I will try to get video later today.

Mike it would be great if you can compare the flight performance of the 32" with the 32 Edge and Yak, and the 42" version with the 42 Edge. Shorter tail moment holds promise and caution at the same time

I had an EPP plane that had a short tail and I was not particularly fond of it, moved around too much in 3D and needed more input than the rest to stay where it should. I always considered it for advanced pilots only. It was harder to fly but on the other hand could spin, tumble and generally do the chaotic style maneuvers very quickly and tightly. It would snap like no other EPP plane I had, more like a balsa plane.

Both sizes of Sbach seem to have real good authority in all directions. The 32" will rudder turn practically at the wing tip. The 42" makes a wider turn.
To compare the three planes:

Yak-slower and the flight is more deliberate. Better for beginner and learning acro.

Edge-more crisp/snappy response will do more than the Yak. Can do very abrupt pitch manuvers like the wall. Best in knife edge. Fast.

Sbach-less snappy in pitch than the Edge but very manuverable. Fast. I cannot wait to get it in the hands of a good pilot and let them wring it out. It does not seem to be unstable as the strait lines are good. It is just taking some getting used to how much authority the tail has. It is easy to over control. I feel it is better in knife edge than the Yak but not as good as the edge. It is good in hover if you do not over control it.

I cannot say that I like one better that the other as they all fly good but in different ways. Luck for me I have one of each!

It would be interesting to do a short coupled Edge as I think it would be the most extreme of all of these but I do not want to do a non scale plane. Anyone know of a short coupled plane with a strait leading edge? I might compare the T version to the other versions.

Thanks for the feedback. I think I am going for your Edge 32 when my Yak throws the towel.
When it comes to looks, as long as it looks more or less like the original airplane its fine, longer here, shorter there, not really an issue. Performance first. If it gets better flight performance, go for it. I saw in some other designs that people move the canopy forward for example, I am guessing for more neutral KE.

Ordered a 42" in red/black. Hope to get this going soon.
Thanks for putting these kits together.

What size carbon rods are you guys using for the wing and elevator for the 32" plans that are posted in this thread?

And are they rods or tubes?

I prefer a 4mm tube 24" long.

Hi arsenic0,

Since the first Sbach I built was constructed using 4.5mm foam, I used 3mm carbon tube. The one in the wing is 26" long, and the one in the elevator is as long as the trailing edge of the horizontal stabilizer.

For the second one I just finished building, I used the same exact tubes pulled out of plane #1, even though now I'm using 6mm foam. (For this one, I actually substituted a wooden dowel for the elevator rod; a bamboo skewer will work also)

Feel free to post updates if you're building an Sbach.

-Vincent

Ok thanks, and thanks Motorhead, but those 42" go together much differently it looks like than the plans that are posted here.

The 42" link was just an FYI for everyone. The 32" is different.

I keep forgetting to ask, where is the cg on the SBach. I got mine yesterday and I will be setting it up tonight. Thanks. Everything is the usual quality, great kit. Hope I can fly this week, looks like rain so who knows.

Oddly enough I have both my 32" and 42" at the spar which is 3" from the leading edge at the root. I am still playing with the CG a little but it should be real close.

Just for grins, do a Slick.. I'd wager you'd have a strong following on that one..

That's the only plane that I fly that just does things "normal" planes can't.
