<p>work in progress.</p><p>Modification to the Roma F4 LR frame to secure a Li-Ion battery tray. &nbsp;</p><p>Battery spacer is to allow two 2cell trays to create a 4s battery pack with replaceable cells. &nbsp;</p><p>the plate allows for a battery strap to be mounted without potential damage to or interference with your flight controller. &nbsp;Even if you dont use the Li-Ion trays, the battery strap cutout can be useful. &nbsp;</p><p>The quad shown is still in POC state. &nbsp;I transferred a badly flying quad to a new frame, only replacing the VTX with a speedy bee TX800. &nbsp;The mamba 411 board has no BEC, so the 5V input was better than taking VBAT from the battery pack directly. &nbsp;There will be updates to better secure a more appropriate antenna&nbsp;</p><p>&nbsp;</p><p>History. &nbsp;This project started as a 2s liIon 3dprinted 4 inch frame. &nbsp;after exceeding the 250g boundry, I gave up on 2s in favor of 4s and the difference is worth the extra weight. &nbsp;This is not a freestyle ripper, but a long range recon. &nbsp;</p>
