Waiting for the electric retracts and stronger struts. Nevertheless I used some JB weld to strengthen some of the joints.

I added a rudder ...

The full flying stab is cute, but won't last long (how do I know ) in a foamie.

I use instead the much more robust (for a foamie) traditional KISS setup.

The new HET 650 motor offers the possibility of using both 36mm (WeMoTec) and 40mm diam (HET 700) EDF fans. So I went that route.

This will be a nice testbed to finally test the (hysoled and balanced) CS 12-bl fan and see if it's any good

https://www.rcgroups.com/forums/show....php?t=1521751

The fan will be mounted so that it can easily be swapped.

The Hawk will also give me a chance to test this new HeliDrive controller (YGE clone) to see if it's any good. What a brick

120A HV esc opened at both ends to allow better air cooling

Canopy glued on frame with JB weld (gives good rigidity).

Tamiya Red and Testors Acryl Cobalt Blue are a very good (almost perfect) match for the original colors

What I like about the Hawk is that there's a ton of place for batteries up front

The speed controller (120A HV) is installed above the duct so that it gets plenty of air ... also the battery cables are kept short this way.

And finally, it does not throw the CG off by much as does sit right over it.

I have also made some improvements on the ducting by shaping some styrofoam blocks.

Some finishing and spackling is still left to do, then I will glue the shaped blocks securely in place.

The motor wires will eventually get wrapped up completely in aluminum foil.

Landing gear and struts arrived (from www.hobbywhere.com) ... the new mechanisms are 4mm diam, the new struts are solid but a bit heavy.

Everything works fine, but the extension cords had the wrong polarity plugs crimped on

The new wheels are really heavy, the new struts are quite a bit longer which causes some issues.

I dremeled out part of the wing to get the new struts to fit, but I think I will go bakc to shorter struts due to the nosgear probloem (see below).
