HI flyers !

I felt that i would sorta blog my experiences with this heli (the walkera 22e) and lead you thru my learning process. I am new to the hobby and this is my first rc heli experience. I had never even seen one fly in person, but apon seeing that they existed in an affordable range ,(so it seemed at the time) i have now begun what i hope to be a long relationship with the rc heli world. Ill show you some of my thaughts and noobtacular responses to my introduction to these robo-engineering-micro-mechanical-works of art.

- After my first experience i ran to my computer (gen 1 dual 2g mac G5) and found HELIFREAK ...from watching google vids i think. My introduction to these forums was the best thing i could have imagined as you can see here:

http://www.helifreak.com/viewtopic.php?t=23670

OK, so here it is.

Day one: "It's alive"

Standing outside my shop here in providence RI, UPS man walks toward me with the box i had been squirming in my sleep awaiting. Immediately open the box to find my new "toy" staring me in the face.

I immediately noticed the fragile nature of the machine i would be flying.
so many little plastic pieces!

I bring it into my living room and spread out the contents of the box.
-the heli
-the controller
-the bag of -useless- spare parts (they ship outdated spare parts with it)
-spare blades "why, i bet ill need these!"
-battery charger -seemed dinky compared to my old rc car charger
-training gear -thank god they came with
-operating manual, and fight manual

ok so ...Start reading!
-safety blah blah blah... just kidding
-battery charging ...plug her in and get that baby juiced
-adjusting and tuning

so here's where the fun begins!
mode 1 ? mode 2? oh im in America...mode 2 it is.
wait... i have to wait for the bat to charge before i can even tune anything?
ok, so read on.
tune her up and get flying ...simple enough! (heh)
so i read on about how she flies and how to do certain maneuvers.

Now, if you have never had any kind of rc machine at all, (which fortunately i have ,but limited to my elec rc car...and i had an air boat once) most of the language the directions are in would be foreign to you.
"never touch spinning rotor blades or any other exposed moving parts"
THAT everyone should be able to understand.
"initially you do not need to worry about how to operate your [22E] skillfully"
IT ACTUALLY SAYS THAT !
Well what do i need to worry about?
hmm... ill just worry about everything else!

So, i had read elsewhere that one should not even attempt to fly their craft w/ out ever putting some time in on a simulator.
Well with the heli right there... and the battery charged... and no such sim for my MAC... what do you think i did?

i plugged the bat in and jumped right in!
with the manual right in front of me i slowly went thru the steps.
-turn on the transmitter...-check
-throttle stick down... "um wheres the throttle...oh...ok...DOWN" ...-check
-3d mode switch down (no where on the receiver does it say 3d switch... but the picture in the manual shows it) ...-check
-test flight controls to make sure operating properly ...ok things move when i move the sticks... im no moron... but what do i know about what properly is? ...so i assess the bade movement, direction, and with my general understanding of earthly physics and what i think a helicopter should do, i deduct that everything is AOK.

manual reads "...and will move swash plate in the direction you want to fly"
what the hell is a "swash plate"? ok it must be one of these thingies near the blades...

no where to this point has there been even a diagram of the heli...
...a nice picture with descriptions would be nice there walkera... or maybe an exploded view of the parts im going to be replacing!

so.. whatever... the "swash plate" should be moving right... it said RTF !!!
(wow)

moving on.
next step:

-"push left control stick slightly forward to increase rotor speed. The [22e] may not take off vertically; it may go forwards or backwards,left or right. Use trim sliders (you know... those things next to the sticks) to fine tune the [22e] while hovering.

"WHILE HOVERING" ! ? !!! ?????



this is where things get interesting.

so i trim the rotors down to stop. Push the throttle up...

WHAM!!!

one of the main blades disconnects, flies across my living room, and disappears out of sight.

huh...i must have done something wrong.

I find my blade (ding-1, blade-1) , and inspect the situation.

IT WASN'T SCREWED ON TO THE ROTOR HEAD!!!!!
no joke... the screw was just chillin ! ...

THESE ARE RTF ! (so it says on the box)
i didnt feel as tho i was supposed to inspect every aspect of the construction.

"dont panic...it will be fine...shit happens"
now my experience with taking every electrical thing i could get my hands on, and the fact that i have a complete cabinet building/woodwork shop, is the separation between me and some poor kid that gets this RTF heli. I have tools.

So i dive into the fixit part of the game, before i ever even get the blades at full speed.

inspection of the head leads to an amazing discovery.
a- the screw to blade 1 was not tightened at all
b- the screw for blade 2 is stripped to round...

no problem for now... at least its on there!
so , screw it on there and proceed.


-power up, trim the throttle...
up throttle
up throttle
up throttle
..ok it's "light"
and twitching, sliding to one side
trim
trim
trim
trim
trim
up throttle
trim... oh crap... move sticks erratically..

SMASH

into the wall

(blade 1-ding2,3,4 blade2-ding 1,2)
im not going to keep counting dings.... just blades.. just insight on my thought process


-inspect... shits broke...
-google "replacement parts for 22e"
-grab the super glue

-google "rc heli crashes"
-"oooh"... laugh my ass off
-feel better that mine was a gift
-find HELIFREAK site
-


END OF DAY ONE

One might ask... "why would you continue?"
well... i love to fix, make, tinker.
There is potential here...
if it flew out of the box... around the room, and landed, i might have been bored with it. This is a complex machine, that all parts are there in front of me, ready to fix, replace,improve...and purchase. Im no millionare (yet), but ive dreamed of such a machine from childhood. If learning the hard way is what ive been dealt. The hard way it is. Maybe it will just make the evolution of my experience that much more enjoyable. (nor do i have the extra grand to buy the into the big boys)

Thanks fer reading!

More to come... prob by the week not day, but i know there are plenty of ppl that will get a kick out of this, if at least make them feel better about their first days.

Hey Andy,

Glad to see you have a strong sense of humour and some common sense. The 22e, like all Walkera helis, does not have a good reputation for quality or flight characteristics so odds are you have a challenge on your hands. I had a W5-III which was OK but the radio seemed unreliable and was prone to glitching. Unless you are fairly lucky, you will need at least new servos and possibly a complete Tx/Rx replacement. If you have the brushed motor and NiCd or NiMH battery then the flights will be short and wimpy. Some people do a brushless+LiPo upgrade, personally I would save the money for a next-step heli.

You will find a lot of info about Walkera helis, including the 22e, on rcgroups.com and there's also quite good info available on the walkera forums on walkera.com.

In all likelihood you will end up with another heli that is higher quality and will give you more air time and less bench time than the 22e, but you will certainly learn a lot along the way.

If you do look for something better, I would recommend a TRex SA or SE with HS65MG servos and a DX7 radio. Gives you something to browse the web for while waiting for your 22e to charge (or maybe for the glue to dry).

Good luck with your journey, hope it's lots of fun.

So ive found the local "flyer's" hobby shop.
No walkeras there.
They seem to just be getting into the helis.
Large amount of trex and align parts.
eflight stuff... blade cp and whatnot.
The guys there are busy helping "old timers" with there planes, and talkin tech with the local kids about their rc cars/trucks.
The one guy who is behind the counter of heli parts does not own one, so little experienced help -there.


Did some investigating, and found a handfull of great parts to keep me flying instead of ordering parts.

-many lenghts of 2mm screws
-metal ball joints to replce the silly plastic ones that break somtimes even disconnecting them.
-threaded rods
-set screws

between these parts and the saint on this forum named broncaholic who has donated me an entire 22e, i think i can keep her flying (or sliding around on the floor) for quite some time.



I got home today from the hobby shop and set her up as best as i could, connected the battery ...

I think my transmitter must be too low on batteries. begining the "flight" , i got erratic movement, then the heli just lifted off.
GREAt straight up flight, with no tail rotation... but i wasnt in control...
panic, throttle down , and shes still spining on the floor... slides into a peice of foamcore leaning against the wall, and the tail rotor goes flying.
Not so bad, nothing broke, all went back together.
need some AA batteries for sure!


Im going to have to find some local heli flyers elsewhere.
Thinking of just starting up a club/group as i have a great meeting spot here at my art gallery/loft space. We coiuld even fly our micros in the main gallery!

anyone who has flown this heli at all, i would appreciate any feedback on what it took to get this flying steady. I have seen vids of people flying a 22e well, and i have faith that i can get her up.
