What motor is best? I have tried the amo motor they recomend on the box. It was all right I guess but I was Learning then and did not realy get in to 3d. After that I tried the align 430L. It had a lot more rpm than the amo but less power. What should I go with next?[sm=72_72.gif]

RE: MX450 XS Discussion Thread
 

Oh, that's a loaded question that will get lots of opinons :). My MX has a JGF 500TH set up for 4S batteries. It provides as much power as the helicopter can handle.

RE: MX450 XS Discussion Thread
 

Who is JGF and where can I buy one? can it be run on 3 cell??????[sm=confused.gif]

RE: MX450 XS Discussion Thread
 

JGF is JustGoFly, www.justgofly.com, or Helidirect also carries some of their motors. The Scorpion HK 2221-08 is also worth a consideration- it uses more juice, but it's that tad bit more powerful, too. I don't have one in the MX, but I do have one in a MiniTitan and it cooks :D. Got that one from neoplanes.com.

[edit] Oh, and yes, the JGF works great on 3S, I just like lots of power. Odd company name, but they have good products and the guy that owns it is a RC guy, too :). [/edit]

RE: MX450 XS Discussion Thread
 

;)Hi guys,

Is the MX450 XS discontinued? I looked at the "Tower Hobbies" sight and it shows it discontinued.... Any other sights that might have the HeliMax MX 450 XS in stock? The Heli-Max sight does not show the Helicopter out of production, what gives? thanks

RE: MX450 XS Discussion Thread
 

You can buy the ARK 450 from the manufacturer (http://www.arktaiwan.com.tw/), but Tower and GrandRC were the only U.S. places that I knew of, and GrandRC's price was pretty high anyway. HeliMax rebranded the ARK X450-XS as the MX450; since ARK isn't going anywhere, and the MX leaving gives HeliMax nothing in the 4x0 size, there's a lot of conjecture about what comes next.

RE: MX450 XS Discussion Thread
 

I ordered one and a week later they say it is discontinued.........


I will fly it as long as I can get parts for it. Mine is almost ready to fly. I am just waiting for the JB weld to cure on the tail rotor link. I went with a boom mount for the servo so I needed to shorten the link. I tried to solder it but none of the three type of solder will stick. I will replace most of the metal push rod with corbon tube next week. I have three days and the hobby shop is 50 miles each way.

I will pick up some servo to replace the HS-55 next week too.

RE: MX450 XS Discussion Thread
 

I made carbon pushrods for my MX' usually. Be careful that you keep the links in good order if you don't use guides, though- if they come off the pushrod can get into the blades.

Parts for the MX shouldn't be a problem for a while, and even if they start to dry up, there are any number of subassemblies (head, tail, frames, so forth) that people customize with - by the time you can't fix it you'll probably have moved on to something else.

RE: MX450 XS Discussion Thread
 

I have read this fourm from the beginning. It is sad to see somone forget where thy came from. I also have T-REX Nitro PRO. I still have't fogot my 450xs. I would never discurage anyone from any heilcopter. It is about the sport, not the money or skill. With that being said. There are over 100 web sites that still seel the 450xs, so I don't think you have to worry about parts and upgrades. The MX 400 Pro Has been Discontinued. If Tower doesn't sell it it, it is unavailable. With the resent bad mouthing of the 450, form somone who forgot were they started from, it is still a really good heli that performs very well and is crazy with upgrades. All helis need upgreats. Just remember, as your skill improves, so will the qaulity and size of your helicopter. The 450xs is still a 30 size or mico heil. Keep that in mind. For those of us who still fly and learn with the 450xs. Hopfully we don't forget where we started and that we are not super arobatic pilots. The 450xs is just what we expected and more. We read and learn from this foum to better our skills an knolage. Hopfully to make us better pilots. If this is not your favorite heli any more. Please keep your comments about the 450sx to your self.

RE: MX450 XS Discussion Thread
 

I have a question concerning pitch angles. I have seen all the suggested pitch curves that have been suggested on here and I am curious as to what the angles, in degrees, you guys are getting. Can anyone please give me thier pitch angles?


Thanks,
David

RE: MX450 XS Discussion Thread
 

+/- 9 or 10 degrees is good for the 450. You can run it as high as 12, but at a lower head speed it takes a lot of power to drive that, and at a higher speed you don't need it.

RE: MX450 XS Discussion Thread
 

hey guys,
is jr flight pack servo good

RE: MX450 XS Discussion Thread
 

Top shelf yes its good.

RE: MX450 XS Discussion Thread
 

I had something very unexpected happen over the weekend. I was tracking the stock blades on my 450 when I heard a pop and fiberglass flew everywhere. The heli then flipped over and proceeded to bend the flybar shaft, feathering spindle, break the canopy mounts, and the landing gear, and strip the gears in one of the servos. While vacuuming up all the fiberglass out of my carpet, I found a big chunk of lead in the floor. Come to find out, that loud pop I heard was one of the blades slinging a lead weight out it. Contacted Heli Max and they told me there was nothing they could do about the situation. [:@] Now I have to order about a hundred dollars worth of parts from Tower.

Has anyone else ever had or seen this happen before?

RE: MX450 XS Discussion Thread
 

Helimax CF blades are some of the worst blades, sorry to say.

Unfortunately that is how Helimax deals with their customers too.

Sorry to here about the crash.

RE: MX450 XS Discussion Thread
 

I've always gotten excellent service from Tower and Hobbico. They sent me two new sets of CF blades when my first ones were bad, but the new ones weren't any better, unfortunately. Others I know have had long parts list or entire helis replaced. Customer service, good; manufacturing, inconsistent :D. But dpleasants, it's pretty normal that the vendors will say you're on your own when it comes to crash damage. Still stinks, sorry.

RE: MX450 XS Discussion Thread
 

That is just it, I DID NOT crash. My heli has never flown. I was tracking the blades when one of them threw a big chunk of lead out.

RE: MX450 XS Discussion Thread
 

Understand- misstated, I guess. I should have said something like "physical damage" to be clearer. It seems that mfrs feel that if the heli is in little pieces they don't know if you wrecked it or not. You can sometimes persuade them by being assertive, but it doesn't always work.

RE: MX450 XS Discussion Thread
 

lol. Oh well. What blades would you guys recommend? I am thinking about a set of wood blades until I can get this thing off the ground and get better at flying it, then maybe go all carbon fiber.

RE: MX450 XS Discussion Thread
 

The Align blades are ok, wood or FG, and you don't worry about breaking them because they're cheap. I wouldn't choose them for aggressive flying, but they're fine right-side-up.

RE: MX450 XS Discussion Thread
 

My LHS has a set of wood E-Flite 325mm blades. Anyone had any dealings with those? Where do you buy Align blades?

RE: MX450 XS Discussion Thread
 

The Align blades work just fine for aggresive flying. The Pro325 woodies are limited to about 2800 rpm. The new CF (white blades are great). I also like the Hyperion 325. I have seen several makes of blades shed the lead weights. The Trex 600 blades where recalled for that reason. This is the reason you never, never fly a nicked, damaged or suspect blade. The stock blades are good for mixing paint and so forth. Tower has been great to me when taking care of a problem and have never told me that I am on my own, not on over 35 years dealing with them. But that's what you get when dealing with off shore houses. word of advise is to never say you crashed anything. I would be suspicious also if I was a dealer. Sorry to say that there are a lot of GOOBERS who are not as truthful as you and I.

Jim

RE: MX450 XS Discussion Thread
 

Thanks for the info Jim. I am running about 2490 rpm for the head speed. On a side note, has anyone checked out swanghobby.com? They have some awesome prices.

RE: MX450 XS Discussion Thread
 

I was talking about the woodies and FGs; never tried the carbons. The woodies are too draggy compared to the SAB and CY Radix blades I usually use, and in my opinion the FGs are too flexy in maneuvering.

RE: MX450 XS Discussion Thread
 

I agree with you buddy. The Radix are super blades and will let you auto the MX450. I have not tried SAB lately. The Hyperion blades are very thin and stiff and I perfer them so far over anything I have used. The Align 325 Pro woodies are great for beginners and @ $12 a pair are a good value. I use them myself from time to time when I trash my good-uns. Just watch your headspeed at 0 pitch and CA the plastic to the blade. The Hyperion are about $38 vs $45-$49 for the Radix and V-blades. As far as FG and plastic blades cut them off to about 5" each and use them for head set up and use the end you cut off to mix paint. I never use bargin basement blades. Buy only know good products and don't wast your money. I feel they are dangerous. As a note you can call the Radix folks and request a set of blemished blades for about 1/2 price. Nothing wrong with them other than decortive items.
