nick789 if you beef the wing up with a decent spar and carbon strips to the ends its ok ,i have one with 2 x 2208 2200kv for scale flying , and another one with 4 x brother hobby 2206 2600kv on 4s , 6inch hq tri blade props and differential thrust for crazy 3d flying . its about a 5-1 power ratio so careful throttle management is a must lol

nick789 rubbish a 3s 2200 is a perfect fit underneath crossways butted up behind the front bulkhead above the front pair of wheels , you will just have to remove about a 5mm layer of foam from the fuz to make room for height of battery , done like this it wont need straps,velcro or hatches cut and the cg is spot on with the standard setup

nick789 search for hobbysky extra 300 and you will find some vids , its been around a while some are from 2013

nick789 frame = 11g , pod =4g , hardware , straps , batt pad ect = 10 g

nick789 20x20

nick789 looks like a speedix gs35 , another well known noisy esc

nick789 yes i wud avoid too ,its a tarted up pg 50 ,i bought one a couple of weeks ago and it never made it past the test hover on 4s , went straight in the trash along with a hglrc titan , so i have learned the hard way lol , now running the hobbywing and a speedix on 6s both have been flawless

nick789 i wud just drill new holes ,i do it all the time ,its a very easy job to do if you use a 20x20 adapter plate as a jig / template {availble on here} use a quality drill bit and a scrap piece of carbon or wood underneath it to stop the bit from ripping through the last layer. hope that helps
