Looks great! I'm even more excited to get mine now! I hope it arrives soon. I'll definitely be checking the latch to see if I got the same early batch you did or if they fixed it already.
Yeah Hi John. I did think seriously about it however they do check every engine runs. I noticed at the end of two runs the latch was not latching see 11:00 because of the 45 degree slope. So...is the slope done by CNC and they're all like that or individually ground and mine was wrong? If the whole batch was done I guess Jin wouild like to know if he doesn't already
I emailed him. I guess he knows already or its a one-off, but it may help him. It was a fun challenge to me so I didn't want apologies or whatever, he'll be busy enough
I know that Jin and the other manufacturers watch these videos and include improvements in their manufacturing each time a new batch of engines is made because I have several similar engines purchased over time and the early ones (from 2020) have issues that were addressed in later runs.
ruclips.net/video/XbGQm47k3As/видео.htmlsi=YG09mrUtnzZoXrZh&t=727 see my slower spring. I took it out when fixing the valve latching. More tweaking on the latching could reduce the cam bumping in the miss, and the spring...you have inspired me to try now!! Difficult in ths scale
I'm new at these engines and they are so fascinating. Can you recommend a good H and M to start with. I have been looking at the Retrol HM1. Any thoughts. Thanks Jerry
Welcome to the comments Jerry! Absolutely choose the Retrol Musa HM-01. It's pretty much the pinnacle of Chinese H&M model engineering and likely to give more than one lifetime of service, high quality. I got the base and fuel tank too.You've probably seen my vid on getting the best ouit of that motor ruclips.net/video/opSh_U3HnBs/видео.htmlsi=w4qhIr0IpGXDiVGt and my general assembly here ruclips.net/video/opSh_U3HnBs/видео.htmlsi=xb6RtlL7xr45CrKP
Thomas, was that piece you heated a turned a machine error on just this machine , a defect so to say? If you had broken it, could you order a new one. Great video for sure😎
Hey Jerry. I have contacted Jin, he appreciated the feedback and is looking at the engines and trying what I did. Whether it affects all in the batch, It all depends whether this bit of grinding at his factory was mechanised machining or someone on a grinder. Jin is good with parts and if there is a problem with the engines he'll fix it and offer replacements, and future batches will be correct. Looks like engines still run with this defect, but I suspect will begin slipping off the governor step leading to thrashing
I always considered this just an ugly engine as it does not duplicate a particular style.....but, to see how interesting the mechanism is and how it runs now puts it on my list to own at some point. I had the M92 and have an HM-01 on the way.
A beautiful 6cc version model engineer made, really must have worked skilfully to get it like that. Very nice...I'd seen it but I doubt this little flywheel model can runj that slow
I saw that, was momentarily embarrassed, then thought: if it's not ok for my engine mates, who could it be ok for? Surely no-one would be thoughtless enough to point it out? :)
Part 2 is at ruclips.net/video/c5FsGx1oqss/видео.htmlsi=CkA17jH1xt-XaFzC
thanks !
You guys do a good job :)
Neat engine 👍 Jin done a great job again
agreed totally.
Excellent video as usual, love this style of hit and miss creating
Welcome to the commemnts, love the feedback!
Your excitement made this vid :)
So glad you enjoyed that! Loved your comment!

Hi Henry! How are you man! let us know pls :)
I presume you showed this to Jin before posting it on YT....
will he make this latch improvements based on your work ?

Do you think you can slow it down and/or get a longer miss cycle? Possibly reduce compression and weaker govornor spring?

Thanks for saying Hi Anthony! It is a bit different

This one runs a fair bit slower.

should clean your nails mate
