Im with merv on this , I have a few versa's, I havent flown an arrow but there is a member already pushing the limits of the arrow and it looks like the FT Foam Board airframe to work out your need for speed issues
I know that Josh got the Versa wing going insanely fast on just the C-pack, and on the Propdrive motor it was almost as fast as David's Spitfire in the speed challenge episode.
Just realized the Versa wing has a forward and backward facing prop. If it wins the poll would you rather see a forward facing or backward facing prop.
I assume the backward facing is faster but I may be wrong
Pusher or puller is a good question on the Versa. I'm gonna say the opposite and say with the same motor the puller is faster because the prop is in clean air. At some speed the drag from the fuselage will be a bigger factor and as one pilot mentioned drag is exponential with velocity. I believe pushers have gotten popular because they look great and its easy to put all the fpv stuff up front. Although its not what you wanted to do I'd like to see both the pusher and puller Versa tested to see which is really faster.
if you make the versa a pusher then you have CG issues. remember it was designed to have a big camera on the front. if you go tractor this solves that problem and you can keep weight down.

Just a thought to add to this. I totally agree puller gets fresh air and pusher doesn't get near as much clear air. But I do think some of the air go over the wing in a puller would also create some turbulent air and potential hinder the speed as well.
In reality were talking about very small differences but even so would be interesting to know which one is better...
