ok that sounds plausible

got the new cylinder from xenalock with piston and have no problems with fuel

when you not run the engine on the limit and give a little more fuel as it takes i think thats ok

coxaddicted Wed Jan 30, 2013 7:24 am

You mean a rich needle? Yes, a little bit but it does not solve the problem completely.

I like to say the same than Mr. Goddard, but didn't find the right words.

The problem is, that synthetic fuel burns completly. The section between bal and socket (piston/con rod) has no bearings.
Normally castor based oil is recomended for cox engines. This has a sense: castor oil does not burn completely, therefore the bal socket and piston is allways lubed, which is with synthetic oils not the case and than happens what Mr. Goddard wrote.

If you would like to do something good for your engine, add a little bit castor oil from the parmacy, there is a mixing excel advisory somewhere here or visit the website of Cox Engines International (there are some tipps for fuel). Castor Oil compounds very good with normal available fuel and the piston will last longer.

BTW: It also smells good lol!

The postman rings Huh...

voila, next one, engine has good compression and it is more complete than I thought. Also the very rare chassis holder and a aluminium skid plate (ver russian method made tongue

) are included. Nethertheless, I am very impressed about the overall condition alls looks to be fine and it seems that this car run not very long ( can't find any castor stain)

Looking very good Chris.
Not many people call me Mister.

Cur

Very Happy

Yes sir yes Smile

This morning i partly disassembled the engine. Looking good overall, head glows fine.

I was surprised, that my enemy the black delrin backplate is not broken this time lol!

The pre-owner made a mistake by assembling the clutch (has forgotten to add 2 screws Huh...

)

No more work to do. I think I can re assemble everything now.

Regards

primera_p11 Thu Jan 31, 2013 11:11 am

also eigentlich könnten wir auch auf deutsch schreiben lol!

ok when you use 2 screws you can change the rpm´s where the clutch gets grip in the clutchbell

coxaddicted Fri Feb 01, 2013 4:10 am

Yes that could be, but the manual says 4 screws in total. Huh...

you read the manual What?

coxaddicted Fri Feb 01, 2013 6:26 am

Of course, there are some helpful tips (like: grease the pilot shaft every 5 runs in order to prevent wear out of the clutch bell bearing)

primera_p11 Fri Feb 01, 2013 7:32 am

yeah jok. problem is i don t have a manual from the cox f1 only from the mini copper and at the time i build the f1 there was no manual available so i improvise

coxaddicted Sat Feb 02, 2013 5:03 am

I will try to load up here the english manual soon. I have also the manual for th cox.gtp cars

I have recently purchased some engines like Tee Dee's a Pee Wee and a Black Widow.

I am thinking of converting a Tee Dee 0.49 for my Kyosho Cox (The one I bought in parts).

Today I made a drybuild, it is just an idea but maybe it works Huh...

bernie has new carburettor assemblies to suit the TD

Thanks Ado, I have already seen this nice carbs.

But I would like to use the Original Kyosho-Cox muffler. It is running on the bee- type engines without any complain (except oil pollution Very Happy

) It is just an idea and I do not know yet if it will work.

I also ordered some parts for the Small Cox Logo

stocker (my push-rod was broken). Now I have enough spare parts and I hope I can run it when the weather gets better (I will try to make a video, did not seen a cox gtp running yet).

MeerschaumSteve Tue Feb 26, 2013 2:05 am

That TD looks great as a car engine!

I hope you can get it working, would love to see it running.

Me too! As I am becoming a r/c pilot at the moment, the cars have to wait a little bit Sad Goodbye

But I had a nice letter in my postbox today!

Oh, some nice parts Smile

Hope that the weather here in germany is going better now to test your car.

Uh ya, after a short sun period it is snowing again Cold

@bnitram thanks for making me the flywheel, it is looking great. Can't wait for your experience with the new designed throttle control. You're doing great work in engeneering Beer Cheers

Regarding the other projects: I found a spare body for the cox stocker which should almost fit on the chassis.
It is a Porsche 962c (I think from academy models, 80'ies), the wheelbase is fine, also the gauge.
We will see if it will fit after some modifications, I already posted the pics in another topic, but I think topics are more lively with pictures, therefore again:

I also started to do some TLC on the Espo Larousse, it is getting a new receiver/transmitter (Kyosho KT 200 2.4GHZ) today because I needed the old one for the traxxas slash (same type of radio).
Yesterday I mounted new front tyres and rims. It also got full ball bearing on the front wheels in order to get a little bit more performance. I will mount also newly rear wheels but I have to glue the tyres on the rims first. The old rims had some dents.
I also recover the driver figure, so it is even looking more realistic Wink

.

After a very hard season last year (I blowed more than 1 litre=1quart trough this car which means over 60 full fuel tanks in 4 months) the body need also some work. I have to fix the lexan body on some positions.

Regarding the engine: I ran about 3-4 litres trough the engine in total now. It has still good compression and is running fine.
I wonder how long a cox piston/cylinder will last Huh...

I gave my best.
Hope that the snow go away very quickly. Would test my throttle and see your car running.

Yes weather is xshit. Today I installed the new KT 200 RC which I won on Ebay for 11,50 Europas (NIB, unbelivable Very Happy

)
The fail safe is set, waiting for better weather now.

coxaddicted Wed Mar 13, 2013 3:24 am

Here is a pic of the new installed transmitter for the Espo. You can see also the red KB backplate and important: It is no more a ghostdriver Very Happy

Lookin good man! Hope you make a video of it running with the new setup.

I'm also very curious about how well the KB backplate works with the throttle and the car. That's an upgrade I'm considering for my GTP.

Yes, I think the cylinder could ,,digest'' more fuel. I will have to fit a nylonstocking as an air filter because the kb backplate is screenless. I am also thinking about to remove the base of the slitted exhaust ports for more exhaust timing (no time yet due to other projects).

I hope the crank is happy with some more revs. But in overall the engine is still the one I purchased in 1993 with the car and is very reliable.

coxaddicted Fri Apr 05, 2013 2:16 am

Hey guys,

Yesterday, i tried to start the updated engine.
Sadly, it does not start properly. It smells like burned fuel and the engine runned a couple of rounds but died quickly.

The starting procedure was:

3 pumps with the engine primer
Half throttle
Needle 4 turns out

Any ideas ? No air in the fuel line, Glow plug is good battery too.
