The other issue is that for a small EDF, like a 30mm or even 35mm, the KV rating is fairly low. You would need to run it at least 4S and I would say perhaps even higher.

Of course my doing so you could use much smaller batteries and just run them in series. ie 4x 120Mah.

Slaanesh,

As to mounting the outrunner. Not really an issue. I can modify the mount to fit the housing. Or make one. Haven't really looked at it yet. Also, as pertains to the kv rating, you are no doubt more knowledgeable than I. It's just that many if not most of the edf outrunners listed at HK have kv ratings close to this. Those ratings are what I was basing my assumption that this motor would be okay.

Here is an image of how the latest build is progressing, and one of the modifications to the motor and edf unit.

The motor has a threaded pushrod adapter mated to the shaft to allow the rotor to thread onto the shaft. The modified housing showing the intake lip removed. The 6 blade rotor less three blades. The other image shows the fuselage sections.

Some more.

Some of the nacelle sections still need the centers removed. The rear section will have a thrust tube installed. Cone Layout was used to design the thrust tube. A circle cutter is used to remove the material for the fan ducting after the nacelle sections are formed and assembled.

The thrust tube was printed on plain printer paper. After its formed and installed in the nacelle it will receive a coating of WBPU for stiffening and adhesion.

Thanks, NC. I'm trying to document each step. Hope I'm not being too rudimentary.

Thought I'd better post on the progress, although as much as I hate to admit it things aren't going as well as I'd hoped. I'm already @ 45g for the empty airframe w/o the tailplane installed. My objective was 25g to 30g.

I intend to complete this one as I feel I'm on the right track and am gaining some valuable experience.

I'm also toying with the idea of adding a third cell to the battery pack, though I'm not sure how the motor will bear up. It's only meant for a single cell and I'm afraid I was already pushing it running it on 2 cells. http://www.hobbyking.com/hobbyking/s...idProduct=9068

Comments/suggestions are welcome.

If you have the skills to tune a fan up, I would suggest the 6 blade venturi style AEO 30mm unit. That will give you the static thrust to push a heavier model without loading the motor or lipo down too much like the 8 blade version would.

If you don't mind spending a little more money - the KP32 unit is a little screamer and would have the power you are looking for too.
