And what does 3V translate into with respect to the blinky light on the 4 in 1?

(Yes...I used to work in electrical systems at Boeing)

I don't think there's any way to tell the voltage of your battery from the 4 in 1. The light on the 4 in 1 blinks red more when the battery is run down, but it's also a function of throttle position (I think it blinks red when you're demanding more power than the battery can supply?).

I usually fly mine until it noticeably loses lift and can only stay airborne with almost full throttle, then I land immediately.

Ok well that's more or less what I do. I find that RC heli's are WAY less fun when are not in the air.

But that's just me.

Hey again Mike,

If you let the electronics dry out well before trying to light it up again - it may live again!
I dropped my Lama3 in the freshwater pool at work a while ago and blew out the water with compressed air within 5 minutes and it shows no ill effects - even the lipo is great again

Yep. I tore it all down last night after the kids were in bed. A few minutes with the hair dryer. I was up and running again.

Of course I crashed it again today. It was way too windy for it, but I took it out anyway. It was interesting actually. The wind was just strong enough to counter the power of my Extreme motors. I was fighting to keep it in more or less in a hover about 2.5m in the air.. I was succeeding for the most part and then the wind pick up juuuuust slightly....enough to deflect a blade and I experienced a blade stike.....and it fell out of the sky onto the pavement.

I reallt gotta get me one of those 25mm extended inner shafts. I have the 8mm from Extreme. Just ain't cuttin's it.

Hey again Mike,

Get a Turbo shaft - 20mm extension - the longest I know of - from rchelicoptershop.com - it comes from HongKong, so order now! (less waiting). Sorry for the quick post!

Make your own shafts, a lot cheaper.
Get a 2mm steel rod cut it down to 9 inches or thereabouts.
Put some flat spots in the right areas, jobs a good 'un.
It really is quite easy to do, even I did it.

Still doesn't stop you getting knocked out of the air by stronger air....
I'm going outside in the wind now a days, yeah proper wind.
Its fun to try and keep from ditching in the bushes or trees.
I got it caught 2 nights ago on the telephone lines outside my house. (fly-bar weight came off not even pilot error)
Got it down no damage..

Have fun

How do you take the head off the old shaft so you can put it on the home made one? I just bought turbo shaft last Wed. So maybe this week ill see it. Had a crazy crash last night. I was out flying the heck out of my little lama and all of a sudden this house jumped out in front of me....yeah a house

I think it might be time for new motors also. I have been flying about four battries a day and I'm getting some crazy whinning....

I don't think you can.
Buy any metal head upgrades off flea bay for a couple of quid.
I used sssoooo on flea bay and the top bit to hold the fly-bar in place is a bit out.
But nothing a bit a sand paper can't sort out.
Good luck

Hey again Steve,

The Turbo shaft that are awaiting has a SPARE shaft, as well as a shaft with a head attached so you can change them over if you wrap the heli around the top of a 50 foot high tree - plonk, crash, thwap, wallop, crash, thud.

These guys give some sound advice. You can't remove the black plastic head off a standard shaft. You can quite cheaply buy a lama upgrade set (in your choice of colour) from fleabay (incl. ebay Uk & ebay.au

) - just search for "lama upgrade". I think they are around US$10. Then you can undo the small grub screw at the top of shaft under the head to remove the standard length shaft and replace with another - the spare Turbo or a homemade shaft. I have made one from a 2mm Stainless Steel rod (hardware store) that it is very difficult to tell that it didn't come from a shop! I cut the flat spots with a dremmel. The one "problem" that I find with any extended shaft is that the heli doesn't fit back in the box....!

Also oil originals soon, or you will HAVE to replace your motors with Supreme Bearing Motors. They are cheaper and better than all others IMO.......

Peter

P.S. The first pic below shows 3 upgrade sets that I got for my squadron.
P.P.S. The second pic below shows my shaft (on far right) AND a Big Lama Metal Upgrade kit and shaft - sorry, couldn't find the correct pic.

Does 2mm "bar stock" actually come straight enough for our purposes?

(I guess if you guys are doing it, then the answer is yes)

err yes and yes.
When you get a 3 foot long rod it does appear to be a bit bendy.
But once it is cut down to 9" lengths it seems just like my turbo shafts.
Have a go the rod costs under 1 dollar...
Cheers

Hey again Steve,

Light (3in1) oil - sewing machine is ideal. 1 small drop on motor shaft below the pinion (actually on the brass bush)

You may have to use a toothpick to transfer the oil into a tight spot

Hi i need a little help. Just installed two new Xtreme 180 SE Bearing motors. Every thing is mechanical as it should. The problem is that i can´t get full speed on the motors. The bird bearly lifts off and spins around. Like one blade is turning faster than the other. Could the problem be the 4 IN 1 ? Will it loose the effect over time. Have don around 50 + flights with it. But it worked fine untill i replaced the motors.

Hey prolimit,

Sounds to me like you don't have full strength in your motors cause the mesh between the gears is tighter than with the original motors.
Loosen the motor screws and push a sliver of paper between the pinion and main gear. Retighten the motors screws and use the main gear to wind out the paper. Repeat for the other motor

Did you run in those new motors? Remove the blades and run your bird for 5 mins at about ¼-throttle, increase the throttle a bit - and leave it for another 5 mins. Repeat for a total of 20 minutes.

If you do both of these things (and check that the lower hub screws are done up into the locating hole in the outer shaft - and the two screws are lined up with the flat spots on the inner shaft - gear A - underneath the heli) YOU WILL GET FULL POWER AGAIN!!

When you say "the bird bearly lifts off and spins around" - which direction does it rotate? CW or CCW?

Peter

P.S. It is highly unlikely that your 4in1 is playing up - 'cause electronics usually either work or don't.

Hey Peter. Found the solution to my problem. The spring load on one of the brushes on one of the new motors was next to nothing, found out when i tested them out of the heli. RPM around 50 % i think. Now she flys like a dream.

Hey again prolimit,

Great news!

That is a new one on me - new motors with mis-tensioned springs - when I get new stuff I haven't had any problems that I know of in three years!

In that time I have bought about 30 new motors at least - AFCSystems, Supreme, Extreme (for two different birds), and Esky. I have also fitted both springs and new brushes - but never discovered any problems like that in manufacture.

Peter

P.S. Sorry I couldn't be much help afterall.

Hi. I am new(ish) to the coax heli. I have been reading about the inner shaft extension. What I dont understand is why Esky sells a heli with this big of a desing flaw.

it seems like it takes very little direction change to cause the blades to strike. So is this the Fix? Add a few mm to the shaft length?

It is not just "a few mm" grawyl, it is in fact quite a few mm! I finally stopped having blade strikes once I installed a 25mm longer inner shaft. Of course there are a few other things that help because of which you may even end up not having blade strikes anymore with something like the Supershaft 2.0. But if this is the case you probably also have really hard blades, GOOD aluminum blade grips, a shorter flybar. Anything less than 20mm longer I doubt really works, but that is just my very unique, solely personal opinion.

Sven

Hey Grawl,

Sven is right!

A Turboshaft [...Also, have a look at the videos within this link- you can achieve this with an adjustable flybar] OR a Supershaft 2.0 if you already have an upgraded metal head - creates more of a gap between the blade planes. This eliminates blade strike and allows you to fly more "aggressively". - you don't even have to buy another flybar to achieve this - instead buy these flybar bullet weights (when they are back in stock

), cut off the black plastic weights off your existing flybar and slip the bullet weights on, and tighten! You may want to bend "L"-shapes at the ends AFTER you have slipped them on to prevent them coming off accidently as the flybar rotates pretty fast! When you don't want to just hover around any more, start moving the weights inwards towards the hub (effectively reducing the flybar weight but reversible) giving less authority to the flybar.

Peter
