things sitting around waiting to be thrown together

So I just picked up an emaxx 3905 with a novak hv 5.5 setup, Ive had a caster racing ex1.5 waiting to be put together with a mamba 2200 setup but Ive only got the motor
anyways will the novak setup be safe to run in a buggy I figure if it moves the e maxx as fast as it does it should be fine
im using 2x 2s packs and have had zero issues out of it so far
