Some of the responses, are biased. Not obvious. rfodor...the CS 10 blade runs well on the 42 with 4 cell. A wemotec mini uses 1200 watts from this combo, the CS 1800. Thrust from the wemo is 3.8 pounds. Thrust from the CS is 5.1 pounds.
The CS multiblade fans are designed for more power. Need more. Get more. Hard to balance.
Extreme...Alot of the response is due to the way you want to sell what you stock, and since you don't stock Velocity inrunners, you bad-mouth them, in fact anything outside of your sales envelope gets a biased review. I'd check that. Check yourself, because a forum is an exchange of ideas and information. Not a sales pitch
Will answer your post from bottom up...
Sorry? Where did I bad mouth velocity? If I thought they were worth selling I would sell them. I used to stock ARC but had too many issues with them and returns cost me a fortune in shipping, so I asked HET to make motors that fitted the categories we all needed at the time, the 1W30 was revised and the 1W40 was born and its about the best of the long can motors in the 3200-3300Kv range.
I have seen velocity results and compared them directly to ARC results, gotta be 2+ years ago now, velocity 3200 pulled 108 amps in the Minifan to produce 2.5kg thrust, the ARC 2858-1 pulled87 amps to produce the same thrust. You work out the maths on that and tell me which motor you would run, nothing to do with bias, simply best performance for the watts.
Now the 1W40 has surpassed the ARC, 93.6 amps for 2.7kg sustained thrust, data that has been emulated by many others around the world, its simply known facts, nothing to do with bad mouthing anything, if you think I am bad mouthing a product then you are not reading the posts very carefully, I am and have always been impartial, I dont make the stuff sohow canI havebias towards one product?? I have been offered supply of 99% of the edf products on the market if I wanted them,
I take on what I believe to offer the best value in $$$ and watts/thrust and if there are big discrepancies in the perfomance of 2 products I will list them, tell me how that is not helping the readers? Of course if you are a fanboy of a particular seller (not saying you are), then you have more of an agenda in accusing me of bias.
Ok CS10, you are using 1800w to get 2.3kg thrust on 4s, the HET 2W30 uses 1600w to produce the same thrust on 6s, and I think the Eflite is close to this too.
How many amps are you pulling on 4s?? 1800w/14.5v for example is 124A! So you need a big ESC, and lots of battery to get any sort of run time. The 2W30 is pulling 75A, runs on a regular HW80A esc, and can run comfortably with 3200mah packs.
The Wemotec fan cannot be compared to the CS10, the load is different. You would not run the cool 4200 on4s with the wemo if you wanted a comparable setup, you would have to run it on 5s at least, and to get higher thrust you would run the 3200Kvon 6s, forthisthe figures are as I stated above, 108 odd amps for 2.5kg thrust.
The CS10 are not designed for more power, its simply a chinese fan that sounds good and thats why everyone is jumping on it. I use it in 2 models, both set up around 800-900 watts on 4 cells, when set up with a properly matched motor the CS10 will match the wemo fairly closely, my F16 is flying just as well with the 880W CS10 as it was with the 800W Wemo setup.
Oh and I dont sell Eflite anything, but I still recommend the BL32 motor when someone outside OZ asks me is it any good in the CS10 fan, you know why??? Because it IS a good motor in the fan....
