Several things that I wanted to achieve with this build...a more aerodynamic intake and exhaust. A light but powerful set up, a fantastic scale looking bird with excellent flying qualities...

Bare airframe with CS11B fan and shroud, stock JP motor w/ cooling holes drilled in forward motor housing, 30A HW FF ESC, 2 HS-55 servos, all Du-Bro Connectors and CF rod, Callie Graphics...Foam-Tac hinges and modified ducting...

More details to come......Continue Reading

Again...my apologies on lack of details...they will come shortly, just trying to sort through all of my accumulated photos first.

Main goal with this build is to get her somewhat light...but very fast and powered by Don's Wicked Wemo 4800Kv on 4S 1300mAh 45C.

Build includes "Dryer Sheet" glassing of Leading Edges and Scoop due to my foam eating flying field.

Flight Report: AWESOME!!! Took some serious de-tuning to really make her behave at the high speeds, very little movement needed in AIL/ELE at 100 mph :-) Will slow to a crawl...literally launches itself out of your hand. A joy to fly!...Continue Reading

My goal was light...powerful...and to be able to easily carry a 3S 1300mAh 45C Lipo.
It worked...really well!!

For the 3S 1300 45C to fit (CG ) I moved the battery bay aft. Had to remove a bit of material on the bottom and made grooves for wires to go forward of the battery (Sat and LiPo feed). I did do a quick layer of "dryer sheet and CA to be bottom of the battery bay.

The Rx is mounted in the fuse aft of the battery. I cut a square out of the top of the fuselage to assist in placement and wiring (Silicon fastened). I did take the plastic plugs off of the servo wires and used heat shrink to protect each wire (Had to give the wires a slight bend to fit in the area(didn't have a slim Rx with plugs on the side...).

Intake was sanded smooth and exhaust received a thrust tube (95% FSA for the CS11B fan/shroud, and a J-Power stock motor).

I set up the AIL's to have minimal throw( This thing spins like a drill) and CG is at the stock position.

I used Foam-Tac for ALL joints and did add some short pieces of CF rod to both the wings and tail (not really needed for this light bird).


More details to come...

Fight Report: Next to the Screamer...this is one of my favorites. Fast, slow, well behaved and CRAZY maneuverable. Best 2:30 minutes of flying.

Been a bit slow getting some of the details up as I was doing a lot of experimenting and sourcing of parts...but working towards a 5 blade main and a 4 blade cascading tail (rotating on the left side for more scale appearance), full lighting and the best part...easy instal and removal of the frame from the fuselage for any repairs/adjustments...more to come.

UPDATE: Lovin' this build, but ready for it to be DONE!! Almost there.

UPDATE 4/24/14: AWESOME!!! All systems go! Blades custom painted/balanced/tracked...re-zeroed swash and checked all control systems. Got rid of a small bind in max extent of tail pitch slider...tail is ROCK solid and sounds so good! Was getting frustrated with it, but so glad I kept pushing

I have some video that was shot early in the fine tuning of the frame...need a camera person for final footage in the fuselage w/ lights. The sound and smoothness of flight are fantastic...and handles the wind very well.

Here is the initial test flight footage...
MD500D Test (3 min 31 sec)


Running two 2200 3S 40C's in parallel...solid 4:30 minutes and packs are at 60%. I do notice a slight drop in "umph" at about 4:00 ...but it is a heavy bird.


Comments welcome!...Continue Reading
