Hi Rajesh!  Sounds like you're ready to do some reading on the wonderful world of SPADs!  A good resource is www.spadworld.net.  Then RCU has a SPAD section with a lot of info:  http://www.rcuniverse.com/forum/forumid_178/tt.htm  RCGroups also has a good SPAD section:  http://www.rcgroups.com/spad-simple-...e-designs-176/<div>
</div><div>Looking at your specs, I doubt seriously you're going to be able to get a plane of that size off the ground with a .45 engine.  You're closer to the size of the Ultra Spadstick which most guys fly with a 45cc gas engine.  Check out the Debonair:  http://www.spadtothebone.org/PDF/Debonair.pdf  It is an easy to build .40 size trainer and the instructions on the web site are great.  Hope this info is some help.  Welcome to the addiction! </div>
