RE: RCAero JC Engines & YDA Engines
Bob T. I think yours is the original batch from OZ. Check the plugs anyway. RC Exell ignitions don't like 6v. Especially the older ones.

Got the day off so have been trying to give all of the suggestions a try.
First one, bat direct to ign, no change[>:] checked battery like I said it is a 4 cell sub-c 3k ma pack no load reading 5.2 with a load 5.0 even, So went bsck thru fuel system nothing found, Decided to pull carb and do a complete tair down under my 10power bench glass, Reed side first nothing that could be seen , reeds lay nice and flat on a piece of glass both ways. So on with the pump/needle side and and still nothing, removed hi/lo needles and checked them with an eyepiece they look normal and symetrical as you turn them, Fresh can of carb cleaner and back and forth through all ports all drippings on to a white piece off hard paper, nothing that I can see on the paper after it dries, Then blew out all ports with 20psi air.
Re assembled carb again cleaning each oiece as it was assembled. installed to engine, got the engine back in the bird set needles at 11/2 fueled it up, set full throtle and choke cranked till it poped reset choke and throtle about 6 cliks and we are running about 3k on the on bord tech let it warm up a bit idel down to about 1800/1900 rpm, throtle up and it goes to 6998 rpm Running a 20 X 10 Zinger Pro. great throtle responce.
Now I have 3, 8 minute runs and at all rpm's so it looks like we have resolved my problems
So untill next time all I can say is THANKS for your suggestion
Now if mother hature will just cooperate with some good weather we will try for a maiden

I see the JC 60 and 30 in the RCU market. I went to the JC website and they show the following
23cc evo
28cc evo
30cc evo
51cc
60cc evo
102cc
What ever happened to the 38cc ? I thought Bobs was going to be selling the JC/YDAero or does Plane Addicts = Bobs ?

Bob hobbies is not Plane Addicts. We are a seperate company working with JC engines on promoting there engines. I have performed flight test for Henry when he had the YDA and JC lines. Now we are working on our own and importing directly.

RE: RCAero JC Engines & YDA Engines
Hi Bob,
This is good news. Good to hear your engine is running well.
These engines like a bit bigger prop. Try 23x8 - you should get good solid performance on that size. Forget about static max RPM. You will find that in flight, you have very good midrange power on a prop of that size.
Tom:
Congratulations on your win!!
You show-off you

RE: RCAero JC Engines & YDA Engines
I have been told there is a new Distributor for JC Engines in the US, or PlaneAddicts who have been frequent posters here.
PlaneAddicts has come across as a standup guy who looks after his customers and knows his stuff.
Needless to say, I assume they will take over warranty support for JC in the USA from now on?
The latest batch of YD-A engines was made by JC Engines (for Henry) so I assume PlaneAddicts will support those as well?

RE: RCAero JC Engines & YDA Engines
A diaphram change is only necessary if you are using this new b.s. they are selling, ethanol, we are fortunate to have one station around here selling gas, no ethanol, that does not play hell on the internal parts of the carb. Government is about to cut out the real gas they are going to make him change over, what kind of b.s. is that.

The problem with dealing in JC engines is like opening a box of candy, You never know what you are going to get and believe me I know.

It is especially the "flavor" that is indescribable

Just a little up date now have 1 hour and 10 minutes of time on the engine and I realy like what I have, Next step isit to get some weather on a day off and go fly this bird. If my on line order for props shows up will us a 23 X 8 if not will be a 22 X 10. and I think I will be changing the oil to synthetic at 50 to 1 after a few more tanks just din't like the mess, worse than the birds I have to clean as a kid when working to get rides

RE: RCAero JC Engines & YDA Engines
Good to hear Bob
It wouldn't hurt to change the oil now if what you are using is too slimy or messy. As the engine runs in it will make a mess from the exhaust anyway and you want that "black stuff" to come out of the exhaust instead of staying in the engine.
My favorite oil here for them is 40:1 of Castrol TTS (the all synthetic one) or 40:1 Redline. I use that as a standard mix for al of the 2 stroke enignes I have around the property as well as my RC enignes. I have been testing both oils side by side for a few months now with no appreciable difference between the two on engine internals (Wear or carbon buildup). I am running one in most of my engines and the "new mix" in a selected 3 engines that get flown as regularly as any of my other engines as they are in my favorite planes). I am only changing to the new blend because that particular oil is very much more readily available here than the other one and is also certified to the higher JASO standards than the existing one of the two. (We can't get Stihl Ultra or Pennzoil here [
])

Now to the nitty gritty of the situation lol.
We are not doing anything with the YDA line. That was Henrys baby and I use to just fly for him. Unfortunantly stuff with that went by the way side. He had the right to the motors from what I understand and I havent heard from him in a while. Maybe one day they will come pack out on the market because I really enjoyed these motors.
Now the JC engines are another story. We have picked up there product line ourselves after the Henry ordeal. We are an factory direct dealer/distributor for there line of engines.
So for warrent at this momment we are able to service the new 30cc and 60cc motors that we sell. We are working on becoming a full service center for JC engines.
As for the YDA warrenty I dont have permission or a way to get parts on these motors since I havent talk to Henry in months. So I guess these motors will have to be sent back to Bobs Hobbies for them to handle the warrenty on.
I will post pictures of the 60cc and 30cc with some info soon for everyone.

Hey Ari,
I have ran the motor on the bench. I have a Pitts bipe coming to put it in. I will have a bunch of info and pictures for you guys soon on both the 30 and 60cc motors.

New?? Where have you been hiding? Lots of this country has been using it for over 20 years with no problems.
