I was expecting at least 19 after hearing other reports. Eqipped as follows: Finished pics. A little too cold to fly just yet (for me anyway).

Slimline smoke pump/tank/hose/check valves, etc.

Status: offline 		Looks great!

I am almost done as well. I still have to buy and install the servos, and I'm currently building three A123 packs for this plane. After reading all of these reports of 19lbs+ the first priority in my build has been keeping the weight off so my build will be like this;

(7) Hitec 5985mg's
(1) Hitec 475 (throttle)
(1) Spektrum AR9100
(1) Desert Aircraft ignition
(3) 1100mah A123 packs (2-rx and 1-ignition)
(1) switch for ignition
-no regulators needed
-no smoke
-throttle trim will act as kill switch
-I will be programming the servos instead of using a matchbox ect.

Hopefully this gets me under 18lbs

I have to say thanks for this great thread to all who have contributed!


Oh yea..... and where do you get that coated kevlar? I like that!


Andrew.

Status: offline 		Sure looks cold up there! And a nice looking plane to.

You should be fine at 19+ pounds... biplanes are all about building up a head of steam and then throwing servos around until it slows down. I'm STILL wating on the 3W 105CS to ship... supposed to be around the end of this week now. I think its been about 3 weeks now. I'll let everyone know if I see a difference between the two motors. I decided to go with the rear-carb version to get a little of the weight back. Its a good bit heavier than the DA50, but its supposed to have 1 1/2 horses more... so if I don't have to add a ton to the tail, it should pay off.

Status: offline 		Dons Hobby Shop is where I buy the coated kevlar by the foot. It is nice. Give them a call at 1-800-972-6273. They can send you packets of eyelets for the ball link ends if you can't find the correct size at the hardware store. Good luck on your under 18 lb quest. I don't think I could shave 1.9 lb + off my plane.

Status: offline 		Well its only a goal, I dont have my heart set on 18lbs... just as light as possible. It seems to me that there is a threshold where power and weight, and wing loading cross paths. You can continue to increase power and weight, but its not going to get you a plane that will have the oomph to pull you out of trouble as much as a plane that gets you IN to trouble. Well for me anyways. I usally fly a quick pattern but its not long before I want to be mushing around in high alpha. I hope this airframe doesnt allow me to show how bad I really am!

Thank for the 20 on the kevlar, looks like neat stuff!

Status: offline 		I was especially glad to find that the nose moment is long enough on this plane that it didn't wind up tail heavy. However, with a 3W that is a bit heavier than the D/A it may end up nose heavy. That isn't near as hard as fixing the tail heavy problem. Looks like a break in the weather is coming Sunday. It may be close to 60! I will take the opportunity to run my engine and set up my smoke pump ATV. At that point I will be ready to fly.

Status: offline 		Well, I have officially maidened my bird! Just a few minutes ago in my back yard at 6:00p.m. I assembled the beast and fueled her. Put just a 1/4 tank of smoke fluid in it and did a functional/directional check of all control surfaces. Had my 14 yr. old son/helper hold on to the plane as I warmed up the D/A which is still running rich at the factory settings as it only has about 10 flights on it with a 16 oz. tank when it was in my Yak. It ran great, but rich in mid range. It was about 36 degrees out and calm with a slight breeze out of the east so I headed into the breeze and slowly accelerated through the grass that is my back yard. (9 acres with about 400 acres of Govt. Corps of Engineer land adjacent to it) At about half throttle the 20 plus pound plane lifted easily off the ground with very light elevator pressure. With the balance point at 2.5" aft of the upper wing L.E. at the wing tips it flew light and required absolutely 0 trim on any surface. I did a few knife edge figure eights on low rate then took it up and put all high rates on and flat spun the beejeepers out of it. Had to eese off of the ailerons a bit to get a great flat spin out of it. Knife was very neutral with only the slightest hint of roll couple and pull toward canopy or gear was nill. For a plane as heavy as it is it flies really light on the controls. Since the darkness was coming on fast and my fingers were starting to numb, I pulled the throttle back on down wind and hooked it around base and onto short final. It slowed down magnificently and I had great pitdh control which tells me that the c.g. is close to where I like it. Nice slow aproach and a gentle flare and a perfect three point landing and kill the throttle trim and it came to a nice short stop in the slightly soft permafrost grass. I am thrilled and look forward to more flying in the near future. Now if the weather will just cooperate. YEEEEEHHAAAAWWWWW!!!!!! The design team did a great job on this one.

Status: offline 		Thanks, I plan to excercise this one a lot this summer. Now on to the Goldberg Monster that is currently waiting patiently on the bench. Just need to install the tanks and plumbing plus all batteries. 29cc goped conversion. Should be a neat plane also. The fuse is just as fat as the Python but control surfaces are tons smaller. I like its really round fuse all the way aft past the aft wing saddle. We are possibly in for more snow and 10 degree weather in the next few days. Glad I got a break and got to fly the Python. Lets get some more of these up in the air. I know they are out there. Post your progress and please ask any questions or if you need pics I got em.

I guess I understand now why DA seems to have the single-cylinder market wrapped up.. 3W (or their dealer) just doesn't care.

Status: offline 		I will be curious to see how the C.G. is affected by the 3W 55. My Python appears to be balanced perfect for my flying style and taste. I need to program the cnditions on my 9303 so I can have 3D throws on one switch. Then I can flip it on and off instead of all three switches. Haven't played with that feature as of yet on my 2.4 9303.
