Once again we go crazy on hot Saturday noon at 12.30pm buzzing around carpark with our small scale radio control car. PSP cam onboard NANDA NRX-18 touring car belong to Akiraceo our forum Member....yup the cam is heavy so the car was not in a good balancing mode. The one chasing from behind is my modified auldey mini-monster chassis equipped with HENG LONG AM 27hz receiver, ESC-Castle Creation 1/18 SIDEWINDER MICRO brushless system 4200KV motor, TOWER PRO 9G mini servo, PN Racing bearings and aluminum gears and lots of hop ups. Turning cheap toys into expensive jewel! As you can see NRX-18 uses Brushless system 6800KV motor value versus mini monster truck which uses 4200KV brushless motor. Both however equipped with the same ESC system: Castle Creation SIDEWINDER. Too bad i lose the race by 2 second. lucky i didn't put LIPO battery else that NRX-18 eat dust.

This is a cheap piper cub purchased online ready to fly for $70. It originally came with a 380 brushed motor and a strange controller that was neither mode 1 or 2. I upgraded it to a brushless motor and to my futaba 2.4 GHz Fasst radio system. The piper cub is great looking, but it is lacking in many areas. I would not suggest buying this plane for the first time flyer as the controller is not the conventional mode 2 type that is the most popular type among U.S. flyers. Save your money and buy the hobbico flyzone piper j3 cub for $150 that comes ready to fly with aileron control. Thanks for watching. Eric Jordon http://www.AroundTuitVideos.com

Consider this. The tail has to quickly respond on the commands of the gyro and the rudder/yaw commands fed by the user. A motor driven tail has to rely on "quick" motor speed changes for a responsive yaw control. Speed changes has to be "quick" on both spooling up (counteracting torque for a positive yaw) and spooling down (deacceleration for allowing the main rotor torque to take over for a quick negative yaw). The problem with a motor driven tail is that the speed change is not that quick as the tail has to "accelerate" or "deaccelerate" first before the desired speed is achieved. The acceleration/deacceleration factor is heavily dependent on the weight of the tail rotor blades and the motor's shaft and armature. With a "dual motor" mod , you achieve a quick speed change but still it has to accelerate and it also increases the overall weight including the armature thus the opposite yaw would be slower unless you apply some sort of "braking" mechanism in there in order to have the same quick response effect on spooling down. Some would even use a "brushless tail motor" or a ducted fan mod sort to speak but those motors need some time to accelerate and deaccelerate as well thus yaw control would still be a problem plus the fact the a duct itseld would even add a certain amount of momentum on the tail causing yaw overshoots and undershoots. Well, the best tail rotor response would still be a belt drive option as you will only deal with a constant tail blade rotational speed, and you would only rely on the pitch of the blades to counteract the torque and with these much quicker pitch changes, no acceleration/deacceleration factor will affect the perfomance of the tail and your heli's heading will be tight. But what about helis without a belt drive ? I am presenting this concept of having still a motor driven tail but with a constant speed and the yaw is still dictated by the pitch of the rotor blades instead of the usual motor speed changes. This video demonstrates this idea using a HoneyBee CP2 Carbon Fiber Tail mounted with 1100KV Brushless Motor. An ESky Belt CP tail assembly was used. The motor and BeltCp tail was mounted on the CarbonFiber Shaft using a CP2 Blade Grip/Holder. Build Log Here; http://www.rcgroups.com/forums/showthread.php?t=855814

Equipped with Castle Creation's Mamba Monster Brushless System Up to 25.2 Volts of Massive Brushless Power Includes New Traxxas TQ 2.4GHz Radio System with 4-Channel Micro Receiver State-of-the-Art Integrated Chassis Design Hard-Anodized TeflonĀ®-Coated Aluminum Shocks Top Speed: 50+mph on 6S Power! Built For Brushless We built the E-Revo for 6S brushless power right from the start. For other companies, brushless ready means just making some nominal provisions for battery and motor installation and letting the aftermarket develop the upgrades necessary to make it survive. Not Traxxas. We heard the call for more power so E-Revo was tested tough for durability with brutal 6S LiPo power and intense custom wound brushless motors. For the uninitiated, this extreme 50+mph motor and battery combination is ordinarily a predictable recipe for a box full of twisted and mangled parts. Not so with the E-Revo Brushless Edition. E-Revos driveline has been engineered to endure the kind of horsepower and punishment thats possible with todays motor and battery technology. It looks factory because it is factory, complete with a separate motor plate for clean, low-slung single motor installation. Castle Creations Mamba Monster Brushless System Built specifically to handle the rigors of large, power-hungry trucks, the Mamba Monster speed control is ready for 6S LiPo power with its massive 6.5mm gold-plated connectors, high-efficiency heatsink, integrated cooling fan and heavy-duty components. The speed control sends its power pulses to a Castle 2200Kv 75mm motor, designed specially for maximum performance and reliability with 6S LiPo power in torque-hungry applications. The aluminum motor can is machined to act as a massive heatsink, high-grade bearings deliver maximum efficiency, and high-strength Neodymium magnets give E-Revo brushless edition outrageous torque. To resist the twist, a beefy 5mm shaft transfers power to Brushless-Ready transmission. Traxxas TQ 2.4GHz Transmitter and 4-channel Micro Receiver All new for E-Revo Brushless edition is Traxxas TQ 2.4GHz radio system. Traxxas' proven ergonomic TQ design now houses spread-spectrum circuitry, eliminating the need for crystals and channels. Just switch on and drive; the 2.4GHz circuitry automatically locates an open channel for glitch-free operation. The new 4-channel micro receiver has an integrated link button for fast syncing with the transmitter. Low-CG Chassis Design Engineered by Traxxas, the ground-breaking molded E-Revo chassis sets a new benchmark for electric monster truck looks and performance. The E-Revo chassis combines art and function to deliver a lightweight, integrated, and rigid platform that maximizes strength and reduces weight. Scalable battery compartments accept a variety of NiMH and LiPo configurations to unlock E-Revo Brushless edition's power potential. By combining the battery compartments with the chassis design, the battery packs can sit low and close to the center of the truck, plus valuable chassis surface is freed up to accommodate the electronics for a clean layout. This keeps the center of gravity (CG) as low as possible and increases side-to-side agility by keeping most of the weight close to the center. Leading The Way There is no other electric monster truck like E-Revo. It embodies the highest level of creativity in design and engineering skill to create the absolute best in monster truck performance. E-Revo is the benchmark that could only come from Traxxas, the leaders in innovation and design.
