Post by: Harsh17 on December 03, 2013, 10:50:01 PM Well rcnitesh i was also thinking about same
Thanks for your reply buddy :) Title: Re: Help me to choose a battery !!! Post by: yashodhanp on December 04, 2013, 12:12:07 PM It seems your model is way too overpowered for its small size. Try going for a lighter motor with a lower thrust. Your model is as it is much smaller than the actual plans. And also try using a 2S setup for the same.

All these days i was thinking that it is underpowered :( :( Are you sure ??? My plane's lenght is 30 cms. While its wingspan is 48 cms. Title: Re: Help me to choose a battery !!! Post by: yashodhanp on December 04, 2013, 04:49:20 PM The full scale one was designed to be used with a CD-Rom Motor. So you should scale down accordingly.
Title: Re: Help me to choose a battery !!! Post by: Harsh17 on December 04, 2013, 08:09:40 PM Yeh i saw that but it was rewound accordingly
I myself made one. It was quiet powerful though Can you tell me what will happen with overpowered setup ?? Title: Re: Help me to choose a battery !!! Post by: yashodhanp on December 04, 2013, 08:24:42 PM Low flight times. I don't think the structure is designed for such loads etc.
