Powering the S-Bach 342

Hello all,
I am about to finish of one of these bad-boys and was wondering if the DLE 61 engine would overpower/overweight the 29% scale airframe which weighs VERY little to start with. If this is indeed the case then would the DLE 55 be sufficient for possible 3D flight?
Thanks in advance

Biker,
What do you think your S-Bach will end up weighing flight ready? I have flown an 18lb cap 232 and a 14lb Extra 260 on a DA50 and both aircraft had plenty of power. I am not sure how the DLE55 compares to the DA50 but I would guess that they have similar performance.

Not sure PA, but if I had to guess, I'd say around the 14 lb range once all is said and done...

Biker,
I looked up the DLE55 and 60 and there is a .5lb difference between the two. With this size aircraft and if it is going be in the 16lb range I think that I would go with the DLE55 to save the .5 of weight. I don't think that you will be lacking any power with the 55. It should have enough power for pattern style flying. I don't think that you will have enough power for full on 3D flying with the 55. I don't fly 3D so I look for what gives me good pattern flying performance and helps me keep the weight down.

Ok....I will take a closer look at the two...
Thanks for your input Plane

Biker:
I have this airframe from Slipstream in the 30cc size. I encourage you to take a good hard look at the engine box and beef it up if needed. On my maiden, my DLE30 almost shook the firewall out. It was my first gasser and I was too inexperienced to see that the engine box was not built to withstand the vibration of a of a gas engine.

My Pilot RC 50cc with a DLE-55 on a canister was more than capable of flying 3D in the right hands. Certainly it wouldn't 3D like my 15 lb MSX-R but it acquitted itself quite well.
Also a little weight actually helped it carry energy through maneuvers better than the lighter MSX-R. I wish I had a video of my buddy flying but, but well....he 3D's my night vapor, so I can tell you its more about the pilot than the airframe

Cuda,
I went ahead and took the plunge and picked up the DLE 61, also went with Hi-tech 7955TG servos all around with redundant A123's for power....after taking a look at the DLE, man this is a lotta motor!.....I have begun adding triangle to any and all joints near the motor box and this is after hitting all joints with thin CA..
I do have a question though about the canister issue, I'm not TOTALLY new in the gasser arena, but I'm curious as to why I would need this other than for possible sound ordinances near the area....

I'm going to have to disagree with your assessment as to whether it will fly 3D with a 55.

Hey Biker,
I have that same 50cc Slip Stream SBach 342.
![](https://farm8.staticflickr.com/7321/8723451912_a355a8c7cb.jpg)
I bought it used and it's powered by a DA 50 with a canister. I've modified it extensively - see my web page (http://www.grosbeakrc.ca/aircraft/sb.../sbach342.html) and photos (https://www.flickr.com/photos/rests/...7632541413461/).
Take note that unlike the Pilot RC version the specified CG is almost an inch forward of the wing tube. I have three batteries strapped to the motor box and it still needs lead to balance. That's part of the reason it's heavy at 19.8 lbs.
With the weight and the powerplant it's a good IMAC plane - I don't know if you'd want to 3D it, though. I have no interest in doing so.
