Default Picked up some old stuff. Questions.....

Hey all. I don't post often, but I picked up some older RC equipment today, and I am unsure as to what its exactly worth.

Brand new, just out of the box, and run once today. OS FS-90 "old style" with choke and rear facing push rods. I have original box, manual, tools, valve gap spacers, straight pipe exhaust with nut, stock muffler and decal sheet. This thing is dangerous to start since the plug angles towards the prop.!!!

Two almost mint JR Max 4 transmitters with gold AMA lables, with buddy cord. One of which has a channel 41 crystal and is in box. Box is for the 6 channel version though. Also includes I beleive instruction manual.

This seems to be rare, but and old kit trainer with a near 70"+ wing span made by CG. Has no other decals other then the old style CG emblem. Has a snapped vertical stab (fixable) and a small hole in the covering. Anyone know the name of this trainer?

I picked this stuff up today. As i said, I have ni clue what this stuff is worth, just curious.. Any ideas???

It is hard to put a number on what you have. You may want to do some research in the RCU Market place and see what these items have sold for in the past, and that will give you an idea as to what to ask for yours. Good Luck, Dave

The OS engine is actually better (personal thought) than offered today. I've flown many OS & Enya FS engines and can tell you from experience that you will come to love the push rods being behind the cylinder when you have a mishap. The push rods mounted forward of the cylinder can (and will) take a beating. Too bad you ran the engine, it's value is now reduced to half of what it could have been. Many folks would like to find a "never mounted" and/or "never run" older OS90 FS. As far as the plug goes, if you're uncomfortable with it being so close to the prop try a remote glow setup.

Enjoy your new stuff!

Randy

The remote glow setup that they use for Heli's is already on my list. I really dont care much that i started the motor at this point. I am fully ready to utilize it as much as possible. Thanks for the info though!

Don't worry so much about the glo plug facing the front. Thats the way many engines were made in the past. All Enya's are that way.The fs90 I had was awsome. It was destroyed in a crash or I would still be running it.

I have been looking for some info on the old fs90, perhaps it is in your manual or info with the motor.

Does your manual spec what the valve gap spacing for the intake and exhaust valves should be.

I have had my FS90 since 1984, have not run it in the past 7 or 8 years but it has been a very good motor.

Thanks in advance.

Next time I am down in the workshop I will go through the manual. I did once before, but I dont remember if it had that info. I do have the lash tools though, so I can give you specs off of them. I may be down there tonight or tomorrow.

the fs 90 used the same valve lash clearance as the newer fs91 which was .004 to .010 both valves cold. I always favored the exhaust valve with a setting on the high side of the spec.[.008-.010]It didn't make much differemce on the larger engines but I found this to be helpful on smaller ones[.52 or less] I have a .52 that wouldn't run once under load [would falter and slow dowm and most times stop after a couple of mimutes in the air]and was just about to abandon it when I discovered that the exhaust valve needed a little more clearance when hot and set the lash at .009 where upon it ran like a champ

This begs a question; Why buy something when you don't know the value?
