Hi guys! Im busy building a 16' predator rigger. This is my first rigger and I still know very little about this. I was thinking of using this outrunner motor. Do you guys think it will do? Im a south african scholar and im building this as a expo project so I need it to be fast. I was also wondering what the overall weight in grams (g) should be for a 16' rigger after it is fully completed.. The build is comming along very nicely and I will soon post pics. Thanks very much.<table cellspacing="3" cellpadding="1" bordercolor="#0062c4" border="0" bgcolor="#d5daff" width="800"> <tbody> <tr> <td bgcolor="#ffe1ff" valign="top"> <div align="center">High Quality</div> </td> </tr> <tr> <td bgcolor="#ffe1ff" width="391" valign="top"> <div align="center"></div> </td> <td bgcolor="#ffe1ff" width="610" valign="top"></td> </tr> <tr> <td bgcolor="#239ac7" valign="top"></td> <td bgcolor="#239ac7" valign="top"><span class="Style2"><span class="Style1"> SPECIFICATIONS</span></span></td> </tr> <tr> <td bgcolor="#ffffff" valign="top"></td> <td bgcolor="#ffffff" valign="top"> <p class="Style12">Brushless Motor KDS WS2217 3800kv for 450 size helis</p> <p class="Style12">High Quality product.</p>
