Other battery pack building materials such as plugs and connectors for RC models rechargeable battery packs. Radio Control Planes, Helicopters, Cars, Boats, FPV and Quadcopters - Hobbyking. MODEL MOTORS s.r.o. - modelářské elektromotory AXI, MiniAC, VM. Jeti Advance Pro controllers These controllers contain a sum of experiences accumulated during many years of development work on our motor control equipment.The Advance PRO controllers comply with all ambi-tious expectations of users and in connection with the new programming card ProgCard PRO they come up to these expextations.Several controllers of this family are equipped with BEC voltage control systems for receivers and servos.
Controllers with the labelling SB contain switch mode. BEC voltage regulators with a voltage of 5,5 V. Controllers without BEC are labelled Opto and must be operated with a separate receiver and servo battery as for instance 4 x NiXX cells or with an external voltage regulator like the MAXBEC. Controllers with the marking HS are special designs optimized for high speed motors (up to 200.000 rpm/2-pole motors). The programming cards are set for easy and fast adjustments of the ADVANCE control-ler family. AR.Drone tutorial : Gauth. Pcm9xii-foto. Quadrotor. Unlike most helicopters, quadcopters use 2 sets of identical fixed pitched propellers; 2 clockwise (CW) and 2 counter-clockwise (CCW).
These use variation of RPM to control lift and torque. Control of vehicle motion is achieved by altering the rotation rate of one or more rotor discs, thereby changing its torque load and thrust/lift characteristics. [citation needed] Early in the history of flight, quadcopter (referred to as 'quadrotor') configurations were seen as possible solutions to some of the persistent problems in vertical flight; torque-induced control issues (as well as efficiency issues originating from the tail rotor, which generates no useful lift) can be eliminated by counter-rotation and the relatively short blades are much easier to construct. A number of manned designs appeared in the 1920s and 1930s. More recently quadcopter designs have become popular in unmanned aerial vehicle (UAV) research.

Soldering IronThis is by far the most important tool that you'll need for obvious reasons. Buying a good soldering iron is a must for any RC hobbyist who wishes to play with high performance equipment. Not only is it useful for assembly battery packs, but also for installing power wires on electronic speed controls and motors. The two most important factors affecting soldering iron performance is wattage and tip size. The wattage is a figure that indicates how much electrical power the soldering iron is using to generate heat. The tip size of a soldering iron affects the iron's ability to maintain its tip temperature. For soldering batteries, I find that a soldering iron with between 40 to 60 watts of power and a 4mm chisel shaped tip works the best. 2.
On the topic of silver solder, I'll just leave it up to the readers to make up their own minds. How to Build RC Battery Packs. This article assumes that you have a basic knowledge of electronics.
If you don't, consult a local hobby shop for help before attempting this. One of the main reasons for building (or rebuilding) battery packs, other than the cost savings, is the ability to improve the connections between the cells so the current will flow more easily from one cell to the next with the least amount of resistance. Resistance causes the cells to overwork themselves and heat up. Heat is bad for battery life and performance. The hotter the pack is, the less runtime, current, and life it will give and have. Battery Pack Styles A common misconception about battery packs is that they are one very large battery when they are actually made up of a number of individual batteries, called cells, that are connected together to work as a single pack. Cell Connection Basics There are two ways that the cells can be connected together.
