Airwizard,good to hear all went well,i forgot to say that i replaced the tires as well,just sitting on the work bench when i was putting mine together it looked like they was crappy so i did throw the stock ones away

Here is the 3D update .....flat spins are ok,,,,,,Inverted flat spins are beautiful......snaps are crisp and no over rotation ......harriers are solid with little wing rock.....knife edge has pull to canopy.

A couple of things I need to tune are.....I like my planes to fly hands off inverted so I need to move my battery back some. I'm using 1.25 SWB servo arms on the rudder and need to get more throw so I'm going to play with the linkages or get longer servo arms. I think these changes will help on hovering and knife edge.

This plane is a keeper.!!!!!!!!!!!!!!!!

Sounds Fantastic!!!!!!

If I didn't have so many other things on the agenda, I'd even get mine put together............

Glad to hear that it's a keeper !!!!!! Keep us informed.........................

Great!

Starting mine this weekend. Any video yet?

badfish

maidened mine today! WOW! lots of fun. I ended up putting alum. on the motorbox corner just incase. DA 85 started right up no problems. was really rich though. tons of pull. I tried leaning the low end but didn't make much difference. next time out I'll try leaning the top end. not tiill almost full throttle did the engine sound like it would run clean. I'm running 26x10 mej. w/tbm muffler. turned 6500 with no needle adjustments.
as theo has mentioned you need to at least add some glue on the cowl mounts. I had one break loose. I added epoxy to 1 side but didn't have the time to do the other. (which had 1 break). the piece of wood that has the nylon in it came out. just need some glue on the corners by the nylon nut.
I also changed the tires. I'm running 4" skykites.
my cg is further back than stock. flys really well there. doing a wall the tail slides past 90' KE was great. very little coupling. inverted flight required a little down elev. landings were very nice. no balloning and was uneffected by the 10-15 mph cross winds. really have to set the idle low as the plane just wanted to keep flying on landings. the 85 seems to pick up speed on uplines. very cool! hanging the plane requires way less than half throttle. in fact it felt like just off idle is what it takes to keep the plane from climbing.
I did add glue to the canopy latches and didn't have any problems.
here are some pics from today. next time out I'll try to get some video.

Welcome to the EXTRA Club Badfish!!!!!!!!!!!!!!!!!!!!!!

davemilw07

NICE flying field, badfish, and NICE airframe !!!!!

Looks like you're only using one aileron servo on each side (I was planning to do the same, as well as one rudder servo). I assume you're using Hitec 5955TG's or equivalent????

I suspect that a DA-85 probably is overkill on this size airframe........I have a 3W-75i that I'll put on mine. What is the AUW of your plane????

badfish

I'm using 8 5955's. 4 on ailerons and 2 on rudder. I wouldn't go with only 2 on the ailerons. they are spread too far apart. If you grab the aileron you can easily twist it. you don't need 55's on the ailerons but I'm sick of replacing servo gears every year on my gassers. its always the ailerons that get beat up. plus they are not much more than the 59's. you should be fine with 1 on the rudder.

22 1/2 lbs. I know my 4" skyllites are heavier. and I'm running dual 2700 nmhd 6v packs for receiver. I changed the tail wheel to a cf one I had laying around but I don't think its much liter. I wasn't worried about the weight on this plane.

the plane feels just right. doesn't fly like a brick at all. landings come in very slow. and with the barn door control surfaces. it does what you want it to do. it should be a great 3d plane. I had the confidence on my second flight to start throwing it around.

well i got mine ready to fly again,and i took off and was making a turn and a guy at the feild said something just came off and i said to myselve now what could be wrong to i brought her in and landed it just fine shut the motor off and went to look

well the covering at the bottom of the fuse was ripped off from the cowl and halfway down the length of the fuse,when my fuel tank stopper came off the gas ate the glue on the covering i am guessing so now i have that to repair,but all in all it flies great i just hope now all the demons are takin care of

so if you are flying with the supplied gas tank i would change that out as well

Sorry about the problems. But thanks much for the info.

davemilw07

Sounds like the stopper screw wasn't tightened down enough..........Or is there a limit to how tight it will go?????

theo63

dave,the stopper screw was just fine,there is just not enough lip on the supplied tank,i did try to reuse it at the field that day but it would not work as it was intended for

Some of the guys at our field are complaining about the ethanol in the gas. It seems like it interacts with some of the material that some fuel tanks are made of and eventually cause crack/leak/failure. If you are runing an inline filter the tip off is the white residue that accumulates before the problem becomes apparent.

Hi I have a 4.2 75CC Sachs Dolmer sitting around and I was thinking of using it when I build my extra 300 94", can I get some opinions how this will work with this plane.
Thanks

I flew my extra this weekend for the first time. It flew perfectly and was very easy to land, only took 2 clicks of elevator trim to get her trimmed out. I did have trouble getting my DA 85 leaned out as was mentioned in an earlier post. I had the high speed needle leaned out to only 3/4 turn from bottoming out and it was still running rich. I stopped there and e-mailed DA about the problem and they suggested venting the box more to possibly equalized pressure behind the fire wall. I havent tried it yet. Has anyone else had this problem. On the ground the motor runs great and in the air runs very rich and leaning the mixture screw doesnt seem to help.

I have a DA85 in mine and haven't had any problems.......My carb is enclosed in a 1 inch wood spacer that opens up into the firewall.

badfish

diggerup. I was playing with my needles the other day. mine too runs rich. I thought for sure it would be the low end. but if I went in too far it would stumble on throttle up. so I played with leaning the high end. I ended up at 6600 rpm and continueing to lean the needle it did not drop off. so it is obviously drawing fuel from elsewhere in the carb. I'm going to play with it some more with the cowl off.

oh, and when in a knife edge or inverted it seems to clear out.

this are my 2 cents, the low speed needle control the rich and lean mixture of the hi speed needle, but the high speed only control the high speed. Hope you understand.
lean the low speed up to the point you troutle repond is erratic doing fast movements up and down, the engine may shoot off, then back up 1/4 to 1/8, now the hight speed needle, do allmost the same, and fly the plane, if the plane spotters close one needle at the time, can be ether the low or the hight that is rich or too lean, or you may have it perfect after you did it on the ground. Good luck. This is a recomendation no a rule. Monty.

My zdz runs perfect but man I end up with the bottom of the airplane painted in black, I use 40:1 that is recomended but still have the black tar in the bottom, but the engine is super reliable so I prefer to clean a plane that replace a plane.

Hey wizz,
on the pull to the canopy try moving weight aroung, either toward the bottom or lust a tad forward and it should have no pull in KE flight.

AirWizard

My Feedback: (3)

Thanks I will try moving stuff around......as soon as the wind dies down (25-30 mph)

GmanBill

My Feedback: (10)

Put that baby nose in to the wind at a 45 and start it rolling, wind is a blast with this plane. I spent many days flying this plane when the wind was high because when Bubba had us working on the prototypes we had no choice, we didn't have but 5 days with no wind in the 30 days we worked on them. The Extra balanced the best with the batteries next to the servos for the Pull-Pull using 2 TBM LiIon 5600mAh square packs one on each side and the ignition battery on the port side of the motor box with your setup.

I was having trouble getting my DA 85 leaned out enough when it was in the air. The solution to my problem was to leave the top off of the engine mounting box. I had it out this weekend and it ran great. The way the air was swirling around in the cowl it must have been pulling air away from the carb.

Just a heads up. I'm probably going to sell my Extra and Yak. Not looking to make a dime from them. I just happened upon a new project. If anyone is interested, the price is exactly what we paid for them. But the buyer will have to sping for shipping. Since these are discontinued, it would be a good idea to have a spare. PM me if interested.

PS. I thought I'd post here first as to give you guys that follow the thread first shot.
