Since I have flown the Zephyr II and ZXL and loved them, when Ritewing released the Zephyr 3, I knew I was going to have to buy it. It has the fantastic flying characteristics of the Zephyr and ZXL with the payload space/flexibility that I have always wanted. I should say at this point I do not have personal experience flying it, only youtube/vimeo videos.
My hardware setup is as follows:
Any changes to my hardware setup during building etc will be discussed below and reflected here.
I have used a couple of different Turnigy Aerodrive motors with the Zephyr II and ZXL but wanted to go with a smaller and lighter motor for the Zephry 3. I considered:
- Hyperion ZS 3014-12 but at $130, the efficiency gains were not worth the price.
- Eflite Power 25 1250kv (which I already have) but its a bit on the heavy side.
I finally settled on the:
Turnigy Aerodrive 3536 1200Kv (111g)
I have always used the Turnigy Plush 80amp ESC in the Zephyr and ZXL because they are the same weight as the Plush 60amp. I decided to use a Turnigy Plush 60amp as I had a new one and only used Turnigy Plush 80amp ESCs.
If I am going to run the 3536 1200kv, I need to keep the current draw reasonable. I could use a 9 or 10 inch prop but since I have some Turnigy wood 9x6, I am going to use them as I like the wood props more than the plastic APC props.
I learned long ago that stabilization works much better with faster servos, similarly to how upgrading to SimonK firmware makes multirotors more stable. The Zephyr 3 can take both Standard and Park size servos and I already have a couple of different choices in both sizes. In the interests of keeping weight down I will be using the Bluebird BMS-393DMH servos.
I would like to get approx 30 mins flight time. I have the Turnigy Nanotech 5000mah and 6000mah 4S batteries available.
There isn't really a choice on this one, I am using the Quanton.
1.3Ghz 400mw video transmitter with Mad Mushroom antenna
MinimOSD as the OSD. I would love to use the Draco OSD - viewtopic.php?f=21&t=154
GoPro HD Hero (version 1) as both recording and live camera with battery removed to save weight.
I have a ground station built into a pelican case. It receives the 1.3Ghz video and retransmits it on the 5.8Ghz frequency for my goggles.
I would love to use a combined radio and telemetry radio. I am aware the OpenLRS can do both and I have the modules for it but I feel the telemetry speed and options for the OpenLRS are limited. I would love to use the RFD900 but there is no option to use them as a modem and receiver, which I think is a real shame. If I ever get the time to combine the OpenLRS with the RFD900 I will be using this option. I also have the EzUHF and will probably use that for manual control.
