The Landing Gear is my idea: to save the belly from the rough ground at our field

Thanks Dev

The T tail seems OK, but I'll know when it crashes ;) ;)

It came out great sir ,looking very nice
Eagerly waiting to see it fly ,may be i can also try my hands on it ;D

sanjayrai55

Thanks Harshit. Of course you fly it - you anyways do  ;)

Maidened it yesterday. CG was a little tail heavy at the designed mark, and needed some left trim.

Video only of the maiden; subsequent flights after corrections it flew fine

The wheels were not a good idea on grass, it would flip on landing  ;D But they will be good on hard ground

Nice Flying.

I hope this will be a good glider for loooong duration flights.

sanjayrai55

Thanks Saurabh

Did 2 sorties, total about 4-5 minutes. On the 1300 mAh Lipo had 72% balance

So on normal powered flight it should be able to cross 17-18 minutes

How it behaves if it catches a thermal has yet to be seen though. Unfortunately, that is easier in summer!

Had some queries about the Canopy fixing. The original plan appears to have it with screws, which is not good for LiPo changeovers. So used two thin strips of Velcro

Hi, could we use a 3S 2200 mah instead ? Or is the battery compartment too small for that ? Would it handle the extra weight of a 2200 mah ?

Thanks in advance.

sanjayrai55

The battery compartment is too small. Also, the additional weight​ will make it uncontrollably nose heavy

Awesome build,
Is the gap between the Foremost fuse and Spinner is intentionally kept large?   
For motor cooling i guess?

Actually that's the way it panned out. The firewall location and the fuse front end are in the laser cut design. No complaints though; as you said, it does contribute to cooling the motor  ;)

Awesome build  :hatsoff: Sanjay sir,
i had also built the same glider with solar panels.

A beautiful build sir. Could I ask a few questions?
What panels are those sir? What was your goal? 24h flight or 12h flight? What batteries did you use? Could you start a new thread or should I PM you?
Sorry for so many questions.
