Things to check when buying the 130x new before 1st flight and go to forums

[tntburnett]

OK there have been a lot of people having good luck with this lil guy right out of the box and some having trouble right out of the box. So it looks like those who are having good luck out of this lil it was made on Tuesday thru Thursday and for those that is having issues theirs was made on a Friday and Monday (just a lil humor). Treat it like if you would a bigger heli mostly pre assembly heli (trex 450) or RTF ( blade 450) . So here is the list

1. Check feathering shaft for tightness and lock tight also check tail grips
2. Check blades for tightness they are to loose out of the box ( mains and tail)
3. Check gear mesh on A &B gear meaning making sure its not tight against round part of B gear and also pressed against the gear ( boom could be to close in or TT could be install backwards)
4. Make sure the A gear is not touching servo (mosfit) use a piece of paper to check this. if A gear is touching lightly sand A gear.
5. Check TT at C gear make sure the TT is not touching the tail shaft shelve that can cause vibes also if so just cut extra off .
6. Then test fly if you have a wag or bounce change gyro settings here is the forum for this and it is a sticky. https://www.helifreak.com/showthread.php?t=429592

Here are a few forums you could go by and a few mods you can do to make this lil guy your best friend

(If I forgot anything please add to it)

Hope this help everybody out

PS this is not a beginner heli you can't jump from a coaxial or jump on this heli for a beginner heli. start with maybe the msrx so you can at least get the feel of fbl and movement and orientations then move your way up.

Be blessed
Isaac

What about violent head shake? I maidened mine earlier today, and apart from intermittent head shakes it flew great. Everything on the head seems tight.

Install better o-rings or use grommets in the head assembly.

As above poster said, add the canopy grommets (extras included) to the swash because the o-rings are too small. I had VIOLENT head shakes on my heli, they went away with this mod!

Sorry about sounding like such a newb here, but where are you finding a listing of what is A,B,C gears? Also, what is TT?

[tntburnett]

A gear is the blk gear B gear is the lil metal gear being drove by the blk gear C gear is at the end of TT shaft near the tail case and D gear is the gear on the tail shaft.

Starting at the closest gear that is powered from the main motor, just trace it back. Big crown gear on the main shaft is the "A" gear, little metal gear is "B" and so on. TT stands for torque tube, which is the rod that runs through the boom to supply power to the tail rotor.

TNT it might help a few people if you add this to your list.

Someone on this forum mentioned the screws for the main shaft were very short and only held one side of the main shaft, I found this to be true on my 130x.

The hardware kit [blh3122] for a 120 sr has longer screws of the same pitch, they are long enough to engage both sides of the shaft but not so long that the would stick out.

Just thought I would put it out there in case anyone wanted longer screws for their main shaft

P.S the longer screws also work good for stripped frame holes, they will grab further into the hole than the shorter OEM screws.

Hmmm, thanks for the tip. Since I have a 120 SR and the hardware kit, I am going to do it. Also, Isaac, I am going to give your idea a shot also. I feel that all the mods I have tried so far from suggestions of different folks have really contributed to my heli being so smooth and stable in flight. When I first checked my helis out of the box and rotated the main blades, I new something was wrong because it did not feel smooth. One thing was the A gear was slightly rubbing on the FET and by using a suggestion from someone on HF, I sanded it down with 320 wet&dry sandpaper and that help a lot plus other mods.

Keep up all the good work guys. Love this forum and hopefully everyone will eventually get there's flying well.

Yep, this worked perfectly! Thanks for the tip!

Now I just need to work on collective management. It's easy to bog this thing, and bogs can be deadly (the 130x falls right out of the sky).
