These are mounted on my Tarot 680 Pro Hex with T-Motor MN3110-26 KV:470. After slight balancing flies smooth.These props work well enough. The hub balance is way out on them, but the blade balance was pretty close. The price seems fine for what you get. Not much in choices in T stile 13" prop out there.I use this propellers on a quanum spider frame with 4 x multistar elite HV 268 Kv endurance motor and afro ESC 20A HV Quad weight 3400 grams
Lipo pack 8S 6600 - Hovering drain 11.5 Amps
Total flight time 35 min
Noisy but very good and responsivevery niceeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeThese Carbon Fiber props are very well made and pretty close to balanced right out of the package. I'm running them on my Spedix 650 Quad and they work great. Actually this is my second set, after a spectacular crash where I tried, and quite sucessfully briefly turned my quad and these props into a flying chainsaw, taking out several tall tree tops. The blades held up quite well. The tree's did not. It was the fall from 65 feet to the ground that did it in. Actually the props survived. I'm only replacing a set out of paranoia. Great buy well worth it good quality.Good propeller but not so efficient as the top-branded ones. Has around 30pcnt less efficiency than Turnigy slowfly 1347 propellerLight weight and great performance, i set one these into a 580kv quanum motor running 4s and get 14 amp at full throttleThese are the best props I have used on my quad yet. Increased my flight time by 4 minutes! I was amazed at the performance. I am ordering a set for my hex copter. I did have to tweak them to get perfect balance, but that's usually the case anyway. These are GREAT props!De bonnes hlices pour multicoptre me semble-t-il, mais mfiez-vous de leur quilibrage qui n'est pas rgulier.3 out of 4 props were spot on with minimal balancing on the 4th. Horizontal & vertical balance, runout, weight and size is consistent/excellent and not just this order....all of my orders. I had them in my hand in three days. Got a problem, contact support and get a response and solution in a timely manner. Try this w bang good.
