LitterBug's ZOHD Altus VTOL build

[LitterBug]

I believe Litterbug will have his maiden flight before I get all the *options" figured out tested and implemented. I'm moving at a snail's pace because I've never done a flight controller and some of it is almost overwhelming, but I'm too stubborn to say **ck it and buy the ready to fly version.

Some "ready to fly" aren't any better than what you are going through. Even some of the $$$$ ones are a mess and should have never been called RTF. POS... Pile Of Stuff after maiden.

I have weather to deal with here. I am also 99% sure the motors should be replaced before maiden, possibly the ESCs too. I need to hook my FC up and see if the ESCs are proprietary or if they can be reprogrammed. If they are propeietary, they should be replaced. I'll check the tail first since it was pinned rather than direct soldered. Would have been tough to pull the ESC through the tail boom. LOL. I also should have checked the direction on the front motors before assembly. If they need reversed, and they are proprietary, yet another reason to replace. I would rather have full customization than to have to work around odd ESCs.

Both Flysky FS-i6X & Radiomaster TX16S have the following completted:

Arming works via switch AND rudder stick. Still working on that.

Modes now working on 3x switch.

Servos still not working.

Delay of Game:

Servos will NOT activate. Working back & forth with Heewing. Only 2 of the 3 motors will run. I've swapped motors, escs an ports and it comes down to only 2 working motors. Looks like some type of exchange will be needed or I can find someone to solder the SpeedyBee I have as a spare. Gonna talk to the club at next month's meeting.💩

Let the Games Resume!

ALL issues resolved. Really a case of RTFM. I missed a 5v connection from the PMU to the controller. That resolved the servo issue. The 3rd motor is the rear motor and in forward flight mode it does not activate. ABSOLUTELY GREAT SUPPORT from Heewing.

Woah nillie! You are going to force me back in action. Gotta dig my FC out tonight. The motors and ESCs swap can wait! LOL

This is what I plan to use

I am in your shadow, just trying to get to a new level. Advice requested.

Was going with Bronco, but wondering if one of the following might be better:

FT Cruiser
FT Explorer

The Game is still on.....

Good sign, I had 3 30A ESCs all ready to go in my parts bin. 3-6 S capable too..... Have the motors I've been contemplating too... SunnySky 2207 2100kv. Can also get them on clearance for $6 a pop in CW and CCW variants. The motors I already have are on a stalled quad (quint) build..

In following a guy doing his work on getting a VTOL to work said this, "YOU ARE GOING TO FIND OUT THE LIFESPAN OF A VTOL MODEL IS VERY SHORT."

You are presuming anything I fly has a lifespan not measured in minutes...

Are you doing a thread on your build?

Just hanging out here. 1 good day and then a week of cr@p trying to fix whatever somehow got screwed up. Had all 3 motors running, servos moving as expected and decided a good time to shut down and get some sleep. Next morning, Mission Planner will not connect to the flight controller and I've been fighting that for 3-4 days. 2 different windows computers, one Ubuntu with Mission Planner and 3 different esc cables and nothing works. I think somehow the Ardupilot instance on the flight controller got compromised or I screwed up on the config and I haven't yet found a way to connect. Hoping Heewing can reflash if needed.

I went thru what you are going to do. Especially when you program it. Get the wrong value, sign direction, wind gust, transition and one wrong reading and it can fall out of the sky. I chose bi-copter and it is very hard that two props have to handle all three axis .

It might be a good idea to start your own thread....As this is @LitterBug's thread👍 I am just sitting back and watching how you guys fair, and then when I find out what works then I will give it a try!🤣

I have flown quite a few Tricopters and planes with FCs. It is easy to test everything on the ground to make sure the control reactions are configured correctly. What usually bites people the quickest is having a reaction backwards so when the FC tries to correct the flight it ends up flipping rather than correcting. Been there, done that. The transition is all I haven't done. Testing both modes of operation is a must. It is possible to fly each mode individually as well without the transition.

Mmmmm.... NEW "old stock"!

Going to upgrade the ESCs and motors this weekend during SnowMageddon. They are calling for 8"-12".

HECK of a good deal for $90. 4 motors AND individual ESCs. Picked up the last set BuddyRC had. Perfect for those who need independent ESCs with no BEC, 2 CW 2 CCW. VERY hard to find single ESCs like these any more. So upgrading Motors from 2204-1850KV to SunnySky Racing 2306 2300KV. Proprietary ZOHD 30A PWM only ESCs with BECs to SunnySky 30A Blheli_S ESCs that can run just about any protocol and no BEC. Have an FC with BECs so no need for them on the ESCs.

Cheers!
