Bobby of Maui, A new friend has given my 75 in Stik it's maiden.I have a RC Areo 20 cc & it ran like a gem with plenty of power for the 14 lb plane.
How do I add a photo?

It is funny how things change. I always used to overpower my models, partly because I lived at 4500' elevation which kills about 15 to 20 percent of your power right there. (depending too on temperature.) I used to run .25 engines on .15 planes, .40/.45 engines on .25 planes, and .60 engines on .40 size planes, etc. Back then, everyone thought I was crazy. Nowadays, everyone would think those planes were a bit underpowered!!

A gas engine with it's relatively big prop turning slower is more efficient than a small prop going like a bat out of hell like on a glow engine. I think in most cases a 20cc engine on a 90/120 size plane is a killer, powerful combo, and on a .60 size plane is just incredible! I once kit bashed a .60 size Stik to a low winger, shortened the nose a bit, and put a 25cc gasser on it. I had great fun with it for a long time, then sold it to a friend and it is his favorite plane. It is fun to see it accelerate going straight up until it is just a dot in the sky, then spin it back down....

I only have one glow plane left. It is a Twist 40 with an old Fox .78 on it. Now there's a fun combo too! Cruising by at half throttle, when you nail it, it accelerates like it is going to leave the tail behind!! A Twist .90 (60?) with a DLE 20 on it would probably be pretty cool as well.

Help !!! Has anyone purchased or tried to buy a DLE 35ra engine from AEROBEEZ HOBBIES within the last 6 weeks. I had one on backorder for the last six weeks and as of today the engine is still on backorder. They seemed to have quite a few of thier products on backorder. Are they going out of business? The engine in question was purchased with a 30cc airplane and I got it for a great combo price. I finished assembling the aircrsft, now, I need the engine, to finish this project.
Iknow that this is a DLE-20 thread but I need help and I didn't know where else to go.
I guess that I can cancell the order but I have to pay more for the engine plus frieght except from Chief Aircraft. Please help.

Put a stop payment request on the credit card. That will get their attention.

I installed one in a Seagull Edge 540 -120 size.... All I can say is ... WOW!!!... Fly's GREAT.... Been looking for a good match for the DLE20 and I just found it..

bmitc64991

does any one know if a dle-20 will fly a pt-19 78" wing span ok, plain is about 8-1/2 lbs with-out engine and batterys also the gc in the book says 105-110 mm back from the leading edge not sure about that does anyone know if this is the correct gc for a pt-19 I read somewere were some one said just go 5'' and it would fly just great just not sure,

kmeyers

Maidens are almost always successful at 25% of the wing.
25% is easy to find on anything except a swept wing.
After the maiden you can move it to suit yourself.

stevegauth30

I would agree with kmeyers. 25 to 27% of the wing chord! back from the LE. I would think the 20 would fly that plane with plenty to spare. Especially that type of plane. Good luck with the maiden.

thanks kmeyers, and stevegauth for the reply, the engine should back from the factory next week i'll go with the 25-27 % of my wing for the gc (should I balance my pt-19 up side down) the manual does not say.

stevegauth30

I've always balanced my bipes right side up on the top wing, with good results, but wait and see what others say too. I don't want to lead you in the wrong direction. That's just my experience. Steve.

raptureboy

The Pt- 19 is a low wing plane usually balanced upside down, the Pt- 17 is the Stearman bipe. What brand of plane is it? you can go to most manufacturers websites and get the CG info but if the wing is a constant chord wing then 25-27 % will work measured at the root. I have a 20 in my PT-17 at 14lbs and 1 in my Ryan at 11lbs and also in my 60 size warbirds. All fly with plenty of power, especially the warbirds

stevegauth30

Oh sorry, I thought it was a bipe. See, here I go, leading you in the wrong direction. Lol.sorry.

bmitc64991

thanks rptureboy for the pt-19 info, it should come in under 11 lb so ill go ahead with my dle-20 everthing including the servos less engine so far is right now is less than 9 lbs I only need to add the weight of the dle-20 and battery packs when my engine comes back from the factory if they ever get the part in

twin astir

I have two Dle 20 installed on my Gotha GIVa. 19 kg and 4 m wingspan. Very realiable and moré than enough power.

bmitc64991

raptreboy on your pt-19 did you balance at 5" or go to 6" from the leading edge ?

CustomPC

I have one of the new DL-20RA rear exhaust engines and will be putting into a Hangar 9 BF-109.

It should be a good match because by all reports the model still needs a pound of lead up front with a Saito 1.25 so the extra weight of the DLE plus ign and battery should help there.

tazz05

I have an extra 260 and I was thinking about putting one of these on my plane. Is there anything that I need to do to install this engine on this plane. And what do you think about a DLE 30 is that to much for this plane.
thanks guys for any input.

1300rpm

What is the size and weight of the extra 260?

I have a few DLE20.
Lovely motor, reliable with good performance, run in on 16X8 Xoar prop, once run in done replaced by 17X6 Xoar, all use a mounting plate available from Seaplane Supply (link below)
http://www.seaplanesupply.com/aluminum.htm
the mounting plate matches DLE 20 to DLE 30 mounting points thus, if the 20 is not enough you can replace it with the 30 without the need to make new holes.
You will need to use stand off's, the lenght will depend on the space available from the engine box to the cowl

You will also need to replace the throttle lever with one CNC Alloy Throttle Arm for Gas Engines

The 20 is enough power for a 14lbs plane? Do you need to fly at full throttle? I'm building a 84" ws Fly Baby that should weigh in around 11 to 12lbs. The plans calls for a 1.20 4 cycle. Do you think the 20 would be enough for mild aerobatics and casual flying? I'm trying to decide between the 20 and the 30.
Thanks.

kmeyers

With the right prop the 20 will hover a 14 lb plane. The 20 has more power then the average 120 4 stroke glow and about the same as a 120 2 stroke glow.

How much drag and the wing loading is whether or not you would have to fly at full throttle, so probably not. As a matter of fact I would bet you could fly that scale like with an OS 60 glow. But the 20 gasser will be more fun.

I have 2 of the 20's. I kind of use 11-12 lb as the cut-off for the switch to the 30. Because mild is not enough power for me.

drube

Don't know anything about hovering. lol So you're saying I should go with the 30 because of the 11-12 lb weight?

kmeyers

No not for mild flying. The 20 would be 1.2 to 1 ratio on your plane. I like WILD power to wieght ratio 2 to 1 is perfect for me.

Without tapered wings and large control surfaces or pylon type drag, the 20 will be just right.

drube

Ok, thanks. So loops and basic aerobatics should be no problem then?
