A gyro for early and intermediate flight CSM have always been committed to providing high-performance products even for inexperienced flyers. So for his latest project, CSM's chief designer Dr Colin Mill has decided to upgrade the SL310 entry-level Dual Mode gyro. Colin has also responded to the increased popularity and affordability of digital servos. We have always recommended that flyers use high-speed tail servos if possible, and we're glad to announce that the SL310 will now support both digital and conventional servos. Servo speed is also the motivation behind the cutting-edge Second Integral Heading Lock feature. Second Integral is the new Heading Lock - instead of controlling the rate of rotation, it monitors the heading and actively corrects it, increasing the pressure on the tail if it fails to respond quickly. Previously, servo speed has placed a limit on the effectiveness of any gyro, but Second Integral can compensate for lower servo speeds. We still recommend a fast tail servo when possible, but, for beginners, pairing the SL310 Micro with a slower servo is a very economical option. Frequently Asked Questions for Beginners

Model: The SL310 Micro is recommended for 30- or 50-size helicopters. Belt driven models: we recommend painting or spraying an anti-static spray on the back of the belt to protect your gyro from static, one we particularly like is Graphit 33. Radio: The wiring is compatible with JR, Futaba, Hi-Tec, Graupner, Spektrum and the current style (blue plug) Sanwa/Airtronics transmitters. If you wish to use the SL420e with any other make of radio, please check with the service centre in your country, or email CSM's technical support on tech@csm-ltd.co.uk The gyro requires an auxiliary channel with travel adjustments to control the gyro mode/gain. It cannot be used with basic RC systems that lack such a channel. We recommend that you use an RC system that also provides travel adjustment on the rudder channel. Most current production computer RC transmitters have these facilities. Servo:
The SL310 Micro can be used with either a digital or a conventional servo.
Batteries, power consumption and wiring: Due to its two stage power supply regulation, the SL310 Micro will accept a supply voltage range of 4.1v to 7.2v. Please note that your RC system may be more restrictive.

If you haven't used a CSM SmartLock gyro before, these are some of the features which might be new to you: Quick Setup: Quick Setup is a simple routine which gets the gyro up and ready to fly. You enter it by toggling the gain switch back and forth whilst the model is on the ground. You then set the Gyro Sense, Digital or Conventional servo and Servo Travel Limits using your transmitter sticks. The gyro will also automatically pick up your stick centre and information about your radio gear. Quick Trim: Quick Trim is a simple method of correcting for any small linkage errors. Toggle the gain switch five times whilst in flight, and the gyro will correct the trim. Please do not use stick trim when flying the SL310 gyro as it may cause the stick centre information to become inaccurate. Dual Mode switching: Two modes are available: Second Integral SmartLock and Standard. SmartLock is an enhanced version of heading lock, whilst standard has the characteristics of a conventional gyro, but with Yaw Rate Demand to allow for fast turns at high gyro gain levels. The gyro gain channel is used to control these modes - the gain switch switches between the two modes in flight, and the travel adjust (ATV) of the gain channel is used to adjust the gain in each mode. Optional digital servo support: In Quick Setup, the gyro can be set to work with either digital or conventional servos. Second
Integral: Unique
to the SL310 Micro! Second
Integral is the new Heading Lock. Instead of locking the helicopter to
the desired rate of turn, it monitors the helicopter's response to actively
correct heading errors. This gives stronger holding power with slower
servos.
Set-up Model helicopters are made with extreme precision and small inaccuracies in assembly and set-up can cause poor performance. Most problems with tail control are caused by the set-up of the tail or by the gyro being sited in the wrong place. If you are new to RC Helicopters, please follow the tail set-up instructions in the manual carefully. It is best to ask a more experienced modeller to check over your model after you have assembled it, as mistakes can cause the helicopter to go out of control and pose a danger to yourself and others.

Please do not be alarmed if the gyro behaves differently on the bench from the description in the manual.
