Goint to put power into my new Trex today...

[Cralis]

Right, my batteries which Mike at Aurorra modified to work with the CellPro, as well as my ESC with the Deans connector added, arrives at my house today. So I'll be heading home a couple of hours early, with a 'headache'.

I'll be posting many a question this evening, but are there any tips that may help me keep both eye balls in my head, avoid destruction to the house and possible not maim the dog in anyway?

I am going to try setup the ESC first, but is that right? I need it connected to the motor to hear the beeps, right? So, how can I be sure it won't fire up when I switch it on?

Also, throttle and pitch curves. I have set them up as per finless videos for a nOOb, but loads of people speak of 0,85,85,85 for the throttle. See my posting on Throttle curves. I think I should stick with the finless stuff.

Then, should the throttle channel be reversed?

Which channels ARE reveresed?

I believe I can check if my Throttle Cut button works by using a differnt servo, and ensuring that the head turns all the way to one side and stays there, when I hit the button. But how do I know which way? My luck, I hit cut, and the motor goes the 100% - and stays there!

Any help and tips to keep me in one piece would be great. Will try get the first spin-up on video - for a laugh.

Purely from a saftey aspect move the motor away from the main gear and tighten the bolts then there is no chance of the blades and paddles spinning up by mistake when you are setting up and testing.

[Cralis]

Thanks Smooth - is it easy to move the motor away? Undo the 2 screws, and slide? I'm worried about putting it back in exactly the right position. Shouldn't be too hard eh? As long as it's safer..

[Smoothound]

Yeah, undo, slide, do up. Stops you whacking yourself or worse!! Also make sure you do up as well otherwise motor will move if it spins up and grind away the main gear

[gazza]

Yeh its easy.
When you put it back slip a tiny piece of folded over A4 paper between the pinion and the main gear.
Apply pressure ensuring the gears are intermeshed and tighten the screws Make sure you have the motor square on, ie both screw heads at roughly the same position in the slots.

Throttle hold cant be reversed or be the wrong way around, just set it to zero on your TX. Although I'm not sure if the esc can be programmed with throttle hold engaged as you need to engage full throttle to enter programming mode.

If you have the manual set the throttle curves as advised.
Since you're a learner dont worry about idle up settings yet.
Set normal mode to 0-20-65-85-100.
Infact set both idle up modes to that as well, so if you accidentally catch the switch while flying you wont get caught out.

The throttle should not need reversing, but you'll know if it does as the esc wont let you enter programming mode when you have the TX at full throttle.

Ps ensure TX is turned on and at full throttle BEFORE you connect the lipo to the heli. Also make sure your Lipo is fully charged before connecting up.
I think Mike ships lipos at 50% charged.

That's why I don't like electrickery helis - the idea that a stupid, dumb mistake by me in the shed could launch the thing to full throttle in an instant is scary.

At least I know with nitro that the engine will never ever start, regardless of what I do with the Tx unless I put a starter motor to it.

[marktigere1]

My thoughts exactly!!

[gazza]

Nah its easy once you've done one Or two...erm...

Not to be argumentative or cocky, but, this is the TRex 450 and 600 thread, and I am asking about a 450SE, so I'm not sure why you're talking about Nirto helis. I'm a novice, just looking for safety tips for my heli - not that I should have a nitro or something.

Sorry guys, just trying to gather info on my situation. There's a top on the 600 in this form, where people are trying to see which is best.. Nitro or Elec.

Yeah, that reminds me, where's Thomas?

[marktigere1]

Okay point taken.

Therefore I would advise you get someone else who has experience with electric Heli's to set it up for you and explain what he or she is doing rather than going it alone.

These are not toy's and should be treated with the greatest respect.

A Trex can be very dangerous.

hi
as I recall the hitec tx (I had an optic 6) doesn't need the throttle reversing.

I found I could work out how to set eveything up to get it flying pretty well by from Nigel's excellent setup notes here:
http://www.trextuning.com/setuptrex.php

disengaging the motor pinion is essential. don't run the motor to fast or too long with no load.

[Sesame]

When I set mine up I took the main gear out completely. rather the safety of that than get part of a head hit me.

you obviously have been watching the finless videos if you look at the one for esc's he explains how you can tell whether you need to reverse the throttle of not, as at high throttle it goes into programming mode, at low throttle it goes through the setup to let you know how its been set.

But I would agree if you have never set up one before then seek some real life advice from a club member or local shop before attempting to fly it

[Cralis]

Mmm.. I must be not understanding the forums too well. Sorry then. I though most of those scenarios mentioned in your post might go in the 'General Discussion' or 'Off topic', but hey, those are just headings.

Banter, I can take...
Bring it on...
