Hey Guys,

Well, it's here! The 48 3/4" SBach 342 from RC Factory just cleared customs and will be shipping shortly. It is one of the newest offerings from Twisted Hobby’s, the only US importer of the RC Factory EPP designs . The 342 was designed by Jan Sedlacek and the RCF team. Jan is the current Czech F5D champion and is a long time F3A competitor. The plane is modeled after the RS 352 SBach, German designed aerobatic plane. The 342 is a follow up to the smaller 1m or 39” RCF planes such as the Flash, Yak and the SU-29. The 342 is for Extreme and 3D aerobatics, offers smooth pattern performance and can be an ideal 3D trainer. This one should be fun!

I have been eagerly anticipating its arrival ever since Brad from Twisted Hobby’s asked me if I would do the build thread. I, of course, jumped at the opportunity. I have been a fan of the TH product since day one when Brad developed and started selling the Yedge , Vector, Slick and now the Crack series and the Telinks and RCF product. I think the Yedge came out about 4 years ago now . Time fly’s when you’re flying the best EPP out there.

This thread is going to be a work in progress designed to be informative, enlightening and at times life changing. Ok… so we probably will not enlighten or change anyone’s life but hopefully we can be informative. If anyone has any suggestions or ideas to better the thread, please don’t hesitate to contribute. And remember,….The only dumb question is the one not asked…. (That was in my fortune cookie last night. Sounded good at the time?)

Build Notes: The main fuselage carbon bracing will be the only area of the build where I will be using CA. Although RCF recommends using CA throughout the entire build, we are recommending using CA only on the main fuse carbon bracing and Welders on the rest of the build. We are using CA on the fuselage section because there is very little glue surface for the fuse stiffeners to adhere to the EPP, CA is simply the better choice for this area. CA also dry’s creating a stiffer joint, helping to insure the fuse section remains stiff. We are using and recommending Welders on the remainder of the build. Welders can be purchased at many Lowe’s or TH has it available here: http://www.twistedhobbys.com/Welder-...oz-WELDERS.htm
http://www.twistedhobbys.com/images/...582181393.jpeg

There are numerous techniques for using Welders glue. I will share the method I use but feel free to use whatever method works best for you. When using Welders, I coat both surfaces to be mated, I then join the two pieces and pull them apart several times. I then let them sit apart for a minute or two and sometimes longer for the larger joints such as the wing halves. By doing this, you create an immediate bond when the two pieces are again mated and also, drying time is greatly reduced. Drying time will vary depending on the amount of glue used, size of pieces being glued, environment etc.. But in most cases, you can continue the build within a very short period of time.
[B]Important Build Note:
The motor mount needs to be installed prior to the top fuse section. Installing it after the top is on is very difficult. There is no need for toothpicks or anchoring tabs as mentioned in the instructions. Just Welders it to the surrounding foam.

A definite must have upgrade for the Sbach are the carbon fiber servo extension arms.

It will turn the somewhat tame 3D’r into a 3D animal. I did not need them on the rudder or elevator as I am getting 45 and about 40 degrees throw on those surfaces. The aileron deflection with the standard set-up, although sufficient for sport, pattern and basic 3D, was not sufficient for getting really crazy.
Now I can do some really fast rollers, great snap rolls, fast point rolls etc…. I highly recommend them.

Sub'ed.

Thanks for doing the build thread Gravity.

My stuff is on the way and I'll share my build here as it progresses. Of course with defference to your build since you accepted the task.

Input is welcomed JC. I have enjoyed the 32" and 44" from TH but now have a 47"!! this is going to be great.:)

Can't wait for this. I'm totally getting it after I beat up my crack yak :)

Similar hangars - I had an Extra Slick v1 (buddy talked me out of it), but currently have a v2 Extra Slick (nobody can talk me out of this one), and the Red Scheme Telink SU-29.

I think ths plane is going to be the best of both combined into one awesome package.

Better order soon - they are in limited supply.

I debated on adding this one to my collection, but after having dusted off my 1.0m Sbach and spending a fair amount of time in the air with it the past couple weeks, I was reminded of what a nice flier the Sbach's are, and decided to go for it. Looking forward to all the insite as will be provided by Gravitycheat's Build as well as comments and posts from others here on this thread. Really looking forward to the bigger size of this plane.

He's on RCG so maybe he'll add to this thread.
