Default Blade 450x

So far I am really enjoying the 450x. I had to trim the tail a bit with the transmitter to get it from pirouetting, so I'll manually adjust to get it straight. The main shaft seems to be off center, but I flew anyway. This resulted in stripping the main gear. Also it seems as though a servo is stripped as well, and the heli did not crash. Guess the servos aren't too good. Are there any hk servos that would work better?

Sounds like a newbie awareness learning curve.......

It really does not matter what manufacture you purchase from, every model really needs to be gone over mechanically, "with a fine tooth comb" before any type of airborne activity commences.

Main shaft, main gear, servo, linkage issues can be identified almost immediately with a thorough powerd-up bench test first...there are a dozen safe ways to perform this with nothing more than average shop equipment.

Blade's are generally equiped with E-Flite electronic equipment, ie., servos, RX, gyro, ect....... and most of the hardware is semi-exclusive.....a very good thing is that parts are pretty available for almost all Blade heli and multi-rotor craft........E-flite has been around a very long time, most of the aftermarket stuff is really no better than E-Flite., unless one ventures into the higher end CNC rotor/tail heads, Hitech servos and very expensive gyro's...based on experience.

Oh I knew the shaft wasn't straight. I just didn't want to leave it on the ground because of it...I should have though. I checked all parts prior to take it out for first flight. As for the servo, it was fine when spooling it up. In flight it was find too, it wasn't until after landing after second flight (when gear gave up) that I heard the servo. So it wouldn't be better getting some metal gear servos from hk or something?

The orange module is working fine. No crashes whatsoever, took it up, did a couple flights back and forth and took it down.

Build Review

I've never used HK or any "off" brand equipment that was not OEM or otherwise considered (proven) better than OEM on any of my 450's......As far as MG over nylon, ibme that unless you really need the torgue aspect of metal gears, nylon are far more forgiving on the connecting linkage gear, less expensive to replace and reliable enough to learn with........just stay with digital (especially for the tail rotor). Servo's are like eveything else in this hobby, you get what you pay for.....thus, stick with an industry proven name brand and stay with the stock size and configuration.....otherwise, your'e likey just to increase frustration and replacement.....especially due to the "knocks" your 450 is experiencing.....

Fair enough, just got a bad servo it seems. At least they don't cost you an arm and a leg. Even the gear and shaft isn't too costly. I'm really liking this heli though, stable, predictable. Was not even scared to fly it, just felt in control the whole time, unlike the mcpx BL. Having not crashed it at all speaks for itself. Once I get better ill move to the mcpx BL to try inverted, and then go back to the 450.

Not sure if they changed the servo mounts on the Blade 450x but on the Blade 400 the HXT900's fit fine after some filing.

Any equivalent HXT900 servo's would work. A word of caution some of the other off brand servos don't have very good centering which is actually pretty important for an RC heli. The HXT's have always proven to be pretty good in this respect I'm not exactly sure what people consider the equivalent metal servo to the legendary HXT900 but if the dimensions are similar I would go with that.

The Blade 400 had pretty crap DS75 servos that were eflite branded and the HXT900 out perform them in static holding force, amount torque available, and also centering so yeah they are cheaper but it doesn't mean they are inferior.

Im interested in this heli as I have heard great things about it. I have mastered 4 channel flight and am afraid I'm not 100% ready for full on 6 channel collective pitch. Has anyone converted these into a FP heli, and or can the settings be dialed down so it resembles flight similar to a FP heli?

LOL.....your kidding right.....

To answer the question........Yes, there have been conversions done on Collect Pitch craft........The RCG forum has a couple of interesting mod's.....a few years old.

Quite frankly, it's a complete waste of time.....!

The Blade you are looking at is really not for a newbee.....ya, parts are available and inexpensive, but by the time you've actually learned any thing........you'll be a better mechanic than a pilot.

Start off with a smaller E-Flite Macro............the newer ones come with SAFE and AS3X.......you'll have more fun and less frustration.....which translates to positive learning........

Start off with a 130x. It is the most finicky of the small helis but there a few reasons why I feel it is the best (it has been my learning heli). Firstly, it is a lot more stable and not as jumpy as helis like the MCPX BL (which is the worst beginner CP as the power is insane) and the Nano. Secondly, it is a true one motor heli, giving better response than the MCPX or Nano tail motor. Thirdly, while parts are a little weaker than the Nano or MCPX, it is actually stronger in a couple areas: the landing gear (the MCPX and Nano have skids that hold the battery and, in fact, break on the slightest crash), the board (the 130x has the board on the bottom of the heli, above the skids, and is wrapped in plastic with a little bit of foam in it, while the MCPX and Nano have a board held on by two screws in the front...to say the least, one bad hit on the Nano or MCPX and you are $50 or $100 bucks, while the 130x board is in a better location). Overall, the 130x is actually cheaper than the MCPX BL, isn't as overpowered, is more stable, and the worst parts to break on the helis smaller than the 130x are actually not an issue at all on the 130x.

I would advise going against the 450x. I do like mine, but it isn't cheap to crash. One crash and it is almost guaranteed that the blades are toast, the boom is likely bent, the canopy is no more, and areas in the head are a good 75% of being damaged (this decreases once you learn throttle cut, but the blades will always be badly damaged). I recently had a malfunction of the AR7200BX, where in a hover the 450x suddenly went full pitch...in the car wash at work. It shattered many parts, including a brand new set of blades, the main shaft, boom. I don't know what happened, clearly something didn't engage properly when I turned the heli on, but if this was the 130x, it is likely no damaged would have happened. The 450x is also intimidating (it makes your lawnmower look like a cow gnawing on grass), very high powered, and not cheap in any respect.

As for turning a heli into collective pitch, this will make flying harder, and could likely damage the heli. First off, changing pitch is much more accurate and quick than changing rotor rpm. Second, I know that the smaller helis like the 130x, the boards will heat up more and cause damage to components if this heat isn't controlled (anything below about 80-85% power I have read). On the 450x, I am not sure if lower headspeed or constantly changing headspeed causes damage to the system ( likely not) but the 450x, along with other helis, actually lose stability in a simple hover. People do lower head speed and fly for 10 minutes vs 5 minutes, but flight is visibly sluggish, response is not at all crisp...think of Big Ben flying around London with a rotor above it.

I feel there is no way to learn CP, other than going for CP, even if in a sim to start. No other heli or quad truly teaches you. Even from a basic hover, the feeling of a FP to CP heli is night and day. I still have a long journey and I find myself going to the 130x every time, which has, I admit, a few issues, such as the gears, a servo, but nothing as expensive as the parts in the 450x or the boards of the Nano or MCPx. No matter the heli, the simple fact is is that they are all finicky, and not durable like planes are. If you want to get into real rc helis, you'll see flies in you wallet, but it is very fun and a lot more challenging than most planes.


One last thing, dialing the CP heli down. This can be done, but not too low, as no matter how low your settings (even if you put aileron, elevator and rudder down to 5% travel), the heli will still drift where it wants to go, as this is natural. I have learnt to keep everything at 100%, other than rudder, and 0% expo and learn to move the sticks millimeter by millimter. This is important I feel, as because a CP heli drifts, especially smaller ones, you need constant stick movement, and the less you have to move from center stick for most flight patterns, the quicker you can be. If you add expo and lower throws, you suddenly find yourself moving the sticks a lot more, ending in slower response and overcompensating. The best way to get a heli to be tame is to get one designed to be not as high of a headspeed (Nano is an example, although I hate that dang board), or the 130x (slower than the 450x, 300CFX, MCPX BL, or the upcoming 180CFX). This causes a heli to not hop around as much and is more gentle on the throttle control. Weighted bullet blades (standard on the smaller Blade helis) also help. Lowering throws on a 450x can be done to a certain extent, but it isn't a heli form of a Cub to begin with. Lowering headspeed isn't the best option either, as a particular heli is designed to fly with a certain headspeed. If you really have to tame things, do a combination of throws and headspeed, where you won't mess up the gyros, and the lower headspeed will slow drifting so that your lowered throw range can still work effectively.
