This is another glow to electric conversion.  I had seen this exact kit converted before and just copied what he had done exactly.  This is the World Models P-51 kit.  The specifics on the model are as follows:

	World Models P-51 Kit
	Maxim N32-13Y brushless motor and controller
	MEC 4:1 Superbox gearbox
	15×8 wood zinger prop (not pictured, but works better than the MAS)
	22 x RC-2400 cells
	Flying weight is 8 pounds

The conversion to e-flight was fairly simple.  All that was required was to cut a hole in the top of the fuselage, construct a battery box, and build a motor mount suitable for an electric motor.

 

	The battery box is a simple piece of 3/32 birch ply with some velcro straps to hold down the battery pack.
	The motor mount was a bit more tricky.  It is laminated pieces of spruce, built up from the firewall of the plane to hold an Maxim motor mount.  Notice there is a place on top of the mount to hold the speed controller.
	The radio gear is mounted per-instructions, however, notice I am using a separate flight pack instead of using a BEC for the radio.

 

 

Total Construction Time = It took me about a month to get this one together, and get all my modifications right.  So, approx, 2 weekends, and a bunch of weeknites fiddling with it.  The kit comes as an ARF for .40 gas, and I really wanted the conversion to be nice.

Here is my first Twinjet.  I painted it up to look like the Blue Angels.

I got tired of hand launching it, so I thought I would add retracts to it so I could ROG takeoff.

The additional weight of the retracts made the plane underpowered, so I added cobalt motors.

Here are the vitals on my first Twinjet:

	Multiplex Twinjet kit
	Twin Maxx Products 4014 cobalt motors
	Twin APC 6×3 pylon props
	Robart 1/2a mechanical retracts
	10 x Sanyo CP-1700 cells.

The retract conversions were fun…but, they totally changed the flight dynamics of the plane.  After many flights,  I eventually had an accident where I ground-looped the plane, and totally screwed up the airframe.  Several months later I yearned for the stock Twinjet, so I built a 2nd one.

Vitals on this Twinjet:

	Multiplex Twinjet kit
	Twin speed 400 motors
	Twin gunther props
	8 x RC-2400 batteries
	Home made decals using Photoshop and my inkjet printer.

Total Construction Time = A couple of evenings during the week.  Took me just as long to make the decals as it did to build the plane.

Here is my first DAW Extra.  I had a few problems getting it to fly right, mostly due to sloppy construction techniques.  I started out with the speed 400 motor, and eventually went to a 480 because it was gutless.

Here are the vitals on the blue extra:

	DAW Extra kit
	Graupner speed 480 BB Race
	8 x Sayno 600AE batteries
	Castle creations 40 amp speed controller
	APC 5×5 prop

The blue extra had lots of flights before eventually meeting the ground at a steep angle too many times.  My primary problem was I would only get about a 2 minute flight with that hot 480 motor.  So, I built a brand-new one using the lessons learned from the first.

Here are the vitals on the yellow extra:

	DAW Extra kit
	Hacker B20-15L motor with 4.4:1 gearbox
	Jeti 40 opto brushless speed controller
	APC 9×6 slow-fly prop
	8 x Sanyo 1050 NiMh cells

With this brushless setup, I now get 5+ min flights depending upon how much throttle control I execute, and the plane can do just about any aerobatic move in the book…except hover.  Does excellent knife edges, and spins.  Only major accident I had with it was I did an inverted flat spin, and could not recover.  Luckily it landed in high-grass and was not too damaged.

Total Construction Time = 2 full weekends plus a few hours during the week.  The kit comes as a box of wood and foam.  Lots of shaping, carving and gluing to put it together.
