Just got my sdx kit and was wondering if there was anything I should know about before I start building? Any problem areas that any of you have noticed?

the build will go smooth. the one thing you might need (depending on what servos you use) is a set of servo spacers. You can make them up your self of you can buy a set for a dollar two. They should be placed behind the CCPM servo nearest the main mast. Other then that you are good to go.

I didn't need the spacer for my bird.

Another thing that is a must is tap the holes in the swash plate where the balls thread in. That has been a problem unless the factory correct it.

Most that have built the bird filed flat spots on the fly bar where the set screws sit. This makes it easier to get apart later.

Also I think the stock head setup is a little too mild. I think most guys move the ball in 1 one on the mixing arms.

The flybar paddles give you options for weight. I think just the brass or no weight has been popular.

Good luck. You will find lots of help here if you need it.

Thanks, TheWoodCrafter

I just finished my SDX. Actually I did the maiden today.
I asked a lot of question recently regarding this here in the Hirobo section. Among others I want to point out these tip:
-tap the holes in the outer swash ring with a proper tapping tool. Otherwise it might crack.
-balance the fan/hub assembly (mine was really out of balance).
-file the flat spots in the flybar. (I did not, but might regret the day I need to replace it).

But the build really went smooth. I had a really nice time doing it.

Servo shim plates from Mavrikk and Heli Proz or your LHS should have them.

Well I started building tonight and got to the point where i needed grease and had to stop because I don't have any at home. I will get some in the am. It should resemble a heli tomorrow.

do not forget to use epoxy or other glue when you attach the RC tray to the frame (the inserts that the screws go into).
Also use epoxy on the flybar carrier.
Finally, fill up the tail rod tube with WD40.

It is a great model!

Just updating my progress. The frame and head are all together now. Tomorrow it goes into the tail section. After that I think I will be at a standstill because I still need the engine and electronics. Unfortunately I have other things going on right now that are a priority so this project is going to take a bit to get finished. I may not even put a governor on the heli until later on so this bird is going in the air in basic fashion.

For break in period you don't need a governor. It's not a necessity but it's worth having one.

Today the tail section and boom went on and it now looks like a helicopter. Unfortunately I have reached the point where I cant go any further with it. I need to purchase an engine and electronics to proceed. Its been fun so far and very therapeutic.

Hey Vinnie,

Now is the time to do the canopy.

Thanks, TheWoodCrafter

I use CALLIE Graphics on my Hirobo Canopys
easier than paint and doesn't flake or
chip off. Many color and design options.

Give Callie a call

The paint is rattle can paint called LusterKote by Top Flite.
It is fuel proof. Bought it at a local hobby shop. The kid behind the counter didn't know what "fuel Proof" was. I guess they are used to selling that dull paint for the inside of R/C car bodies.

After I added the sticker I clear coated it with some automotive 2 part clear to seal things. I guess you could skip the clear coat.
That stuff is expensive and you need spray equipment.

Thanks, TheWoodCrafter

One thing that you need to do before you fly it is to pull the pins out of the washout and dremel a little flatspot on the section that just fits in the block and CA the pins back in. There have been instances where the pins will drop in the block and this is the fix.

Vinnie, good luck with the rest of the build. It is a fun model to build and even more fun to fly it!. I built mine last summer and it has been an awsome heli to play around with. It has been one the most dependable helis I have ever owned.

Nice paint job by the way. Has the paint been holding up good for you?. Did you have to scuff up the plastic at all to get the paint to stick and or did you have to primer the canopy first? The important thing is that you sprayed it with an automotive clear coat. I have used the 2 part automotive clear coat on my MA Fury helis in the past and it holds up great. But like you said, it is expensive though.

This is the second one I have done.

The first one peeled. This one is holding up very well.

I learned to sand it and wash it with soap first.

No primer, just paint.
