如何改裝09仔ENGINE

有見比賽在即,開此POST為一些不懂改裝的作支援,請多多分享

I share 1 point:

the intake of carbutor is too small...the original is 4mm in diameter

it is recommended to enlarge the diameter from 4mm to 4.5mm....Please be reminded that dont enlarge the diameter too much...it will affect the stability in slow speed.  4.5mm is enough ga na...

師兄, 有冇比賽 details o既 link 睇睇?

永利SPADA盃及1/10油車公開賽

no one willing share your method in 09 engine modification....too bad too bad...this is atmosphere in HK RC industry...

咪咁灰住....個post 唔係上咗好耐啫.....

不過我見過其他websites d 師兄改得好靚.

u meant rcstudy?

  haha.........呢度唔方便講嘛.....

To maximize its performance, please see see the following

1) There is no glow plug head in 09 engine. after installation of cylinder, the heat sink will be fixed on the cylinder's head. This design is very stupid. Once, u tighten heat sink screws, the heat sink will be deformed. Since the heat sink is directly attached onto cylinder, the deformed heat sink will also deform the cylinder.

2) u can check check this by the following method....unscrew the heat sink...tighten the heat screws again and rotate the crankshaft...u will feel that if u tigthen screws deeper, the knocking at the top of cylinder will be bigger...

3) Hence, to install 09 engine heat sink.....Please dont tighten too heavily....it will be much better if check if the crankshaft can rotate well enough while u tighten the screws....by few times dissemble and assemble, u shall do it perfectly

Dont regard this knocking as a good feature to RC engines....it is completely different from those people say the cylinder and piston is very tight
