I built mine when they first came out and I'm still flying it. I got one of the first kits in the midwest in late January of the year it came out, 2006? I forget the year exactly. I built mine exactly as per instructions and used all the items in the kit with the exception of the push rod. It was a bit too short. I powered it with an OS LA.25 just as suggested in the instructions. I did this so that if anyone came into the hobby shop I work part time at and asked if it could be built and fly as per instructions without modifications, I could tell them with out hesitation, yes, absolutely. The tank was the first item to wear out, but not after quite a while. The hardware, nuts, bolts and such, is not the best quality, but useable. I used the same line length, handle spacing and engine set up Mike called out in the instructions. I got it assembled just in time for our Ice-O-Lated winter contest and put three trim flights on it before the contest. The result was a second place in profile that day. I flew it with the LA.25 for quite a while, then switched to the FP-25 just to get some experience with that engine. I think the FP had just a tiny bit more power, and ran both engines on 15% nitro fuel. Even with as well as it flew with the .25 engines, they were on the ragged edge for useable power. They were pretty much right at the peak of what they could put out for the 43 or 45 ounce air frame. Another local guy, John Garrett, put one together and powered his with an OS.32 and i was impressed with that set up. I had one in my engine stash, and when it became necessary to recover the whole airplane, I re-engined it with my Randy Smith OS.32. I don't know how many flights it had by that time, as I flew it A LOT! The covering was just coming apart. The clear top side of teh covering was separating from the colored portion. SIG no longer carries the same color orange, so i went with MonoKote. Do a search on the forum here and I went into the recover job in detail and what it took to get all the accumulated oil out of the balsa and ply. The recover went well, and even though the .32 was a larger engine with ball bearings, I still had to add some weight back to the nose after digging out all the lead shot I had epoxied in the nose for balance. And the finished model only picked up a half ounce or so. I love the engine, and have found a few more that are stashed away. I also have a Black Night Saito .30 in the heard and may follow Keith's lead and try a four stroke on the next one. I also have a couple more SIG P-Force kits stashed also, plus a couple of Mikey's short kits and plans. The next one may be from Mike's kit and I'll build it like the ARF kits with the leading edge sheeting. Just my 2 cents worth on my experience with what I think was the best ARF to come out on the market, and SIG should consider another run or two of them.
Type at you later,
