Hey Pattern People...
I just picked up a nice Brio! The deal came with a couple Webra 160s, one new and one used. Both have MC carbs. The Brio is totally set up for the Webra and even has both throttle and mixture servos installed. I am relatively experienced with the OS160FX and the OS140RX and have had good luck with both. On the 160 I run the Jon Lowe set up with the Perry VP 30 pump. Jon's cookbook is pretty fool proof. Can I get some input on the Webra? Anyone have a quick start fool proof method for this motor? Fuels? Oil content? Pipes? Props? Plugs ETC?
Thanks much in advance!
Rick

Rick,
Read the thread about the Syssa gas engine. Buried in the thread is a discussion about running the Webra 160 and proper set-up.

Will,
Do you know which page?
Thanks,

since you have 2 of the 160s they would make great bookends if you convert the plane to electric that way you wouldn't have to worry about how to get them to run. You would just plug it in and fly. Just kidding. Good luck with your new plane. Jim

Rick, I think it is in the SAP 180 (Syssa Performance) thread as opposed to the first one. You can find it I'm sure. Dan

I'll do that if really need nose weight or want to pracitce gliding.......Mark A is Total E now.....

Will,
I did find it and that was what I was looking for. Good simple cookbook info. Thanks Will and thank you Matt! I'm really looking forward to an apples to apples comparison with my OS motors. The Webra looks to be 4.6 oz lighter than my 160FX. Thats a good start...

Does your new Brio look like the photo below? I suspect it does! Assuming that it is, this is from the 2006 AMA NATS. It is a fine flying model built/finished by Dave Guerin.

Quick set-up tips:

1. The throttle/mix servos should be at 90 degrees at mid-throttle and mid throttle curve.
2. Attach fuel tubing to carb while closing mixture arm until air does not come out. This is (0) fuel and may or may not match the factory mark on the carb.
3. Slightly open both throttle/mix and start engine...lots of smoke...rich.
4. Advance the throttle to the next mixuture point (Futaba or JR) and adjust mixture maintaining plenty of smoke (rich). The engine should transition from low to high.
5. Continue through all of the points on your mix curve until engine transitions from low to high.
6. The curve looks like a banana with typically full mixture at high throttle.

The above is generally a one tank of fuel process. If your radio has the option, add a variable mixture slider to adjust the upper part of the mix curve to avoid a very dangerous to the Webra "lean" run.

Props: The photo shows one of Dave Lockhart magic custom (3) blade props. Mike Harrison was puzzled why I did not just run the APC 18" x 10" that he loved on the OS. I never tried it although the pipe may need to be lengthened to smooth out the mid range.

Rusty,
That's it! The plane has a great history! I'll, with some study and guidance, figure the motor out. I have the JR 9303 and believe it has the capability to do what the Webra needs. One of the Webras is used and broken in and I'll get the feel of it and then maybe intall the other one in my son's VF3. The OS160 lacks alittle at the top of big maeuvers at our weight. A diet plan with repaint is on the agenda this winter on the VF3. I got a little heavy and came in at 10-14 with all paint. Wings will be covered and fuse stripped and repainted. I used buterate dope from Randolph, real airplane stuff, and discovered it AIN'T FUELPROOF!!! Imagine the horror!
Well, still livin and still learning...
All advice is greatly appreciated!
Thank you!

Geez, Rick, you're gonna have some great looking airplanes this season!
Barnaby Wainfan invented a term....Gloss Divergence....do descibe an ugly airplane, like an Ugly Stik, built and finished way better than it needed to be. I wonder if there's a term to describe that divergence between plane and pilot?

DaveL322 was kind enough to send a huge amount of great info on the Webra. Where do you get a header and what ES pipe works?MTK says the K&B 1L plugs actually transition better than the higher priced stuff. YS 4stroke plug and OSF are supposed to come from the same factory. I have run them both in my OS160 and 140 and they seem to perform the same. They cost 8 or 9 bucks depending on where you buy them.I just ordered a card of the ILs at 4 bucks ea. Great Deal!

Rick,

The K&B 1Ls work great in the OS stuff too. I actually preferred them in my OS 1.40RXs. They also seem to last forever which is a nice bonus.

In order of hottest first...

K&B 4C
OS-F / YS 4C
K&B 1L

"Heat" can be added to a 2C in a number of ways......higher ambient temp, more compression, more nitro, hotter plug, leaner mixture. Many combinations will work. I always preferred to run the hottest plug and a slightly richer mixture...which keeps the engine temps cooler (more fuel moving through the engine) and exhaust temps lower (quieter). Especially important with the Webra 160MC as with the very thin sleeve and case around the sleeve, it has little tolerance for running hot from a lean mixture.

Regards,

Dave

Would you recommend using the existing pump or going with the VP 30 Perry?
The OS140 also had some people claiming vapor lock.
Is the Webra pump vapor locking or actually being damaged from heat?
RC

DaveL322

I had the best success with the pump out of the backplate to keep it from heatsoaking AFTER a flight. Stock Webra pump or P30 both worked well. I ended up running the P30 simply because it was lighter, and I think the diaphragms in my Webra pumps were damaged from heat (although I do know several different diaphragm materials were used along the way, so maybe the issue I had was solved at some point).

I've never seen what I thought was vapor lock on the 140RX (and that engine has more flights for more pilots in the NE than any other by far).

Regards,

Dave

RC,

No problem, glad to help and send me a note if you run into trouble. One thing I don't think I mentioned (but Rusty's post reminded me), the 160 comes with the in-flight mixture carb and I did not use that one. I used the trusty and true standard manual adjust. The recipe I gave deals with that type of carb only. The other carb requires another servo and more complexity but I know Dave Lockhart had his running very nicely. Hopefully Dave will chime in with his set-up on two servos

Rick good luck with that Brio. It's one of the best looking Brios I've ever seen and Rusty flew it well. Too bad Hartwig didn't have the time to use it because he was an excellent stick.
I had a Webra for a year and have to admit it had me stumped at times. I had a lot of good advise from Dave Lockhart and Tony Frak on getting it to run. Most of the time it was pretty nice. The mixture control was actually a lot of fun to set up. It's a very nice feature. Webra Germany sponsored me when I was a kid and I've always had an affection for their stuff.
I hope it goes well for you and your son this season. Mike Mueller

Matt. What carb did you use? and are there any other options?
RC

MTK

The Twin Needle (TN). It is very simple

The MC in-flight mixture control offers more control. I just didn't get around to trying it
