Which transmitter?

[Pops]

Hi..We started with a KO esprit on 40fm and suffered interference(sods law it was mostly in finals!)
Moved to another KO which is converted to spectrum..Had range issues so bought new recievers and an ariel for the module and in the last 2 events its run perfect all day only to go into failsafe in both A finals!!! Gutted!
So can you guys reccomend a 2.4ghz tranny? Been looking at the KO universe on Ko 2.4ghz. Really dont want to buy the wrong thing!
Thanks Dave

Dave, forgot to ask you yesterday whether you run a powercap in your receivers. Its basically a capacitor that plugs into a spare channel on the RX and helps eliminate voltage spikes and voltage drops.

Looks like this. Availbale here for just £6.49 http://cgi.ebay.co.uk/Spektrum-Volta...562ef6ffb1153e

Could you tell me what value and voltage these power caps are?

Well i was too tight to buy one so i bought a capacitor from Maplin and solders a lead on. I got the 47 Capacitence with 16v rating and it's worked a treat.

Ive used Futaba and KO over the years but always felt the Futaba stuff had a better quality feel to it.
Lots of people run Spektrum and Futaba's 2.4ghz module in the 3vc
Iv heard and seen more problems with the spectrum system than the futaba one, but the Futaba one is more expensive to buy if you have a 40mhz 3vc and want to upgrade to 2.4ghz!
There are lots of people who don't have any problems at all with both systems which ever way you go you will have a very good Tx

3vcs seem dirt cheap without the 2.4 setup so if funds are tight you could always stick with 27/40mhz and find out if you like the tranny before you commit to 2.4.

also with this tranny I put a £20 ebay lipo in which runs it for 15hrs before it needs a recharge. I hate having to recharge the tranny every other meeting as I found with my old KO, but that probably could of been solved with a proper set of AA's

If money isn't a problem get yourself a Futaba 3vcs

or take a look at the Futaba 3gr.

KO Universe
I've got the spektrum module but they've got their own 2.4g system now, it's not compatible with spektrum receivers though (nor is the Futaba 2.4g) so you'd be looking at new receivers too!
Tried the 3VCS and didn't get on with it after being used to KOs.

But as Jamie says try the power cap first.

[Pops]

So it looks like Owen is getting either the Futaba 3cvs or the KO universe.
Which one though?

Jamie i'l try the power cap(Looks like i'm getting anoyher of Owens hand me downs!) Thanks for the link bud

Dave, i just now realised i had a spare powercap in my box. Been looking for the bugger for ages and found it earlier whilst cleaning the grass out of it.lol

But try the powercap, im almost certain that will sort it, and remember to re-bind your receivers with the throttle stick on brake or neutral to set the failsafe.

Yes.. Rebind failsafe to neutral not full throttle Funny how the both times its happened its been on a full power part of the track suggesting a power decrease at the reciever as you have said..Just ordered the power cap so fingers crossed it wont happen at Cobra wrca,dont think the poor lad could take anymore dissapointment
