These pictures refer to the pipe install.
Everything fits nice and tidy. The extensions are just a bit crooked but that's ok. The fuse spars won't quite let them be straight. The KS mounts are super cool and nice. They are rubber mounted so to absorb vibration.

I'm still debating on how much area to leave open for air flow exit...but I think I'll recover some of the area. I had to open it up to get to the mounts.

The last picture is the 9=7950 servo and the 4.5" arm that will go on it.

Thanks
Barry

I also think I'm going to build a front mount for the pipe header connection to support on the front end. These are long heavy pipes. Still working that out in my mind,,,,,what's left of it.
Thanks
Barry

did you say the pipes were 1.5 each or so, adding 3lbs to the plane then, im just curious, considered it myself...
does anyone have numbers on a prop with stock mufflers and then pipes?? id love to hear what you actually gain, i think i heard 150-200 one time, that doenst seem like very much to add 3 lbs and the cost and setup time, but i heard 500 once somewhere, that would be worth it, anyway id love to hear actual gains if anyone has them

Yep, they weigh about 1.5lbs each. But, they are only 1 oz heavier each than my canister set up. The header actually weighs more than the pipe itself. However, remember, your exhaust will probably weigh 1/2lbs each, so the net is only 2lbs. Still, a lot of weight. I do it because our field likes quiet planes and I gotta say I like the sound of the pipes and I like the quiet too. My personal experience on 50cc engines that they have more thurst with stock exhaust than with canisters. But they are very loud with stock exhaust. Not much more thurst but a little. So the canister is bad, it adds weight and reduces power a little. But it does give a little more midrange. So it's a different kind of power that you can feel. Many may think that is more power...but it's not. My trusty fish scale (thrust meter) tells me there is less thrust with a canister.

I was getting about 42lbs thrust on this same engine on my canister set up. I never ran the engine on the stock exhaust, but I was getting 42lbs on the canisters. I'll let you know in a day or two exactly what I get with the pipes. I'll measure the RPM but a better measurement in my mind is thrust. I've had situations where I spin higher RPM with smaller props but don't get the thrust. So, to me thurst is a better measurement. I'm thinking of returning to the 26x10 prop instead of the 27A Vess. My best thrust was with the 27A but I got about 40.5 with the 26x10 and I thought it was better in the midrange. But I'll start with the 27A just to compare to see what the real advantage is with pipes. I've always been a bit nervous with pipes because I've felt the transition was a littler worse. But, after talking with others and directly with DA they tell me it's easily tuned with th MTW pipes. And I think you said you flew someone's plane that performed well with pipes. So...I'm gonna try a set on this plane. I was going to run canisters anyways so I don't have hardly any extra weight but if I get a nice performance boost....then that'll really help.

One clue that may help....I built a AeroWorks Yak with a DA 50 with a pipe on it. I was getting about 22.5lbs thurst on a DA 50 with a canister set up. On the same prop and with the pipe it went up to 25lbs thrust. I flew the plane exactly once and gave it to a friend so I didn't get to test it at all. He's let me fly it since one time and I was pretty impressed with it and I didn't have any problems hovering the plane. I actually thought it might be pretty good. Using the same formula on the 100CC DA, I'd expect to get about 5lbs more thrust. That would be a very nice increase. And you would only be adding 2lbs to the plane in your case....in mine 1oz. So they very well might be worth it. Worth it but expensive.

Anyways, I hope to maybe even run mine by tonight. The DA is broken in with about 60 or so flights so I don't have to baby it. I do all my thrust testing here at my house in the front driveway. That way I'm pretty consistant and uniform. I'll know pretty quick exactly how much more thurst I get. Should be very interesting.

thanks

cool id like to hear the results, and i dont think my stock exhaust is 1/2lb each, i dont remember if i weighed them, they are the silent beaty from tbm, they say 9oz on there site i believe thats for both, they felt very light when i mounted them, not much to them, so id be adding more weight than if i had cans already, let us know your numbers, im using the same props you are, 27A and just put my mej 26-10 back on yesterday to try since my move, i got to say it worked out better than i remember in arizona, pulled out just about as good as the vess and was quicker in flight, its staying on for now, we'll see when it gets hot again next summer if it strugles at all pulling out, thats when i noticed it in az, hot summer time with thin air. i was getting around 6700 with the mej, that was after a few flights so i know it was accurate, always get higher readings if you tack it before 1st flight before everything is hot, my biela tacked abour 63-64, it was noticably slower in flight and pulling out, bummer cause when running that yellow line appears and looks awesome, just doenst work for my set up, really like the biela on my single 80cc, not as big of a drop from the mej and pulled better, so now my mej is on and my 27A will be waiting in the bag till i see any drop in performance, not sure i may list the biela on the market, or hang on to it and if pipes increase the motor enough to tourn the biela as good as the mej it would work great, btw the mej looks cooler when stopped

Barry,

Really glad to hear about all of the progress both with the plane and with the healing. It sounds like it is all coming together for you. Looking forward to hearing about how the single 400 ounce rudder servo works for you and also on how the thrust of the DA 100 looks with the MTW pipes. Best of luck to ya and I hope that winter holds off long enough for you to get the maiden in.

Still loving my ef 110.. I have had and flown quite a few big birds by now.. 70 something flights later I still believe this is the best flying plane out of all of them, and the best/scale looking yak out of them all. It literally flys like some of the planes on the aerofly simulator.. Here are some shots from this last sunday.

The other Yak is also the same 100cc size correct ? The EF one just looks so much cooler as well as a GIANT compared to the other one!!

The other is a TT TOC 33% yak. He has a da85 on it and HOLY !@#^ it has to much power. It pulls the same as my extreme flight with the da100. The EF 110 still has great power to weight and I am running smoke, the cockpit floor is installed and painted with stone(speckle) finish, and the pilot is in and the plane still flies like it has helium in the wings.. The ef 110's I saw at Joe Nall were almost dwarfing the TT toc 37.5 % yaks as well!!

I originally had the DA 100 with MTW canisters in my first 110" Yak. Chris and I tached it and I was getting around 6300-6350 swinging a Mejzlik 28-10. The plane had great power with that setup, but could use just a touch more if flying higher levels in IMAC. I installed a new DA 100L this year in the new 110 with MTW RE2's swinging the same prop. I tached it and it showed 6750-6800, and man did it bring the plane to life. It seriously feels like a different plane with the pipes, it really makes a big improvement. I've since switched to the Mejzlik 27-10 since it doesn't seem to rip as bad as the 28-10 yet pulls just as hard, and actually seems to maintain speed on verticals after snaps better than the other prop. I haven't tached it with the 27-10 but will the next time I get out and post the results on here. Another thing I really like about the RE2's is the transition, I haven't had to add any throttle curve to manage the pipes, they're very smooth throughout the transition of power.

Still waiting on that call to go fly the 88 and 110 together! It's ready to go - just needs the needles tweaked.

I'm packed and ready to go - sort of! The radio is programmed, plane is together, batteries are charge, nothing left but the hucking - of in my case - the lazy loops, and rolls. Still had to belive I've got one of the original 20 and it's only been in the air for like 3 minutes total flight time. BTW, your welcome for me telling you that you HAD to get the 110"

Been working on mine the last couple of days. Completed the rudder installation and the pull/pull. I went to the inner hole on the rudder horns and with the 4.5" arm I'm only getting to about 3/4" from the elevators. That appears to be about 45* but I don't have a good way of measuring the rudder travel. I was hoping to hit the elevators but I'm sure I've got enough.

I moved my elevator horns to the inner holes also. I'm now getting 55* down (should give me the best shot at inverted flat spins) and 45* up. I get the same on both elevators. If I want more than that I could hog out the wood a bit and get perhaps another 5* on the up swing. For now I'm gonna leave it the way it is.

I've got all the switchs mounted and tested and all the electronics mounted and ready. I haven't mounted the batteries yet because I'm waiting to check the balance.

What I've got left to do: Mount the big wheels and axles, mount the tail wheel, mount the cowl and the blind nuts in the cowl ring, install the baffle plate in the cowl, balance the plane, mount the batteries permantlly, weigh the plane, do some thrust tests and fly. Weather is still holding out here for some reason. I'm thinking Saturday might be a good day.

What do ya say Steve.....you available on Saturday? I'll need help getting the beast out of my home, and loaded in the pick up. Also will need help starting the engine....Would like to fly on my turf for the maiden. Also probably fly the Reactor first since it's been two months since I've flown anything.

Oh BTW...when you get your new canopy....be careful and don't drop it. That's how I broke that one....before I even fly it. Turn the plane sideways to get it through the garage door and the canopy fell off and hit the floor and broke. Anyways....I thought the tape was kinda classy....but hey, a new canopy is nice also.

Anyways....very close now. Looking forward to it.

thanks

I can't wait to fly it iether!!. I'd be glad to help. Saturday looks to be snowy and windy. The next good day looks like Monday. I can make down there Monday also if you want to wait for a nice day. I thinik that is going to be your new favorite plane!!

The new canopy won't go on until Spring!

barry i broke my sd canopy like that once, now i use those canopy covers that ef gives you, i make sure im velcrowed in b4 carrying it anywhere, cost me about $50 for the new plastic and shipping, was an expensive lesson especially since it was new at the time[:@]

Dave,
are those hard plastic, or soft covers?

those silvery bubble wrap type things extreme flight gives with the planes, like there wing bags, i saved the one from my 88 when i sold it so i use that on my sd, are they still giving them with the plane? they did

Barry Cazier

My Feedback: (17)

Steve you're right about the weather. Let's plan on Monday afternoon. That looks to be the best right now.

Dave is talking about the foil covered bubble wrap that comes with the EF planes. I think I have that one that goes over the canopy for your plane. I'll give it to you on Monday. Many use them to shade in sunlight because these canopies are very thin and will warp if you leave them in the hot sun.
Thanks
