I would like to know about spare parts myself. I'm gonna need them. I maiden flight to day and crashed on take off. Motor was running great and preflight was excellent. Range check excellent. 10 ft of altitudeand the plane rolled right 360 deg. and then nose down hard! Right into the runway. I carried one of my wing bags down the runway with me and the whole plane fit into it to carry home. The aluminum extrusion mount was bent pretty bad no cracks or sign of fatigue. It even has the two mounting ears from the block still bolted to it. I have no worries at all about the mount. I think it is matched to or excedes the strenght of the ears that it is mounted to. Again two ears broke off the cast case and are still bolted to the mount and the other two ears did not break and are still bolted to the mount. The mount is bent up but not cracked. The cylinder has three mushed fins that will probably break off when straightened. I would expect similar damage to any engine that I crashed this hard. I will check about welding the tabs back on and redrilling two new holes. If not spare parts would be great. Well back to the drawing board for me. O, and all you fellas that dont want to use the supllied mount, I'm in need of a new one just send it to me.

skreamer ....sorry to hear the bad news............I hope you can get parts. Try Peak as it seems they have at least a direct connection to the factory.

This will be a good (but unfortunate) test for us. I hope you find the cause of the crash. Test that radio gear ....twice.

I am completly expecting RFI when I run this one in my Yak. I had to go to straight batteries (nimhs) in a CH igniton equipped BME .. A Fromeco and Li-ion setup on the CH was making RFI like crazy....straight nimhs made it go away. I still don;t know why.

Same Fromeco /li-ion setup on a DA was clean. So , I am bringing a nimh pack with just in case.

I wanted to re-start the recently blocked DL-50 thread. Please, can we keep this on track and stick to the topic of the engine, its quality, and performance.

And finger-chopping capacity.

I've never used a side dump muffler on my DA's, but It's definitly louder than the DA wrap around pitts.

I think your talking about a Slimline pitts? DA doesn't make one that I know of. so when you say the muffler is louder than the DA muffler, we assume your talking about the only muffler they make which is a side dump muffler

skreamer, I'm also sorry for your loss... I had time this afternoon to fly mine a half hour or so, I did lean the idle a tad and it is running smooth at all RPMs, the warmer temp today was easier on the thumbs!

The Fuji I had in this plane was just as loud so I don't think it's that bad...My amish neibors chainsaws ect. are noisy also, noise is not an issue at my field as long as I don't get too carried away and fly when their having church, weddings, ect...

I have had no RFI issues so far, range tests are great... If this thing keeps running as good as it is now I'm a happy camper! RCIGN1, thanks for the prop bolt comments. Hamman

Sorry to hear about the lawn dart. Reversed ailerons?

Can you bolt tabs to the case assembly bolt?

I just checked, my engine cleared US customs this morning. Not long now.

Actually your lucky you were using a DL. Neither a DL or DA would have covered your loss. You can now buy another complete DL engine/ muffler and still not have all the money into it that you would have with a DA

And now you are the US stocking distributor for internal parts and ignition.

Skreamer....

After you can look at it again..I know it takes me a while to go back to a pile....hey that rhymes..

Take the plug out , and turn her over and check to see if the crank got tweaked/bent. I wonder how tough the crank is.

I mean that is certainly a lot harder than a propstrike...but just fro reference.

But, I know me,...it takes a while to go back to a pile.

gotta get back to the re-fit....almost done.

Skypilotone, I dont think that would be possible as the carb will probably make extensions verry thin. Also the rear case is cracked through under the cylinder.

Jrjohn, hard pack dirt. I bought a used wood 22x8 msc that met its end on this flight. Thankfully it was not the carbon fiber that is due in on monday. $46 whew!
Yes at this price I can afford to buy another which my WIFE pointed out as she told me to quit whining about my broke motor and plane. 2 for 1 is always a good deal.

Bosshov, crank looks good checked with dial indicator side and front but I'm no machinist.

Skypilotone, Distributor Ha Ha hahahahahahahahahahahahh.

Sent message to Peak about back plate cylinder, gasket, muffler, and mount (have not had one donated yet?). I will keep you guys updated on what i hear back from them. Always happy to be the guinnypig and take one for the team and all that.

I disassembled back plate, mount,carb, and cylinder in about 15 minutes. These engines are so simple. If I can get parts should only take a few minutes to reassemble.

By the way the cylinder looks excellent and has no visible wear. Engine internals were very clean and tight.

You may have to buy the whole case as a matched set but I'm probably wrong. It would be nice to have a US distributor and I don't think the price would have to go up too much. The people selling them now are making a profit. If you could make $100.00 on each engine and be happy you could probably sell them for the same price.

What do we really think the factory is selling them with the ignition to the retailers for now? $125.00? $145.00? Or less? What addes to the cost of may products is the distributorship. They mark it up 100% over the manufacturer and then the retailer marks it up another 50%. But if the distributor sells it direct they get 150%. Not bad ay. Remember you can buy a 47cc pocket bike racer from a US distributor for $179.00.

I wonder if a 3/16 alminum plate between lugs and round aluminum or maple standoffs would have prevented lugs to break? A hole would needed in plate for extension to carb. Capt,n

It would go a long way to making it harder to break, Titanium would be best, ha ha. But certainly any kind of plate, would decrease the risk of tab breakage in a hard propstrike/nose over.

Looking forward to running this engine tomorrow....right before I test fire, I will take a static timing check on her.

CF MEjzlik 22 x 8 will be her first prop.

Ok, break timeover....back to the bench.
