Micro Helicopters advice please ??

I've flown my easy copter outside but it was calm and I still had to give it full forward to keep in the hover.
I've also flown my noname fixed pitch "outdoor" heli inside but it was a very large room. Think basket ball court rather than front room.

Just one query - I'm presuming that the walkera is unsuitable for flying outdoors sue to its small size and the honeybee is a bit on the large size for indoor flight - but is the Lama suitable for both indoors and outdoors?

It could fly outdoors with zero wind... I think most small fixed pitch heli's get really affected by even a light wind so really need collective pitch.

Problem is the bigger machines are just too fragile for learning, one big crash and so many broken bits you'd spend most your time grounded and would cost a fortune.
 
Oh and for the tail rotor. Get a piece of sheathing from some electrical wire like 3 core. Pop it on the end and depending on the fit, use some ca (glue).

well done on getting it running.. and flying fig 8s already, dam your good! :), how you finding straight hovering ?

there is no clip or anything on tail rotor, it's just a friction fit, maybe you could bodge something to stop it moving off the axle, not sure what but thats half the fun :)


the axle should like the bottom piccy below..

I can hold a straight hover for like 2seconds then it tends to pull to one side and I wobble all over the place :eek:

not sure why they didn't design a clip for the open end of it though :(, maybe a very thin piece of tubing would do it (or use some insulation from some wire pushed over axle)

I broke my tail pin today so I have just orederd a new oe well 2 as it happens and the following:
Main motor
Tail motor
Tail boom
CNC balde holders
Screw set
Tail Rotor
Total was around £18 should keep me going got them from http://www.chinesejade.com/walkera4_3_A_B.htm
just hope they come soon said 7-20 days although could be sooner depending on customs.

I will try the piece of tubing or sheathing from some electrical wire like 3 core like SimonCHere said.

But for now I am grounded until parts arrive :(
 
it is possible to bodge a temp tail axle using some wire from a paperclip or something.. should at least get you in air. just put a little bend at end, thread it through and bend at other end.

if you desperate you could always get one from buzz flyer...

concentrate on hover first and forget moving heli about, once you can hover a whole battery out no crashes then it's time to move on to sideways hovers (once those done you can start moving heli about abit left to right and back again)

thats a good idea I might well make somthing up to see me back in the air..if I cant I will order one from buzzfly I have a feeling that one more spare pin isnt going to hurt ;)

I will practise the hovering when I get her back in the air

I've been very lucky by the sounds of the breakages you guys are having. So far I've only broken the canopy which was easily fixed with a bit of sticky tape and the bit that sticks down under the tail rotor. It hasn't stopped me flying yet, but I need to put something on there (like a paperclip as suggested) before I break the tail rotor.

Does anyone know what the tail knighthead set is? Is this the replacement for the tail rotor protector that I've broken? Pictures seem slightly different to the original which has put me off buying it.
 
yeah it's a new axle for the tail and the tail 'skid'. (for the 4#3a not sure what it looks like on 'b', but should be much the same)

you could always just order a flybar, it's the same thickness as the skid and the axle, then chop up bits to length whenever you need them... (i put a dab of CA on the end of skid so it didn't fray any more.. seems to have worked)

prolly even cheaper so find someone thats sells CF rod of that diameter.. then you sorted for axles, flybar and skids forever for almost no cost.. gonna have a search about

nice flying wish I had a industrial unit or even better a sports hall to have a go in. I can see clubs popping up all over the place could hire a sports hall or even village hall have a good fly.

I think that rod may be a bit thick ??
 
cheers, looks more uncontrolled on camera, but that last crazy circuit was too big for space and got in a huge sideways drift as it past nose in :)

just broke my tail motor, first one.. so grounded now also

not sure on the CF rod, im sure it's 1mm on the heli, at least appears to be.

not sure, should be soon, just had a bunch of parts in from chinesejade, took 6 days to uk, not bad..

once I get a new tail motor gonna protect it by glueing something on back of it to stop it getting knocked... thats what done it over :(

just taken opportunity to put little drops of wd40 on all moving parts, makes the heli run a lot smoother..
 
went to a model shop today and got a 30cm metal rod for 40p and made my own pin for the tail rotor.

couple of pics not the best but you get the idea dont think this will ever brake!

good idea, one bit of advice though.. the pin itself sits in two bearings in the plastic housing so it rotates within the bearing rather than the gear being forced round the axle...

the way you have it in top picture the axle can't rotate as it's hitting the motor casing, so you need to trim it just after the bend you put in so it can revolve... if you don't do this it's possible the gear might melt or wear as the axle can't move...

just a thought, could be wrong :-)

Hmmm I think I kno what you mean I will have a look in the morning..saying that though my new pin should come in the post as I ordered another one as well from buzzfly.

tonight I have had real trouble hovering just cant get it for some reason. can you break down your technique?
 
it's hard to explain hovering as it's just a case of getting the knack of it.. I remember when I started on a picolo heli a few years back i struggled for a week.

few tips though

- your primary focus should be keep the tail pointing towards you, as soon as you start losing tail and you know you cant get it back land the heli or you will crash.. you should only move the tail away from you once you can hover a whole batt pack non stop no crashes.

- these little fixed pitch helis are slow to respond to the cyclic (right stick on your controller) when the rotor speed is low... this means when you only just off the ground at low level you end up moving stick all over the place 'long throw' to try and keep it in one place. your much better with these heli's (assuming you are familiar with sticks) to lift off a couple of feet off ground. Flying at this height means rotor speed is up and cyclic responce is much better meaning you only need tiny movements on right stick to keep heli in same position.

- the heli will pull to one side as you lift off, just get it in air past this stage while compensating for the direction it's trying to scoot off in

- if using training gear the heli can get into a 'rocky' motion as so much weight at bottom of heli... try not to let it start by making small movements with cyclic

- don't overcompensate for direction changes. often to stop a heli 'sliding' one direction you have to apply the opposite to stop it quickly.. if either you apply to much, or hold this opposite motion too long you over compensate and you end up with heli moving opposite direction and in same trouble. once your rotor speed is up and your a couple of feet up you should be able to make only tiny adjustments to keep it in hover, also at this height you get the heli out of ground effect that really upsets any heli

- if your getting close to a wall best to set it down rather than crash full speed into it :) (or what I do loads on these, catch it)


edit: with the axle thing, cut it where I put the red dot below so it can spin freely...

edit again:

mechanically make sure the flybar paddles are both straight when heli is initialized (or slightly angled up if you prefer that feel never tried it though), and the distance from the base of each paddle to the rotor head the same on each side.. mine was out by about 1.5mm from factory, but not much.

make sure the whole rotor head pivots freely, if you flick it down at one side it should bounce up when it hits bottom showing it's nice and loose

when heli initialized the swashplate (the plate below the rotor head that tilts it) should be horizontal.. if it's not the heli will drift madly and be hard to trim

make sure the collar on axle about half way down has not slipped allowing up / down play in the axle, that would make your controls feel like jelly

if your heli is setup nice you should not have to mess with transmitter trims, i always seen these as a fix for a poorly balanced machine.. maybe wrong with this assumption, but I prefer a heli that doesn't need 'cheats' to stop it wandering about too much.

found a few vids on youtube of people using lamas outside (I'm guessing in low wind) - have decided to go for a lama as the first hele will just practice inside (+ in the atrium at work once I'm used to it)

Hopefully then progress to a non co-ax fixed pitch one then later perhpas onto a proper one

Also found this vid on youtube so thought I'd share (Hele fishing!)
