Sig Tri-Star
 

Has anyone built and or flown one of these?
I am putting the final touches on one to be powered by an ASP .09
Any thoughts?

Is yours the revised kit? If not phone Sig and see if they have any of the heavier gear. The light gear drags badly. As it is mine (MDS 18 powered) with the heavier gear and slightly larger foam wheels takes a pretty long time to rotate on a paved runway. Grass, not likely.

As far as mods go, besides the revised gear I added a shim for upthrust to help make rotation a bit easier. I also fully sheeted the wing, which makes for a slightly heavier model, but also allowed me to use monokote instead of low heat film.

Its an interesting model to fly. It rolls nicely, but is not particularly aerobatic because of the inherent stability of the canard design. Dead sticks (MDS, remember!) are pretty gentle and predictable with no nasty stall characteristics. Its also real easy to get disoriented with it if it gets far out, but as far as I'm concerned its uniqueness makes it well worth the effort.

When I made this complaint about a delta I had built a fellow club member who is a retired aerospace engineer pointed out that long takeoff runs are characteristic of full scale deltas and canards.

Flew the tri Star
after breaking two props from rock damage
we decided to handlaunch
my helper asked all kinds of question about how ( at what angle) I wanted it launched, we fire up the AP .09 with prop # 3 and he throws it at a 45 degree angle . luckly hard enough to get it high up so I had time to push the nose over. The rest of the flight went without trouble.
flys like a trainer
needs more power, but I think I'll leave it where its at. After all to get more power means adding more wieght, to both ends!

Thanks for your input

plans
 

Does the Tri-Star come with full plans... and would anybody like to trade a copy of them?

I just flew mine for the first time. It did take a long time to take off. I power mine with an OS 15. I have been considering putting an OS 25 on it mainly because I find it easier to find pusher props that the 25 can turn. Once off the ground, mine flew wonderfully. I was concerned about landing but it had to have the most gentile landing characteristics of any plane I have flown except my very first trainer (a thunder tiger 40 trainer). I do have an extra set of plans, I am not too sure if they are what you would consider complete. They do have scale drawings of all wooden parts but I am not sure if the wing diagram gives enough for a set to be made, I have not had enough practice is scratch building to know.
Here is a picture of my plane, if it does not show up, you can see it on my website along with taxi and run-up pictures. I hope to get flying pictures soon.
