Well here's the kicker, first few minutes in the air I knew something was wrong as I could see there was a ton of wing flex and brought her down, but instead of looking for the spar, I just tightened the wing screws more and put her back up in the air ... and down she came.


I'm not thinking it was very repairable. Note to self - wingspars are not there for looks. I guess the fact that you can't see them is kind of a give away, eh?

I got lucky, even though it smacked hard, only the cowl shattered, the rest was easy to repair with glue and no need for boiling water as none of the foam smooshed! The nose cone and motor firewall foam took the brunt of the damage, as well as the landing gear ripping off and of coz the cowl shattered.

Less than an hour of gorilla gluing the firewall, CA gluing the SFG part, elevator part and the clean split fuze and now just waiting for some cowls to come in.

I will FOREVER never store my planes without spar installed .... NEVER

Here's the vid, though it's still being edited.

Ive been flying my sbach for a few days now, and will have to replace the rudder servo,
its stripped from a not so great landing.

I have my cg at the 80mm point and when flying it seems to want to drop the nose in the turns badly.
cant seem to trim elevator out for level flight, maybe elevator servo problem. (not touchy)
inverted flying is almost hands off level.
tried to pull into a hover but she wants to pull hard right (nose).
so anyway it flys ok, just some servo and trim issues to sort out.

You will do well to replace both of those servos. Once I replaced mine my s Bach flies like it's on rails. It hovers very very well and is a joy to fly. Beware if you replace your servos you may find that the arms on the new ones are not as long as the arms on the stock ones So you will have to move your push rods up on the control horns. At this point I couldn't be more pleased with this airplane. I did notice that I have to keep my rudder trimmed to the right to offset the torque.

Man, I'm loving this thing. The more I fly it, the more I like it. I got a few passable hovers this weekend and decided to bite the bullet and fly on high rates - HOLY COW. Apparently I also forgot to program expo into my high rate settings What a blast.

Unfortunately, my landing gear mod failed me. The basswood did fine, but the Epoxy didn't hold the LG bracket well enough and what would have otherwise been a nice landing and roll out stopped a bit short with the wheels pointing up towards the cockpit. I think four small screws and a little less brittle epoxy mix will seal the deal.

Did another video from the (WWII) Pilot's perspective. I'll upload for your tummy roiling pleasure in a couple days.

Flew mine again this weekend. Got the LG screwed into the basswood and no problems with LG collapses now. Getting better at hovering it, but I think my CG is way to far forward. I barely have the battery on the stock velcro as is - I think I'm going to need to build a strap. where are the rest of you putting your batt?

What Hobby King one? Hobby King has a ton of different Sbachs. You talking about the 54" EPO one? No, that's not the same as the Dynam 49" one. Is the HK one you got a 49" plane?

No, that's not the same as the Sbach. It sounds nice, but I'm always suspect of HK's plane's flying characteristics. 15/7 prop sounds a little steep for an 800kv motor.

I'm ready to pull the trigger on one. So are the horns still an issue?

Yes, though they do screw in now and aren't just glued in. They are still brittle and I ended up having to replace both of the rear control surface horns with new ones.

The LG is still an issue - see the mod I did, it has held great since. do it early and you'll have fewer repairs/scars later. The servos - rudder/elevator are also likely to strip on you, but you can get a few flights out of them so you can take your chances if you want (I did).

Once you get that straightened out, it's a fantastic plane.
