Sure. I love to hook you up. $238+ shipping.

Until then, Here's what I'm putting into my Habu2 foamy.
Wemo rotor
Skyworld housing
Velocity-RC 3200kv motor
Caslte ICE 100 ESC
2550+watts.

For 1500 watts or less, the plastic housing is fine. The Alum housing and heat sink is for the motor's sake.

Hmm 2550 watts for 64,600rpm? Thats a fair whack of watts wasted there, Wemo and HET 1W40 runs 64K rpm at 2080 watts with full size intake lip, the 1W40 would appear to be a pretty awesome motor.

Where would i go about fan placement. My manual has a guide for a 4s but not sure its taking into account a 70mm fan. Also my fan with intake ring will not fit. Should i take intake ring off?

You dont need the intake ring, you will likely need to sand out foam to get the fan to settle nicely in the fuse, and depending on the weight the fan will need to go around 10-20mm in front of the LE of the servo case.

With wemo/2W18 I had the fan about 15mm in front of servo, 80A esc in the normal location, and could get it to balance with both 2600 and 3200 4s packs.

Most guys put the fan (any 70mm EDF) about 2" behind the stock postion. (very close to the servos, but not so close as to interfere with the thrust tube)
This will allow you to go with bigger batteries, For the smaller 2650's, you simply move the battery forward a bit. You have more battery options this way without have to redo things later.

All my electronics wont be in till tuesday. Glassed the elevons today as well as started glassing pylons. Canopy and latch are done. Gotta pick up a couple servo extensions. Still gotta decide on paint job and fix my airbrush. Will most likely be glassing the whole plane. At the very least the wings nose and underbelly. May just end up doing whole thing. Gotta finish this build and my f22 i been working on. Aiming to maiden this probably next thur

Looks good!!! However, speaking from experience, I would add some color to it so it doesn't disapear in the sky. My first one I painted in a blue and grey camo scheme, and it worked On my first lap it disapeared against the blue sky and clouds. Fortunatly I was able to salvage all the electrics, but the battery and airframe were toast!

Is this a 4s setup? Or 6s? Just bought 2 EF-16 kits (my current EF-16 is rather beat up) and 2 more Squalls (so much for no more belly landers) so am in the market for hop-ups... that also could transfer and be usable to bigger 70mm jets later

6s setup. (can also be flown on 5s with less power output.)
The bench test was done with 6s, 40c, 4000mAh, since that's what I have.
The Habu2 will fly with 3200's

We also have the HET 1W-40 (3300kv) in stock.
I haven't tested it yet either, but it's gonna pull higher amps. I'd probably run it with a Wemotec minfan Pro EDF, or Wemo rotor in an alloy housing.

It's never a good idea to go with the sky camo paint scheme.
