Default New DLE 20-RA

Received last week, i've tested the new DLE.
868g. all included.
New RCEXL A02 #6 ignition with spark plug cap angled at 120
Now i'm testing the engine on a bench to finish the break-in and to take rpm numbers.
Sweet running, easy adjust, nice look, and good power. Easy fit on WWII warbirds with no cowl cutting !!!
WELL DONE, DLE .....

I really love this little engine, and i'm impressed with current DLE production. On single cylinders, we have now available two options on 20cc class, side/rear, the 30cc side and 35 rear, the 55 side/rear, the 85 side, the 60 twin, the 111, 170, the 222 four, ..... What else ?
Soon we will see more DLE creations.... and some amazing surprises ..

Best regards

OMG!! that's really nice! I have a DLE 35 RA and I dream for this 20cc beauty!

What prop size is swinging?

When I get one, I will use an Xoar 15x8...

Please let us know the rpm numbers of your tests... thanx!

I've been flying my old 80" Hanger 9 PT-19 with the new DLE 20 rear exhaust for 3 weeks now. Performance has been outstanding! It started and ran great with no adjustments at all. Using a 17x6 Valley View wood prop the plane flies much better than with the 1.20 4-stroke glow engine I used in it before. I couldn't be happier with this new engine! Another good feature is with the rear exhaust the engine will work in narrow cowled planes like the PT-19, Tiger Moth, Ryan STA, lots of warbirds etc.
I'm ordering another one for my H-9 Tiger Moth this week.

Are the exhaust ports the same on the DLE20RA and DLE35RA?

I know the muffler outlets are not the same and there is no TBM silencer option for the 20RA.

I had the idea of trying a 35RA muffler with TBM silencers on the 20RA. If it fits, In theory it should be quieter with similar back pressure to the stock muffler.

How many rpm are you getting with 17x8, 16x8 or 17x6?

Does 15x8 will be to short?

DLE20 and 20RA have the same exhaust pattern, same size, gasket and M4 bolts.

I do not check rpm much just put on prop fly the airplane if pulls like I want -great joy.I think 15x8 would not be enough prop for DLE 20.I like 17x8 xaor or 17x6 VV.

Hi,

Can those that have the DLE-20RA please check your engine and tell me if yours has any play and clicking noises like in my video below.

Thanks

That is the clearance of the rings within the ring lands on the piston. It is normal and means nothing. You will find that on all single cylinder engines

Thank you for that gold nugget of information. You're right.

Now that i knew where to look. I took the muffler off and watched the ring as i rocked the prop and can see (and hear) the ring move in the lands and squeegee out some oil as it does so.

The noise is not so pronounced when the engine is hand-held. Adding the muffler and the metal test stand amplified it quite a bit.

Thanks for the help. Much appreciated.

I know because I've been there and done that - seen it for myself.

You can buy a new cylinder head for $64.95 from Tower, or have someone install a helicoil to repair the cylinder head.
Sounds like you over torqued the plug and damaged the threads. I would not be very hopeful of the warranty covering it;-(

This is normal with the 20 BUT! sounds like you have lost compression, If your using the stock spark plug throw it away and replace it with a NGK CM-6. I had to send my 20 back because the stock plug pulled the threads out of the head. Lucky it was still in warranty! The nocking is just the piston rod rocking at TDC.Looks good
