Some facts on the ARC Pitts....

Modelbau used to make them for sale via distributors like Desert Aircraft.....if the one I have is an example of the work they did I can't believe they're not still being sold. I believe that the build threads on this and other Modelbau kits list build time frames of hundreds of hours.

So that work doesn't come cheap......not even close to what the Chinese can make ARF's for.

Of course if one is buying the ARC it's likely to be for "scale" purposes, versus going out and flying everyday with a 'down and dirty' ARF

Yo   Won't flame the crrc, but Ive had very good luck with the dle engins and they have a 60cc twin that should be a good engin.

RE: Andy Sheber Pitts s1s
 

gw, the DLE 60cc twin is 3/4 inch too wide. I would have preffered it but don't want the associated holes. I have cut the saddle area pieces and added to the mock up. Everything looks right and measures out right so I'm going to stop here and pull it apart and start glueing.

RE: Andy Sheber Pitts s1s
 

I'm sure most here know's what the one problem is with useing a quality epoxy such as System 3's. And for those that don't,

"The wait!"

RE: Andy Sheber Pitts s1s
 

Robert,
I have been using T-88 structural epoxy on my last few builds and I really like the stuff. It does take a bit longer to cure than hobby epoxies but it seems to penetrate the wood better and does not get brittle like the hobby epoxy. The stuff is FAA approved for use on wooden aircraft so I figured it is good enough for my models.
Later!!
Anthony

RE: Andy Sheber Pitts s1s
 

I use hysol instead of epoxy. Like it much better. $$$$$ but worth it to me.

RE: Andy Sheber Pitts s1s
 

Anthony,
If you like the T-88 you have got to try the GelMajik. Wayne glad you like the Hysol. I used it in construction and for this hobby I think it is overkill. But then again so is the system3 stuff. I do know you can glue two cinder blocks with the Hysol and it "will not" come apart. I used it mainly joining new work to existing. Good stuff!

Hey Acerc
This was a little issue I ran into. I cut the firewall and the bulkhead behind it perfectly to the plans. Checked and double checked it to the plans. When I went to fit the cowl, the cowl was too small in diameter. Might be because I sheeted the front half of the fuse with 1/8 balsa. Ended up having to split the bottom of the cowl to make it fit.
Just a heads up.

RE: Andy Sheber Pitts s1s
 

I'll check on that before I cut the firewall. Thanks!

Checked on it, it fits. Wheww http://www.rcuniverse.com/forum/js/f.../thumbs_up.gif

RE: Andy Sheber Pitts s1s
 

Hi robert, did you cut the ply wing seats as a pair or on their own ?

I cant believe the speed your building at......Top job !

RE: Andy Sheber Pitts s1s
 

I cut them as a pair!

Enjoying watching on of my favorite planes being built. I loved it since I was a teenager.

But then my last name is Pitts. So what would you expect? My wife wants me to build a Pitts, but I have not yet found the right plans. Size is an issue. No bigger than .90c 2 stroke glow. I really like the S2S.

Keep up the good work. I will watch and drool.

Ken

RE: Andy Sheber Pitts s1s
 

Mine fit too before sheeting the front of the fuse. So not really sure what went wrong. No matter, it fits now.

RE: Andy Sheber Pitts s1s
 

I had a Sheber Pitts with a Sachs 4.2 and it was a bit marginal on performance and a CRRC 55cc twin maybe has the power of a Sachs 3.2, so I would rethink the powerplant. I ended up putting a brison 104cc twin and it was just right

RE: Andy Sheber Pitts s1s
 

I kinda figure it like this. I have a 1/5 scale Waco at 18lbs flying with a 26cc. Can't imagine the 55cc in it. The pitts is basically the same dimention's and will, hopefully, only be a couple 2-4 lbs heavier. I also have an Ultimate with the same basic frame sizes with a 55cc and it's a bullit. So I put all that together with my flyin style and what, I believe it will be good. Well see or I'll see.

RE: Andy Sheber Pitts s1s
 

I'm going with a GT-80, mostly because I already have one sitting on the shelf.

RE: Andy Sheber Pitts s1s
 

wayne d,
Is that the 80" 1/3 scale Pitts S-2 from Sheber plans I see in the pictures you posted?
Back in the late 70's, my friend and I built two of them. I did wings and stabs and he built fuses. Fred Wallman, a machinist and owner of Annco servos, cut down two 80cc Olympic chain saw engines and modified them to be airframe power plants for 24-10 props. Both Pitts S-2's came out very nice but heavy, somewhere in the 35 pound area. The Olympic engine weighed 8-9 pounds with electronics and the bare fuse with no covering weighed 9 pounds. With the 80cc, it flew OK but was not a ball of fire. Took my Pitts S-2 to Ida Grove in the early 80's and was told I couldn't fly because the engine in my plane was too big! They did let me fly, however. I sold my Pitts in the late 80's.
Recently my friend's S-2 showed up and was given to me to restore. It is now bare bones and will be ready for new covering after I lighten things up a bit. The engine will be a DLE 111 with a 27-10 prop which will be a couple of pounds lighter, so some tail weight will have to be removed. Servos will digital Hitecs.
Currently, I am gathering parts and supplies for the restoration/rebuild while building a new workshop after my recent relocation. When the shop is useable, I will get into the project to hopefully be in the air by this summer.
Would love to share pictures and progress as we go along on the build.

RE: Andy Sheber Pitts s1s
 

Dont feel bad about splitting the cowl. If you put a angle valve Lycoming 200 hp in a S1 Pitts you have to split the cowl as it is designed for the 180 HP engine, so your scale!

RE: Andy Sheber Pitts s1s
 

Actually have a Seber Pitts scratch from plans airframe I picked up a few years ago. It had a 3W100 on it for power and likely needed all of it

RE: Andy Sheber Pitts s1s
 

It's coming along. I got the base and formers in yesterday. After a day of flyin, well half day, glued in the saddle area and the rear tail support. No, I'm not fast, but I get there!

What you're not taking into account is, the Waco and Ultimate are probably twice as forgiving as any Pitts, The Sheber Pitts is old school building, lots of wood plenty of ply, if you can eliminate a lot of weight in your building, you may stand a chance of the 55cc flying it safely. Members here that have been commenting are people that had or have this same airplane, listen to what they are saying about thier choice of power, DLE 111, Brison 104, GT 80, the GT 80 alone is easily twice the powerplant of your CRRC 55

Yes it is.
