I've been flying my 4*60 ARF with an MDS .78 and happy with it. I did come across most of the "problems" Jim listed, though many of them are simply petty annoyances having more to do with quality control than serious structural concerns.

1. I taped the string to the servo extension to form a pointed end - better for negotiating the tight turns. Sig could have easily engineered this better.

2. I use two (2) 12" extensions for each of the ailerons. One attached to the servo, one to the RX, which is burried in foam. This way, I can attach the aileron servo leads with the wing and fuselage sitting firmly on the ground/bench.

3. I had to enlarge one of the wing hold down bolt holes, too. I did this before gluing the ply plate, so the end result is pretty clean.

4. The tank orientation is okay. The upturned vent line just needed to be a little longer. As per my usual practice, the fuel tank is siliconed in place solid. Foam padding often cause more vibration-induced fuel sloshing than it helps.

5. I used GP adjustable mounts instead. I am usually a tightwad about ARF hardware and use most of the OEM bits, but this one is well worth the expense.

6. One of the fields I fly at is grass and the 4*60 has a tendency to nose over on thick St. Augustine grass, even with the landing gear set up for added forward rake. I would suggest a taller tailwheel bracket for flying off concrete. I find that getting the airplane to sit on the ground with a more level attitude helps with landing bounces more so than main gear position relative to CG.

7. Poor fit of wing LE to fuselage cutout - YES. TE is not too bad.

8. I suspect the fiberglass tape is meant for the wing joint. I peeled back the Ultracote and fiberglass the center joint with a wider piece of FG cloth. Curiously, the factory had pre-install FG over and wrap-around the root rib. I like FG'ing wing joints whenever practical.

9. My landing gear came with wheels installed, too, though I ended up dissassebling them to replace with larger wheels anyways.

10. Mine came with some minor damage on the left cowl cheek, so I added FG to the cowl cheeks at the same time I did the wing joint. No biggie.

11. I ended up using dual elevator servos, since I forgot to install the wire "U" joiner when I glued on the horizontal stab. DOHHH!!! No matter, works better with two servos anyhow. Consequently, I had to go with pull-pull rudder, since both the tubes are used up for elevator servos.

Overall, I would say the $199 (now increased to $209) price tag is too much compared to other ARFs you can buy at this price. For example, I am building a couple of 72" aerobats made by GSP and they are better built and much better values for $199. I ended up paying much less for my 4*60 because it came damaged, so it was a fair deal for me. Personally, I wouldn't pay $200 for it.
