View Full Version : First Day Was Brutal

I bought a Walkera #60 a few weeks ago at Dymond Motorsports in San
Diego. The speed controller was bad out of the box, so I had to return
it (thanks Nigel for the suggestion). They were very helpful and
installed a new controller. The technician tested it out and trimmed it
for me.

The plan was simple. Take the helicopter to a big empty parking lot,
install training gear, and try to hover 1 foot off the ground. I set it
up and was working the controls a little just to get the feel. I got
caught up in what I was doing and started playing with the trim
controls too. Then I suddenly realized that I had no idea what the
settings were from when that the tech had trimmed the helicopter. That
was the first mistake, not counting of course buying a collective pitch
helicopter trying to fly it on my own without any experience.

Next, the second mistake. I spun up the rotors a few times and cut the
throttle just as it was leaving the ground just to get my feet wet. So
far, so good. Time to try to hover. I increased the throttle until I
was 1 foot off the ground. Then a split second later 1 foot became 3. I
freaked out a little and tried to reduce the throttle. Instead of
slowly decreasing the left stick, I slammed the right stick all the way
down. The helicopter rared up at a 45-degree angle and stalled. The
tips of the rotor blades were chewed up. I looked it over and decided
the blades were okay enough to fly (we'll call that mistake 2b). I've
since learned not to fly with anything less than perfect blades since I
could get impaled if they fly apart at ridiculous speeds. Anyways...

The third mistake was the one that hit me in the wallet. I was able to
consistently get 1 foot off the ground without overdoing the throttle.
I was even able to make it hover for a few seconds a couple of times.
Mostly, though, it was drifting wildly to the side. Luckily, I had
plenty of room, so I would just cut the throttle before it went too
far. No problem except that I was slowly making my way toward the curb
at the edge of the parking lot. The sun was starting to go down and and
I figured that I had enough room for 1 more hover before I called it a
day. I figured wrong. The helicopter drifted faster than I anticipated
and smacked into the curb. It didn't look like it hit very hard at all,
but I ended up with a cracked rotor blade, bent rotor shaft, and broken
landing gear. Only about $25 to replace everything, so not too bad I
guess.

So, where do I go from here? My plan is to get a sim that will work
with my controller (I've looked at Pre-Flight because it's inexpensive
and Reaflight because it seems to be the best one from what I've read).
Until I can hover with the sim, I'm effectively grounded, I don't care
if it takes 6 months. In the meantime, I'll repair the helicopter and
check the LiPo from time to time to make sure the charge is maintained.
Once I can at least hover with the sim, I'm going to get some help
before trying to fly again. I'm sure I can find some place to get
lessons or someone who would be willing to spend an hour or two
babysitting while I give it another go.

Hopefully, another newbie will read my sob story and pay attention to
the warnings that I ignored...

Not a newbie, but I don't have decades of experience (well, not in
helicopters) either. The sim plan is a good idea. FMS is free and
you can get a cable to *possibly* interface with your transmitter for
about $30. I don'tknow what Tx you've got so won't commit to that
statement. :)

Are you practicing with training gear on?? I strongly suggest you do
so until you're comfortable on the stick.

Radd's School of Rotary Flight is a good place to start. Follow the
lessons there to a tee and you'll be hovering in a few days.

Or, to be more precise, helicopters fly *perfectly* in FMS. You'll be
flying the most perfect helicopter ever.

Perhaps FMS will help you get an idea of the orientation, but beyond
that it won't do much for helicopter flight.

it has helped me even using a standard joystick just remember to turn
the wind on and gusts and its a bit more realistic and for the price its ok

Same as the other "name brand" sims. RealFlight is WAY easier than
the real thing right out of the box. I have yet to get any of my
helis dialed in as well as any of the models in RF2, 3 or 3.5.

Good orientation training (regardless of sim) is to trim the helo to
do slow pirouettes (about 20 degrees/sec) and try to hover over one
spot like that. Do it both to the left and to the right then turn on
the wind and repeat the exercise.

I disagree. Learning control coordination, muscle memory etc are all
good things to come from the sim. True, nothing beats burning nitro
or electrons, but the sim IS helpful in more than orientation.

Pre-Flight now has my model and transmitter. I downloaded the demo and
tried it out with the keyboard commands. I know it's a lot different
than using the sticks but I'm starting to think pitch, roll, yaw, etc.
and hovering fairly well. They're doing a promo for the new version on
eBay for $40 including the cable, so I'll start there. Should be here
in a few days.

> Are you practicing with training gear on??

Yes. I probably had a false sense of security and depended on it too
much. Also, I hit the raised edge of the parking lot (where the
concrete goes up about 6 inches to meet the sidewalk). The training
gear hit the wall and the heli pivoted on the gear and smacked the
concrete at an angle.

> Radd's School of Rotary Flight is a good place to start.

I read through it last night. It seems like a reasonable, common-sense
approach. I'll give it a try once I'm operational again and spent more
time on the simulator. Thanks for the suggestion!

The best way to store a Lipo is with app. 40% - 50% charge....

Don't worry...
You will get there if you follow the others advice.....
