Status: offline 		Guys,

thanks for the kind words. Like the look as well.

did a quick try with the 400 because it should go on display at a local exibition between christmas and the 6th of Jan. but it is blowing from all cylinder heads. Compression is very bad. Small setback. I have to change the cylinder liners too. They are so corroded at the top that the cylinder heads can't keep them sealed.
I have ordered new ones from HK, they are 8 bucks a piece so not that bad. Will be 2013 before the engine runs. Exhibition will be static then.

Apart from that not very motivated for RC. The news we are getting from connecticut is simply devastating and thoughts about it keep going round in my head. I have two kids about that age and I cannot even begin to imagine what those parents are going through after those senseless and brutal events.

My heart and prayers go out to them.

Sorry for the OT.

Philipp

I know people will go on about it being unconstitutional (which is rubbish) but honestly, they were children at school. And what of the people just watching a movie? or the police officers attending any number of issues. I think America needs to have a long hard look in the mirror and the govt need to act to protect their population.

Irrespective of the long term changes, this is another tragic event that should not have been allowed to happen.

However, continued discussion of this can go wildly out of bounds and make enemies of friends, so let's drop it now please.

Had some more bad news today and just had to get my mind off things so back to radials...

sorry, not the 400 yet but (almost) as good.

Sounds great Rev, and it looks clean as well on the low oil fuel? as much as you can tell from a slow run anyway.


Sadly i did not have the weather for any radial action, its too cold and its just a pain to start it. So, some V twin laser action did the trick,  but alas no video.

It is a lot cleaner than the 400, even though it is still running on 10% oil.

No flying for me either, lots of sled action with the kids

Status: offline 		Hello Guys,

I Follow this Forum since July and im happy to see so many  Enthusiasts in radial engines. Im  also a proud owner of an ASP 400 from hobbyking. so far so good. I struggled a little bit to get all cylinders running until I followed some suggestions from Tom.

Have any of yu ever heard from this machinist guy named George Luhrs ?. He built the smallest 5 cylinder radial engine for a contest sponsored by sherline tools in 2001. Unfortunately i havent seen a video of the engine running and I dont even know if the guy is still aive but is quite an achievement what he made. his webpage is minimodelengines].com  (remove the square bracket to go to the webpage).

Regards,

Israel

Being a model engineering enthusiast myself, I am quite familiar with George Luhrs' micro engines, he has built many different types. He is not alone, it seems many model engineers try to make things as small as humanly possible. I suppose that is the challenge they seek to conquer.

If you haven't yet, you should peruse the Model Craftmanship Museum website, by the owner of Sherline.

Status: offline 		  Hello Olivier,

Do you have any news in converting the ASP400 from glow to,ignition?. I think i read a post from you where you mentioned doing some research in to adapting some ignition system.

There was alsomone guy in this thread  that mention that some small company wanted a sacrifice engine for the sake of making an ignition system for the ASP400.

Somebody already ventured into it?. I have seen some youtube videos of a guy running gasoline/ ignition on a ASP400 but he adapted 5 independent ignitons.

I have also seen that some hobby stores sell ignition systems for some specific 9 cylinder radials, as well as some spare parts, kits from plugs, distributors, coils, hall sensors. But nothing specific for a radial 5 cyl such as the ASP 400.


Regards,

Israel

Status: offline 		Hello Israel,

RCEXL is working hard about ignitions for radials ; first of all, the 3 cylinders ignitions will come  very soon on  references 13XX, a very good new for all SAITO Radials 3 cylinders owners and customs engines ! 
1301 = 3 cylinders / 1/4-32 sparplugs sockets bent 90°, 
1302 = 3 cylinders / 1/4-32 sparplugs sockets bent 120°,
1303 = 3 cylinders M10 (NGK CM-6) sparkplugs sockets bent 90°, and
1304 =  3 cylinders M10 (NGK CM-6) sparkplugs sockets bent 120°
All LiPo  2S compatibles, expected street price 140 USD

RCEXL is also working on ignition for SANYE Radials 5 cylinders, I had a lot of discussions with Xu Liang about the market and number of radial engines sold in the world.
I'm developping a personal solution for specific hall sensors positioning on the back of the engine with my "upgrade" rear cover ( quite  impossible with original rear cover).
The working solution with 5 x single ignitions is far too heavy and need a lot of place.
With my upgrade cover, those engines can now run with methanol based fuels with 7% lubricants, and they  are ready for a future spark conversion to run with gasoline + 3 % synthetic oils because the intake gaz goes through the crankcase for better lubricate before suck by intake pipes ( As used in EVOLUTION-UMS-SEIDEL and MOKI engines )
I think we will get a technical solution for SANYE Radial engines middle or end of 2013.

Olivier, those parts are abominable. Should have been factory rejects with all that porosity. And what about surface finishing of the parts before installing them into an engine? Makes one wonder if the Sanye factory pulled all of its QC inspectors off of the radial engine line to another department!

Status: online 		There does seem to be a massive amount of flaws in the material, and the grinding leaves more than a little to be desired thats for sure! the problem is will a replacement be any better? Also i doubt the imperfections will cause a problem for the engine as long as they dont form cracks and break over time. if the crank was in a bush not ball races then clearly something would need to be done.

@ Jaav - i can see the problem, not sure what to do about it mind! but in the 2nd video the guy did kinda throw it at the ground and hope for the best, in your video it was hard to see as the model was a long way away. it seems however that rate f decent is fairly high and the speed it is landing at quite fast, is that as slow as it will go because it seems to takeoff at a far lower speed?
