This post is a "work in progress", for now i'd just like to collect a list of prop brands. Trying to think of some sort of rating (10/10 to 0/10? Good/bad?), and a proper format for the list. Suggestions welcome. Please post brands i forgot and what experience you had with them, if possible including a link. Best would be a link to the brand's homepage, but any link will do for now. Also, there might be good props amongst mediocre brands which deserve special mentioning and a better rating, and vice versa, like the gemfan 5045HBN for example... ALSO i'm not interested in 3s experience. They NEED to hold up on 4s at least.

Would it make sense to have 2 lists? One for a general brand rating, one for the exceptions? • Posts: 203 Threads: 39 Likes Received: 42 in 32 posts Likes Given: 1 Joined: Jul 2016 Reputation: 2 I would have to give a 10/10 to HQProp 5040 (both tri and dual blade). Nothing I've found flies as well as them. If they didn't break so easily I don't think I'd ever fly anything else.

Dal Cyclone 5045 is my favourite prop right now. Cant say much about HQ 5040T because I only have one set and I'm too afraid of breaking them Kingkong T5040 is nice on high KV motors, but feels a bit slow on 2300kv Posts: 2,410 Threads: 136 Likes Received: 1,790 in 1,052 posts Likes Given: 3,302 Joined: Jan 2017 Reputation: 50 03-Feb-2017, 10:57 PM (This post was last modified: 03-Feb-2017, 10:57 PM by Drone0fPrey.)

Before you read, I love lighter props and mostly fly freestyle. KK 5040 are always in a mid-range of all my tests thrust-wise, better than triblade DAL 5040 for example. I agree - great on high kv. Would be a perfect light prop if they were a bit more efficient. Work GREAT on DYS1806 2300kv / 4s. So far I have flown Racerstar 5042 mostly on 1806 on 4s and they felt great. But that fact that those motors were able to spin them makes me think it's not a powerhouse I have yet to test them on my stand. Felt smooth (I wasn't punching at all) on high kv though - tornado T2 2600kv. Seem to be VERY durable - haven't changed even one until now, but that is only 7 packs with a few crashes on trees/frozen snow ;p (BTW, are those OEMs of Shubkraft Wings? I've also seen some other brand selling those) Gemfan 5040x3 - lightweight prop, powerful for its pitch, great, smooth flying, pretty efficient (esp. on high kv), worked great on every motor I've tested. Would be perfect, but... they explode on lightest impact. Use when you do not intend to crash ( ) I think it would be great to summarize this kind of descriptions in a separate thread - this is telling more than a single number, some props are better in racing, where pure power and durability are most important, some are better for freestyle (that butter smooth feeling).

I won't judge on durability here as long as they hold up in flight... Personally i prefer breaking props to breaking motors, but you're right of course, a racer guy might have a completely different view on that. • Posts: 1,070 Threads: 70 Likes Received: 742 in 378 posts Likes Given: 577 Joined: Jan 2016 Reputation: 44 (03-Feb-2017, 11:56 PM)fftunes Wrote: I won't judge on durability here as long as they hold up in flight... Personally i prefer breaking props to breaking motors, but you're right of course, a racer guy might have a completely different view on that. That's one of the reasons why I prefer lighter props, they mostly bend or break In most cases, serious racers make 2-4 axactly the same machines for championship. They don't care during the race • Posts: 2,410 Threads: 136 Likes Received: 1,790 in 1,052 posts Likes Given: 3,302 Joined: Jan 2017 Reputation: 50 Yeah maybe eventually we make a chart which contains columns and check marks for racing/acro/both. Durabilty scale 1-10. Thrust scale 1-10(for quick comparisons) along w/ actual #s when available. Weight scale 1-10 (for easy quick comparisons) along w/ actual grams. Just some thoughts for future developments (only my opinions) • Posts: 41 Threads: 7 Likes Received: 17 in 7 posts Likes Given: 13 Joined: Feb 2017 Reputation: 1 So I'm really interested in trying to make a little web app for this to gather the data in one place and provide rating and search. It'd be a good exercise for me. I'm going to circle back with some listings of what I think you all are suggesting be added as data on each prop. • Posts: 41 Threads: 7 Likes Received: 17 in 7 posts Likes Given: 13 Joined: Feb 2017 Reputation: 1 How's this look for a draft Prop Data group?

Not sure wether we should define what they could be used for (race or not). If user can sort by thrust, weight, durability etc it will be their decision what they use it for... just a thought. Appreciate your work. Would be nice to have a proper table, sorry i can't get myself together to work on this right now. Will add some pics later though of all the props i had on the scale so far. • Posts: 41 Threads: 7 Likes Received: 17 in 7 posts Likes Given: 13 Joined: Feb 2017 Reputation: 1 (23-Feb-2017, 08:38 AM)fftunes Wrote: Nice idea.

That's a good point. May move 'use' to 'recommendedUse' under the review section. Also going to add 'bladeStyle' to the properties. • Posts: 1,149 Threads: 50 Likes Received: 704 in 450 posts Likes Given: 1,189 Joined: Sep 2016 Reputation: 30 23-Feb-2017, 07:08 PM (This post was last modified: 23-Feb-2017, 07:11 PM by fftunes.) That's the props i put on the scale so far, have some more to measure but no pics yet. Some are attachments from another forum, hope they work for this here. HQ5045 & HQ5045BN Ignore the Tarot, they break on 4s. |
