interfernce

[chris holley]

Hi i dont no where to put this, so i hope its right.

i have a gancia dei gancia boat running a graupner 9.6v neo motor. with futaba attack 2er on 40mhz No 40.665.

But last few weeks i have been getting a lot of bad interferance an clitching!

I have changed everything, motor, esc, reciver, servo an crystals?

but sometyimes i still get it an i dont no why. My cousion who runs the same setup is fine other than the boat (graupner B24).

please anyideas would be great before i get rid off the boat its no fun now

Have you tried installing filter caps on the motor leads and a schottky diode to fix the problem?

filter caps???

i cant say i have heard off these, where can i get them from an
schottky diode???

Graupner motors usually have the caps already installed (inside the can)

Better change the radio - the attack from Futaba uses AM modulation so try to keep the receiver as far as it's possible from the motor....

ok, what radio do you recomend? the reciver is at the back off the boat, reciver batterys up the nose an servo for steering to th efar left out off the way an motor is central. But its the last few monthes its happend an the setup has not changed

This year I switched from my 15 years old Graupner MC-12 to something called 7X-V2 (I will not put the direct link- you will find it in google)

The best recommendation is:

(go to 2:15 and watch the nose dive)
After 5 seconds under water... no problems with rebinding - that's important during race.
Range test was ok for me - I never go more than 1/8 mile.

ccoooooollllll boat, the 7xv2 has a few to many channels for me only want something simple

[Mieciu]

this is simple radio - believe me.... and the price is also great :-)
