Now that's a build you have going Derek. Looks great. Thanks for sharing

[Derek]

I'm pretty impressed with the wing. I just wish the weather would warm up and dry out a bit because I'd like to set the plane in the yard and set the wing on the fuselage so I could take some pictures. It's just been so cold lately, I really don't enjoy being outside at all.

[Graham Lawrie]

WOW thats one very impressive build Derek:)

[Derek]

Thanks very much, Graham! Its coming along pretty well.

[Derek]

Finally, some outdoor pics

Now that's some sweet, quality work you have going on their Derek. Looks like it's coming alone very well. Awesome job. Keep up the good work and pics too!

[Stambo]

Hey it's me
That thing is huge, I would be too scared to fly it after all the work, in case I crashed it.

[Derek]

Lol...im scared already and the plane isnt even built yet lol

[Derek]

Im hoping to begin installing the flight controller and the Crossfire Diversity rx this weekend. I need to find out how to set up PPM because the Crossfire will output 12 channnels via PPM.....i need 11 channels lol.

[Graham Lawrie]

Sounds good Derek:)

PDB Installed.jpg (92.13 KiB) Viewed 5797 times

I just drilled the holes for the PDB/FC and added some standoffs. I've dropped the PDB into place. The fc will stack on top of the PDB, obviously. I'll have a Castle 20amp BEC Pro mounted a few inches in front of the PDB. The BEC should be quite enough to power all the servos. I think the Crossfire Diversity Rx will get mounted in the next compartment, rearwards. Now, I have a GPS unit to think about it's placement. What are some things that I should think about for GPS unit placement?

[Derek]

grrrrr, it just hit me that the Crossfire Diverisity rx, although will output 12 channels via PPM, isn't going to work for my Gemini build. There will the the throttle, ailerons, elevator, and rudder that get outputted from the rx to the fc and then the ailerons, elevator, and rudder servos will operate off the fc. However, there isn't an output to operate the servos for the air brakes, cargo droppers, and FPV pan and tilt. Bummer!

So, it looks like I'll be using the FrSky X8R receiver that came with my Taranis because I've seen videos on how to get the X8R to operate 16 channels. Channels 1-8 will be done via SBUS and the other 8 channels will actually operate via PWM from the rx pins.

It looks like I'll have to find another use for the Crossfire Diversity rx. Again...bummer!

[DOG]

You got to be kidding. That's a shame that you wont be able to use the crossfire. I know you were looking forward to use that set up. Good luck with plan "B" Derek. Just a mild bump in the road.

[Graham Lawrie]

Unlucky Derek:(
