+1. I have the same setup as Gyro on mine. It is the *perfect* electric setup for a Velox. The Velox comes out lighter and is very fun with this motor. Very fast in the air, violent, pop top machine. 6s5300 glacier 30c packs from buddyrc are what I run, and they are great.Highly recommend the 6s5000mah setup on this bird, it's tons of power and keeps the plane light and fun.
Motrofly 4325-425kv with an 18x10 or 19x8 is the way to go!
It'll also cost less vs a 8s setup depending on ESC choice.
Personally, I'm running the Motrofly on 6s5000 packs, and a Gecko 155a ESC (a little overkill, but it's very light and has a powerful internal 8a/16a BEC.
The ones I've seen on a DLE-30 fly a bit heavy. The whole setup is noticeably heavier than a light 6s5000 setup. And it shows in the slow/low speed stuff. If you do more high energy stuff, then the DLE-30 would be fine. But for low and slow, the electric is better.So you wouldn't recommend the dle30
