Well I have decided to go with a YS F-91 AC engine, Futaba S3151 servos and a 2100 mAh LiFe battery. I may still change my mind before I start, but I am gathering the additional items already. For color I was thinking orange primary, white secondary and trim with silver. With that said nothing is set in stone.

When I start on the build I will try to do a build thread over in the "Kit Building" section, but I will place a link here.

Was flying my tiger 60 with a Saito 91 for three years and learnt alote.the more I pushed myself the better and smoother my maneuvers progressed. am now down to my tiger 2 I just about have ready,i totalled the fuselage and managed to trash the wing as well , the motor made it out ok, awesome plane fly it fast and rock those Cuban 8's at full throttle and see how graceful the tiger is ,,

I was going with the YS F-91 AC, but I just purchased a lightly used Saito 91 from the local hobby store. Now looking at the drawing I do not see anyway to meet the 5mm above the centerline of the fuel tank, so I would be interested to hear what you did about the placement of your fuel tank. Anyone else please feel free to jump in with an answer.

You don't want retracts they are a pain in the you know what. They will not retract into a stock wing without some ugly mods. and the nose gear will not retract all the way up. It does make a very nice tail dragger, mine has a DLE 20cc gas engine and custom cowl but there was a lot of changes made to the whole plane, it is a Tiger in the air and one for the pilot, gets lots of looks.

First off that is one nice looking plane. As far as the retracts go the deluxe kit came with robart retracts and additional parts and modifications. There is a guy at our field that has one that performs flawless and was in fact my inspiration, but he was not the builder. The added instruction booklet is included with the kit with the changes to the model for the retract installation. I hope this all works out.

Mustang,
The Saito 91 I used was installed on a hangar 9 one piece motor mount,i centered the motor on the firewall per the prints and I left the fuel tank as is ,the location of the fuel tank being so close really didn't have any affect a.give it a shot ,also look at my gallery with a picture of the way the motor was mounted and maybe you can get a better idea,

I have decided to put an OS 95 ax in my new Tiger . It isn't any heavier than my OS 75 that I have in my current Tiger but it has a lot more power . I had already ordered it before I realized that it wasn't any heavier than my OS75 . I was actually looking for something with a bit more weight because Tigers usually come out tail heavy and I was hoping to lose the lead in the nose . I am making it a tail dragger and increasing the size of the tail feathers by about 3/4" . I will push the engine out a bit and make a built on cowl .

MTC YMMV but I've flown them both with the same ST 91.

I have been thinking about my upcoming build and I was thinking of using two pieces of 1/8" diameter carbon fiber tubing through the frame members aft of the wing to the last frame member. One each located on either side of the lower portion of the frame members.

The original Sky Tiger, was an Eagle 63 turned upside down to be a low wing. So essentially it was a low wing trainer. I built one in 1985. With a 63" wing, it is a .60 sized airplane. The New Tiger 2 models are different, and that is when they made them a .45 and a .60 size. The .60 deluxe had a retract version. These aircraft came long after Carl had passed. Goldberg did have plastic resin retractable gear sets long ago. They were mechanical, I have no personal experience with them.
While adding retracts would add some weight, I find it hard to believe the extra weight would effect the already super low wing loading of the Tiger series. I wonder what exactly that little extra weight did to the performance? It had to land faster? Retracts are a tricky beast, but in a setup like this, they can be very user friendly. Robart makes a set that are spring down, so if you lose air, they come down automatically. The only issues I have had with this set of retracts is a servo issue with the valve. Nothing to do with the retracts themselves. I personally do not think retracts are worth it on a sport model such as this, but they can be fun to play with, and good practice for that warbird you always wanted!

One thing to remember about retracts, when they are retracted, do not allow any part of the wheel or strut to make contact with any part of the wing. The pressure put on the strut or wheel (even the slightest) will not allow it to unlock. I have learned this the hard way! Retracts have a tendency to fail up, exactly where you do not want them to! This is more of an issue with air up/down systems. But it is important to know.

The tiger is a great plane to practice mid air pattern moves,it's so docile inverted and rolls nicely,the saito 91 4stroke pulls really nice especially on up lines, I might consider building another but for the mean time I'm going bigger and faster , will always have a tiger on hand.
