pat7874 Pleasewhen you receive the lens let us know if that optional lens solve the vison problem: I think we are many to have the same issue above 50 years old ! Thank you in advance.

pat7874 DearSir, did you measure the real capacity and the internal resistance ? the reason I'm asking is because 4500mah 3s 75C and ONLY 274g is way better than any lipo on the market ! that battery would be at 182W/Kg when lipo's above 20C are usually between 120 and 160 W/kg .(only the transmitter/receiver 1 or 2C battery can reach 180W/Kg !!?? If the spec are true, then this a real bargain. Thanks to let me know .

pat7874 Do you want it also to make the coffee, for the same price obviously ? :-)
