【問題】YW24汽油引一問

tienyao

有誰用過YW24這棵汽油引擎,重量只有860G,淨推力7KG,不知推120級的機子
是否還有停懸的空間?.....有經驗的可否分享一下嗎?

ENGINE BREAK-IN OIL AND PROPELLER SELECTION

BREAK-IN: The engine should be installed in an aircraft and flown to help with the break-in process. This allows the engine to be loaded and unloaded using the throttle and will also help with cooling.

Refer to the propeller chart below. Recommended propeller sizes are for aerobatic flying, and may vary depending on your needs, altitude, and conditions.

BREAK IN OIL AND FUEL:We recommend the use of a petroleum-based oil, such as Lawn Boy Ashless, at 50 to 1 for the break in of all YW engines. This period takes about 10 gallons of fuel.

Use standard 87 octane unleaded fuel for break in and after.
The motor will not perform as well on hi-octane pump gas or AvGas.

DO NOT use a synthetic oil for break in as the rings will not seat correctly and the maximum potential of the motor will not be realized.
這是我從YW網站看到COPY下來的資料.
磨合注意事項:
我們建議使用石油基潤滑油. 比例為1:50 不建議使用全合成潤滑油. 而且他建議使用辛宛直87的汽油. 太高辛婉值(台灣最低是92)引擎會表現不良.......

我裝在 David Patrick Ultimate 雙翼機上,  搭配過
APC16x8,  Menz17x6  & Menz18x6,  油門反應靈敏
電子點火供電可用4~6c或兩顆鋰電.

台中 陳信旭 有裝在 一米七五的CAP上, 搭配
APC 16.5 x 12的槳.

因為引擎總重與120級同, 所以裝到40cc的飛機
要注意頭會較輕.
