I've made this video to show how I've set up my E-Razor with the stock radio. Hope it helps anyone out there.

Don't have a heli? The E-Razor 450 is a great 3D starter heli, it is anything BUT easy to get set up and working, but once you do, it's a tough bird and will do what you tell it. Parts are also cheap.

Great starter video for us beginners. I have this heli. I haven't tried flying it for about a year and got it out the other day. The heli went full throttle as soon as the gyro connected with the transmitter so I turned the transmitter off to avoid crashing. Now I can get the heli and radio to connect at all. Any sugguestions? What did I do? Thanks!

@WVrocksWV

Another thing before you connect, disconnect 1 of your 3 motor leads, that'll keep the heli from spinning up full throttle while you test it out.

Now turn on your tx first(ALWAYS!), and then plug in your rx(heli's esc, since it has a bec on it). It should connect and your gyro light should go blue(make sure you have head hold mode on). Your servos should become responsive to your sticks.

If it still wont' connect, your antenna wire might be broken in your rx or tx.

@WVrocksWV

You can check your rx/tx antenna by opening up the rx and tx and making sure there's conductivity to the tip, just strip it a bit and use an ohm meter to check from the solder point to the tip.

It sounds like you started up in idle up mode.

Make sure your top left switch is up for HEAD HOLD mode, and your top right switch is down for NORMAL MODE operation(Variable throttle), instead of IDLE UP(That means full throttle).

I asked you to unplug 1 wire. The motor will twitch instead.

@WVrocksWV

Hope that helps, give that a try and let us know how it goes.

The motor should only twitch if it tries to throttle up now, it won't be able to spin very much if at all with only 2 wires connected. It's safe.

Cheers,

David.

@DavidSunshine867 Well, I gave these options a try and still no response from the heli--just red/blue on the gyro. It worked several months ago and randomly spooled up out of control the other day before I shut it down. Could something have suddenly failed by chance? I'll walk through each of your recommendations again just to double-check....Thanks for your help!

@WVrocksWV

Strange.

Do you have the 2.4ghz radio?

[WVrocksWV]

@DavidSunshine867 No, it's the 72 Mhz above. When I turned it on the other day it connected as usual but I guess some of the switches were incorrectly set so it throttled up right away so I simply turned the radio back off. I checked the proper switch settings on-line and went back and now it won't connect. It's got me puzzled as well but I am new at this. I just want to learn how to fly it.

[DavidSunshine867]

@WVrocksWV

Thanks!

I might be able to help. 

First, make sure you have charged/new batteries in your transmitter (tx) and receiver (rx)/heli.

Then take out both crystals(in the rx and tx) and inspect the contacts, if you don't see anything, install and remove them about 10 times just to make sure the contacts are clean, it could be a loose connection. If you see crud, clean it with a pink eraser.

Before trying to connect, make sure your idle up is down, and throttle stick is down.

Thanks for noticing and commenting!

If you're looking for a beginner heli, this is it. If you're looking at more of an extreme 3D capable beginner heli, then you'll want to get a CopterX 450 Pro or better. Check out the RTF CopterX kits at ehirobo, they're not bad, pretty good quality for your money.

This heli is good for those who want to stay with sport 3D(That means just loops and flips, nothing crazy like tick tocks and backwards funnels).

In the 2 months I've been watching videos about helis while trying to make a decision, this is the first one that really shows the movements up close for the swash plate & blade pitch the slow/fast movements with the TX sticks.
