Hi,

New pet peeve of the day...

The random three digit number naming convention for helicopters.

The number may or may not have anything to do with the blade size, weight, engine size, etc. Bigger numbers for a given heli company seem to be bigger helicopters. But one company's 500 is bigger than another company's 500.

It has people asking "is that a 600 size?" And I get to answer...

"It's called a Blade 400"
"Nope, its a 325 mm blade size."
"Nope, this 400 is the same size as a Trex 450."
"I don't know why."
"Nope, I don't know. I just bought it and I fly it."

It creates a great deal of questions that I don't feel responsible for answering, and those who are responsible (manufacturers) aren't at the field to take the puzzled look off of the new guy's face.

Consider the following I just googled:

Trex 250 = 205mm blades
Blade 400 = 325mm blades
Trex 450 = 325mm blades
Rave 450 = 350mm blades
Trex 500 = 425mm blades
Logo 500 = 500/520mm blades (at least they got this one right)
Trex 600 = 600mm blades (hey another one, keep it coming!)

See my point? The current naming of helicopters is really confusing. Has nothing to do with the engine. Has nothing to do with the rotor size. And they aren't even categorized across the board. Your 500 is bigger than another guy's 500.

Used to be we had the Raptor 30. A sceadu 30. A raptor 50. A Raptor 60. A Raptor 90. A Fury 60. An Evo 90. A Fury 90. See my point? At least SOMETHING on the heli was 60 or 90, etc.

I think the electrics have a lot to do with this. But then why not go on blade size, or Volts or something. Heck even tail boom length I don't care. But not a random number.

So someone asking "is that a 600 size" is speaking gibberish. I sort of get what he's asking but not really. Really there is no "600 size." Pretty soon I guess we'll see the SUX 2000.

OK rant over. Bring on the flames.

I agree, it is a dumb way of doing things, I think it should be directly related to blade size.

Electric helis are roughly named by electric motor size.

Nitro helis are roughly named by glow motror size.

BMW's are named by motor size (in liters).

Lexus is named by motor size (in liters).

Yeah it's that "roughly rated" thing that gets to me.

The nitro naming convention is MUCH less rough than the E stuff.

Your answer just begs more questions.

Here's a few examples. I wouldn't know where to begin as to which helis each of these belong in...

TTR2380 BL Motor OBL 49/08-50H
Say again?

KX850165TA 430XL Brushless Motor (3700kv)
The 430XL, what does that mean? That it fits the TREX 450? OK but you missed it by 20 there, Align! Maybe the XL makes up for the lost 20 points.

A50-14S 10 pole Hacker Brushless Motor
Turns out it's for 5-7 lbs. And would absolutely smoke that 430XL. Who'd have known?

Again, the aircraft following the naming convention of the motors makes no sense. The motors themselves are just hodge podge classifications.

To be honest, who cares. Naming conventions are one of the easier items you will learn if you get into this hobby.

At the end of the day, I don't care. I have (more than) all the helis I need. I don't need to learn or keep up with any products. If I'm confused about all this it doesn't hurt me one bit.

But when someone starts asking me questions about it, I'm probably going to send them packing. "Sorry dude, I don't have a clue if a Superglide 700 is the same size as a TRex 700. Do a Search. If you can make sense of it let me know. This subject just annoys me. Stand back I'm starting my engine..."

See how it can backfire marketing-wise?

Wouldn't this sound better? "Yes that's a Trex 425mm, you put 425mm blades on it. It's more expensive but its bigger and more stable than the Trex 325mm. You could try the Logo 500mm for even more stability. Or step up to a Trex 600mm." "Thanks man!" "No problem. My pleasure. Now if you'll kindly step back a second I'm going to start this engine and go fly."

They should rate it by the body part you have to sacrifice to get it:

T-rex 250 = Big toe
T-rex 450 = Both Big Toes and a pinky toe
T-rex 500 = All toes or one foot, your choice
T-rex 600 = A kidney, or both feet. Your choice.
Vibe 50 = A kidney and part of your liver.
Synergy N9 = Any part of your genetalia. Your choice.
Turbine heli = Both feet, all genetalia, and a kidney.

When I started in the hobby, I always thought 300-400-500-600 were blade size in 'mm'.

Also rating for brush less motors are is very confusing too.. It should be Diameter and Kv. When you go shop for motor its like can we just sort them by Diameter of it?

I agree w/ Taz. Not meaning to hijack the thread, but I nominate the Blade mCX as there most terrifying heli currently out there. Take two Xanax before operating.
