SRX8

I’ve remained one colore on the body. The vivid red is needed to spray several times. And to need drying each time. Srx8 body has not thickness for lightening. Then easy to break. I’ll paste glass fifer on backend.

I disassembled OS engine. And Checked primary components. I found two hit points on pistons. There are same position on both side. This position is piston pin guide on backside. It is different position of thickness. Then the position is more expand than others. Should be more warm sleeve by heat gun on first fire. Crankshaft has no scratch. Bearing has rust. If it remained fuel it calls rust. I have to replace one. I order ceramic bearing and carburetor cover.

I have finished big project. It took away all time for playing RC. I will enjoy GP buggy again. But  I  have not maintained for a year. First  I checked starter box. My box is made of  FRP. Connection belt is broken. I changes new one. Battery is available yet. Electric system is OK.

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.

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  

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 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.
