    ROC HOBBY V TAIL BUILD GLIDER

    I have selected the Roc Hobby Glider as my first platform. Hope it is a good choice.
    Starting from the ground up.
    The FPV System I am ordering is :
    Ready Made 1.3 ghz system
    Control Will be :
    72 mhz

    I have attempted to attach pics. Hope it worked.
    Please check it out. I am open to all the guidance I can get.
    I will be ordering from Ready Made RC in the next day as I will be rolling out to Ireland for work. 10 long days dreaming about and researching.

    Welcome

    With first platform, do you mean you've never flown RC before? In that case i would suggest flying line of sight (LOS) first, or even start with a simulator to avoid dissappointment. And don't fly too far with that 72mhz. It's easy to lose track of distance and time in the beginning of fpv, and before you know it you'll plunge to the earth.

    I made this video some months back with an inexpensive HK camera.

    After a 2 week haul in Ireland and a bag swap in Denver (home) a week in Mexico.
    I am home to unbox my XP9303 w/ 649s rx Fm72mhz.

    Will the esc plug into the rx directly?

    If the esc has a standard servo type connector it'll work just fine. I'm sure it does.

    What's an EagleTree 1.3 ghz system?

    My bad for the typo. Jet Lag is a real thing.
    I got the FPV package from rmrc.

    Cutting Time

    Decided to put the 72mhz 649s rx in. Hogged out a pocket.
    My thought was to run the antenna out the side and back toward the tail.
    Would it be better to run out on the wiing?
    I am having trouble with the throttle.
    I plugged in the esc to the thro. port on the rx.After a minute or so the motor kicks in and runs at about half speed.
    Need to figure that part out.
    Downloaded the XP 9303 manual so I can try to make the V tail work properly.

    I Passed the t-2 exam. Wish I would have done it when was in A&P school a bunch of years ago. Piece of Cake. I had an instructor at Colorado Aero Tech that thought he was in another planet. more than Half the class failed electronics. I barely passed. I continue to struggle with the electrical physics of some of it. I am not much on being a ham guy. (no dissing to the group that propagate) I don't want to be stuck in front of a radio. Prefer to be doing the wild thing with a hottie. Or Flying a fpv. I haven't done the later yet. So The build Goes on. My Wife of all people wanted to go to the Testing with me as she carries all my gear for me. She suddenly decided she want's to take the test.She will take the test when I do the general exam.I am a lucky guy. I think. I have a co-pilot with benefits. hahaha. Seriousy this girl is a mathematical genious. Sometimes she freaks me out when I am in my toy room working on my build. I have to go thru all details of my plan with her.We end up on the floor and nothing gets done. BOTTOM LINE. PASSED easy test. Have Co Pilot with Benefits LOL

    Just a few tips:
    First, you picked an excellent first plane. I had a 2m Phoenix2000 as my first "successful" airframe and loved it. Very forgiving, and long flight times. They dont like to come back down, so make sure you have a large flat area to land in.

    72hmz out the tail is the way to go. Limit the antenna to one bend if possible. Swap it out with a tuned 1/2 wave or longer if you can, and just let it trail off the back of the plane. After your ground tests are finished, your maiden flight should be done with your TX antenna shortened at least one section at first, and when you start to reach the limits and you notice glitching, extend it to full length to regain control and come back. That will establish your link range.

    Definitely ditch that stock 1.3ghz video antenna. If nothing else, they are bulky, draggy, and add weight, but their performance is marginal at best. Being new to FPV, definitely consider a set of CP antennas. They are relatively forgiving to make yourself at 1.3ghz, but sourcing supplies can quickly add up to more than buying your first set. You should have plenty of range on omni's at first.

    Follow the Denver guys on this thread. There's a lot of people flying on 1.2&1.3ghz in your area, so you may want to coordinate with them so you dont loose your video mid flight because someone else in your area powers up, or vice versa.

    Welcome to the LAB! We have a strong group of folks on here from the Front Range. We are planning a meet sometime near the end of May, it's a great time, and an invaluable learning experience.

    Beat it to Fit Paint it to Match

    Thank You For the Advice. I am for sure looking at canning the rubber duck. I went to the IBCrazy site. Reading all I can there. Seems to be the antenna guy.

    Excellent Idea for the half wave on the rx control. I need to Go back to my book to do that.
    Should I match the same gauge wire?

    I made some more hacking to mount the vtx.
    Hope it is not to close to the rx.

    Now I am Back in The Republic of Ireland Cork. until the 28th. Bum Kon.

    I got a e-mail from a FPV guy up in Galway the last time I was here. I will try to meet up. Rains and rains and rains here.

    Thanks again
