Now I am rethinking all of this. I can go with mechanicals for about $60 - 90 or go with air for about $150. This originally started out as a "budget buy" so I guess I should stick to my original plan and go budget. Like I said before, I have a Sig P-51b that I want to do it right and put in good gear.

I just remembered that the SIG came with mechanicals so I can try those first in the VQ and if they don't fit, I will buy the VQ retracts. This will save me some cash! They are 3/16 wire struts so they should have some strength. The Sig is a .60 size plane but should that matter? The retracts are usually similar dimensions right?
