Thanks for the info.I did it right then,thats good.I do have another problem,i assembled the flybar section and it seems ok.The problem im having is the screw that goes through the flybar to hold it on the shaft is to short.It calls for a 16 mm and a locknut but it wont grab the nut.any suggestions what to do?Maybe a longer screw and use my dremel with a cutoff wheel to remove the excess.

did you see my tips on the other post ,,,,

rod ends,,
if your rod-ends are to tight on their balls simply pop the rod ends on and off the ball a few times to loosen them up,,

servo arm balls and tail grip balls,,
these balls are coated, you may need to be polished the coating off to get your rod-ends smooth on them too,,

washout block,,
if your washout block is tight on the main shaft polish the main shaft with a fine grit sandpaper, I use oil to lubricate the sandpaper, when done you MUST clean the shaft, I clean the main shaft well with rubbing alcohol on a clean rag,,

tail grip ball links,,
if you find these short links are to tight in the pitch plate you can remove the pins, remove the links, and use a fine file to file the edges on the pitch plate (not to much now !!), I guess you could use fine sandpaper wrapped around something flat,, when done clean the pitch plate nicely,,

tail linkage guides,,
do not glue the guides to your boom, take a 1&1/2 inch long piece of black electrical tape and wrap it on the boom where your guide will be located, slide the guide over the tape, then use a hobby knife and cut the excess tape from the sides of the guides,, you will now at any time be able to adjust your guides to properly align your rudder linkage down the length of the boom,,

best tip of all,,
buy another Century heli ..

The instructions called out for a 16 mm.I used a 20 and cut the excess off with my dremel.It looks just fine.cutoff wheels in the dremel set work great.It ripped through it like nothing.Now im working on the landing gear.Is there supposed to be a plastic spacer between the frame and the plastic part of the landing gear.It looks like it in the picture.It doesnt mention it in the instructions though.I put one on each bolt.Its coming along pretty good for a begginner i think.Ahter the landing gear im going on to the tail section.I dont have my radio gear yet but i dont think its going to be a problem installing it later.Im really enjoying building this bird.Its a lot of fun seeing it all come together.Thanks for all the help guys,i appreciate it very much.

Yes there is a spacer there, Ive used the ones that came with the kit, not shure what significance they serve. Ive sence replaced them with some SOFT rubber o'rings I got from Home Depot and they seem to help soften the spool up on hard surfaces.

Ok,im doing ok so far but i have another question if you guys dont mind.On the tail boomIt says to use 3x30mm on the top two and 25mm on the bottom.I think its backwards because with a 25 on the bottom the bolt wont go through the tail servo mount,its to short so i switched them and it seems to be the correct way.Also when the boom is inserted into the hole does it line itself up by itself or do you have to do it yourself?The tail rotor moves when i turn the gear.It looks kind of straight but i cant really tell.

When you push the tail boom into place you can rotate it a bit untill it slides into the little notch it has. it is self aligning.

Thanks for the info.You guys are probably getting mad because of all the qquestions i have.If i get on your nerves just tell me please.I do have another question,i have the tail assembly together and the supports mounted to the frame but it seems the screws that hold the supports to the tail boom wont go through the hole.Is it ok to open the hole a bit with a drill bit?I have a drill bit just a touch larger than the hole and it should give me the clearance i need.Im getting the impression that these kits arent perfect and you may have to make some corrections to make it work.

I find it always easier to help someone if he refers to a specific page/step in the instruction manual that he is having a problem with.

Here, I must assume that you are referring to the step where you attach the tail boom supports to the Horizonatl tail fin clamp. The holes at the bottom are supposed to be smaller because the support struts are attached to the fin clamp using short self tapping screws.

I have assembled many helis in the past 20 plus years and I found the Hawks and Ravens to be among the easiest, requiring minimum (if any) "fitting".

What I did find, is that sometimes they nay have the right sized screws or bolts for one step inside the bag for a relating step...as I have found in other kits also.

Section 9.2 calls for 3mmx8mm self tapping screws with a washer.The screws dont fit through the hole.

Ok,now i have another problem.Section 9.3 which is the top fin mounting section.The problem im having is there is a gap between the fin and the clamp.I have used the white plastic part that it says to use in between the fin and the clamp.The gap is on both sides.why is it like that?

you may not be able to push the m3x8 self-tap screws through the hole w/o twisting but as you screw them in they should go through. either way, i don't see a problem with using a drill bit to make the opening a little bigger.

i think a small gap between the fin and the clamp is ok as long as the clamp holds firmly on the boom.

Thanks for the reply on the fin section.It just seems funny that they would have a gap like that.A spacer would be an ideal way to correct it.

I dont remember having all the problems you speak of, but its been a while and I know I was very frustrated with the bird at first. Most that have built many Hawks are accustomed to some difficulties as with any kit but I found the Hawk to be one of the easy ones to deal with. This does bring up some issues for the first time builder. I still think Century could take some time and make this a Trainer build as it were and make it simple, for it is a good first heli for a lot of folks like myself. Just some simple attention to details. We all take this for granted and all are willing to help in any way we can. First time heli builds are long lasting memories that stick in the mind. MY point is this, Make everything as close to perfect when it comes to (instructions) and the like as possible so the builder feels comfortable to move to the next level. Once he is accustomed to this he will relise some adjustments and tweaking will need to be made. I believe the inadequate instructions and the mixed packaging of the screws cost me alot of time and frustration that would have been better spent learning to fly.

That space is to insure that a newbie does not tighten the clamp to hard and stress the boom.

Im not a fan of the self tapping phillips hardware but the Century helis do fit together nicely the few I have built.
