How do I tell I'm getting the latest version engine?
On the DL50 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.
The mounting tabs are thicker, and the pulse tube for the carby is tapped in to
the reed block, not the engine.
We only stock the latest version
engines, factory direct.
Are spare parts available?
We stock all DL engines spare parts.
A detailed parts diagram and parts price list is on the parts page.
Warranty
The manufacturer's warranty is that "the engine will be free of defects at the time of sale".
In addition to the manufacturer's quality control, we inspect all engines
physical defects before shipping to the customer and provide a
12 month Australian Warranty for manufacturing faults with the engine (Note:
We do not disassemble or test run or tune the engines)
This Warranty only applies to engines purchased through DL Engines and Hobby
Australia.
Engines purchased from Ebay or from other
sellers will not be covered by us for any warranty claims, nor will we
act as an agent for a claim to the manufacturer for warranty claims on engines
not purchased from DL Engines and Hobby
The engine is not covered by warranty for any issues arising from misuse, poor tuning, wear and tear, crash damage or faulty/poor or inappropriate installation by the end user. The ignition warranty does not include damage caused by supplying too high an input voltage, vibration damage or use without a spark plug firmly connected.
Warranty is void if the engine is disassembled without authorisation from DL
Engines and Hobby
Warranty claims must be accompanied by a copy of your original invoice, and warranty card with Matching Serial number.
Warranty is return to base, and the cost of shipping and insurance back to DL Engines is to be paid for by the purchaser. Insurance on shipping is highly recommended. We cannot be held responsible for items lost in transit sent to DL Engines and Hobby Australia.
Warranty is not transferable
DL Engines and Hobby
Please contact us first regarding any issues before sending engines back to us.
We might be able to just ship you the replacement part, depending on the claim.
What about the DL-50R model, is this a newer or different model?
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 instead, and thicker mounting lugs. The new version also has the Walbro pump tube tapped into the reed block instead of the crankcase.
I have seen DL50's and 100's cheaper on Ebay, why buy one here?
To start with, we are the Authorised DL Engine dealer/distributor in Australia. We deal direct with the factory.
One of the conditions of being an authorised agent, is a minimum advertised retail price.
Most Ebay sales of the DL50 are drop shipped from China. The seller does not have stock, and pays an agent in China to ship the engine to you without ever seeing the engine themselves.
We import the engines and keep them in stock ready to ship. We also list engines from time to time on Ebay to cater for those that prefer to purchase through the ebay system
The engines we import are thoroughly examined by us for physical defects. We will find most manufacturing problems before they get to you (note: we do not disassemble or start the engine). You can be confident in getting a complete engine, with no parts missing or obvious manufacturing defects.
We include our own English instructions.
We have already paid any import duties etc, so you know exactly how much you are going to pay.
You get the engine faster, as you are only waiting for shipping from Western Australia, not China.
If you do have problems, you deal with us in Australia, not an overseas hotmail address that may disappear at any time. You can also be confident that we have the necessary backing direct from the manufacturer.
Seen photo's like this.... They are not the sellers stock, but from the Chinese drop shippers website.

What make is the carburettor?
Walbro
What about the engine bearings, are they Chinese bearings?
No. The DL engines are fitted with quality German made FAG bearings and Japanese made KOYO bearings.
On the DL50 Can I Rotate the Carby 180 degrees, as I need the throttle linkage on the other side?
Yes. Undo the two bolts securing the carby and reed block to the engine, rotate,
and bolt back on.
The new version even has the pulse tube for the fuel pump connected direct to
the reed block. You no longer need to extend the tube if you rotate the carby.
Having the pulse tube tapped into the reed block also extends the life of the
tube, as it is better insulated from the engine heat.
Who makes the ignition?
Ignition is made by RCCDI in china
Are the DL50 mounting dimensions the same as a DA-50?
Prop hub pattern is the same.
Muffler mount is the same (you can use mufflers designed for the DA-50 with this engine, bolt straight on)
Engine mounts also have almost the same spacing. If you previously had a DA engine installed, you can bolt the DL engine in place if you use the engines mounts supplied with the DL Engine. There is a 1mm difference each way in the mounting pattern. Most of the time it will bolt straight on if you loosen your mounts slightly, fit the engine and retighten or use the supplied machined standoffs. Depends on how accurately the original mounting holes have been drilled on the plane, and how much 'extra' (ie oversized mounting hole) movement is available in your existing bolt holes.
The overall physical dimensions are slightly different. If you where to bolt the DL in a plane that had a DA in it previously you will find the muffler will sit about 4mm further back, and the prop hub will be a bit further forward.
The muffler supplied with the DL50 is slightly larger, compared to the stock DA one.
You can rotate the carby if you throttle linkage is on the other side.
The bolts used on the DL50 are all 5mm metric sizes.
Mounting bolt pattern is 80mm wide and 67 mm high
(centre to centre) see mounting Template
Distance from back of mounting lugs to face of prop
hub is 102mm , and the supplied standoffs are 68mm.
Total length of motor from back face of stock standoffs to front face of prop hub is 170mm
Do you have a shop/store I can visit?
No, we are mail / internet order only. We are not covered by insurance for retail customers visiting the premises
Ignition Battery
4 cell 4.8v 1200mah+ pack recommended.
5 Cell 6V packs can be used, but must be regulated between 5.2 and 6.0 volts.
2 Cell Lithium Ion / Polymer Batteries can also be used. But again the voltage must be regulated.
Voltages above 6V will damage the ignition. This is not covered by warranty.
A freshly charged 5 cell pack will output above 6 volts, and a regulator must be used.
Disconnect the battery from the ignition system while charging the battery.
The ignition module should be connected to the battery through a heavy duty switch. Standard receiver type switches that come with your radio are not suitable.
We recommend a heavy duty switch with a built in charge jack that disconnects the battery from the ignition when the switch in the off position. This also provides a handy connection point to check your battery voltage before flight.
Spark Plug
Uses a NGK-CM6 spark plug.
Be careful not over tighten the plug. The engine head/thread is aluminium. If you over do it, you will strip the thread.
The recommended torque range is 9.5-10.7 NM (7 to 8 ft-lbs).
Finger tighten the plug, the using a spanner tighten it about another 2-3mm max.
Running in or Breaking in the Engine in the Air
Use petroleum based oil, light loads and light throttle use during the first few hours of use.
You want to give the ring a chance to bed in to a closer fit to the cylinder wall.
You don't want to overheat the engine.
Ensure it is adequately cooled, with sufficient air flowing over the cylinder head cooling fins.
Use a smaller prop (22x8 Recommended for DL50 and 26x10 for DL100 when running in) and lower throttle settings.
Full power climbs, and hovers etc are not recommended during the run-in process.
Correct (not excessively rich) fuel air mixtures and correct fuel to oil ratios help here.
The additional oil in the fuel mix provides the extra lubrication required during the break-in. You do not run the engine mixture rich like you would with a glow engine for break-in.
