I received my VF 66 Extra 300S a few weeks ago. I also am putting in a Saito FA-100. I think the Saito 100 should be enough powder to hang it. I thought of the YS 110, but too hard to get and pricy. Plus, the pressured tank could be and issue. I am almost finished with building it.

1. ) I would recommend using Robart Pin-Stlye Hinges instead of the CA hinges. I used 4 hinges in each aileron, 3 hinges in each elevator, and 3 in the rudder. I also sealed the topside of the hinge gap with hinge tape to avoid any potential flutter. I wrote a separate post on the hinge gap issue today. I had a 1/16" gap.

2.) To install the belly pan use four 4-40 brass inserts instead of the 4 tiny wood screws that are provided.

3.) I replaced the wheel axle with a Dubro 5/32" axle.

4.) Use plastic oversided washers for the two 1/4 -20 wing bolts, so it doesn't dent the wing when screwing them in.

5.) I am thinking of using 4-40 aileron rods instead.

6.) I fuel proofed the fuel compartment with fuel proof paint incase of a fuel tank leak.

7.) I am probably going to go with DuBro control horns.

8.) I beefed up the tail and stabilizer with 90 deg balsa stock in the inside corners. I plan on doing some high stress snap rolls.

Let me know how it goes!
