Thank you for the contact information. Is the stab and canopy attachment method the same as CARF Integral? Everything else looks to be straight forward.

Looking forward to your flight report.

Thannk you,
Kevin

Status: offline 		Here is some information my Krill Model Spark:

The as-received weights were:

Fuse+canopy=918 gr.
L. Wing=393 gr.
R. Wing=382 gr.
L. Stab=109 gr.
R. Stab=111 gr.
Rudder=86 gr.
Wing Tube=62 gr.
Stab Tube=14 gr.
LG=125 gr.
Wheel Pants=40 gr.

The finished weight is 4767 gr. with the following equipment:

Hacker C-50 13XL Comp+Comp 90 ESC
FlightPower 5350 F3A 10S
APC 20.5x14
Futaba 3xBLS451 (Ailerons and Rudder)
Futaba 2x9650 (Elevators)
Futaba 5014Rx
Futaba choke on ESC
Jaccio Voltage Regulator

Some notes: ESC was mounted where it is and an air scoop was added to increase cooling—we fly in 90+F most of the summer in south Texas. The batteries need to be well forward if the servos are mounted in the stab due to the long tail moment/short nose moment (see pictures).

Set-up is per plans (all incidences at zero and CG at 30mm from center of wing tube).

Flights to date indicate the following:

Despite the counter-intuitive (to me) all zero set-up, the vertical lines and knife-edge trim are very good.
There is no pitch or roll couple with rudder on knife-edge or flat and level with this set-up. You can make perfectly flat rudder turns with no inputs.
Given the fuselage side-area, the side force/fuse lift is very powerful. However, yaw control is not overly sensitive.
The snaps are effortless thanks to the saw-toothed wing leading edge and high wing taper.
Stability in the wind seems quite good.

Overall, I am very pleased with the design/quality of the Spark.

Regards,

Andre Bouchard

Status: offline 		Hi,
I'm hoping to put a Plettenberg in my Spark - does anyone have a good outline of the former that I will need to fit in the nose? Also what material do you recommend for this former? I am planning a carbon/ply/carbon sandwich.
Thanks
Colin
