from 27mhz to 40 mhz
 

ok, many of you will probably know that i am currently looking to move from 27 mhz to 40mhz changing my transmitter. but can i just buy a 40 mhz transmitter or do i need to upgrade my servo and crystals to 40mhz aswell? i am a little lost on this topic and i dont know much about wavelenghts or even transmitters or decent makes. the reason why i want to upgrade is i am having problems when i use my buggy outdoors. it goes around 30ft away and then cuts out to 50% throttle even though i am pressing for full throttle. only when it comes into around 20ft away does it regain full speed without jittering. any help on this would be appreciated. do i need to upgrade to 40mhz? or do i have a different problem. thankyou
(sorry for the essay)

have you checked to see if there is a split in your receiver wire ?? or maybe batteries need changin in tranny ?? Faulty Crystal?? check things like that 1st before shelling out on new stuff ...

Servo will be fine with 40mhz (as well esc), but you will need new crystals. However, this does not seem like a transmitter problem. Like Wraggy said, check all batteries and wires before buying new stuff.

yeah, bateries are fine and i have checked for splits in the antenna, it may be that i have 6 energizer 2100 mah recharbeables and 2 other brand 3000 mah in the tranny?

oh and btw, will i need to change my reciever?

you will if your changing to 40 mhz yeah

okthanks, and will different mah batts affect it?

i dont know how much it will effect it but would advise you get all the same mah batteries.
look at it as the same as the cells you run (you wouldnt run different ones in the same pack.

good advice, thnx

b4rs,
Just a stab in the dark m8 but can you borrow a speedo off anyone and try that.

Just had a similar prob myself was sorting it 2day infact. Mine didnt lose power as such just got glitchy when the car was away from me, changed everything 1 at a time, if it didnt cure it i put it back on so i would know what the fault was.
And the speedo was the last thing but cured the fault !

hth's

esc? well it is a decent one. and i did kinda run a big ass capacitor on it until i realised it could fuk it up. yeah i have the glitchy prob like you.

What esc is it? Did it have the cap on it when new?

lrp super reverse digital. i added the cap.

Mine was a nosram, same manufacturer different colour !

Just a thought thats all, but worth a try.

Must admit it supprised me the speedo was the last thing i thought was wrong and the last thing to change...lol

Its now winging its way back to mirage as i type........Dont you love lifetime warranties....;)

really? could i exchange mine? i meen i did the damage of adding a cap, or donti jus not tell them.

No you cant as you bought yours as part of the B4 kit which means you havent got a warenty card. And you did the damage.
