OPTIFUEL is building a highly respected reputation for developing products and accessories for the model enthusiast which now covers brands such as OPTIPOWER Ultra Guard 430 a new intelligent concept in model flight safety.

ULTRA GUARD 430 is a small lightweight easy to install smart landing system designed to restore total backup control allowing you to land your model safely following a main power failure. A welcome new development and additional safeguard is the easy to fit Ultra Guard high intensity LED Flash Alarm..

The device is plugged into a free port on your RX or FBL system and when you power up the device waits, monitors the system set voltage, then arms at that voltage less 0.5V. The device is then armed and monitoring the system voltage and the state of the buffer pack.
If the buffer pack needs topping up it will do that and balance it from the main packs or RX pack and stop when it gets to a nominal 8.1V. The device samples the system voltage every 2mS and if the system voltage drops below the armed set voltage then the buffer pack steps in if the system voltage recovers it drops out, this is seamless. The device when working can and does indicate locally that its operational and if it is charging or not but this is not able to be seen at distance.
A separate external high intensity LED can be fitted that shows you are on the buffer pack, this is an option and these can be cascaded if required. The device works across 4.6V to 8V.
The combo version (the board and buffer pack) are bound together by clear shrink wrap as is the super combo version (inc LED system).
The total weight is <39g inc LED <35g ex the LED. All parts can be purchased separately. The device can go to storage charge if its not going to be used for some time.

The new Futaba R7108SB is a compact and lightweight FASSTest 2.4 GHz receiver with integrated telemetry function. It is based on the well-known Futaba R7008SB. What is new about this receiver is that it also features the older FASST protocols, which can be switched directly at the receiver.

This means that this receiver can also be operated with older FASST systems. Due to the super slim design, the receiver is perfectly suited for models with narrow hulls. The R7108SB has antenna diversity and constantly checks the signal quality of both antenna inputs. This way the receiver switches to the better input signal in a flash and seamlessly.

Technical data:

•     Frequency band: 2.4 GHz
•     Transmission system: FASSTest / FASST
•     Number of channels: 8 PWM / 18 S.BUS
•     S.BUS output: S.BUS / S.BUS2
•     Voltage range: 3.7 to 8.4 V
•     Dimensions: 47 x 25 x 14,3mm
•     Weight: 12g

This is Ceramic Hybrid Ball bearings set. Its made to fit to Helicopter engines : OS 40/46/50/55- Thunder Tiger 40/46/53 Redline & Pro - Magnum 40/46, YS 50-56

Those bearings are rated for 250H of engine work

Those bearings might fit other engines as well

Hybrid Ceramic is the new Holy Grail! Its lighter, smoother, stiffer, harder, corrosion resistant, and electrically resistant. These fundamental characteristics allow for a wide range of performance enhancements in bearings. Ceramic bearings dissipate heat quickly, reducing friction and wear while maintaining a precision smooth surface. Today's leading edge ceramics are made with Silicon Nitride (Si3N4) and have characteristics similar to the heat absorbing, highly resilient tiles on the Space Shuttle as they protect it from the 2500 plus degrees F. extremes of re-entry into the earth's atmosphere. The use of Ceramics for bearing components results in a far superior product over traditional all steel ball bearings.

Set include 2 ceramic bearings, Front and Rear

The ceramic ball on the right is not only much lighter and impervious to corrosion, but also much more resistant to impact. Ceramic bearings earn their reduced friction due to much tighter roundness tolerances as compared to even the best steel bearings.

Instructions to use:

Front bearing must have 1 sealing. the inner part must Not have sealing. Sealings are very easy to remove with small screwdriver( wear glasses when working with such tools)

Rear Bearing( larger one) must be without any sealings. please remove if needed.

Hybrid bearings cangive you a feeling of "dry move", but once lubricated, they will be running smooth and almost without friction.
