New Front Yard Flyer - FYF


Here is a picture of my Front Yard Flyer (FYF). I built this last spring with the design objectives of:

- use standard low cost components
- simple construction
- build up balsa wing - flat bottom
- Able to fly inside and outside
- Robust - not too sensitive to wind


-I used a beat up wing from a SIG Cub freeflight plane. It's 23.5" and covered with Litespan.
-GWS receiver and servos (pull-pull control)
- pixie 7p esc
-n-20 motor with 4:1 gearing, homemade gearbox, and 4.75" blue freeflight prop
- foam tail
- 2 145 li-poly's in series
- AUW with batts is 2.6oz

8 minute flight duration

Flys nicely and handles wind suprisingly well.
Responsive enough to fly in front of the house.

Impressive


Looking good.

That is an impressive wieght using GWS pico gear. At some weight the risks from having the prop up front drop off. Have you had any experience with frontal assaults yet?

Is the white riser foam? Hollow?

John,

I haven't crashed it hard yet. It will nose over when "landing" on grass but no damage yet. Given the weight it tends to bounce rather than break.

The foam riser is solid meat tray foam (about 1/4" thick).

I may try to different wings next - for kicks.

Quick question


Hi Larry,
Can you please tell me where to buy the N-20 with the gear system ? Bob Selman's site seems to have only the low voltage version. Are you using the high voltage version ? I see you are using 2 Li-Poly in series so i guess you have the high voltage version.
I am new here.
Thanks.

John,

I got the motor at http://www.allelectronics.com/
SMALL DC MOTOR CAT# DCM-166.

2 motors for $1.50.

The gears are Kenway available from homefly.com for $1.00 each.

If you prefer one premade you can get them from GWS or http://www.djaerotech.com/dj_product...ies.html#mps-1


I made up my own gearbox with some piano wire and brass tubing from the LHS.

Good luck

Larry

Connectors


Hello,
What did you use for connectors off the N-20 motor? -Patrick

PS- A close up of the motor with the connector in the picture would help me out a lot in my struggle to see what kinda connectors everyone uses.

I didn't use a connector to the motor on this model. I soldered the esc leads directly to the motor.

On some other models I have used small two pin connectors like this one. They work as male or female connectors. I use them for batteries, motors etc.
