Hi just wondering if a castle creations sv2 will be good as a replacement for an hpi sprint 2 flux with the vektor 5900kv motor, i run a 7cell battery tnx

My answer probably wont be too helpful mainly cuz ive never used the flux but Ive used the original sidewinder and was awesome, with the castle link, tuning is great, somthing unusual did happen to it so I called castle and they replaced it with the sv2 and actually have not used it yet but will be hooking it up today.

I guess my question is will it be fine with that motor or will something go wrong

Yes it will work fine because that motor is a sensorless and the sv2 is sensorless so everything should work good!
