Well ... it seems to me that we are discussing the DLE 30 and what prop is good for your personal application...

but as for me... great post and a bunch of good information... thanks...

Great Post. I went ahead and took the plunge on replacing my OS with the DLE without being able to find data like this. The only thing now is I wish you had a MLD 35 to do the same tests with to round out what were my choices ;-)

Looks like I can stay lighter with less vibration and noise...

But the fuel savings is tempting...

If DLE makes a 40cc I'm in...

Status: offline 		Soo guys how low is to low?

I put a dle 30cc in my Spitfire (71in wing) I was going to put the OS 1.60 as I really want this big bird to screem, I got plenty of 3d Birds, I just want something cool/fast.

Im getting 8300 on a Zinger Pro 18X8, 

I see that most are running around  (Xoar   18x10       7500rmp)

So I was thinking of useing a Zinger pro 18X12, for more speed. I have a plug in tac comeing in the mail, I just don't want to burn this lovely motor up, so I want to make sure its not over prop, so What RPM would you consider to much load?  7000rpm???


I see that BCCHI is getting (Zinger Pro.22x6 6700 rpm

This seems to be the lowest RPM recorder, SO would this be safe?

Also I have never been able to fig,

If the 18X10 dose 7500 rpm
and a 18X12 dos lets say 6700 rpm, wich will be faster?






Thanks Mike

Status: offline 		Well Prop Data, I had a nice 18X14 laying around and I just had to see if the DLE 30 could swing it.

I belive this is to much prop for this motor.  Zinger Pro 18X14 = 5800 rpm 

The motor is still breaking in, its only got 1/2 gallon at most.

The crazy thing is, I put the same prop on a cheap 52cc motor and only got 6300 rpms.  So I can say this DLE is a power house in my book!!!


PS I just want to add the RPM may be a little low due to the fact after I did this test, later that day I was wipeing her down, and found the spark plug was very lose.

Status: offline 		DLE 30V2 , pitts muffler, 7150RPM - APC 19X8W. 2gallons runtime on a Peakmodels Yak 55.
Unlimited vertical but slow spoolup.
Will wait to finetune the engine as it breaks in and if spoolup remains slow... any suggestions?

I also have owned an OS 160 run with a perry pump.
3years of flying on a QQ 73" all I can say is that peformance is directly comparable to the DLE (APC 18X8W@8.300rpm).
Was a Vgood engine but when U go gas there is no return -at least for me.

I need to attach a scale to the plane and weigh the thrust as this combination pulls really hard and should work out great on my 1/4 Fokker DRI. I will be running the engine again in a little while and I will check the thrust.

Thats a pretty heavy prop load for the 30. I would think the engine would be happier with a 20-6 or something similar and that would fit the DR1 airspeed envelope well also.

I settled on the 19-6 for my CUB also. Either Beechwood or the laminated version work the same. Plenty of power for knife edge loops, etc. ...... I know not scale like but oh well!!! More pitch for lighter weight aerobatic planes seems in order and there a 19-8 works well. Nothing really new to report I guess! I continue to enjoy the 30s I own very much.

I think you are right but it is what I have. If I bust this prop I will get a 20x6 next. I just ran the engine again and it has 16lbs of thrust. The DRI weighs 15.5lbs dry. I am sure the engine will unload some in the air so I don't think the prop is going to hurt much and I am also going to be flying at 1/2 throttle or less most of the time. I am guessing normal cruise will be at 1/4-1/3 throttle.
Later!!

Status: offline 		I put the maiden flight on my DRI last Thursday. The plane flew very well with this engine. The engine however did not unload as I had anticipated. I swaped out the 20x8 prop for a 18x8 Xoar Beechwood prop and it seems much happier. It is pulling 7500rpm. I will fly this combination next weekend if the weather will allow and see how it performs. With the 20x8 the engine sputtered on the vertical line of a loop for just a moment. I just ran the 18x8 and held the fuse vertical for a bit and it didn't change RPM.
Later!!

Status: offline 		DLE 30v2 50 degrees, sea level, Installed in 70 inch wing span BH FW190.

Master Airscrew Classic 18-8 8,450 rpm good vertical, good speed (2 blade)

Biela Three Blade 17-10 6,000 rpm, level speed good but very limited vertical.

I think the Biela Three Blade 17-10 is too much prop. I'm going to try a Xoar 18-8 Three Blade as that is what Valley View RC recommends for a DLE 30 in this size warbird. The plane is light for a warbird this size, 12.4 lbs dry. The 18-8 two blade gives it more than enough thrust but I think the rpm is too high when unloaded. I have ordered the 18-8 three blade for Valley View and will report my findings.
