aile direction reversal

Hey guys

Decided to do the tx mod in case I happen to buy a bunch of "wrong way round" servos. That way I have a radio for either scenario .

So that's the tx open, now which 2 wires do I have to change to reverse the direction of the aile so my servo doesn't make me drift in the wrong direction? Are they at the stick or is it something on the pcb itself?

Thanks
Fin

There is also a part part of the meadow that "goes" into this forest.
Imagine a square of about 150 m (450 feet) each side, 3 sides with trees and one side toward the meadow.
This square is convenient when it's windy, the trees give some protection.
A very nice place !

So when can I come to visit, Nachbar?

Sorry to hear about the crash, but talk about damage limitation? These really ARE seriously tough birds

Rookie Mistake

Think I should still use this pack and can I squish it back together? The voltages seem to be fine. I will tell you what happened if you really want to know.

find the potentiometer for the servo you wish to reverse.
You will see 2 wires, on to one side and one at the center. On the opposite side, there is an open terminal. Remove the outside wire and resolder it to the terminal on the opposite side. It is then reversed.

I would charge it carefully and monitor it. I have had several batteries puff and they start to get hot. I dispose of them. If they have internal damage, they can start on fire when you are discharging and then you will have a flying torch.

Thanks Brent, a great help for someone who knows what he's looking for... I unfortunately don't

I googled potentiometer to get some pics and meantime THINK that the potis are the things to the right and bottom of the stick housing with black, red and yellow wires on them (if you zoom in on the pics you can see them very well).

If this is correct:

1. how do I find out which one I want to change? I think probably the one at the bottom, as it seems to be attached to the lateral rocker mechanism.

2. exactly which wires do I want to move, as it's not quite clear to me from the description? Do I just move the black (outside?) wire up to the free terminal above it, do I move the black and yellow wires, or do I move all three?

If these are not the potis, can somebody please describe where on the picture they are?

Appreciate it guys.
Fin

You see at 2 sides of each stick there are 2 little PCBs with 3 wires arriving, yellow - red - black.
On the other side of these PCBs are the potentiometers.
You just have to invert the yellow and the black one on the PCB where sits the potentiometer of the aile.

Roland

Edit :
Tigger you posted at the same time as me !
to find the potentiometer of the aile, move your aile stick, it's the one were the axis is turning (hope I'm clear enough ?)
If you are in mode 2 (Mode 4 on the TX) it's the one at the bottom of the first foto.

Edit 2 : F45 allready repaired, I had spare blades !
And you can come to visit when you want.
There is even a Bierstube at 300 meters ! (Like I said, a nice place !)

This is crash damage. So maybe I should dispose of.

It means that the power supply is built into the charger.

Thanks for the info. Just ordered myself an original IMAX B6, so hopefully I'll be as happy with it as you are with yours. Good to know they deliver what they promise

Happy flying, hope the weather over your way is a bit less wet than ours.

That is awesome. I am trying to decide what heli to get next. I thought I had settled on the V912 but the F45 looks great. And taking aerial video would be icing on the cake. I think a V912 would be great for backyard flying. After watching the video of the F45 my backyard doesn't seem big enough anymore. Now I know why guys have so many helis, too many good choices.

ermmmm Steve, be careful, that cell got too hot... I would exercise extreem caution. These batteries can get so hot that they burst and cause fires.
btw all arrived in perfect condition i got my 'fix' and the vid to prove it

question for xtreme blade user's

I love my F645 for the most part, but am not real happy with its wind handling characteristics. You fellas using the 10dg extreme blades, do you find the performance that much better, esp in the wind? With the stock high lift concave airfoil blades, the heli wants to climb like crazy in a head wind, and dances around all over the place in anything over about 5mph. Are the extreme blades concave or symetrical? Do you find they handle better in the wind than the stock blades? When I get by bl motor kit I want to try a set of the 10dg blades, but I understood some to be using the 8dg blades using a different pinion to increase head speed with the bl motor. Please let me know if the 10dg blades will be a waist of my money, or should I get the 8dg and a new pinion than what comes with the kit. Thanks all, nice to be able to glean from others experiences.

Fin, if you want to make this switchable at the tx, look up 'D.C. motor reversing switch'. this application uses the exact same config. its a simple dpdt (double pole double throw) switch with a 'X' jumper connection. I intend to mod my tx to do that as i got other applications to sort. Give me a tic to relax and i will open a tx and give you the exact colour wires ect
cheers lad

oh cool, the lads sorted you

Actually it was crushed in a nose first crash, not hot. I will probably toss it to be safe. Thanks for the caution though.
