Been a Futaba man almost all my racing life, if you discount a flirtation with JR in the 1980s. I find them very (very!) reliable, and all their kit does exactly what it says on the tin. My Txs have been put through an oscilloscope at a couple of big meetings and all passed that test with flying colours.
I would recommend a 3VCS (I have one) as it will take either the Futaba or Spektrum 2.4 system (I use Spektrum). My tip would be always to use a Futaba receiver if running 40Mhz, and preferably Futaba servos. However, I ran KO servos with no issues for many years in Off-Road and TC using the Futaba FF3 and a Futaba receiver.
Txs are one of those things that people swear by one make or the other, and it's not often that people agree with each other!! I swear by Futaba, and hope that my experience helps. If you've any other questions on Futaba kit, please post here or PM me, and if I can offer advice, I will.
One thing's for sure - judging by the numbers you see at all the RC classes, Futaba and KO are the most popular Txs. If eitehr of them were riddled with faults, then we'd all be running something else! It's tough choosing between two great products, isn't it!! HTH
