This time various 8-inch propellers are tested with a 2507 motor. Thanks to Brainstorm from RC Groups for donating the props.

      Are those 1500kv any good for 7″

      Thank you for doing this test! I have flown some of the props in this video with a similar 2508 motor and these are my thoughts on them:
      HQ8045- Not very efficient(like the test shows), but it’s actually really fast in the air and has grippy, “locked in” feeling with a light AUW.
      HQ8050E- This prop and the graupner version it was cloned from is the best all rounder for 2507 and 2508 motors. It’s fast(90-100mph on 5s with a 1500kv motor), efficient, and has the BEST response times with smaller motors.
      HQ8050BN- Great cruising efficiency and has good acceleration, but it feels very sluggish and the top speed isn’t any higher than the regular 8×5. I think it needs a much larger motor
      MA8045(smaller version of MA9045)- This one will give you the best flight time hovering or going reeaallly slow. Unfortunately, the blades flatten out under high throttle and the top speed suffers. It’s also nearly impossible to get rid of jello with these props.
      APCMR8045- Similar to HQ8050E
      Graupner3D 8045- Haven’t flown this.
      Not in video:
      APC8060- This one is FAST… It’s way to much prop for a 2507 or 2508 motor, yet it still somehow feels good in the air. It’s about 5-10 mph faster than the others and has the most brutal acceleration. I think this is the best 8″ prop, but It matches best with a bigger motor like the brotherhobby 2812.
      MA8X6X3 tri-blade- I haven’t used this one, but I heard it is the best one for making smooth, jello free videos.

      This hobby is really special, i was hoping for 2305 around 1200~1500KV for a while, it just never happened and now i keep seeing some beefy motors with low KVs being released…
      I might fire up the credit card on this one though lol
      Hope you are doing well my friend 🙂
      Have a great weekend and keep on flying!

      Hey dude, I’m just starting to watch the video, but one useful info: Pawel Spychalski (if I didn’t write it wrong) has a 7″ quad with those motors. He uses the 1750kv on 4s with the Dal Cyclone T7056C (or something like that).
      So, anyway… If you can try them, test with that prop. ?

    5. MC's Creations

      Great testing and comparison, man. ?
      Those motors are really great! ?

      I have a question, To avoid a Lipo house fire. What would be a good rule of thumb for Lipo battery internal resistance level. I know enough to check them for internal resistance only when they are fully charged. But how much IR is too much? When they were new, the IR for each cell was around 7 to 8 ohm. I write the IR numbers on the battery when I buy them. Right now I have 8 Tattu 850mAh 4s batteries that are 1 year old and show an IR of 14, 13, 14, 13. None of them are perfectly flat anymore. They all look a little puffy.

      6s??

      Was kinda hoping to see 1200kv, 6s, 7 inch prop test.

      1500KV 2507 on 7″ really isn’t that bad for 6S, even trying to race tight tracks. I still get better flight times than even my efficient 5″ and 6″ racing setups, although part of that is the 7042 Biblades being biblades. The 1200KV are really for efficiency, and they’ll be absolutely amazing for that – I’ve actually found that for my flying style, the extra weight of 2507/2508/2408.5 size motors actually results in better overall flight times because they’re not stressing themselves and the batteries in turns trying to keep up.

    10. Justyn Markland

      Great test as normal. Keep it up. And please get to that big BH motor.

    11. DirkaDirka07

      Amy chance you can test the HM EX1102 8500/9000kV and maybe the Hyperlite 1103 8000kV motors?

      2806 avengers are comming soon 1700 and 1200
