The DL-50 and DL55 share the same prop hub and muffler mounting dimensions as the popular DA-50R

It is a great way to get into gas powered aircraft without breaking the bank!


And if you already have a muffler/header for a DA50/100, it will just bolt straight on.

If you are looking for a 50cc or 100cc size gas engine, that is light weight, powerful, of decent quality  the DL is an excellent choice!

What about the DL-50R model, is this a newer or different model than the DL-50?
NO , There is technically no such thing as a DL-50R , Its just a letter added on by some sellers to make the name sound more like the DA-50R.  The DL50 is the DL50 , there is an earlier version with cast engine mounts. And a newer version supplied with machined standoffs from the factory, and thicker mounting lugs. The new version also has the Walbro pump tube tapped into the reed block instead of the crankcase. 

How do I tell I'm getting the latest version engine?

Quickest way to check is to look at the colour of the prop shaft, if its silver/yellow gold in colour it is the latest version.
If its black/charcoal it is an older stock engine.

 
What 2 stroke oils available in Australia do you recommend?

Castrol Active 2T is a good run in oil at 32:1  . There are many others available, but use good quality brand name products
After run in Full synthetic - Castrol TT at 45 - 50:1 , Belray HR1 at 45 - 50:1 , Redline Racing at 40:1 are some of the many available from motorbike shops / auto parts stores. Use good quality brand name products and be accurate when measuring your fuel mix. Add oil to container first, then add the fuel to ensure good mixing.
 
32:1 is 31ml of oil per litre of petrol
40:1 is 25ml of oil per litre of petrol
45:1 is 22ml of oil per litre of petrol
50:1 is 20ml of oil per litre of petrol
