Problem building the H9 Alpha RTF
I've recently purchased the Hanger 9 Alpha Trainer RTF kit.. I'm just getting into the hobby, and have never built anything like this before. Suffice it to say.. it has taken me a little longer than the suggested hour to build this thing, as I have had to go and get a number of tools (haven't been into modelling up to this point.. so I didn't have much tools wise).
In any case.. I pretty much have it together now.. but there are a couple of issues. Most critically, when I (or a servo) deflects the left aileron up.. to approximately 50-60% of what I believe is its intended travel.. there is a "clicking sound". You can see as you move the surface that there is a tension building up and it releases with this sound. The aileron will then continue to move to maximum up deflection normally. If I release it, it returns to 0 degrees without any noise. The other aileron and all the other control surfaces do not make this noise.. so I know it isn't normal. I suspect that some piece of the push rod or hinge is catching on something and making a bit of snapping noise.. but from what I can see.. there is no way to service it without opening the wing.. Which I really do not want to do. But if I have to, I would greatly appreciate some advice as to how to approach this problem.. and what additional tools I might need. There is a training session at my local club on Tuesday nights.. and I was hoping to get my model into shape to particpate.. but I know this is going to be a grounding problem if I can't fix it. The other thing I am curious about.. and doesn't appear to be directly addressed by the instruction manual, is: should the servo's be making any noise when both sticks are at neutral? When I first turned the model on.. there was a slight wirring noise. I'm assuming it is my goal to eliminate this by trimming the sticks? Thanks in advance for any help you guys can provide. pdv |
RE: Problem building the H9 Alpha RTF
It sounds like a servo might be binding a little bit. The best advice at this point that I can give you is to take your plane to the field on the Tuesday training session and let an experienced flier look it over. He will show you how to fix the servo, measure the control surface throws and generally give you some tips on plane set up. Take the manual along with you. As for what tools you need I recommend again to talk to the trainers. They can tell you what you really need so you won't waste money. Starting out I wouldn't buy a lot. Chances are someone at the field will let you borrow something if you don't have it.
I could sit and tell you what to do but it will sink in better if someone goes over it with you and shows you hands on how to set your plane up. WCB |
