I Dont know if this is a repost or not...but man, DL30 is really powerful!!! check the video that i found on youtube.

Hard to say with the woman's voice in the background

What is the best method to start it cold and hot?

I have read it can be difficult at times.

Also what is the best position for mounting the propeller relative to the piston?


Thanks

I set the prop at the 2 o clock
well as far as starting it took me hours the first
So after flipping my arm off I call Jody at vally view
And was told to turn the idle stop all the way in to speed up the idle
than it was trying to start turned the stop out 1 turn and it fired right up.
hot it would start with out choking it on 1 or 2 flips
cold close the choke flip till it pops open the choke and flip
in the end it ran great
xoar 19X8 bel-ray 7700rpm
I flipped the carb high speed was at 2 1/2 low at 1 1/8

Thanks I will try that. I also flipped my carb and left the gasket and black insulator in it's original place. I check the needle valves as well.

If all goes well today I should have it out flying tomorrow on my new SU26!

OK guys i am in need of some serious specs..

I would like to know the static thrust of this motor with the props in its range.

Thanks in advance

I have no way to test that but I can tell you my new pilot yak at 10 1/2 pounds goes up for ever
and on the ground it ways out pulls anything I have seen

I have seen it turn an Xoar 18x10 at 7500 RPM. The motor has less than a gallon through it and it not turned for peak power. It's in a TLT yak and it has unlimited vertical. I weighed it but I can remember exactly but it was around 11.5 LBS with fuel. It's not my plane but I have flown it although I did not rag it out. I pulled it into a hover at 50 feet and was able to power out and it's still running rich. Someone else has the same plane with an OS 160FX and it is no comparison. I have flown both and the DLE30 is way stronger. I have a new DLE30 going on my SU26.

I did a static test with my SPE 43 turning a 20x10 prop, I used a digital fish scale, tied one end to the tail of my Peak yak and the other end staked to the ground. The result was 17.8 lbs of pull. My plane tops the scale at 12.5 Lbs RTF.

I have spent the last hour comparing raw numbers from about 12 different motors, ranging between 26 and 50 cc. It appears my SPE 43 is little lite on power compared to others in its class. It appears from the numbers i have collected that the DL 30 has more raw power than my 43.

I found a post on the DL 30 that stated it has 18.7 pounds of thrust but they didnt specify what prop it was turning. This motor sounds like a great fit for my new Pacific Aero Gee Bee Y 120.

The flying weight of this plane is listed at 15 lbs. What do you guys think of this combination?

I am sick of glow and I was wondering whether I could use a dle 30 on my Hangar9 Funtana X100. Would this engine be too heavy and too powerful for the frame? Any suggestions would be appreciated.

I do not think a DlE 30 is too heavy....just be real carefull how much throttle you give it unless going strait up. Keep speeds down to prevent flutter. Also you can beef up firewall ect. Capt,n

I had Zenoah G20EI on my Funtana 100 , it's 5+oz heavier than the DLE30. ......beef'd up the motor box and sealed all gaps at the wing's and tail.
And like Capt,n said Full power only going up.

Thank you gentlemen for your sound recommendations.

The aileron and elevator hinge gaps are already sealed with transparent monokote. I'll beef up the motor box and also be extremely aware of not going at high speeds.

I will put an order for a dle 30 tomorrow first thing in am.

boex, go for it! I had a Funtana x100 with 26cc gasser, it was a little lack of power, but good flyer. It almost impossible to balance Fx100 with nitro engine without adding nose ballast, but small gas engine fits like a glove. DL-30 will be a good choise.
And that is true, speed kills. Fx100 has a weak feathers. Landing gear also would be a problem, you wouldn't have any ground clearens with 18-19" props. Mine had a custom alum LG.
Another tip - you have to beef and enlarge motor box. DLE-30 has only 130mm distance from firewall to prop.
Good luck!

On a Gee Bee Y 120 , with an estimated flyng weight of 15 lbs. Do you think the DL 30 would be a good fit?

Thanks

The DLE 30 may fit in the G BEE, but it would snap in a heartbeat if you hit the throttle any to much at all...like at slower sdeeds. Why take a chance....put the engine in something else for several months. Then if you still want to take a chance...try it. Capt,n

Gee Bee Y's are a sweet flying aircraft. IMHO it would be a great combination with all that wing span.
John

captinjohn can you expand on your statement above! I am not sure I understand where your coming from

Thanks

If your Ge Bee is not a true scale race model....disregard my statement. Go ahead and punch the throttle and climb out, if the landing don,t look right. I guess I will keep my mouth shut.....its a waste of my time .....you know after years of trying to help....I am just wasting my and others peopls time

Thanks Vadim for your advice as well. Yes, I concur the X100 is a very fragile bird. I've taken some measures, however, like installing Nylon hinges instead of the CA type provided and sealed the hinge gaps as mentioned above, all to help prevent flutter.

I plan to use synthetic oil from the get-go (Motul 800) and I already have a 19x8 Jxf prop. I'll use a voltage regulator with a 1200 mAH lipo for ignition.

Also, it would be important in my opinion, to have a very fast throttle servo to do 3d with more control. I am not sure whether to go with an analog or digital.

I'll report back as soon as I have flown the tana with the DLE 30.

Anyone else having problem of too high idle speed?

Engine runs very well from 2600 rpm to full throttle. Fantastic performance in my AeroWorks 125.
However, when adjusting Idle down to 1900 rpm (which is a speed that will hold the plane on grass) it will die after
about 3 minutes. Very frustrating as it quits just after making turn to flight line and again after landing.

Have experminented with props from 18x10 to 20x8 and adjusted the low needle for seemingly hours.
In every case, the nice steady idle of around 1900 rpm lasts for only 3 to 4 minutes. Then dies.

Last session, opened the low needle from recommended 1 1/4 turns to over 2 1/4 turns in small increments
with same result. My DLE-55 would go pig rich with that much adjustment. Again, mid range and full throttle
are very good and never dies whilst in the air when doing lots of throttle off IMAC maneuvers.

Any thoughts would be appreciated.

Hi Larry

How much running time has the engine had?

The idle on mine improved significantly after about an hours running time.

I have now got over 2 hours flying time ( ~ 15 x 10~12 minute flights) on the engine and idle is good.

Has 19/8 JXF Laminated Wood Prop, no spinner or anything. Everything stock, except NGK plug instead of DLone.

Cheers

Scott

I agree with Scott:
Break-Ã*n time will seat the cylinder-ring fit and improves performance in many aspects (starting, idle , response, top rpm ...
Mine has about 10 hours of running time and idles well.
I've tested for a local hobby magazine and the results with MenzS propellers is :

18x8 8.350
19x8 7.330
20x6 7.230

All numbers are taken with the RCEXL mini-tach attached to ignition.

WHAT AWESOME ENGINE ........

Regards

Captin,
It is not a GeeBee Z or R but a Y. The Y was not the GeeBee Racer although it was raced. Look at this 3 view. I meant no disrespect just thought you had confused the different models.
John

EDIT The R is the first 3 View. The Y the 2nd.

Well fellas, I ordered the motor. I payed 340 bucks plus shipping, that is what you pay down here in Argentina. You make less money and you pay more, love socialism. Anyways, no more glow stuff for me. Hate all that oil and gooey mess. I can't wait to receive the engine.
