Aside from no listed price, there are no thrust numbers, or motors they test them with. Sounds like a lot of computer generated results. But here's the real question, What motor out there turns 100,00 rpm?---
" 7：The speed measuring range: 60 ~ 100000r/min "


I'll stick with my original choice, the FANJET 90. At least Rainer put out some numbers, and motors that can be used and what what you can expect!

Price of waiting for the HET Notice

yusenwang,

Do you have straight lip inlet for your fans that need installed into a fiberglass duct?

Also, I gather from your information you have partnered with HET to distribute your fans and parts?

to the crowd, I thought the AMA has already approved alloy/aluminum fan blades as long as their enclosed in an aluminum shroud across the board. There wasn't any money for an accreditations committee

Kick off first selling action in europe by amaxrc.com!

With high demand in the european market and tight coorperation with amaxrc,

, we decide to kick off the selling action of our highest quality full aluminum ducted fan set in germany.

Amaxrc is a well known jet dealer in europe, it has lots of experiences in the turbine jet area.
After verifications, amaxrc decided to go into the EDF jet market with our high qualified EDF parts,

, to fullfill the highest requirements on the turbine jet conversion and EDF Jets.
For information and support pls contact info@amaxrc.com

how have you made "high Qualifed parts " ?? have you flight tested ...or just held it in your hand . you need to get some time on these before you can say high qualified parts.the alum material used needs to be very high Quality.

maybe you should read the posts. he listed the aluminum grade being used on these.

The alloy used is not the same as quality.

Interesting fans! Likely too pricey for my models but once performance is proven, they will sell to a certain group.
I don't understand why some posts slam new products. I have always though it better to say nothing if you have nothing good to say.
Cheers

New?............ in fact they bear an uncanny resemblance to the Mach, ALL ALLOY EDF.

Mach EDFs are all original designs by Mach Chuang



The shaft collets for the tornados are different and appear to be "off the shelf" from another source.
From what I know, these fans are from China, and the "Taiwan Tornado" is a trade name given to the product by a USA retailer.

A few folks PM'd, asking if these were made by Mach.
No, the tornado is not a Mach EDF product.

TAIWAN TORNADO,This guy copy my fan and ideal,.the fan's factory in china not in Taiwan.

........

there you have it ..thats what i was getting at .

I bought a Efflux EDF last year. It was All metal material.Dynamic balancing was done. And it was good. Last month I bought a new TAIWAN tornado EDF for comparison. Surprisingly, the TAIWAN tornado EDF was even better in terms of dynamic balance and power. The sound was amazing and the blades were precisely assenmbled. By the way, the dynamic balance will remain even if the blades were reassembled,coz i tried it out.
