WEMOTEC Midifan & Minifan EVO finally here!

Well its been a year + since I first knew about the new Wemotec rotor plans, and finally its here! the new Midifan EVO 11 blade rotor is finished and coming into stock very soon! The Minifan EVO is also on the way and due late 2013.

Oliver has sent me samples, I have an 80mm and a 90mm in hand right now for testing, very interesting design, sorta like a minimidi
Lightweight, blades are very light compared to the old Midi, spoke to Oliver about the changes he says testing has shown no issue with the flex and no stretch even at high Kw.

Anyway I had a 90mm test housing sitting with an HET 700-68-1400 in it so figured why not start with that! 8s and 10s testing.

8s Results:
28.26v /62.5A / 1767W / 34,500rpm / 3.18kg.
10s Results:
36.67v / 95.8A / 3487W / 42,540rpm / 4.8kg.

Looking at the Jetfan table with the same motor, 8s is 2110w for 3.2kg thrust and 10s is 3610w for 4.7kg thrust.

These are only initial tests of course, wemotec inlet lip on the housing, no exhaust, 5000mah 35c packs used for both tests. The 8s is very nice, low amp draw, could use a pair of 3200 4s packs.

I think for optimising the 8s performance the 700-68-1500Kv and 1680Kv are going to be the choices, as Wemotec have said the load is very similar to the Jetfan, from what I have seen so far its going to be fun testing this new rotor!

PRICING:
Midifan 90mm EVO standard fan unit AUD$85.00 (takes 36mm motors only)
Extreme 90mm Alloy Midifan EVO fan unit AUD$139.00 (takes all 39mm motors, HET 700 series etc)
Midifan EVO rotor AUD$39.00
Midifan EVO Rotor & spinner AUD$50.00
