彭大你好!
我想請教一下，在我飛3A的這些時間裡，明顯的感受電機在強風的穩定性比油機差(翅膀的晃動)，不知您那兒有看到這樣的差異嗎?還是選手們會使用兩架飛機呢?或是使用不同的裝備(更換馬達、槳)?我是選擇後者，亦或是他 ...
Hi Joy,
我也來囉嗦兩句, 希望您不介意。
其中一個可能的原因是飛行速度。一般來說，在平靜, 低風的天氣，您的飛行速度可以較慢，但在大風天，你可能須要嘗試加快飛行速度，以幫助對風的penetration。
以我的飛機, motor, prop combination來說, 21x14 是我最喜歡的槳, 他可以到每小時20英里 (32km/Hr)的風速, 如果風速在快, 我會換20x15的槳以增快飛行的速度。如果您平常用的是22x12的槳, 您可考慮在大風天時嘗試一些更快的槳, 看看更快的飛行速度是否可以幫助您的情況。
至於電機在強風的穩定性, 彭大已經提到, 抗風性與電機或油機沒有區別。以我最直接的經驗, 我的 CARF Integral 先是用170DZ, 後來改為電機, 飛行的特點和穩定性仍然是沒有任何區別的。
最後，你介不介意我用英文？如果可以的話, 這將節省了我多很用翻譯機來copy and paste的時間。
Hi Joy
If you don’t mind, I would like to add a few comments as well.
One of the possible causes to your question is the flying speed.
Normally, in calm weather, you can get away by flying slower speed, but in windy days, you might want to consider speed up the flying speed to help penetrate into the wind.
One common thing people do is using faster prop in extremely windy days.
You should experiment different props to find out what is the best combination that fits your style of flying under different weather conditions.
In my motor, plane, prop combination, I like APC-e 21x14 as my best all around prop, with 21x13.5 as a close second, they are good up to 20mph wind, more than that, I will change to 20x15 to gain more flying speed.
If you are using 22x12 prop in normal flying, you might want to try some faster props in windy days to see if having faster flying speed helps your situation.
As Dr. Peng mentioned earlier, there is no noticeable difference between flying electric and glow.
I have flown the same plane (CARF Integral) using 170DZ at first and later converted to electric, however, the flying characteristics and stability remains the same.

，免得模糊了彭大分享的這個主題。
