Ikarus Eco 8 and gyro problem......

Post by missing beet » Sat, 05 Jul 2003 04:21:51



I'm new to R/C helos but have lots of fixed wing
experience. I have been practicing on the Great
Planes G2 Flight sim and I am  comfortable flying
the helo simulators.

I have a Ikarus Eco 8 with Ikarus gyro. I have
fiddled with the gain and sens setting and the
tail rotor servo rate setting on the radio (Futaba
9CHP). I  am always having to make rotor
corrections as the helo spins one way or the other
in flight.

I have flown the Eco 8 about 10 times and have had
minor crashes 3 times. Each time repairs were
simple. I attribute all the crashes to the fact
that the helos will not track straight.

Will a Futaba heading hold gyro make a great
difference?                  

Responses appreciated.

Looks like I see my answer in the other
posts......Futab GY 401 sounds like the solution
to my problem.......

The Eco 8 tail is not that good, a dare say a GY401 will help, but
you'll need a good fast micro servo for the tail too, otherwise the
gyro won't be able to do its stuff.

Thanks for the reply David, I plan on getting the
GY401 with the S9253 servo. I just hate spending
that much $$ but I already have a bunch into it so
what the heck, can't take it with you, might as
well spend it......

Also when I get rich form the stock market (
pppppppppfffffftttttt ), I plan on getting a gas
helo 60 size, but that will be a year or 2 from
now.

Hello,

Be advised that some Ikarus gyros have the gain and neutral adjustments
reversed of what is labeled on the gyro case. In other words, when you think
you are adjusting gyro sensitivity, you are in fact changing gyro neutral
servo position and vice versa. Once you "play" with the right adjustments,
you'll find your gyro operates quite well.

Also you might consider moving the tail rotor servo to the rear of the
chassis, just before the tail boom, this will make tail pitch control
smoother, and improve tail rotor response, as the original linkage is not
"optimal".

Hope this helps,
Regards,

Patrick
