Title: "2016 Sweepstakes" Griffin, Balsa kit build Post by: sanjayrai55 on November 11, 2016, 10:14:00 AM Bought this from RC Bazaar
It's a powered glider (sailplane type) with a T-tail. Well packed, good laser cutting and a comprehensive hardware kit. And, the icing on the cake: a full size rolled (not folded!) drawing!

However, they didn't include blind nuts for motor mounting to the firewall >:D :rofl: (https://s25.postimg.org/ur3r56ayn/IMG_20161108_164749.jpg) (https://s25.postimg.org/5mcqrrbi7/IMG_20161108_164754.jpg) (https://s25.postimg.org/ndod67qwv/IMG_20161108_164803.jpg) Title: Re: "2016 Sweepstakes" Griffin, Balsa kit build Post by: sanjayrai55 on November 11, 2016, 10:23:43 AM Balsa and ply is of good quality and well selected. Laser cutting is the best I've seen so far from these kits

The Elevator pushrod goes through the vertical stab The fuse boom is a separate part (to be affixed later) with conventional balsa frame plus a carbon fibre tube for strength. The pushrods go through this tube (https://s25.postimg.org/y4zf7z4e7/IMG_20161110_210814.jpg) (https://s25.postimg.org/y69d1e67z/IMG_20161111_090013.jpg) Title: Re: "2016 Sweepstakes" Griffin, Balsa kit build Post by: sanjayrai55 on November 11, 2016, 10:33:23 AM (https://s25.postimg.org/9r150c7b3/IMG_20161111_090112.jpg)

By the way what's your opinion about the T tail... Sir... Is it strong enough...?? Title: Re: "2016 Sweepstakes" Griffin, Balsa kit build Post by: sanjayrai55 on November 22, 2016, 05:42:25 PM Thanks Dev
The T tail seems OK, but I'll know when it crashes ;) ;) Title: Re: "2016 Sweepstakes" Griffin, Balsa kit build Post by: manojswizera on November 22, 2016, 07:03:38 PM Looking stunning sir

Title: Re: "2016 Sweepstakes" Griffin, Balsa kit build Post by: harshit batra on November 22, 2016, 08:26:14 PM 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 Title: Re: "2016 Sweepstakes" Griffin, Balsa kit build Post by: sanjayrai55 on November 23, 2016, 05:40:43 AM Thanks Harshit. Of course you fly it - you anyways do ;)
Title: Re: "2016 Sweepstakes" Griffin, Balsa kit build Post by: sanjayrai55 on December 05, 2016, 05:45:40 PM 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 https://youtu.be/3eZVjULuVO8 https://youtu.be/ywnRen1JVic Title: Re: "2016 Sweepstakes" Griffin, Balsa kit build Post by: rastsaurabh on December 05, 2016, 05:57:32 PM Nice Flying.
I hope this will be a good glider for loooong duration flights. Title: Re: "2016 Sweepstakes" Griffin, Balsa kit build Post by: sanjayrai55 on December 05, 2016, 06:13:35 PM 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! Title: Re: "2016 Sweepstakes" Griffin, Balsa kit build Post by: topalle on December 05, 2016, 06:17:38 PM Awesome!

Title: Re: "2016 Sweepstakes" Griffin, Balsa kit build Post by: omairk1981 on March 24, 2018, 01:42:07 PM 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. Title: Re: "2016 Sweepstakes" Griffin, Balsa kit build Post by: sanjayrai55 on March 24, 2018, 01:45:12 PM The battery compartment is too small. Also, the additional weight will make it uncontrollably nose heavy

Title: Re: "2016 Sweepstakes" Griffin, Balsa kit build Post by: sanjayrai55 on April 22, 2018, 06:47:09 AM 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 ;)

Title: Re: "2016 Sweepstakes" Griffin, Balsa kit build Post by: rcrcnitesh on April 24, 2018, 06:35:37 PM 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. Nitesh |
