Stuff you need
You really need a Scorpion 2208-4660 A LYNX frame brace and an Align complete pro or sport 450 tail grip set with the hub it is about 19 bucks. But until you get these items make sure your motor has plenty of gear lash or it will kill your motor fast. come check out our 300X facebook page there is loads of tried and proven information there. http://www.facebook.com/groups/417925564936759/

Just my opinion but for good sport/med 3D the 300x fly's very well stock.

Besides checking/adjusting the ar7200bx settings and your +/- collective pitch (should be ~+/-12 deg) there is not much to add. This is a heli aimed at intermediate/advanced heli guys so I assume you already know how to do all this basic setup stuff.

One thing I recommend you do is slid in a few thin strips of plastic (like the plastic packaging on may rc bits) between the rear servos/frames. This mod really stiffens up the 300x frameset and help stop the mainshaft from rocking back and forth (one of the main potential causes of mainshaft failure).

The other important thing to do is to make sure the 300x is as vib-free as possible.

Check this initially by running up the heli with no main or tail blades. It should run nice and smooth. If it does not, track down the source. Could be a motor, maingear (or it's poor installation on the hub), poor gear meshing, too tight belt tension, or a bent mainshaft and/or tail shaft, for example.

Next, add the tail blades and with them ~ centered run the heli up holding it in your hand, or tie it down if necessary. If you get some transitional vibs dynamically balance the tail blades by adding a bit of tape (~1" of electrical tape) to the mid leading edge of one blade and run it up. If it is worse, take the tape off and add another piece to the other blade. If necessary, adjust the amount of tape, trial/error, until it's smooth and vib-free.

Then, add your nicely balanced stock woodie main blades (make sure they are nicely balanced btw!), run it upa and track them if necessary, and go fly and enjoy your vib-free, great flying 300x!

Later, if you want a bit better performance, add a set of good quality CF main blades. I like the Blade CF blades @ ~$30. They are nice and stiff, very robust, and do not need any spacers/shims. Go through the Bx setup and increase the collective pitch to ~ +/-13.5 deg. The heli will really start to come alive and you can then do some pretty hard 3D with it.

Like all heli's, there is no limit on the amount of things you can upgrade. Personally I try to avoid as much 'Bling' as possible but even I get caught up buying nice shiney bits once in a while, lol! For the 300x, I recommend you try to keep this bling to a minimum. If you want to do any significant performance upgrades you are far better off just getting a better stock performing heli like the 450x imho.

Anyway, just my $0.02 worth. Hope you enjoy your 300x. I love mine!

Cheers,
TomC

I just got a 300X last week, haven't been abe to fly it yet. Too cold (been below 20 F) and windy. Been reading up on the 300X threads though.

Have a question about the plastic shims TomC. I am not familiar with rc bits so about how thick is the plastic you are using for shims?

Thanks,
Keith

Hi,

something like a piece of mylar hing tape might do the trick for this, it just needs to fill the gap between the servos.

However if you can get the frame mode this shouldn't be needed.

Asteroid designs and Lynx both do one for the 300.

The Asteroids one neesds to be glued to the frame,

the Lynx one bolts onto the frame....

Ya, any thin bits of thin plastic sheet will do. Even maybe bits of you wife's credit card cut up, lol! Just need to wedge enough in between the rear servos and the frame to tighten things up back there. You will really notice the diff before/after if you try rocking the head a bit.

I do not think that any of the aftermarket frame stiffeners are really necessary but if you use them you should still do this 'shim mod' imho.

Cheers,
TomC

and she just got a new one yesterday

Thanks.I will try that or a few other ideas I have if that is too thick. I am trying to keep this as stock as possible. Got it to cheaply try new maneuvers, but no hard core 3D.

Thanks for the input from each of you. I havent been able to fly it yet either due to being out of town for work. But when i get back, its game on. I got a heck of a deal on it for doing like kcgraves, trying new moves but in the yard. TomC, thanks for the info, ill give those things a try. It came with cf blades and a few bling items, heck, the guy never flew it. I am familiar with bx so adjustments wont be a problem. Ill give some feedback when i get home and get some decent weather.

fwiw...
+1 on TomCs' post...When I got my 300, it flew well out of the box, not unlike my 450x....After a few flights, I had an unusual tipover on takeoff..Started looking at heli, began reading about vibe issues..While mine had never displayed any visible signs of vibration, and the blades had been balanced as usual, I was not expecting what I saw when I spooled up as described with just t/r blades..Massive vibration of t/r box, but fin did not display much vibration at all...?
Bottom line..Dynamically balance both rotors as described...Makes an incredible difference..Went from good to exceptional.

John.

Just got a 300x and have about 5 flights on it so far I really like it. As mentioned it's not overpowered but I'd say I'm happy with the power level.

My question pertains to shimming the rear servo frame. Mine is quite tight back of the servos and doesn't seem to need modification of any kind - even when I gently force the mainshaft around.

What's up?

Wedge thin pieces of plastic between the servos, top, middle, bottom and this should stiffen the frames quite a bit. No need to shim front or back of the servo mounts like is sounds like you are trying to do?

cheers,

I see what you're talking about now, Tom. I'm still not seeing a reason for it though. My frame seems quite flex free. More so fore/aft than side to side but either way very good IMO.

This heli is so light that I don't envision (or notice inflight) any lack of response that might be due to frame flex issues.

Matter of fact, it's plenty responsive (with HH carbons).
