Nice plank. My next project will be a bi plane. Only problem Iv got is. I am running out of space to store all of em. I am lucky that there is no noise restrictions for me. Our club is very laid back.

I thought i'd have a go and bought a twister V2 on Thursday. Laugh, fookin el, I haven't stopped since my first collision with a solid object. I wish the batteries would last longer. 10 mins of chaos followed by an hour of finger drumming.
I spotted this thread on Friday and have done some "fun/crash! learning" and some following of the strange guy's instructions....Usually doing the latter when the battery hasn't got enough power to get me off the ground and into the magnetic obstacles dotted around my workshop floor.
Great fun and a lot less stressfull that when i bought a 30 size nitro some years ago and had to sell it after only one attempt at lift off (afraid of what the damage would cost).
So far I have found the tail boom tends to twist around as there is not enough friction where it pushes into the plastic. I tried tape without much success so have resorted to a spot of super glue and all seems fine so far( I'll be bolloxed if I do some serious damage as it won't come apart easliy for a cheap repair).

Boom twist is quite common on micro's. I know it's a bit late for you now, but in future, get some medium thickness superglue and kicker (instant cure spray for superglue) Take the boom out, put some small dots of superglue on the boom in a line lengthwise, on the area where it pushes into the housing, spray with kicker. Leave it a while to fully cure so it's thoroughly set before pushing the boom back in.

When you need to get yours apart once it's totally boogered, get some pure acetone from Boots and soak the area you superglued, apply it with a cotton bud, keep applying every few minutes - after a while it'll soften the superglue enough to get it out (providing you haven't submerged it in the stuff!!)

Thanks Davi.
I now have splintering boom. I have wrapped it with sellotape and this seems to have beefed it back up a bit.
I'm suprising myself really that I have not had the urge to stamp on it yet.
Hey ho, onwards and upwards.

Davi you're getting far too technical now!

My tail boom was shattered, wondered why the copter wasn't very stable. But just used selotape to strengthen shaft and now all ok.

Dav Dax, buy a couple of extra batteries for the copter, I've got three, speeds up your learning. Dazvi has recommended the makes to buy on an earlier post.

LOL Sellotape, the micro heli equivelant of Duck Tape laugh

If you ever feel the need to do a slightly longer term repair, couple of wraps of tissue paper with a couple of drops of extra thin superglue (Wicking CyanoAcrylate) will have you sorted.

Hi everyone, I've just got my first r/c heli and it is so addictive!!!! It is a EF Sabre and I've managed to hover a few times but not for long. Any tips for a complete novice apart from getting a load of spares from ebay????

Not sure which one you have,
but I had a Four channel machine
and it cost me an absolute fortune in blades,
mind you it was the four blade co-ax type
and I'm extra clumsy depite having a great warehouse to fly it about in.

How are you getting on with it,

I found getting a foot or so off the ground so much easier than skitting about
as you have more control funnily enough

Hi Rich,
This is the one I have got. As you say, getting it a foot off the ground is easier to control than in ground effect. I think the blades need to be balanced better but I just can't get it perfect yet.

As a matter of fact I just bought the exact same machine
but with the Hughes 300 (orange canopy)

I wemt for it, as it has a single set of blades, and a permanently working tail rotor unlike my first unhappy experience model, which relied on the
co-ax blades to keep it from simply spinning out of control.

How are you finding your so far, mine has been utterly uncontrollable so far,
despite the large indoor space, although it can be used outside
according to the bumpf!

Also having trouble adjusting to the controls,
as the previous heli had a different stick layout,
making it extra-amusing

Following my own advice then,
a big open space (Weather permitting)
will see me getting it well airborne and hopefully stopping the
banking to one side or another
which it seems so very keen on just now

How many stacks has it had now...???

Shame that the fella's not getting the hang of it. Depending on where you are, it might be worth getting some instruction. If you're oop north I'd be happy to come over and make sure the darn thing flies straight and give some advice...

I have set it up as per this guide and it has improved the handling quite a lot. Also I increased the AoA on the balancing blades a bit which seems to make it a bit more stable. I'm now able to move it around on the ground with a bit of control. Now getting it a bit higher, maybe a couple of foot and getting used to lots of small movements not a few big ones. It almost seems like you are constantly correcting.

Increasing the angle of attack on the control paddles will actually make it less stable, as it will increase lift available, thus lower head speed needed to achieve hover - the lower the head speed, the less stable the heli. control paddles should be set at zero degrees.

An old trick to increase the stability and maneouverability on these micro's is to trim the main blades shorter, to give LESS lift, then mod the drivetrain to increasing the headspeed even further - my sub micro will hover hands free for an eternity, but the headspeed is insanely fast and I had to scratch build a special head to cope with it. Don't try trimming your blades on yours btw, on a standard setup you wont get out of ground effect.

As to constantly correcting - you will be until you are in forward flight, when you can start to relax a bit as it's been described before, you are effectively trying to balance two perfect spheres on top of each other when hovering a heli.

I got one of these at chrimbo.

I found learning to hover around waist hight, keeping it pointing away from you was the best way to learn control.

I can now confortably fly it around my house, between rooms and land where I choose. Learnt this by putting "X's" on the floor and trying to land on them.

Still working on flying it upstairs.

Great little toy, next one for me is the same but with variable pitch.

Cheers

Guy.

Chaps, what do people think to this one as a first heli:

http://www.rcmods.co.uk/e-sky-belt-cp-with-electro...

looks like a nice bit of kit and (most importantly) the parts seem pretty cheap when it need fixing hehe If not this model, any other electric ones worth considering?

cheers smile

I've not flown that particular one, but have flown others by the same manufacturer some time back. Without actually trying it, it's hard to say but if the parts quality hasn't increased since I last saw them, they are cheap because you will be needing a constant supply - soft as a lump of cottage cheese and just as airworthy.

Have a look at the Trex for a "decent" e-heli. You get what you pay for but at least the Trex is well proven in the cheaper end of the market, I have a couple and love them for a chuckabout / leave in the boot of the car type machine.

I'm also looking for a first heli and this looks pretty appealing. It seems to get good reviews from www.rcgroups.com and plenty of videos of it flying on YouTube.

Has anyone here got one?

Not i.. But ive got my eye on the slightly simpler version. The CP V2. You can get this ready built with everything included, and supposedly set up ready to fly. Apparently the 'ready to fly' bit is a bit vague, but im guessing its still a better point to start with. And still a proper collective pitch model too.
And like the other one, this has good reviews as far as cheap leccy copters go, And theres some good vids on youtube too, as well as guides dotted about the net.
I was looking at them (and other neat ones) on this site.. www.buzzflyer.co.uk
