OS 60 FP

With all the popularity of the smaller FP engines I was wondering if anyone has tried the 60?

Bill

This has been brought up before and the general conclusion is it's a Boat anchor. Do a search on "FP 60"

Well, excuse me.

>Well, excuse me.

Bob was just relaying an opinion from a very recent thread (like, maybe two days ago).

I know nothing about it, but most people building airplanes large enough to need an engine like a 60FP probably prefer to use one of the many tuned-pipe 40-65 engines that are currntly available, or a 4-stroke of similar capabilities.

For my on money, if I go to the effort of building something like an Impact, Trivial Pursuit,, SV-11 or similar, I would want to power it with something that's a known performer. There are half-a-dozen motors that will work with no known development required - and that all fit OS 40/46VF mounts and thus can be freely interchanged.

I wouldn't discourage you from development of the engine, but bear in mind it frequently takes experts years to sort out unknown quantity engines to the point that you can even tell whether it was all a waste of time.

I certainly don't think the weight is an issue. If it runs well but weighs 4 oz more, that really doesn't matter all that much. Problem is, it's going to take 2 years of experiementation to figure out if it runs well, ro can be made to run well.

I seem to recall a NATs and a Team slot going to someone running an engine with the power < or = to a piped 60 but weighing 23+oz.

Sorry didn't mean to come across like you took it.. Now I understand you comment in my Stuffer Backplate thread. Was just really trying to be helpful, wasn't sure Brett or anyone else was on-line because of VSC.
BTW: I did do a search before I posted the back plate question..

To Brett and Bob, I don't remember any thread within the last 2 days that applied to the 60 FP. Maybe I missed it? I've since looked back and still don't see it. Oh well. I tried the search option also and didn't get much from that either. One good reason may be my lack of computer skills. I know how to turn it on and log on and turn it off. I leave the other the skills to the computer guru's or my kids. As far as experimenting with these engines goes I don't do it nor do I try to alter the porting or anything else. I leave that to the engine guru's. These guys know what they are doing. I do not. I was just curious about the 60 FP because I happen to have a couple of them for the simple fact that at one time I thought that any 60 engine could be made to run good for stunt?!?! Must have been smoking something. I am clearing out some engines and don't want to keep any that have no hope. I hope you understand now why I asked. Have a good day.

Maybe, maybe not. No one has actually tried it, to my knowledge and that is definitely the only way to tell for sure. I don't anticipate there are a lot of people looking in that direction. There are just so many other engines in this size/power range that are *known* to work well, and the amoutn of time it would take to even find out whether or not there is any potential is worth the price difference. And, to be honest, there's not a lot of new development in the 2-stroke area right now. Between the PA and RO-Jett, you can get pretty much any sort of run you want, and power is not an issue. All the significant development is being done on 4-strokes, because there is not nearly the amount of accurate information available nor has there been any general consensus on how they work best.

By all means, if you want to go down that road, go ahead.

p.s. upon futher consideration, if you want to run a muffled 60, why not sell the 60FPs and use the money to get a SSW Magnum 53. If you are going to run that sort of engine, you couldn't possibly need more power than this engine will provide, and it's already sorted out. bb

I only get 4 weeks of vacation a year. I am going to the W/C as a team supporter/Ted's mechanic, and that and the NATs is 3.5 weeks all by itself. If I go to VSC, I can't go to the W/C and the NATs. So here I am.

Brett, I have taken your advice and have listed the engines here and on Flight Lines. I am just trying to clear out some not so needed engines. The kits will come later..........

I club member here in the Charlotte area had a FP60 on a very large plane and it would run away after a few loops. I told him how to rework the FP40 sleeve and that worked so well he did the same mod to the FP60 sleeve and it worked well and the motor runs like a reworked FP40.It pulls just as hard as a ST60. I can't remember what muffler he has on it. Well I went and found a picture of his set up. Plane is about 750 sq inches

Bill,
I have a SSW ASP 53 from Leonard Neumann on my newest airplane. 625 sq in 51 oz. I have flown it only 4 times so far and the engine ran great. I have read great reviews on the engine and for $150 it is a great value. It's true chrome, ball bearing, 10.8 oz engine which should last a long time. I have learned to listen what Brett says and I'll let you know how the trimming goes and what my setup ends up being. Can't go wrong with the SSW ASP 53.

The real problem on the FP 60 is weight. 10.8 ounces for my Magnum 53 that will pull as good or better than an ST 60. A little over 11 ounces for a PA 61. Sure, the FP is cheaper, and yes, we can get it to run. But 18 ounces!!! We are not talking two or four, we are talking 7 additional ounces of dead weight. That, in a nut shell, is why you don't see people playing around with it much.

Needless to say I was very suprised to see a plane with such a heavy motor on it. His plane is a very simple profile but it is very light for its size. I didn't know he was going to make the changes to the 60 as he had done on the 40. It did run very well. The plane is as big as a Patern Master.If you look close you will see he has a dural gear coming out of the wing and he can remove the gear and change it for a longer one for grass fields.

That, and the fact that you can get any number or other engines that are ALREADY known to work for similar money and 0 fiddling. Other than just fiddling for the educational aspects, there's just no reason not to just go get an engine that someone else already figured out.
