The 60 size Ultra Stick (if you can find one) flies great with the DLE-20 and mine has zero additional ballast weight. It did require moving the (smaller) tank aft, with the ignition box forward, and has rear mounted rudder and elevator servos. The AUW is 8 pounds. With the 66 inch wing it lands very easily without flaps, and when inverted only requires a little elevator. The smallish 8 oz tank is good for about 20 minutes, but it is best to keep it at least 1/2 full so it does not flame out on a long down line, ask me how I know this!

This was my very first attempt at a gas powered plane. It is a Great Planes Ryan STA with the DLE 20. It's maiden flight was today, Feb. 26, 2011. Only required one click of down trim. It was a very uneventful, low stress flight, which I give full credit to all the great posts on this forum, filled with good information. I flew it 4 more times after that with the same result. My interest in the hobby has been renewed after 30+ years. Thanks to all.

Congrats mcandies........Glad you are back. I really like the looks of your plane. It reminds me of the old Sig Astro Hog. I built one of those back in the early 90's

It was about that long for me as well, and the Syssa 30, and the DE-20 got me back into it! Now I have only electric and gassers, no glow slimers.

Ooh, I was still active and flying, just seems like there wasn't anymore excitement flying the .25 to .91 nitros. Too much equipment, mess, cleaning, and too finicky!

Beautiful job on the Great Planes Ryan STA.   I noticed that you even painted the exposed muffler white to match the outiside surface.  Looks like a good fit for DLE 20cc sizewise.  The Ryan STA has a pretty long wingspan of 80 inches and a fairly low wing loading at 10-11 lbs.  You did not say anything about the performance.  

Enjoy.

The .60 Ultra Stick looks like a fairly tight but reasonable fit with the DLE 20cc.  Using the one that Horizon Hobby used to sell, it has a very light wing loading.  It must really scream with the DLE 20cc.  I do like the exposed engine, which would make it very user friendly.   I also note from your photo that you did a nice joy with the components to help with the CG. 

Thanks for sharing and enjoy.

Well I had the engine a little rich and max RPMs were in the 7400 range with a Xoar 17" x 7". I also had the control throws set pretty soft. It lifted off of the concrete runway in about 25', (surprised me), flew out straight and level. Turns were very smooth and easy. I have to admit it took a little getting used to landing it. The largest planes that I had flown were .46s. At the end of the day I removed the cowl and did some tuning. Got the RPMs up to 8200 then backed down, (with the high speed needle), to 8100. I have a 17" x 6" Xoar to put on it next time. It flies slow and easy with no bad tendencies. I expected this to be a good plane to try my hand at gas and it didn't disappoint.

PS: Yes I painted the muffler with hi temp header paint. Just thought it might be less noticeable in the cutout.

Jonde,
Like you, I am moving towards larger models...my most recent purchase was a 68" Su-26m with a DLE-30. I'm hoping it will be easier to see for my aging eyes. Don't worry about asking questions...I've certainly asked my share...and most of the people on this forum are willing to help. I've even asked questions that have been answered before, and I'm still alive to tell about it <g>. The intended point of my previous post was more around the idea that more information about your flying goals was needed before your question could be adequately answered. What airplanes are you considering for your DLE-20? Are you a warbird guy, or sport or ?
Best regards,
Mike

Thanks for the practical advice. I guess I got the cart in front of the horse. I just started with this web site and forum so I just kind of jumpted in. I have taken your advice. Reading the collective history of this forum first makes a lot of sense. I will try to reserve my questions to the, as yet, unanswered or unresolved specific issues.


Thanks again,

My understanding is that the correct timing is 28deg before TDC.

It is very fast, even with a Vess 17-6 which gives it screaming vertical performance. It is a blast to fly, and I have about 45 flights on it, including 3 recently on skis. It is kinda my beater plane, and I have better planes, but it is like an old friend that maybe is not a 3D monster like my Extra and MX2, but is alot of fun to go fast, especially straight up! I have a spare NIB wing and fuse in case I total it. If you can get one, the US60 is a perfect fit for the DLE-20, and as you say,very user friendly I did almost shear the wing pins in the front, so I changed them to some carbon ones. The 90 MPH snap rolls are what almost killed it.

Thanks for all the flight infomation on your big Ryan STA.  Sounds like really scoots with the DLE 20cc.  Did you consider going down an inch in prop size and up a bit in pitch to give you a little better speed control on take-offs and landings?  Just a thought.

I appreciate your kind comments.  I have mostly flown sport planes.  My latest purchase was the Hanger 9 Toledo Special.  I had a OS .55AX in it and went to a OS.46AX.  In my opinion, it is way to light for the DLE 20cc even if it has a 70" wingspan.  I really don't have a particular plane in mind yet.  I like the Ryan STA that Mcandies just reported on or even a .90-1.20 size Ultra Stick.  I do have an old Spitfire with a 63 span which weighs about 9 lbs, and might be a fit.  I'm really thinking about something that would be a good fit with the DLE 20cc as my first gasser.  I'm thinking, keep it simple! 

regards,

If you can find one, a Rascal 110 ARF would be just right for some leisurely flying. That's what I am going to put my DLE20 in.

I really got a great chuckle from your comments about the 90mph snap rolls and almost shearing off the wing pins, and then looking at your photo's.  You have given me a new prespective as the new guy looking at going to a DLE 20cc gasser...   I think you have defined one end of the flight envelope. 

Thanks, and keep having a blast.

You may have hit the nail on the head.  The Sig Rascal 110 looks like the perfect match for the DLE 20cc engine if you want some comfortable flying.  It's certainly big and would be easy to see, and at 11-13 lbs AUW the DLE 20cc engine would seem just right from what I have read.  As a bonus, there has to be a ton of room for the flight gear. 

Thanks Mike

Jonde you're welcome, but don't thank me so fast. You have to find one. SIG is out of stock, so is most of the on line hobby shops. I hope you get lucky and find one. I have had mine in the box for almost a year. Just have not got to it yet. I was going to put a Zenoah 26 converted by Ralph Cunningham to electronic Ignition, but this DLE20 has a great weight savings and probably more power to boot. I'm glad I waited. Maybe some kind soul on one of the RCUniverse forums has one for sale?????

If you're looking for one, go to RCU's classifieds and do a search on; Sig Rascal 110
There's several listed right now.

Mschulz531(Mike) - I see that you're going to install a DLE30 into your new 68" Sukhoi SU26. This past weekend I picked up a slightly- used CG 72" Sukhoi SU26, plus an extra set of wings and wingtube, for a great price. It's a beautiful looking plane, and everything I read about it's performance sounds excellent. And I already have a DLE30 NIB (just waiting for the right plane...), so I think it'll be a perfect fit - and my first 3D plane! I'm interested in how your build \ flying goes. Mine may have to wait for a bit - have a few other projects in-line before that one. Plus I need to save for decent servos!

As far as the DLE20, I have one installed in a GP 70" Revolver. That planes' recommended high end engine is a 91, so the DLE20 is a bit of a tight fit. Had to cut out the joining bars of the plastic engine mount, and move the tank back, and shift two of the blind-nuts out, but it does fit. I love the power combined with the fuel economy. I think it's the perfect engine for this plane.

I sent an email to Sig and asked when they expect to get some Rascal 110's in stock again.  If I hear back, I will let the group know.  I am in no big hurry so I don't mind a reasonable wait.

You are right about the Rascal 110 not  being available.  I emailed Sig and this was their response:

We are experiencing serious problems with the supplier in China.Consequently, we do not anticipate that we will be receiving any ARF kits orARF kit parts in the foreseeable future. Should that situation change, wewill place a notice to that affect on our web site to let everyone know theyare available again.Right now we are working with a new supplier in China and hope to come to anagreement with them in the very near future.We are sorry we couldn't give you better news at least for now.Does not sound too good.  The one's available on RCU's classifieds are all RTF models with various flight packs.
Will keep looking.
