    Hobby King Not safe to deal with

    I ordered a $12 ESC programmer. It just keeps beeping once. None of the buttons, (up, down, left, or right) work. Just single beep, wait, single beep. I sent in request for RMA. This is what I got back. We are sorry to hear the items you have received in order xxxxxxxxx seems to be...

    I got bit, badly...

    Sorry to hear about mishap, but glad the damage wasn't worse... Probably a stupid question, but after landing and having the throttle down, what happens if you turn your radio off? Or maybe disarm and then turn radio off? I am interested, because I might do the same thing if my battery...

    Lipo fire Always charge outside lesson learned.

    I'm thinking of taking a old outdoor gas grill, cleaning it up and ridding it of the propane hardware and leaving it on my patio. When I want to charge, roll it 15'-20' feet away from the house and turn on the charger. Any pros or cons to this idea?

    Hoverfly Tried the competition...

    I have been following the HF threads here for a few months. When I log in, I see 10x as many peeps on the DJI boards. I'm about 80% done with my first build (x8 or xy8 whatever it's called). I'm building around the HFP based on what I've been reading about quality of flight for filming &...

    My brushless gimbal result

    that's impressive. Sounds like their might have been a little wind. Do you think your motors will handle a gh2, gh3, or 5d mark II? What's the latest on getting the Alexmos controller? Are you planning on selling the motors for peeps to make their own gimbles? Are you going to be selling a...

    Hoverfly Futaba 8FG & HFP

    HFP manual says to set the travel adjustment channel 5 gear (on the spectrum radio) to -25% 25%. If I go into the end point on the 8fg, I get limit travel travel limit 135 100 100 135...

    Hoverfly Futaba 8FG & HFP

    Esc's programed and checked my vibration on my motors. Changed my mind on soldering everything, so waiting for 50 2mm barrel connectors to come, hopefully tomorrow. In the meantime, I'm have spent some time with 8fg manual, hfp manual, and the 8fg itself. Mucking my way through the setup...

    Lipo fire Always charge outside lesson learned.

    Wonder how Boeing feels. They have billions of dollars on the grounded jets and on hold in production with battery problems. Some built and some yet to be built. Something about the cells not being isolated enough. from nbc news "U.S. investigators have already examined the...

    Lipo fire Always charge outside lesson learned.

    I'm just starting and this is the stuff that scares me. I just got in 2 sets of 4s 5000mAh batteries (2 brands). I bought the iCharger 306b. I built my own power supply from an old pc power supply. For my first charge for just one battery, I put it on a small metal table in my driveway (it...

    Hoverfly Winter Flying

    Thanks. I think your probably spot on with the longer arms being slower and better for video and shorter being quicker and maybe better in the wind. Mine will be a bit wierd looking with teh arms going out past the motors, but I figured it would be fun trying the different lengths. I'm...

    Battery & iCharger 306b related questions

    From the 306B manual. Measuring internal resistance of the battery In general, the internal resistance of a battery is not a fixed value. It varies over time as the battery loses energy and also varies depending on the load, or how much current is drawn from the battery. One of the urgent...

    Battery & iCharger 306b related questions

    Your saying if you just go to 4.18 instead of the 4.20, that should increases the life of the battery? I really don't see a need for me to charge at 5C, but was thinking in the field if I take a generator or have access to AC power, there might be occasions when I want to charge 1-2 batteries...

    Battery & iCharger 306b related questions

    No comments because ? 1. Peeps don't use icharger 306b? 2. Dumb questions or not worded very good.? 3. Viewers don't know answer? 4. Subject too long and complicated for quick answer? 5. I should figure it out myself or call dealer?

    Battery & iCharger 306b related questions

    Just looking to verify what I understand are a few basics about charging lipos. I'm hearing lots of warnings and have decided to look for some guidance on the charging of lipos. I am starting with four 5000mAh 4s batteries. 2 are 30C and 2 are 40C. Max charge rate on both is 5C. I'm trying 2...

    Hoverfly Futaba 8FG & HFP

    About 2 different types of batteries to try, 2 each so I have 4 batteries and they all have 8 gauge wires. Not use to working with that big a wire. I did some soldering today and the EC5's were grate with a couple 12 guage wires, but were somewhat of a bear on the 8. Finally developed a bit...

    Hoverfly Futaba 8FG & HFP

    I initially was going to go with the ec5 but changed it sounded like more peeps liked the deans and they were trouble free. Guess I'll spend some more internet time looking at connectors this weekend and then having to order another/new para board for my charger.

    Hoverfly Futaba 8FG & HFP

    I deleted post cause I found answer in Manual. What a concept! On another note, what a pain in the butt soldering deans connections to 8 gauge battery wires that come on the 4S batteries!
