I have been watching Joseph Higgins builds


Looking through his models I noticed the ignition module he uses
CDI using a Hall effect
Went looking and found this on aliexpress

https://vi.aliexpress.com/item/1005006210777871.html

Seems similar to what is commonly used on the hm-01 model hit miss engine however the model uses points from what I can see

I was happy to try one for the team😂😂
They arrived this morning - usual 2-3 week shipping

A quick lash up and we have spark 😀




Anybody else have experience with them?

Looking through the reviews of the

RETROL HM-01 Hit and Miss Engine Model​

An example of a model using module with points.


There has been some mention of unreliabilty with the module. Some dead on arrival.
Cheers Jeff

Ps. Now I need to stop casting parts for engines and learn how to build them.

The good thing about Aliexpress is: :cool:
  • it is hit and miss (just like those engines).
  • it is like paying for the drinks at the pub, money is gone the moment you order, headache might follow later. (depending on amounts and over all outcome)
  • there are all sorts of "fakes of fakes", you usually do not know. (sometimes the seller does also not know)
 
I have used that module on several of my models but not from aliexpress. That price is for a new customer and since I have bought from aliexpress before the price is some higher but still very good.

The module and the 1/4-32 spark plug together usually sell for over $50 elsewhere.

This is for my Siamese Bee engine and I would prefer to use a higher quality

set up. Anyone have a good source for electronics and how to set them up? This calls for two double D batteries in parallel, can I use a lithium battery instead?
 
So, run it like the print says to.
Thanks
If you aren't thrilled about the D cell setup, do some searches for glow drivers. There are some set up for multiple cylinders, and the systems run on a higher voltage. They control how much voltage goes to the plugs even with a higher supply voltage. The RC world has them in various setups.

I will look into that, thank you again.
 
I'm running these AliExpress glow drivers on my 5-cyl radial (one dedicated per plug). So far so good. Specs say 6-24V input. I'm using a spare 3S RC Lipo battery.

While you are on Ali, I can vouch for these harness plugs. They have a very positive internal spring that engages the plug stem. Note that there are 2 sizes, for regular glow plugs & 4S plugs which have a slightly larger diameter stem.
