I've recently received these motors and the quality is very good. They run very smooth and seem very powerful after initial tests on 2s with a 3020 prop. After hearing about the wires that come on the 1103s I was happily surprised to see regular stranded silicone jacket wires on these motors. Very thin obviously but stranded. These are going on a LKTR120 frame and fit perfect. Glad to see all the new sizes of micro motors available now as the micro quad scene explodes in popularity. Great job Banggood! Another good product at a great price.

Please tell me your mistaken this motor when you say "happily surprised to see regular stranded silicone jacket wires on" cause I'm holding one at this very moment and nothing but a single wire coming out, now my BR1306 on the other hand are with stranded wires.

Might be a nice replacement for the noisy motors on the Tarot 130

Are there any plans to release 1104 motors with different kV ratings like you have done with the 1103 motors?

I am not sure now but I can ask the factory if they release different KV.
Different KV ,you mean lower KV or higher KV?

Higher KV in the 1104, similar to DYS...6500 or 7000 KV

Yes a higher kv, from what I've found so far having these Racerstar 1104 motors a higher kv version would be a sweet spot for these light weight micro builds.

I agree as well. Something in the 6000-7000kV would be popular.

Really like the new options available now. Question for you tho, why do 6500kv and 7000kv? They are so close to each other. I have the 4000kv and they do well although I think one of the new versions might do better on 2s. I'm running 3020 props right now and I'd like to go to 2.5" props so the higher KV would be better I think. Any chance I could get a set to review and compare to the 4000kv version? Thanks
