here they are on the plane. I don't know if they are Jet A proof but I am not going to seal them. If they fade or get ruined I will print and cut another set. They were cheap and quick to make.

I propped up the fuse on the front spar. It is 6" in front of the CG. The fuse. tipped very nose heavy. I think that is good at this point since there are quite a few things that will be behind the CG.


Hopefully I can balance the plane by shifting things in the plane to spare adding lead. But we will see.


I bolted the dummy turkey feathers on the back


I also bolted thee nose on and installed the landing gear.


I made a paper template of the back of the fuse. I will start stacking some blocks of urethane foam to create the fairings on the back of the fuse.

Thanks all for the words of encouragement... Here is a picture of the plane all put together at our club meeting tonight. I was pleased to learn the plane assembled with the engine installed in the tail it balances very close to on the money. It sits on the gear nice with the CG in front of the mains very close to where it should be. Everything left to go in the plane will install through the top hatch on or close to the CG. The second picture is of Vladimir next to the plane. He is the man to credit for making the beautiful landing gear for the Vigilante.

I have a plumbing question. I was thinking about using two 100oz. Dubro tanks for fuel. There are two ways to plumb them. The first would be to have two pick up lines teed to the pump. The second would have one pick up line and the other tank feeding the pick up tank. What has been peoples experience and what are the pros and cons.

Congrats Joe for the Vigilante!.

Regarding your question, you must know parallel plumbing the fuel tanks has a greater risk of feeding air to the turbine and instantly killing it. On the other hand, series plumbing them reduces this risk although you may have troubles with weight distribution as fuel is used.

If it is the case, best solution should parallel connect both main tanks to a smaller feeder or UAT one which will connect to the turbine pump.

I wish you the greatest success when you go for maidening your Vigilante!.

Best Regards.
