Yeah it should be suitable, but its probably abit on the big side

That is definitely not the case for this FPV transmitter, but as I said it seems an OK price if you get both the TX and RX in a package. And if it will fit on your FPV racer then go ahead, but you can get much smaller transmitters for around the same price.
