Sapac 70mm Viper Jet

I've started another winter project. This is the Sapac 70mm Viper Jet that will be equipped with Hitec servos (HS-5065MG and HS-65MG). I am also installing the scale Sapac air retracts/brakes and scale Sapac struts. So far I've prepared both wings to accept the ail/flap servos and retracts. I've mounted 3 of the 4 (waiting on an order) wing servos onto the servo covers. I still need to do a little work on the strut area to make it where it will fit the trailing link when the retract is in the up position. I think I'm going to be beefing up the nose retract mount as well because when I was pre-drilling (by hand) for the mount screws the thin stock ply mount cracked and some of it actually fell off. I will probably build it up with some 1/4" ply. I did a dry fit of everything to check out the AOA when it is sitting on the ground and at looks as if the 1/4" ply wont give it too much AOA, it might actually set it where it really needs to be. As you can see from the profile pic the nose seems to sit a little low any way.

Nice gold/black verison. I'm building a white with red trim version. Thinking of using hs-65hb servos (originally HXT900s but decided not to cheap out). How are the 65MGs? Do they center well? That's my major concern for not using MG servos.

Yeah, they center well. I'm actually using the 5065's for most surfaces and a 5085 for the elevator.

Will other struts and retracts work in this jet? Suggestions?

I'm sure you could find different struts that would work but I haven't been able to find different retracts that would work without some modification. There is another Sapac Viper Jet thread that someone used different retracts but he had to mod his... The biggest issue is the depth because of the thin wings...
