The new CL_SPU_USB + BLDRV3 driver cards
replace the older BLDRV2-24 cards and are
now recommended for new systems.
A limited number of older
CL_SPU & BLDRV2-24 cards
are still available for customers who wish to add cards to
their existing installations or as spares/replacements - please
contact me for details.
modular brushless motor driver for self-build flight control
The CL_SPU_USB and BLDRV3 cards must be "engineered" into
a properly designed and constructed Control Loader (FFB) system. Please read
all the project information listed on the
and FFB Yoke page BEFORE
Please email me if you have any
The CL_SPU_USB & BLDRV3 cards are available as
special order items (despatch is typically 1 to 2 weeks following order).
To order cards please email me
at the email address below indicating the number of cards
required and the destination country. For small number
orders I will then send you a PayPal email invoice detailing
the total cost (including standard airmail delivery to
non-UK destinations). Secure payment can then be made
using the links on your email invoice..
For a single pilot
station installation, 1 x CL_SPU_USB is required, PLUS 1
BLDRV3's - one for each flight control axis (motor).
(So, for example, a single flight yoke will
typically require 1 x CL_SPU_USB + 2 x BLDRV3's. The CL_SPU_USB
can support up to three (3) BLDRV3's to allow a rudder
axis to be included.)

BLDRV3 card - GBP 99.50 each + P&P
(For customers requiring the older
cards please email me.)
For overseas orders P&P will normally vary between
GBP 15 and GBP 20 (including
insured airmail to non UK destinations where available) depending on the
number of cards ordered. UK delivery P&P will be about
There is no VAT payable on these
orders as BFF Design Ltd is not UK VAT registered.

Customs or other import charges/duties on deliveries to
non-EU destinations may be incurred - I am not able to

IMPORTANT - Technical
I am able to provide a
reasonable amount of free email technical support for
card customers. However there are practical limits
on the total amount of support time per order the relatively low sales
price of the cards can cover.
For non-commercial home-use customers I
can provide, free of charge, a cumulative total of two
(2) hours of technical support time per order.
Subsequent technical support
time will be charged at a rate of UKŁ40 per hour (for
support provided during normal office hours).
If you feel you may need more than 2 hours of technical
support time then please contact me before ordering cards.
Please read all the project documents and satisfy yourself
that you can manage the work required in building your CL
controls BEFORE purchasing cards and attempting the project.
Despatch: is usually about 1 to 2 weeks after order placement; I'll let you know if
there will be any delays before ordering. Note each card is
made and tested to order and this takes a bit of time.
Terms & Conditions: Please read the
Terms and Conditions
BEFORE ordering. Please read the important note above on
Delivery Times: Typically 5 to 10
working days after despatch - however this will vary with
destination and the usual delaying factors (holidays,
customs, local conditions etc).
NOTE: I normally supply the
driver cards only; to complete the
project you will need to source for yourself all other components
required for the system.
I am not able to confirm if
brushless motors other than those specified in the
plans and documents are
suitable for use in a CL system. If the motors you wish to
use do not have sinusoidal back-EMF characteristics it is
unlikely that they will provide smooth enough force feel. I
can't tell if they have these characteristics without
physically testing them.
The CL_SPU_USB cards have a "Discover" mode
of operation which can be used to identify appropriate
EEPROM settings for non-standard 3 phase motors - contact me
A BFF CL Software
non-commercial home-use licence is included with the price of card orders
(one per pilot station).
To unlock the software on a specified PC you must run the
software then follow the registration prompts and email your
PC ID to me. I can then send you the unlock key for that PC.
Please contact me if you wish to use the BFF
CL drivers and software for commercial projects.
