 Grin Really missed seeing that. Too bad, my landing gear has to be rebuilt. I think having that horizontal strut is not a good idea. Even short pebbles can damage the gear. Had no option as couldn't get m2 bolts here.

Hmmm, will moving the strut a little up help?, or perhaps having a cross bar design; might add a little to the clearance...just an idea...

The strut serves dual purpose. For the wheels to rest on it and support. So moving up will not help.

Thank you Sameer!

Haven't really thought about next. I'm yet to absorb the fact that I could build a plane that can fly as well as shop RTFs! Just want to enjoy flying this till I get bored  Grin

...a cross member construction might help...

Totally agree on the gravel spoiling the landing gear. I've been toying around with the idea of having a portable runway, something I can roll off like a carpet and take along to the field Cheesy

Thank you VC sir! Yes, the chatter really spices up the video.

Regarding amps draw, for 9x6 prop it was around 22 amps. I checked with 10x7 prop as I didn't have 10x5 and it was still within 28amps. Finally flew with 9x6. Appeared to be very efficient. I think we flew for 10 mins (3/4th throttle. Not very sure but it was not more than 3/4th) and it had drawn about 700 amps.

I'm thrilled at every plane's FFF, which quads don't have... cool videos!!! Smiley

What is FFF?

Hope your wifee havn't read this post  Giggle

-Vinayak

Thank you Vinayak! She definitely wouldn't mind. She is proud to be technically challenged Smiley  And I don't mind either! Like we (most of us) are culinarily challenged. It's good to maintain your individuality, else life would be boring if all were of same IQ/interests Smiley

...a cross member construction might help...

Thank you Girish! I doubt whether it would be easy to achieve. I think the original BEX's idea of landing gear for the Avispad might serve well. The only think I hate is pushing the landing wire inside the fuse sidewalls. I have got an idea now, will see how it works out.

Very very nice build sir and she is flying very well without dihedral what is the auw  Hats Off Hats Off Hats Off

Thank you Kamaraj! Please don't address me as sir Bow The AUW is around 970gms.

FFF = fast forward flight (I know the term is generally used for helis..)

I'd love to build a plane one day, as fine as yours.  Grin

FY 30A. Please check the first post Umesh. Actually I have not used the stabilization for most of the flight in the videos. The plane is very stable without the stabilization system itself.

Hi All,

My previous landing gear was made from GI wires and as forecasted in forum, that was band during landing Bang Head.

 For experiment, I have made landing gear from Iron Rods used to support cycle fenders ( 2.5 mm and 4 mm Rods).Specs are same for both design except thickness of rod.

A Nut / Bolt arrangement is provided on TOP ( Gas welding)  , which will be  fitted on ply and two small nut to hold axle of wheels ( Gas welding) . This arrangement  has very good strength.

I donít know , it will work or not .All of you are requested to review this design and suggest(weight- not measured , may be 30-40 Gms apx).

Pictures were taken from Mobile , so sorry for poor quality of pictures.

Regards
Mohan

Are you sure it's 3mm? Looks like 2mm. 3mm would be too thick I guess. The reason I asked you is because I wanted to implement the same thing! Do you get flat aluminum sheets or rolled ones? If it's rolled, then I think there would be some work straightening it. How did you cut it?

Regarding your setup, I would recommend this motor:
http://www.rcdhamaka.com/index.php?main_page=product_info&cPath=100_93&products_id=517

...with a 10x5 prop, 30A ESC and 3s 2200 mah battery.

Dear Mohan,

Can't make out clearly from the pic about the fixing mechanism in the top.

While browsing today, I just found this web page:
http://www.foamflyer.info/landinggear.pdf

I think it's a very efficient one to try out.

High spirits we have: gravity we flout.



Make sure your throttle stick is all the way down to the "Full off" position when you connect your battery to esc.
