No you dont have to use a tensioner at all if tthe rear sprocket is centered perfectly and you can adjust the rear wheel so that the chain has proper tension without needing a tensioner, sometime you can then put a tensioner on the peddle side chain just to take up any extra slack it may have, some like that setup better and actually this is how I plan to do my next build.
expect to have to work out a bug or 2 before everything is just like you want it but just listen to all the bike smarts you are hearing here and you will be buzzing that sucker around sounding like a coffee can full of mad bumble bee's in no time.
I wish you happy building and safe riding........
