Spektrum Interference - Help

[dayxwalker]

Hope you guys can help I am having no end of problems with interference for the last month or more. I thought it was down to my Acoms 2.4 set and maybe some of it was. I have since bought a Spektrum DX3S 2.4 Ghz in the hope that it will solve my woe's. As you are probably already guest I still have interference. Below is my full spec and some pictures of my layout

B44
Spektrum DX3S
SR3300T Spektrum Receiver
JR Digital Z9000S Servo
Novak GTB (Not sure if it is Spread Spektrum Optimized)
Intellect Lipo's
Nosram Storm 4 Star

I have a Xcelorin 4.5T combo but it is away getting fixed so I cannot try this to rule out the GTB

Anyone got any ideas on what it can be ? Why did novak introduce a spread spektrum GTB was it for interference issues ?

How can I tell if my GTB is spektrum optimized

[Wraggy]

i think sometimes people have to run a power cap from the receiver ? i might be wrong and im sure someone will correct me if i am

Thanks Someone mentioned this at the club but they were not sure. Are you saying if the GTB is not Spektrum optimized then I need a cap ?

Can anyone elaborate ?

I run a NON-Spektrum optimizef GTB, and have done for over a year and have never had interference.....

What servo are you running? Ive heard of people having p[roblems with some servos that draw too much current under load/have too high a torque rating..

are the lipos new have you tried another set of lipos

i had similar problems with a faulty battery pack

The servo is a JR Z9000s its a 10th scale super fast one

JR's fastest racing servo ever uses a specially designed anti-distortion case and tight metal gear train to give racers the perfect blend of lightning quick responsiveness and amazing torque.
Specifications:
Type: Ultra High Speed
Torque: 128 oz/in @ 6V
Speed: .06/60 degrees @ 6V
Dimensions: 0.83x1.59x1.50 in
Weight: 2.2 oz
Gears: Metal Gears

The cells are brand new I have two packs the same and the problem is the same with both but I will tray a set from another racer next week

So what is the point in the spread spektrum GTB ?

Hi all

The power cap on the reciver helps with HIGH Amp Draws from servo (as when you nail it with a good servo the BEC in the spedo cannot cope with all the amps and there for the volts drop and your reciver goes into failsafe , what a cap dose is it stores a little bit of power for when your voltage drops , and when it dose it compensates until your esc gives the full power back , dont know if explained it clearly enough its hard to explain , try a powercap , wheres your arial i know carbon fiber can sometimes interfear , even with 2.4 i put my arial up a straw or i get interferance.

Thanks John
See my pics for the layout and arial location etc .... Pictures speak better than words lol This cap sounds like a good place to start and cheap i suspect ! bit skint after £175 DX3S ! Were can I get one ?
