Default DLE 30



Hey all:


New to gas engines, But i have a NEWDLE 30 and have been tuneing it, " The cub it's on is NOT ready to fly yet "

Iwas reading where others are turning 8500 and even 9000

I have an 18 X 8 prop on it. my best is 79??

using shell high octain fuel with 30 to 1 mix echo synthic 2 cycle

Ihave adjusted the low and high speed to what Ibelive the sweet spot...

Also Iread where after break in or about 2 gallons it will get better.

this is a break in propt according to tower hobbies where I read that part....


am I doing right, and is everything just like it should be ?

Thank you

Sounds OK so far, but in the long run, the DLE 30 is more of a torque engine and a 19 X 8 would be more desired.

I just fired up a new DLE30 last weekend with an 18x8 prop and have pretty much the same RPM number. Right around 7800 - 7900. I had to adjust the factory settings on both the low and high end a bit. I did not try to go for higher RPM since it is new and I was a little concerned about cooling in my setup.

I found that something like a 19-6 works best for a CUB or CUBlike plane and 19-8 best for a light weight aerobatic plane. I usually start with Xoar props with the laminated versions being my favorites.

Don't get all worried about your RPMs, if the engine runs well and pulls the plane well let it go at that. I own (2) DLE 30's and have no clue what they turn. I measured them when new just out of curiosity but no longer remember what those readings were. Both engines have run extremely well since day one. One required a timing change as the factory setting was too far advanced.

dear  friends first of all I m reading forum also... I have DLE 30 with NGK CM-6 and I have burned almost 1.5 gallon of gasoline or maybe 2 gallons with stihl HP mineral oil..today I have adjusted needles again and with 19X8 XOAR it has 7100 rpm but as you said above it seems power is good...
1.is this rpm is good or should  I play with needles more? or is it enough for me?
2.sholud I switch to synthetic oil?I have stihl HP 1/2 box more (1200 ml) then  finish 1/2 box of stihl HP mineral oil?
3.should I try 20X8 ?

You will find that when you switch between Stihl mineral oil and Stihl synthetic that you will need to readjust your needle valves.

Why not use up your mineral oil before changing to the Ultra synthetic? So you don't have to be adjusting needle valves all the time.

Dear w8ye thank you..I had read in a thread that breking in process is longer for DLE 30..
so if I m not wrong I will finish my mineral oil..If I m not wrong when we change the mix ratio readjusting of needdles is necessary..then  I  will not change the mix ratio from 1:33 to 1:40?

I have been playing with mine, I have it adjusted where Ithink is GREAT...... of corse with this large propt I reached 8000 today. and it kind of scared me....

it has about 5 tankfulls ran through it now...... As Iread earlyer it gets better with time and fuel.....

Lets face it, what do we want outta these engines ?

8000 is GREATto me. Ihad an issue with breaking the 7400 mark. Only to find Ihad a servo issue.... "DUH"

Iam using the echo synthetic, with shell fuel.


Hope you get yours to where you want it....
