Tricopter 1.5版 Since the Trunigy 302 gyros doesn't work well with my Futaba FASST receiver I decided to try using 4 Hobbyking HK401B gyros instead. 
I noticed on the old 401 gyro I had that the PCB inside of the case wasn't secured properly so before mounting the 4 new gyros I took them apart and secured them a little better.Here is how to do it; 我注意到在旧的401陀螺我有这样的案件的印刷电路板里面没有安装之前将获得4我把他们分开，并取得他们一点better.Here是如何做适当的，所以新的陀螺仪;
Unscrew the 4 bottom screws and lift out the PCB. 拧开螺丝4和摆脱底部的电路板。
If you want to be absolute sure that the cables aren't stressed and break in a crash, use a bit of hot glue to secure them to the PCB. 如果你想成为绝对确保电缆不强调，打破崩溃，用热胶位，以确保他们在PCB上。
To secure the PCB inside of the case use a small drop of hot glue in each corner of the case and while it's still hot place the PCB in the case and push it down until it's fixated. 为了确保案件的印刷电路板里面使用的情况下在每个角落，小水滴的热胶，虽然它仍然是热的地方在PCB的情况下，推动它，直到它的迷恋。
To make absolute sure that the PCB will remain fixed I used an extra piece of foam between the lid and the PCB. 要绝对确保印刷电路板将保持不变我用了一个盖子之间和PCB泡沫的诱惑。 Now screw the case together and you're done. 现在拧在一起，情况就大功告成了。
Since the HK401 gyros have a bigger footprint I needed a slightly bigger frame. 由于HK401陀螺有一个更大的足迹，我需要一个稍微大框架。 But instead of making a totally new one I simply made a modified top plate. 但是，而不是一个完全新的我只是做了修改顶板。
Futaba FASST receiver mounted. 双叶FASST接收器上。
All done! 全部完成！
One thing I noticed right away with the new gyros is that do not arm the ESC's. 有一点我就注意到了与新的陀螺仪是不公平的调速器。 This is because they do not give a valid signal during the start up initialization, this makes the ECS's think that you have an FM receiver without a valid signal and the ESC's goes into protective mode. 这是因为他们不给初始化期间开始向上有效信号，这使得精英的认为你有没有一个有效的信号调频接收器和调速器进入保护模式时。 Which is to say they will not initialize until they are restarted and get a valid signal. 这就是说，他们不会初始化，直到他们重新启动并取得有效的信号。 But if I was to restart the ESC's the gyros will reboot as well since I'm using the built in BEC's of the ESC's and were back to square one again. 但是，如果我是重新启动调速器的陀螺仪将重新启动，以及因为我使用内置的选委会的调速器的，并再次回到了起点。 To solve this problem I made an external BEC to “jump start” the receiver and gyros; 为了解决这个问题，我做了外接式BEC到“快速启动”的接收器和陀螺仪;
When I plug this external BEC (with a diode in series with the possessive output, just to be sure) into a free channel on the receiver and then connect it to the balance connector on the battery, the BEC will only power the receiver and gyros. 当我插头（用与占有欲输出系列二极管，只是为了确定）到接收器上的自由通道这种外部选委会，然后把它连接到电池上的平衡连接，选委会将只功率接收器和陀螺。 After the gyros have initialized I plug in the main battery connector, powering up the ESC's. 陀螺仪已初始化后，我在主电池连接器插头，通电调速器。 Now the ESC's get a valid signal and boots up just fine. 现在，调速器获得一个有效的信号，并启动后就好了。 I then remove the external BEC that I used to “jump start” and can now enjoy my flight. 然后我删除外部BEC的，我用的“快速启动”，现在可以享受我的航班。
Time to fly! 时间飞了！
It flies! 它飞翔！
Comparing the old Turnigy 302 gyros to the new HK401B , the HK401B's are much more sensitive to vibrations. But once you get rid of the vibrations the HK401B's perform a little better than the 302's. 但是，一旦你摆脱了振动的HK401B的表现比302的好一点。 It feels a more locked in and even more stable. 让人觉得更锁定，更稳定。 The HK401B's also work in digital mode, unlike the 302's that made the whole tricopter jerk horrible in mid air at random times. 该HK401B的也可以在数字模式，不同的是302的，使得在随机时间整个tricopter挺举在半空中可怕。 But the best part is that they work great with my FASST receiver. 但是，最好的部分是他们的工作与我的FASST接收机很大。 I'm happy that I tried the HK401B's. 我很高兴，我尝试了HK401B的。 |
