FX K3DC

Image
Hudy family present new engine. As like as OS,it has square bore,3 port. And crank shaft is coated with DLC. Why is FX engine's block color silver. Other brands is black. Is there difference on production? I think big 3 heatsink is more thin and sharp. Engine block strength is important for stable rotation. But surface area should be more vast.  And cooling should effects more on exhaust area.

Servo new line up

Image
In winter season each brand offer new servo at model shows for next season. High end servo need high torque and high speed moter and full aluminum body. KO is a Japanese brand. They are good at servo system. And KO servo is only made in Japan. They use core less moter not brush less. It goof for torque and stable. Now I use RS2 KO servo. I recommend KO for servo products. RS3 response HC 17.6kg 0.06s 7.4v For steering  RS3 power HC 31.6 kg 0.11sec 7.4v For throttle. Sanwa is a Japanese brand. Sanwa design and develop in Japan and made in China. They are good at radio control system. They never raise problems. Well proven product. I use Sanwa transmitter. SRG BX type R 19.8kg 0.09sec 7.4v For steering and throttle. Futaba is a Japanese brand. Most biggest company in the industry. They have OS engine brand too. They are good at electrical devices. I have never used their product yet. I can't decide their products.   S9353HV 22.0kg 0.06 sec 7.4v  

wing

I put new wing. It's a jconcept finisher. I like jconcept wings. These have durability. Lexan wing have most durability on all. It's a punisher. These have low rear flips. Then on against wind jumping make stable.

PICCO V1 TEAM DLC CER

Image
Picco unveil new off road engine. I've got Picco last year model. One of difference point is engine block. Old cooling fin is block type. Like a REDS. New one is round type. Like a TRITON. Like a OS. It has three needles. New carburetor has idling needle. Old crank shaft is not coated. New one is coated with DLC. It needs high quality. OS often missed coating on crank pin. Can Picco keep that quality? Left is a old Picco. Right is Triton.  New Picco cooling head as same as Triton. It has nine fins. RC car engine is the most simple engine. But there is place for improvement. OS engine suggest four break through. First is square bore. Second is three needle carburetor. Third is DLC crank shaft. Fourth is Low cooling head. Picco follow second and third.  I want to try one.

Fail safe

Image
RC driver have to avoid unable control radio system. Not only our car is broken not also another people hurting is terrible thing. We usually check receiver low voltage setup. Do you check trancemitter low voltage? For example airtronics has fail safe setup. CH2 is throttle servo. Default setting is free. But you should set hold status. If trancemitter was on low voltage,servo holds neutral. On no registration engine stay maximum throttle,engine easily broken.
