Hi,

I just bought an electric heli to begin practicing this great hobby but as a newbie I dont know much about RC Helis...

What happened was that when I started giving the helicopter more throttle, it slided in the floor in one direction aided by the training landing gear (it doesnt remains stable).
I always have to compensate with the controls,.I lifted off the ground once, but immediately landed because it headed again in one direction (flying) and very fast...

Is this normal and I need to learn to compensate this "natural slide" or do I need to adjust certain piece of the rotors? Please help...

My simulator just went straight up without slides... (FMS).

I too am learning to hover and yes you will need to correct for that with controls it is called translational tendency the tail rotor actually blows the heli opposite of it kind of like a prop on a plank it only takes the slightest correction to hold it I have found myself using movements that can't be felt but can be seen hopefully one of the pros can give more insight to this but it is not abnormal

Yeah

Yeah, its normal. I mean it shouldn't be jetting off, but it slides a little and needs to be corrected until you lift off a little.

Is your swashplate level at mid stick (the direction the swash plate is pointed in is the direction the heli will go). What kind of heli is it. I assume a micro since you are flying in your house.
The micro electrics are sometimes harder than bigger version because on the bigger version there is less room for error, everything fits perfectly into a slot or is screwed in and aligned perfectly. The smaller ones have a greater tendency to have slop in them. You also have to align some stuff yourself, and if you don't really know what your doing, sometimes you don't pic the optimum spot. Anyways, you can get through it, but you'll prob spend some money doing it.

It takes sort of a leap of faith to punch the throttle and make the transition from this shaky hoping around to a hover. Helicopters aren't very stable at low rpm and really close to the ground (ground effects). When you get the rpm's up a little, you have a lot more stable heli because of the increased rotational inertia. I have a hornet and it flys really bad until I crank the rpm up to at least 2200. This can be scary as a crash at higher rpm's will definitely cause more damage. I guess it takes experience to tell if your heli seems like its working correctly or not and to decide if you want to try to lift off, because if its not perfectly set up, you could be putting it in a position for serious damage.

What kind of radio, gyro, esc (assuming stock), motor esc (assuming stock), battery are you flying with.

There is a whole check list of stuff I really have to make sure is working on my hornet or else it flies like crap. Everything has to be perfect.

FMS is hardly a simulator. It can teach you orientation of flying, but it doesn't compare to real flying in terms of touchyness. In FMS you can push up and rise really high and then push down slowly (without ever touching cyclics) and you will not only land safely but will land in the same spot! Very unrealistic. You have to be constantly adding cyclic inputs to keep you heli stable. I suggest you get a more realistic sim.

I was in your play a short while ago and I wanted to take the cheapest route to success, but when you skimp in helis it just makes life more frustrating. Do it right and you are sure to become a heli fanatic, skimp and buy crappy stuff and your gonna find it very frustrating. I have CSM v.10 but if you can find V.9 used, it is very cheap is very very realistic. I am not an expert on other sims but I know Realflight is good (but expensive and requires a good computer) and there are some other new ones out.

Make it idiot-proof, and someone will make a better idiot

yes this is normal it will striaghten up some once you lift off,dont be shy just go for it in a room with plenty of space, soon you will be hovering and loving it try to just hover about 1 foot of the ground till you get familliar with controlling the heli then climb up a little higher, good luck joey

Yeap

Thanks for answering, well I now think its an alignment problem because youre talking about minor corrections with the controller and I usually have to go all the way with the sticks... I was trying to follow the directions of a site that's called Radd's Flight School or something like that... the first lesson is to slide the heli without actually hovering it, to get confortable with the controls and to stabilize the heli, but as I said its too difficult, it may be an alignment problem as helicopter34 said.

My heli is as crappy as it can get :P its an Smartech Aero-Hawk with all the cheap plastic parts and cheap radio, and all-in-one gyro-mixer-ics, but really I couldn't afford anything better by now. On the US and most internet sites (ebay and such) this heli its around $140-$180 dlls but I got mine at around $360 bucks because of all the crappy taxes here in my country. Imagine how much a decent heli costs here ($800 dlls for a used! nexus 30, without electronics, $1,100 with electronics...)

I'm hoping to get better at this and to sell one kidney in order to afford something better (just kiddin), but I hope to pay a visit to the US and buy everything there and fly the heli across the border....hows that :P

Thanks to all for answering...I'll keep you informed of my advances (or crashes) hehe.

i think that rads flight school is refering to learning on nitros when they say to scoot around on the ground first as nitros dont pull to the left radically like an aerohawk, an aerohawk is what i fly and they require a little upgrading to fly decent, i would just go ahead and get it at least a foor off the ground or your going to go nuts fighting it trying to learn to control it on the ground take a look at my gallery and you can see how i rapped my blades it helps alot making the heli fly more stable and takes alot of vibration away good luck joey

Heli slide

Hi Jorg3, Ive got a aero hawk too and learning to fly it. the two up grades i would recommend are a swash plate with a ball in it and adjustable linkages, they made the biggest impovement in my birds controlls. as far as Radd's school of rotory flight goes there is a section for micros. i'm on my third day of practicing sliding around on the floor and it works. i came into work early today to get in a batteries worth of practice before we opened and my fingers were making adjustments on the sticks almost without thinking about what i was doing. so it dose work, just stick with it, i was throttled up more than i was yesterday so the trainning gear was bearly touching the floor. hang in there you'll get it. Al.
