70% Guided Mite

[Ralph B]

Here are a few photos that my brother Paul took this past weekend of my 70 percent Guided Mite. The basic specs are as follows:
Wing span: 14 inches
Weight: 62 grams
Equipment:Alpex receiver,2 HS-50 servos, JMP type 7 ESC.
Battery: 4 cell 50MAH Nicad.
Average flight duration: 5 to 6 min.
Gunther 5 inch prop on homemade geardrive with 5:1 ratio(Gears are from a pocket watch)
Motor: Mabuchi M20 high voltage wind.

Nice job on the covering. Is that Litespan?

Tony:
Thanks, the finish is Tissue and Dope. Thats all I use- Showing my age I guess.

Looking GREAT! I think your guided mites were my inspiration for my electric mite.

Allan:
Thanks, the Electric Mite looks like it has the same great flying qualities as the GM.

yes, the apple doesn't fall far from the tree. I used similar proportions for the Electric mite as the guided mite. I just adjusted the Fuselage to better accomodate a pair of pico servos, ESC, receiver and a decent battery pack. Direct drive IPC GWS motor works great in this setup.

Although someday I'd like to do a 70% or so version for indoor use....

Now that's what I call small and light.

One question: how slow/fast does the thing go?

It does not seem real fast outside. Based on the speed outdoors,I tried it indoors once and it was way too fast. I have built other versions with rudder only, Magnetic actuator, that weighed less but they were still a little hot for indoor. I guess I would rate the speed as mid-range, just a little too hot for indoor. I am going to build one around 38 grams using the light weight Lahti RX and rudder only on 3 cells which should make indoor a possibility. I did this one with basicly off the shelf equipment(except the gear drive) just to demonstrate that a 42 Sq.In. model with R/E/T is a practical venture nowdays. Did I convence anybody?

I'm convinced, the next step is micro EDF. Obviously the fan and all it's components will have to be home made. What motor should it be built around? GWS, N20's Hmmmmmm......

Speaking of micro EDFs, it looks like GWS is coming out with their own micro EDF real soon now!

Jim:
I agree with you about micro EDF. I did a little experimenting with the Firecracker motor in a KP44 fan which looked like it might work if you had a very lightly loaded model(indoors). I have not had time to get back to it, in fact the GWS motor was not available when I did my testing. My feeling is that you want the highest RPM for the lowest cell count possible and hope the rotor diameter does not get so small it can't work. I would like to look at the KP-00 on 3 cells, maybe Lahti or Micro Mag radio, Magnetic actuators, and shoot for a flying weight of under 40 grams. I think it can be done with the hardware we currently have available but it will take some serious development time.
