PCM : Erwin XL ultralight

[JYZoom]

Congrats on the maiden. The plane flies sweet. One giant DLG. Extremely bouyant. Awesome to fly in those really dead air days. I think you will enjoy flying this after 6pm when the wind dies down.

Hawkeye, thanks for Pang and yourself watching over me when I put the final touch before maiden. It was create to have a successful maiden. Still need to learn stuff from you and others on fine tuning the glider...e.g. getting a cleaner roll...

regards,
Jonathan

Congrats for maiden flight

Hey Jonathan,

it seems that you have assembled the plane in record speed! Mine is almost finished, fuselage is complete but waiting for the servo frames for the wing. Hope to be ready for the maiden next weekend. How is your weight balance? I use a smaller Kira 400-27 which is 40g less than the 480, but also have mounted the servos in the back.

Scooper,

Thanks for dropping in, while I didn;t post I follow your thread quite a bit and learn a lot that speed up my building.

Currently it is maiden using a scorpion 2221-10 + kontronik 4:1 gear box...I just weight it with 2200mah lipos it comes up to 1350g ....
I just got my 480 with 5.2:1 from Kontronik which I will fixed it up...it should make it slightly heavier.

Keep us posted on your progress...

Update

Hi Jonathan,

that's great, they should link up rc network and daddyhobby ! Regarding your config, I also contemplate using a smaller battery (1800) to save some weight, but am not yet sure whether I need the larger battery to create some weight in the nose.

Btw, we share another great plane, I also have the Taser in the Carbon version, since then I am hooked on PCM!

good luck, Scooper

.... by the way, always happy to help if you ever get stuck with german translations - I admire you for the pain going through german websites! scooper

Scooper, yup I follow your path...I got the Taser carbon that is when it open me up to PCM. And I got lucky when I asked if there is any Erwin available when I order the Taser spare. Now I am even more convince.

I survive using translation to get on German site...my two helis is actually made in Germany and only available in Europe.

Question : I had a small carbon rod epoxy on the canopy to secure it...It didn;t work very well. Can you show me what you are doing with the canopy ?

New motor in

My motor delivered today....Kontronik Kira 480 wiht 5.2:1 gear box...

Nice motor, heavier probably give me a little more penetration that I think I will like ...





The beauty is the easy wire management and make it looks nice now.
Still got lots of room for telemetry unit if I choose and the lipos still have rooms to move in and out to get the right C.G.

Canopy

Jonathan,

same problem here with the canopy and there is no description in the building instruction

I used a 1.2 mm steel rod to fix the canopy but due to the shape of the canopy there was insufficient tension to hold it tightly. I have now inserted two small carbon plates underneath each side of the opening of the fuselage to increase tension on the rod (approx 2 mm each). This works better but still not perfect. Maybe I just fix the canopy in addition to the rod with some tape, will review this after some flight practice....

Yup...I have to use tape to ensure I don't find the canopy missing....let see what else we can come up with.

Scooper,

I might have found a solution...it seems to fit well ... here is what I did.




I do need to do something to the appearance of the canopy from outside view... should have spray paint on it before I work on it...

Canopy

I see your logic, that is going to look ok when you spray the canopy, worst case you have to order a spare part canopy and try again ;-). Btw, are you flying in Singapore (?), I know it well as I lived there for five years (without planes, though...)! Scooper

Scooper , yes I am and fly in Singapore, limited area but good enough for me.
