fingers unless you really push it then I'd guess you'll be fine.

He over to the radio manufacturers support forum for Hitec and asked them, or better yet, give them a call. I'm glad to read you are dumping the ST125's. I think JR did a bad thing with the Sport servo series. A lot of people are using them in GS planes and loosing the plane because the torque values match the requirements but the servos cannot take the stress of a heavier plane and it short ordewr will wear out.
