85mm /90mm micro brushless drone frame

currently at the moment have only built this in 1S but would like to have the option for 2s the 85mm frame is used with the 55mm bi blade props and the beta fpv 40mm 4 blase props and flies great have also included the 91mm frame option to use with king kong 65mm props (same as kebab toothpick uses) this is a 16mm X 16mm mounting hole frame to use a flight tower stack. i built mine from a full speed rc bee bee 66 lite and i find that the nylon frame performs better than the original carbon frame
