昨天小小停懸跟航線了一下, 因為引擎還在磨合期, 所以沒有給太多的pitch
半對稱的槳飛起來只能說很穩很穩, 而且升力很足夠, 玩熄火降落非常過癮.
等磨合完之後會把MAH的810對稱槳放上去3D, 但是800拿來3D會不會有 ...

LS...我想並不存在誰盜用誰喔
不是不頂自己人, 但是據我所知, 在10幾通與helibug的電話裡我瞭解到
Helibug最早成立在2008, 從那個時候開始的600汽油改套以來, 一路都是Ali先生自己設計, 找工廠製作
他的700汽油 ...
I have the kit HB7-RC with the G270-RC. When I fly with the canopy the engine temperature reaches 135 degrees celcius. The servos also just above the engine get too hot to. When I fly without the canopy the engine temperature stay at 110 degrees celcius. Did you cut your canopy? You have a similar problem?
Are you baking or broiling servos?
What kind different with those flavor.
Same issue...
...cooking, broiling, boiling... same result!... a "flavored" dead servo and crash!

The airflow issue you are observing can be solved by building a carbon/glass plate and securing it over that hole in the plastic cover to ensure the air continues to flow over and out of the cylinder head area. You would also want to replace the stock can muffler for a pipe so that air does not deflect off the muffler and redirect back up into the canopy.
I personally solved this servo overheating issue by applying these 2 fixes. Without them you will most certainly cook the servos on a hot day.
I also cut the canopy a little high above the muffler to also ensure the air blows out past both the canopy and the muffler. It is a fairly easy set of fixes and just requires knowing how the air flows, where it flows and ensuring you get it redirect and carried out of the frame/canopy/muffler area.
It is real have lot of potential of hazard.

...........我不知道你這樣回帖挑出改裝機失控傷人傷財誰來負責這種言論的用意何在. 僅僅是分享一架直升機
你非要扯到這些地方來...
不過既然你提出了, 我也分享一下為什麼我能飛近200架次從來沒有遇到過問題:
1. 我不用引擎自帶的排氣筒, 因為那是車用引擎本身設計不在封閉空間(機頭罩內)使用, 改裝直機用排氣管把熱排氣往外導出, 可以防止廢氣進入頭罩內導致電子裝備升溫.
2. 亞拓離合器在木精引擎上很好用, 非常好用, 但是裝到汽油引擎上後會打滑一陣, 在高過正常轉速時才工作, 所以只能換副場摩擦係數高的離合器來令片, 跟較低轉速的離合器使用. 據我在600N上炸機數次的經驗得出, 若離合器沒有辦法正常工作, 離合杯的溫度會急速上升的很誇張, 有兩次摔斷油門連桿關不掉引擎導致離合杯整個磨不見, 然後引擎爆缸.
3. 在機頭罩與引擎散熱葉片重疊的部分開洞, 幫助引擎散熱
4. 儘管汽油機一缸油能飛20來分鐘, 每飛行7-8分鐘一定休息5分鐘降溫, 因為木精飛機本來就不是設計持續長時間使用, 更不要說換裝更容易發熱的汽油引擎了
不論今天這個改套是誰賣誰做誰販售, 這類玩家間相互交流非公司行號販售的的改裝套件部品在使用時, 我們這些使用者都是需要負有責任. 遙控模型不是玩具, 固妥善照顧並小心使用自己的設備才是王道.
