Hi, I just received thoses Gemfab 3025BN for my tarot 130 fpv with Tarot MT1104-4000KV motors and at first, I must admitt I was really unhappy with them. The weight is 0.98 grams for one (versus 0.62 gramms for stock). Thoses propellers are also more wide : 5.24 mm instead of 4.13 mm for regular (3025 versus 3020 of course) Due to this extra wide, the 6 mm screws coming with the motos don't fit because they can not reach anymore the motor thread. M2 x 7mm screw are required for this setup ! As M2 x 7mm are not really common, I used M2 x 8mm with 1 mm spacers, ( 8mmm screw will touch and damage the copper of the motor). Then the total of each screw is now 0.34 grams instead of 0.20. As we need 4 propellers and 8 screws sets, the total additional weight for this propellers are (for the moment mm with 8mm screw - I already ordered M2 x 7mm h3ex screw on e b a y as do not find out here) is : 0.98 x 4 + 0.34 x 8 = 6.64 grs vs 0.62 x 4 + 0.20 x 8 = 4.08 grs 2.56 grams more ! Should be only with 1.6 grams more with M2 x 7mm (22 grams each) I also tested them in flight and I must admit now that except the screw issue, I pretty have more torque with those propellers... then more speed and sensitivity... Maybe mean more crashes :) These are 3025 (versus 3020 for stock tarot props). I recommend !

These are well-made propellers. They are balanced and stiff. Perhaps they are designed for multirotors other than my Tarot TL130H1, which has a set of 1104 4000KV motors. The holes for the motor shaft and the screws are too small, and a lot of effort is required to fit onto the 1104 4000KV motors. As the propeller is thicker, the stock screws barely screw into the motor. These 3025 propellers did not improve the throttle response of my TL130H1, but I suppose they will work better on other setups.
