I got these, Power Servo XL-17MB on recommendation from someone in the Sbach thread. All I can say is ... WOW they are FAST with great torque.

Site says Stall Torque is ≧2.0kgf.cm (49.0 oz/in.), which is a mistake/typo so I emailed them which is correct, 2.0kgf.cm about 29oz/in or the 49oz.

No answer yet, but I have to admit these really do have some torque, so I'm leaning more towards the 49oz. Only have a couple dozen flights on em though, Seattle weather SUCKS this spring season.

Wow, those look like nice servos for only $7!

If I hadn't already ordered the Hitecs I would have tried those...

That's great news about that servo. I'm just about to put that in mine to replace the elevator servo that stripped and was a little worried about it. I also have the 9g version that I'm flying in my 48" EPP Extra with no issues yet Really is an amazing price for what you get.

No it doesn't, but Hobby-Lobby (main headquarters / warehouse) is local to me and I get a small discount for being a member of one of the local clubs. I buy my parts from the dudes you see on their product boxes and website.

Got my HS-82MGs and two extensions. I'll save the 17g Detrums for some scratchbuild fun. Those 7 dollar servos look like a great deal. I'll have to remember them for another time.

I was FINALLY able to have an incident free flight and actually land the thing on my 3rd Flight.

First 2 flights I had a lvc during inverted flat spin and prop adapter flew off on the 2nd Just started to read this thread and will double check my motor mount and motor screws as well.

Use Threadlock on these screws!

It may have been mentioned in this thread before but you definitely want to apply thread lock to the screws that secure the upper wing to the fuselage struts.
I was checking my plane over after the 4th flight and noticed I was missing 2 of them .
Off to Home Depot I go to see if they stock this size screw and nut.

I really, Really, REALLY do not like HATE collet style prop adapters, especially on a 3D plane that's going to spend some time hanging from it. They are a pain to get straight and very easy to bend, strip or break from overtightening. If you use lock-tite, it may not come off without damaging the cowl. There seems to be no standard size to them. Every manufacturer makes theirs a different length or uses a different length compression sleeve so you might have a large gap between your spinner and cowl or they might rub.

X-style motor mounts and bolt-on prop shafts should be an option or even the standard for every motor over 350 watts. The number of stories you hear about props flying off in mid flight because of a collet style adapter is just crazy and they add yet another element of danger for people around them. I wish collets would go away.

The 5mm e-flite one I now have on mine seems to be ok so far though.

That's the one I'm using too on my Pitts and Sbach. Out of the four that I tried (two included with said planes, one other I had, and the E-flite I bought just for it) it was the only one that didn't wobble.

The RED ARF seems to be in stock as of this post.

http://www.nitroplanes.com/60a-dy894...s-red-arf.html

Though I've ordered in the past with something in stock when I checked out only to be saddened later when I get am email saying, "You suck, you no order fast enough ... go fly a kite."
