Kavan Bristell B23 Bauanleitung Seite 4

10. Remove the connection board cover and hook up your receiver, servos
and ESC following the wiring diagram right. The receiver is to be secured
with a strip of double side foam tape or hook-and-loop tape to the rear
part of the cockpit. Deploy the antennas so their active parts were square
to each other (if you are using a receiver featuring diversity antennas).
Note: The kit is supplied with the connection board for ailerons, flaps, rudder
and the steerable nose gear so you can use even the most basic 6-channel ra-
dios to control your Bristell B23. If you intend to use independent control of
aileron and flap servos and an advanced computer radio, you will have to
replace the default Y-cables with four 25-30 cm extension cables.
The LED lights are only powered via the connection board; they are not
remote controlled in any way.
11. With your radio on, set the servos to the neutral position (sticks and trims
centred) and fasten the setting screws of the pushrod connectors on the
elevator and rudder servo arms. Perform the throttle range calibration of
the ESC as described in the attachment of this manual.
12. Attach the canopy.
13. Use medium cyano to glue the dummy antennas (Fig. 13) and Pitot tube
(Fig. 14) in place.
RC SET INSTALLATION AND PREFLIGHT CHECK
• Referring to the instruction manual of your radio carefully hook up the on-
board electronics.
• Once everything has been correctly connected, turn on your transmitter
and plug in the flight pack. Check the neutral positions and throws of all
control surfaces. If you needed to make the control surface throws smaller,
simply move the pushrod closer to the centre on the servo arm or move it
far from the control surface on the control horn. And vice versa.

The test flying and fine tuning is pretty much straightforward, there will be
no surprise for a medium-advanced pilot that is supposed to fly this model.

Programmable Electronic Controllers for Brushless Motors
Congratulation on your purchase of a KAVAN Line electronic controller for brushless motors. The
state-of-the-art KAVAN Line covers almost the entire range of electric powered planes flown by
a Sunday flyer. All the ESCs can be quickly programmed using your transmitter and even easier
with the optional KAVAN Card.
PROGRAMMABLE FUNCTIONS
1. Programmable Brake Setting (use the brake on for folding props applications only).
2. Programmable Battery Type (LiPo or NiCd/NiMH).
3. Programmable Low Voltage Cut-Off Type (power reduction or immediate shut down ).
4. Programmable Low Voltage Cut-Off Setting.
5. Programmable Soft Acceleration Start Ups (for gearbox and helicopter applications).
6. Programmable Timing Settings (to enhance ESC efficiency and smoothness).

CONNECTING THE KAVAN ESC
The speed controller can be connected to the motor by soldering directly or with high quali-
ty connectors. Always use new connectors, which should be soldered carefully to the cables
and insulated with heat shrink tube. Use only high quality connectors to connect the ESC
to the flight pack as well - 2 mm gold plated connectors (Pelikan Daniel #7939 or #7940) for
currents up to 20A; 3,5 mm (#7941), 4 mm (#7946) gold plated connectors or DEAN-T (#7949)
for currents up to 60A and 6 mm (#7945) for currents up to 80A. The maximum length of the
battery pack wires should be within 15 cm (6 inches).

• Check the direction of rotation of the propeller. If it was incorrect, simply
swap two of the tree wires between the ESC and motor or program the ESC
(refer to the ESC manual).
• Check the correct position of the centre of gravity (CG): 75-85 mm behind
the leading edge of the wing (Fig. 15). Adjust the CG position by moving
the flight pack - if you could not reach the recommended position, do not
hesitate to add appropriate amount of lead to the nose or tail. An extra
couple of grams won't spoil the flying characteristics - but the incorrect CG
Expo
position is a killer.

• Fully charge your flight pack and transmitter batteries, check the proper
35%
function of your radio and perform the range check of your radio accord-
30%
ing to its instruction manual. The range has to be almost the same with the
motor off and at full throttle (no more than 10% decrease is acceptable). DO
NOT try to fly unless the range check is 100% successful.
Plug the UNI servo connector cable of the ESC to your receiver throttle output. The ESCs
featuring BEC or SBEC voltage stabilizer will feed your receiver and servos from the flight
battery pack.

Battery
Please bear in mind improper polarity or short circuit will damage the ESC therefore it is
your responsibility to double check all plugs for proper polarity, and proper connection
BEFORE connecting the battery pack for the first time.
POWERING UP FOR THE FIRST TIME & THE AUTOMATIC THROTTLE CALIBRATION
The KAVAN ESC features Automatic Throttle Calibration to ensure the smoothest throttle
response and resolution throughout the entire throttle range of your transmitter. This step
Dimensions
has to be performed just once to allow the ESC to "learn and memorize" the throttle output
(mm)
signal of your transmitter. It only needs to be repeated if you changed your transmitter.

The throttle has been calibrated now and your ESC is ready for operation.
NORMAL ESC START-UP PROCEDURE
1. Move throttle stick to bottom position and then switch on transmitter.
2. Connect battery pack to ESC, special tone like "123" means power supply is OK.
3. Several "beep-" tones should be emitted to present the amount of lithium battery cells.
4. When self-test is finished, a long "beep-----" tone should be emitted.
5. Slowly move the throttle stick up, the prop should start to rotate clockwise (looking from
the cockpit of the plane). If it spins in the opposite direction, pull the throttle stick back,
disconnect the flight battery and swap any two of the three cables between the motor
and the ESC. The re-check again.
