Default **Digitech CRU** First Telemetric Retract controller for Jeti

Digitech CRU for Jeti

Central Retract Unit
Worlds first truly configurable retract controller with telemetry!
Designed by Carsten Groen, produced and sold by Digitech.
. Works on most available retracts (Electron , Behotec , JP , Digitech , Prolynx , Jet-1A , Mibo Jets etc).
. Power in/out easy to hook between your turbine or RX battery system (dual MPX connectors).

. Wirelessly Programmable Using DC/DS Tx Device Explorer
. Sequencer with 4 servo output channels (smart system will only work if wheels are in or out, dependent on status).
. Current is monitored (alarm can be set) for the 4 door servos, alarm if excessive current (blocked doors).
. Manual Pushbutton for gear up/down, can be mounted on fuselage (no need to turn on TX to control gear).
. Selectable Pulse braking (to avoid flat-spots).
. Anti Skid (we wanted to call it ASS “Anti Skid System”) but this was revoked by our department of seriousness )
. Gyro controlled brakes and front wheel servo.
. Independent braking by rudder movement, you get more braking power to one side when moving rudder.
. Delays independent of each retract for up and down, for scale purposes.
. Settable speed, max current, rewind time etc. for retracts.
. works with virtually ANY retract system.
. Status messages on transmitter (wheels in/out locked), error (LUA application available, courtesy David Mcqueeney).
. Front wheel braking possible.
. Upgradeable via USB connector.
. EX Bus jeti compatible (further TX systems pending).
. 3 retract output
. 3 brake outputs
. 4 gear door servo outputs
. 1 steering wheel servo output
. 1 manuel switch input (for gear up/down without transmitter)
. 1 Jeti EX Bus connector
. 1 Male Multiplex connector
. 1 Female Multiplex connector

For Jeti, fully EX Bus compatible, only 1 cable needed to your receiver.!
Full Jeti programmable thru Device Explorer menu.
Ideal for scale models, you can delay each gear in and out with time delays.
You can set every brake in Pulse mode and even control the braking force for left, right and front.
You can set the rewind time, min/max retract time, max current allowed (block detection) etc.
Works also with LUA application, full status for gear and brakes on one single easy-to-use screen!
Available end of year 2019.
Price 149,- incl Local taxes.

Technical details:
Input voltage: 6 to 14 volts
Max current for the 3 retracts: 4 Amp each
Max current for the 3 brakes: 3 Amp each
CNC milled aluminum box
Size: 69 x 45 x 17 mm (excluding connectors)
Weight: 50 grams (1.8 oz)

I have three of these CRUs, I cannot get the nose wheel to be gyro controlled. I've gone into the Jeti Device Explorer and enabled the gyro, but it's not compensating when the nose yaws left or right. What am I doing wrong with my setup? Thanks, Tom
