Yes, that is a fusion. Awesome flying airplane.

Is it necessary to use this on your engine? http://www.gohagan.com/pages/customc...r-8-fl-oz.aspx

hey, quick question for jody: Does running avgas affect the warranty of these engines at all? I can get it really easy, and really cheap too. Basically I like the "no smell" characteristics of it and the long shelf life.

FYI... Jtech is offering 20% off of any muffler in stock - today only.

Slight difference in their wording;

"20% off any stock muffler that we offer"

Good only today, up until 11:59pm (their time).

SpinnerRow

Yea you have to watch the wording but when I saw it yesterday, I called and asked it included the wrap around Pitts for the DLE 20 and it does so I ordered one at 12:18 (their time) last night after the Rangers whooped up on the Yanks!

Go Rangers!

With my DLE20cc mounted on an AW PROX260 Freestyle .90 size, I'd get some exhaust mess on the LE of the wing.
So here's one possible fix for that, and it's cheap too!

Haven't test run it yet, so don't yet know of any bad effect(s) if any.
Possibly a 45 degree fitting might be better than this 90 degree.

It's copper plumbing fitting, for 1/2" copper pipe.
You'll need to sand out inside the fitting, and it's a very tight fit!

my DLE 20 arrives tommorrow - now what to put it in......

anyone put one in the funtana 90 ( the old yellow one) or the newer funtana 100 ?????? I know this plane is great on the OS1.20, the DLE is close..... but will it hover with power to spare???

wildnloose

i have a friend who did just that (Yellow F90). He grew tired of breaking it in so he flew it a couple of times (I think 3 times total). He loves it, sold his Saito 125 after the first flight with the 20. He says the Vess 17x6 prop performs the best. He is getting ready to take out the 10oz tank and put in a 6 oz. He said he could fly for about 30 mins with the 10oz tank, and his nerves could not take that much...

I did see all flights, like the way it performed. He ripped the tail off on the last flight (too close to the ground during a harrier).

And, lets put it another way, I prefer glo over gas, and I am considering this engine...

Aero-Works 60-90 - thats the way to go! Hard part is to decide the 260 or 300?
I'm hoping to outfit one of these with a DLE-20 but I'll have to wait and see if I get a year-end bonus before I can afford this.
Looking forward to it.
Where's the best place to get gas accessories such as fuel tank, hand pumps, etc.?

clivemc

thanks! thats just what i have now the yellow 90 with a saito FS 125. I have never been happy with it, so guess i'll have to try the DLE20, 17x6 prop is going to be close to the ground on the std undercarriage but if it spins that as well as everyone says, i suppose it'll be a good combo

You can't go wrong with Tower

For a fuel tank for this DLE20cc, go for an 8 - 10 oz tank.
Also, you'll need a stopper for it designed for use with gasoline. Dubro sells them.

For a hand crank pump designed for gas usage, get an MPi (gas/glow). It has far better internals than many others.

You'll also need Tygon gas fuel line, 1/8" I.D.

As you seem new to gassers, it'll be good fo you to read the following thread here on RCU;

Jim,
Thanks for the info...I am new to gassers...and tired of paying $16-$20 per gallon of glow fuel.
So I'm trying to plan out my foray into gas power...listing all the stuff I'll need and finding the best place to get it.
I'll check out that other thread...I've read many threads on gas power already...what can it hurt to read another one? <g>
Sincerely,
Mike

[Prop Data]:

APC Sport 16x7 9000 RPM 14lbs. 7oz.
JXF Beech 16x8 8300 13lbs. 10oz.
JXF Beech 17x7 7970 13lbs. 12oz.
SY 16x8 8500 13lbs. 5oz.
SY 17x8N 8200 14lbs. 9oz.

Vess 17x6 14lb. 8oz. - Great throttle response and crappy tach showed 8549RPM
Vess 17x8 14lb. 0oz. - Great throttle response only slightly less RPM than 17x6
Vess 18x6 14lb. 3oz. - Above average throttle response, may be perfect when fully broken in
Vess 16x8 13lb. 9oz. RPM through the roof (by ear) and instant throttle response spools up like an electric motor!

Zinger 16x8 - stinks, no power, way low on thrust
APC 17x4W 3D prop - decent but the idle transition was terrible, 9700 rpm!
Xoar 16x8 - Good prop but not as much thrust on the high end as the next one...
Xoar 17x6 - Hands down the best prop so far. Great punch out of hover, great top end, improved low end but more to come on this....

[Interesting comments]:

same mount size as OS 1.20

a 20cc is a drop in replacement for .90 to 1.20 size four stroke

more power than a CRRC Pro 26 or a Saito 1.25 (Saito FG-20/gasser)

20cc = 1.20 c.i.
30cc = 1.80 c.i.

Agreed, but who's got all that as cheap as the copper elbow?[sm=72_72.gif]
Then there's the added weight too.

I didn't know about this Mpi pump http://www.troybuiltmodels.com/items/MPIACC224.html I always went with the DU-BRO
kwik-fill.

I've got a MACs 90-1.20 pipe. I'll buy a header and see what I get out of it. If it is stupid power, then I'm going to buy a plane that I can put a pipe on. Hopefully the Ultra Stick 60 will come back into production next spring. It sounds like that is fun plane for the DLE 20.

My Feedback: (1)

It won't effect the warranty until it causes a problem and if enough is used it will eventually cause a problem. From fouled plugs, stuck rings, to lead plating of the cylinder and or piston. 87-89 octane unleaded gas works the best, the "low Lead" contentofavgas hasmuch more lead than the old leaded gas weused to run in our cars.The manual calls for 93 octane but the US is one of thevery fewcountries that use the R+M/2 method of calculating advertised octane numbers, this makesour posted octane numbers 5-8 points lower than the same fuel in most other countries. The 93 octane gas in China for example is approximately equal to our 86-88 octane fuel.

Has anyone tried the DLE 20 on an H9 Hellcat? I have run the Zenoah G-20 on that plane and it flew great. Landings were hot due to heavy weight. DLE 20 looks to be about 12 oz lighter than G-20. Perhaps better match for those that want to run gas.

My Feedback: (7)

Should be a good match!
Will you have good prop-to-ground clearance for a 16-18" prop?


Do understand that when asking if anyone has tried this in such & such a model, that this DLE20cc being so new, we're all venturing into the unknown.

For others contemplating a H9 Hellcat, you'll be waiting for one well after their predicted Feb 2011 restock date......say July?[&o]

I flew mine 2x tonight with the Vess 17-6 and on this sub 8 pound Ultra Stick 60 it is so fun! It uses (literally) about 5 feet of runway, then I pull it straight up and do full rate aileron rolls while accelerating vertically, then do a hammerhead when it started getting small. Another gent at the club has the same plane with an OS 75AX and he is just going wow (he actually said something else)! The 17-6 is really a good match for this engine, huge power, good speed and it slows down nicely for landing. The thing about it is, it just does not use any gas! I now fill it up at home (10oz) and after 2 flights of about 8-10 minutes each with lots of throttle, I had almost 1/2 a tank left! Also after the first flight, it started with one flip of the prop for the 2nd flight, about 30 minutes later. It even idles nicely, I don't know what more you would want from it. I think it would easily pull a a warbird up to 70 inch and make the G20 look like chopped liver. I might get an ESM A-1 Skyraider and would not hesitate to try this DLE20 on it.
