The Velox question usually stirs quite a bit of debate...it is a great plane, on electric and gas. For electric, the Motrofly 4330 is (I believe) the standard motor that most people recommend. For gas, most people recommend a DLE-20 but some have actually stuffed a DLE30 or even a DLE-35 into this airframe, and I think with careful attention to CG, have been able to fly it just fine.
I think the first questions to ask yourself are:
are you comfortable with 6-8 minute flight times?
if yes, then an electric config is a strong option
if you prefer longer flight times, a gasser is a better option.
this plane flies amazingly well in either configuration, it usually turns out to be what you prefer most.
This very thread was started to answer just that question.
I really don't want to add more weight than I have to on the front of the plane, so I was looking at a plastic spinner or maybe carbon fiber. In plastic, only black or white match. I don't think either one would look right. Aluminum would look sharp, but too heavy. The plane on the 3DHS has no spinner. I'm leaning that way, but wondered if anyone had any thoughts.
Trying to get everything in but the battery and see how it's going to balance.
I just went through this with my electric sbach. The included pilot-RC carbon spinner with the bolt was lighter than the EF electric 3" spinner I had on it. Look at chief's site and see if there is a red painted pilot one available. I would call them to make sure they actually have it in stock. They are very bad about that.
