were can you get lawboy ashless oil from , also did you mount the fuel tank on its side? , I don't understant that in the instrutions, am planning two use a canister system

thanks

I am using penzoil 2 cycle air cooled....I built a platform and mounted the fuel tank below the wing tub.

I just finished running my first 4 gallons through my DA, and then switched to amsoil. Man, either I tuned it wrong before, but my performance is absolutely ballistic now

I can't mount below the wing tube because am using a canister system, any other suggestions

Josh,

Did you retune the engine or did the oil make that much difference? I've got about 6 gallons through mine on penzoil.....I'm going to have to get some amsoil

BoneDoc

My Feedback: (1)

after I changed the oil, I leaned it out a little, maybe 1/4 - 3/8 turn. My tach wasn't working properly, so I didn't venture out any further. If I remember correctly though, it was spooling faster already before I leaned it out some more.

Hey guys, I did some more maintenance today since I'm at around 50 flights or so with this bird, and I found that
1. the sock was loose - I re-epoxied it
2. the front part of the fuselage had came off from the front most former.

So, a word of caution to everyone, that white glue sucks Make sure that every 20-30 flights, you take a good look at your bird, and see what else needs re-epoxying .

tIANci

The Extra 260 still has hints of that white glue stuff, it only on the ShowTime that we see more liberal use of epoxy, eventhough it smears but for an ARF aren't we all glad to see it? Hehehe ...

My DA 50 seemed to have "woke up" as well. I thought It was performing awesome until I switched to AMSOIL (50:1) tweaked a little, and WOW! It's like I switched to Hi-Test.

All you guys out there w/ DA-50's, H9 recommeded a 23/8 Meijlik prop. I have tried this prop, a Menz 22/10, and a 3W 22/10. I have found that the Meijlik 23/8 hovered my 260 at 1/3 throttle, but the throttle response was sluggish at the lower RPM's. Both the 22/10's performed great and hovering was at half throttle, but throttle response was much crisper and faster at half throttle. I haven't tried the 23/8 since I switched to AMSOIL. Just wanted some y'all's input.

Try the mejlik now, I bet it'll be even better. However though, I'm already happy with the 22x8 Pro Zinger. I think if you move up to Mejlik, it's just not as much fun hovering at such low throttle setting.

Also for the Amsoil, even though it says 100:1, I used roughly 64:1 (2 Oz for every gallon).

My OS 1.60FX Turns an APC 18x8W @ 8300 on 15%.

While we out flying the other day a friend of mine, just for kicks, tried a Zinger 20X6 on his OS 1.60. The plane involved was a Hyde CapX. I would have never believed it but it turned out to be an excellent 3D combination. The engine turned up to 5800 rpm on the ground & performed very well in the air. Hovering was effortless and the power to pull out was unbelievable. That thing really accelerated from a hover! I'm not a 2 stroke guy but I was impressed.

I am thinking a 1.6fx with Menz 20 x6 with the Turbo Jet muffler will pull close to what a M2.1 with zing 20 x8 will pull?

Gor some more flights today, and I'm back to loving this airplane again. I've made headway mixing out my bad tendencies. I the incidence as a bit off, looking at the wing from the back, but I'm too lazy to fix that right now .

Harrier pretty much locks in, and I was pretty comfortable doing it 15' off the deck (that's pretty low for me, because the financial fear factor is still big). I think one of the causes for wingrocking on this bird is the tremendous torque of the DA50. If you're not careful, everytime you throttle up, the airplane will torque to the left a little, so you will just have to keep that in mind.

I fixed the incidence issue and the plane flew a lot better. I am doing a lot of precision work with it now.

I'm going to uploa a couple of pictures showing my radio installation. Total weight with the SAITO 180, still without the Slimline muffler is 11.6lb (5.280kg). I'm probably going to land artound 12.1lb. Should be OK with the extra on board glow and the powerbox!
Can't wait to get her airborn!!

Scott Dilley

My Feedback: (3)

Why did you use a powerbox is a plane of this size? Isn't it just added weight?

BoneDoc

My Feedback: (1)

I second that. Especially with a glow engine, you don't need that extra weight / safety precaution

STG

My Feedback: (26)

I like the way you did the dual switch. With the 180 No problems with balance issues? I was thinking possibly pull pull on the elevator or bell-crank was going to be needed. Man this plane is coming in very light.

This plane looks perfect for a large glow motor. Nice precision, 3D and scale looks with a good color scheme. H9 has a winner here.

Digital servos in tail and wing, consumes lot of power. Wouldn't risc being without power to Rx, so I have a 4.8V to receiver and 6V to digital servos thru the Powerbox. Doesn't add much wait at all considering the benefit. The on-board glow, in contrary, is a luxury I please myself with in order to get nice low rev's on idle as well as not having to fiddle with glowdrivers and stuff when starting the engine.

thedak

My Feedback: (21)

There is no way that is going to balance like that and I can't see it weighing under 12lbs 8ozs with two batteries. I'm not being an ***** but I know what I have and what is weighs. You also don't need a dual battery set up on a 27% plane with 6 servos, digital or not. I have 6 digitals in mine and I see a max pull of about 6.25 amps with all the surfaces stalled which isn't going to happen while flying. Just messing around I see a continuous draw of about 2 - 2.5 amps. One Fromeco 2400mah Li-ion ( 3.3oz ), with a Dean's connector will do the job. Use a Smart-Fly Adjustable Failsafe Regulator/Switch with the Dean's connector for in power and dual leads for out power and you have a solid set up capable of handling the demands of 5 or 6 digitals.

As far as the remote glow starter, that is completely not needed with a Saito 180. I had one of those for years and never had an idle or transition problem and it was inverted. IMO I would rethink your set up if you want any kind of verticle power.

STG - you are now allowed to buy anymore planes! You have too many!!! Is the EF YAk not enough? Hehehehe ... what do you think of a Moki 210 in the Extra 260?

Well I finally maidened mine today. I bought it back in May, and have had NO time to finish it. I finally got a club member to help me out this week and with a little more work I finally flew it this morning.

My setup is a DA-50, 23x8 MSC Prop Amzoil 100:1 mix, the motor IS broken in. I'm taching 6000 RPM's with that prop and can likely get more, but I'll mess with that later. (I just got the motor back from DA with the updated carb.)

My servo's are Hitec 5945's on the elevators and ailerons, and an 8611 push/pull on the rudder in the tail.

I've got a Duralite 2 cell 2800 on the ignition and 4 cell 2800 on the Rx.

I have NO idea what my AUW is, but it sure fly's light. It seems to slow down and land more stably than my WH Extra did. I only flew it twice before the sun was just right to be wrong this morning, but both landings were things of beauty.

I have not rung it out to far yet, but I will eventually. I'm having some intermittent PCM Fail Safe issues to work on though. It range checked fine, but while doing a pretty agressive blender into a knife edge spin the motor just went to idle. Then I had control again and throttled up and flew out of it. I had noticed it on the ground yesterday afternoon and so I tore apart the wiring and redid it and fixed what I was seeing on the ground, but it appears that I've still got a little at times in the air.

I did a few harriers and elevators, the plain with NO mixes just seems to rock gently back and forth and I can fly it all over the field like that. A little mixing and I think that will go away. I did not try any hovers as I'm not happy with the Rx and until I get that figured out, I won't be bringing it down low and slow just yet.

All in all I'm pretty happy with the plane. It sure fly's a LOT lighter than I thought it would. I've even got a 24oz tank in the plane and can fly for 25-30 minutes at a shot I'm guessing, but it still feels light. I do need to bring the CG back some more though.

Sorry for being so long winded... just wanted to report that I'm enjoying this plane so far.

16 ounces will fly the DA 50 for over 30 minutes. I had a servo fail on my WH extra, leaving it wide open until it ran out. I think that 24 is overkill. I am using only a 16, never come within a quarter of a tank of draining it, flying 20 minutes +
