Is this the version with a flybar? If so you need to fix the flybar in position before measuring blade pitch. Tony has a great video on setting up a flybar head. I'm not very familiar with the Blade 450 but on other models it's quite common for the tail boom to rotate in the tail boom mount...

Extending the motor wires isnt usually a problem but I've seen a few Trex 700X builds on other forums and those guys didnt need to do it. They all seem to have orientated the ESC with the motor wires to the rear.

You shouldnt use a battery and a BEC unless you use some form of device to isolate between the two (a suitably rated Diode will do it but you can get propitiatory gizmos like the Optipower Ultraguard). Personally I just keep to simple and use the BEC on it's own. No, the HW doesnt have...

The 700X doesnt need a LiPo for the Rx because it uses one of the new Align (rebadged Hobbywing V4) ESCs with a built in BEC.

Phil, On the subject of flight times in cold conditions. You should get virtually the same flight time but what you do get is lower voltage during flight. If you are using battery voltage monitoring for controlling flight time the low voltage alarm will 'go off' a lot earlier, but that doesn't...

Planes were my first love in RC, I was flying planes on and off for over 35 years before the heli bug bit. I still fly the planes now and again and I'm still interested in seeing build threads etc. One of these days I'll take on a balsa scratch build again but lately i've been too lazy so it's...

I'm away on vacation for a couple of weeks but will take some photos when I get back home. Suffice to say that having both batteries point forward isn't a problem.

Good work Tony. Stay strong quitting is a great move.

If you broke the blades and bent the main shaft the it's very likely that the feathering shaft is also bent. A bent feathering shaft will make the bearings feel tight. To check the feathering shaft remove one blade, put an allen key into the screw head and rotate the feathering shaft. If the...

Bear in mind the AS3X gyro system doesnt stabilise the plane like some other systems do (such as Horizon's 'SAFE').. All the AS3X really does is make the plane fly smoother and make it more resistant to wind disturbance, both of which are good to have an a ultra micro plane. AS3X doesnt do any...

A FBL with 'self leveling' stabilisation like you have with your Spirit pro would make a big difference for him. The Spirit even has 'co-axial' mode that makes a CP heli fly like a co-axial (i.e. so easy your granny could fly it)

That's a lot of parts you have there!.. Must have been close to a 're-kit'? She looks great.

Yes, the ESC should stay bound until the next time you put it into bind mode by inserting the bind plug. If your steering servo isn't responding (but throttle is) the likely reasons: Servo plug is inserted in reverse orientation into Rx Servo plugged into wrong channel on Rx Faulty Servo

On the 700 size, 5mm bullets. The Supra X bullets are better because they have a plastic shroud to protect from shorts where plain bullets like I'm using are quite vulnerable to shorts if you get careless for a moment.

It's the wire length that i was referring to. I use series connections on several helis, including four helis with tandem mounted batteries similar to your 700X, and have never needed to extend the wires. You wouldn't normally mount the batteries as you indicate in the diagram. Normally you...

Phil, It's a conflict between the rational side of my brain which tells me I have already got too many helis so I don't need another, and the emotional side that tells me I want a new one regardless! As for the connectors... On the series setup for the 700X you shouldn't need any extensions...

Seems like everyone is getting new helis which doesn't help me fight off the urge to buy another heli that I don't really need! A guy on one of the UK forums is actually selling a Trex 700X which he has built but only flown a few times, the heli cant be more than a few weeks old because they...

Tony, the headspeed looked low at the time you got the tail kick, which would explain it. Was it flying in 'normal mode' by any chance? Otherwise it looks pretty good, just a bit of rust to work out of the fingers maybe?

No, what i meant is that DC negative is connected to ground internally inside the PSU. You should be a able to prove that with a multimeter checking for resistance between DC negative and the case. This is normal for any PSU but it's a serious problem if you have them connected in series...
