Status: offline 		My next project is to review the Lanier Razor 3D and convert it to electric power. This .30-size plane normally uses a .40 to .50 size glow engine.

My plane is the beautiful (and patriotic) Stars-n-Stripes model.

Here are some specs on the Razor 3D:

Wingspan: 52" (1321mm)
Wing Area: 560 sq in (36.18 sq dm)
Weight: 4.5 - 5 lb (2041-2268 g)
Length: 54" (1372mm)
Fuselage Length: 42" (1067mm)

Regards.

Status: offline 		Thanks, Mike.

This would be your model below. Let me know what you find when you build your Razor 3D. These threads are for sharing information.

I would also like to hear your thoughts on the bellcrank system for split elevator control. Mine works great but I thought it was an overly complex design. I'll post some pictures soon.

Regards.

Status: offline 		To keep my Razor 3D light, I used some Hitec components that I bought from Hobby Lobby. My 4 HS-85 "Mighty Micro" metal gear, ball-bearing servos provide 49oz/in torque and weigh only .77oz or 1/2 the weight of a standard size servo.

My Hitec "Electron" 6 channel receiver is a full strength dual conversion design that weighs only .66oz compared to my Futaba R127DF that weighs 1.5oz.

That's a 4oz or 1/4 pound drop in weight! Not a bad start.

Status: offline 		There were, however, some errors in part lengths and measurements that i'll document along the way.

The 2mm by 20mm screws were too short for the elevator halves so I simply glued them in place. A 24mm length would work fine.

Status: offline 		It looks like i'll use a geared Aveox 27/39/1.5 motor. Depending upon my prop clearance, I can vary the setup.

My initial starting point will be as follows:

  • Aveox 27/39/1.5 motor
  • Planatary gearbox 4.4:1
  • APC 13x8 prop
  • 16 cells of 1950FAUP NiMH
  • 10,000 RPMs at 42amps
  • 80oz thrust, 57mph pitch speed, 600 watts


It may not be a real hover machine but it will at least be a light and strong pattern flyer.

Here I am finishing up the wheel pants and canopy while I wait for my motor mount to arrive.
