Troy,

On the OS 140 RX check here: http://www.rcpattern.com/2cycle.htm

Hyde mount is been proved for years so you should be fine. There are other like the Budd mount. However, I don't know the new firm type but I will bet that is good product.

On the servos I don't know FMA servos. I have been using JR 9411SA on ailerons and JR8411SA in the elevator and rudder with very good results for years. If you are going to use the servos for a pattern plane I suggest that you do more research of the FMA servos. I haven't seen anyone using those for pattern.

You can do more research using this web site: www.nsrca.org Check the links.

Good luck,

Vicente

Hi Troy, regarding FMA servos, I bought 3 of their new digital servos that are manually adjustable and can run on 4 - 12 volts. They never stopped hunting and buzzing in my set up so I finally replaced them with standard Futabas and had no more trouble.

Hi Troy,

I've have used the OS 140Rx now for the past 4 years, for the pipe I've used both the T. Prossor pipe (bought through Model Sports) and the Hatori #900 pipe, both worked the same, you can pick up the Hatori pipe through Singapore Hobbies at a good price if you want to order from oversea's, if not I would buy the Prossor pipe in Aus, better price than the OS / Hatori pipe bought here in Aus.

I'm also using the Hyde OS140 ARA engine mount at the moment, great mount very light. Would use again.

As for servo's I agree with last two replies as to stick with my choice of Futuba servos but JR are just as good and not too try those other servos, the extra price is worth it in the long run.

I use a greves pipe with great success. Lightweight with great power. Although a little long..

RE: OS 140 RX questions
 

Hi
Who sells Greve pipe please ?
Do you know dealers in Europe ?
I think Greve is German.
Thanks.

RE: OS 140 RX questions
 

I flew OS 1.40RX the last 4 years. Very hard to beat the ES pipe, macs header setup. Very quiet. 86db at the NATS last year. Another great trick is to run K&B 1L plugs. I would get several hundred runs on a single plus with 15% Cool Power. I changed plugs the week before the NATS the last 2 years, just to say I changed plugs. My dad is still running the plug I took out last year in his sport plane. Very affordable too. That setup has great transition, great idle, nice top end 8100RPM on a 17X12. I left the header the full length with about a 1/4" gap between the header and pipe and just flew. Very low maintenance setup.

Arch,
Which ES pipe??

RE: OS 140 RX questions
 

Not trying to argue on this as I know the es is a great pipe. But every es pipe I have heard is louder than my setup. Especially on uplines. And I believe the greves puts out more power from what I have read.
Also check out the aeroslave pipe. A little louder, lighter, and more power.

And I can't find anyone who sells the os greves pipe that piedmont carried. Now you have to buy the webra greves pipe.
Same pipe I have on my OS now..

RE: OS 140 RX questions
 

Seems I went through this one the other day......and fiddling with another brand cost me my prototype Black Magic. Lean top end, spitting rich bottm, lengthened the pipe and did everything I was "supposed to", and still now I have a broken airplane because I didn't go with what has always ALWAYS worked for me flawlessly for 5 years straight. that's what I always seem to get when I listen to the "experts".

ES 2C140M80. that's the best, plug, play and forget about it. Anything else, and prepare for some fiddling, lengthening, propping, general tinkering...and for everyone ELSE in the world to tell you they never do any of that..... ;) (or you must be doing something wrong).

That's my 2 cents, over and outie.

What pipe did ya go with Mike?
And what pipe did you have?
What was the problem with the new pipe?
Sorry to hear about your plane.
I'd be glad to measure my pipe header and engine combo, which is flawless and very easy to run for anyone.

Hey Everyone

I just wanted an easy answer !!!! LOL

Thanks

Troy

RE: OS 140 RX questions
 

I'd rather not say, so take it with a grain of salt. If I say which brand bit me, this thread will be dragged into a Ford vs Chevy vs you must have done something wrong fiasco. I have learned my lesson with that.

I'm just going to say I'll never use anything but the ES 2C140M80 behind an OS140 and stock header again. If brand x or y or z works for whoever else then that's great! But not for me. I'm sticking with what always has worked for me. Scratch built pattern planes are too much work and time and cash to mess around with an unknown factor.

The plane is not totalled, but it's definitely injured. I'll fix it if I ever get any spare time, right now I have 2 brand new ones about a week from test flying, so I'll just gut the original.

You got one. get the ES [8D]

RE: OS 140 RX questions
 

Thanks Mike

I will order one today, do they come from central hobbies ???



Thanks

Troy

RE: OS 140 RX questions
 

Mike,
You obviuosly know what you are doing and are competant enough. Not questioning you. I wouldn't argue with you if it was the greves. No big deal. I have seen many people that didn't set up the 140rx header with the correct length for different pipes. It's not a problem with the pipes. It's a setup problem. Hard to blame the pipe. Even though the change in pipe cost you a plane. But the pipe itself works perfect when setup the way I have it. Ask anyone in district 7.

Es pipes are great and you will be happy with one Troy.
Good luck to ya..
Chris

RE: OS 140 RX questions
 

Hi Patternflyer

Thanks very much for the information

Thanks

Troy :D

RE: OS 140 RX questions
 

Yeah just get it from Central Troy.

Chris, I know what you mean, it's really the same as some people having flawless performance from a YS when others can't get through a half a tank to save thier lives. Not sure if it's set up, wierd batches, climate, odd planet alignment, or what....but there's something there. When it comes to power plants, every person has to seek out what they can make perform reliably for them and stay with it. it's when you start experimenting is when you take chances. nothing wrong with that, that's how progress is made. but every time I do it with engines, I get bit.

I simply prefer what works right off the table for me, every time, no suprises. I'm really not that "brand loyal" except for a few things. I absolutely like Hyde mounts, OS 140s, ES pipes, JR digital servos, MK hardware, PBG tubes......everything else is fair game for swapping around. And that's a LOT of stuff....

Mike

What do you think of these new hyde mounts as the picture at the top of this post

Thanks


Troy

RE: OS 140 RX questions
 

I don't know, it looks promising....but it's brand new, I'd have to see one in use before I'd give any opinion.

-Mike

RE: OS 140 RX questions
 

Oh well

I might be the gunie pig then, I think I will order one to try it


Thanks


Troy

RE: OS 140 RX questions
 

Hey Mike. Have you seen one of the new aeroslave carbon pipes run yet? They are super light and produce alot of power. Just out of curiousity..
All of the glow problems I have had in the past was ys related. No problems on my o.s setup unless I go to a higher altitude. But I think my pump is heatsoaking. Had to run it on coolpower 30%. Wouldn't run on my Magnum #1. Great motor though.
But I should test fly my new Electric Eclipse next week hopefully (depending on work). No more glow problems thank god. lol.

Maybe I'll meet ya at the Nats if your there..
Chris

RE: OS 140 RX questions
 

I will positively most definitely be at the Nats [8D]

See ya there!
