450 clone build

[Gate88]

Of course it's possible to build a cheap 450 - How well it flies is the question!

Well I buried my old faithful SE V2 a couple of weeks back, there wasn't much left so I set out to get a cheap and nasty replacement in the air.

Ive got me a HK 450 FBL pro for £45 delivered, I've ordered a K-Bar (mini v bar rip off) FBL unit for £22.00 and I'm transplanting my servos, speed controller and RX off the old SE.

So far I'd say the HK thing looks pretty good, the only downside was a fair amount of slop in the tail assembly but I've mixed and matched parts from my old model and got it all nice and snug now.

But having looked it over I can't see why it wouldn't fly pretty well, the proof will be in the pudding and I won't know that til the k-bar arrives but I'll keep you all posted.

I think goodluckbuy have them... Blue version is more expensive than black as it has a led.

From the bay, they've ramped the price up by a quid but if it's any good it's worth the 14 to 40 day wait!

Good idea!
How's the rest of the build coming on now mate? I'm looking forward to seeing you finish it and getting it maidened Takes me back to that thread where I said it is possible to build a cheap 450 heli and most people were saying that it wasn't possible.

Great thread.

Also it's worth balancing your rotor blades, I have noticed there hasn't been a mention of it on here yet, I balanced some carbon fibre blades last night and I couldn't believe how far out of balance they were from each other! Prevents any unwanted vibrations on your rotor head this way

I get the feeling that folks overlook this a lot. The blades may be equal weight but CoG is often well out. That takes a fair bit of sorting out.

I no about balancing but what is CoG

[400blade]

cog = center of gravity

Year I new about center of gravity aswell I will watch the vid soon

[helijohn]

I think a lot of people invest in balancers and when they see the blades balance they leave it at that. I have just checked a pair of blades that have amazed me as they weigh the same, exactly the same, and have a matching CoG. Yet a few weeks back I had a pair of HK blades that were so far out on the CoG I was tempted to sling them out. In fact I don't use a balancer so much these days.

Can anyone help my head is done in

when I conect the battery the heli just beeps all the servos work but it doesn't spool up any ideas

[Gate88]

Have you programmed the ESC?

Motor wires connected properly?

Throttle hold "off"?

[Markmark.123]

How do you programme it I never new ya had to
