Charging 1s lipos is a pain, they typically last 3 minutes give or take so you can go through some batteries flying in an afternoon. Charging them 1 or 2 at a time is a pain and takes forever. If been charging them either parallel or serial which is better as you can charge 6 at a time. Serial you have to have 6 batteries with the same capacity and about the same state of discharge. With parallel you charge up to 6 of the same capacity and discharge state.
Picked up a UP-S6AC which charges 6 1s batteries the difference being is that it charges each battery independently so they can be any capacity or discharge state. It will charge both Lipos and LIHVs and at the same time. I set it to .3a charge rate which shouldn’t hurt any of the batteries I have, it can be set from .1a to 1.0a the charge rate is the same across all 6 ports. After testing it to be sure it was operating correctly I modified it to charge my batteries with the new BT2.0 connectors. It has on each port a micro Losi, PH1.25, PH2.0 & Jst (converted to BT2.0).
I can’t figure out why I waited so long to buy one of these chargers at $27.99 from RaceDayQuads it was well worth it. Don’t think my iCharger Duo 410 will be getting much use when it comes to 1s batteries.
Turned out to be an interesting afternoon. Was out flying the Shutterbug85 on the 2nd battery I was doing rolls & got it bouncing off tree limbs. Finally came to rest on a limb, disarmed, armed hoping to be able to fly out of harms way. Instead it hit the ground upside down & would not turtle over. 😩 Walked down towards the back end of the yard. Luckily when I built it I put a beeper on it, so I could flip a switch & hear it. Went back to the house to look at the video to get a better idea of where it was, no video the sad card wasn’t all the way in. 😞
Went back down & looked some more, still nothing, so I decided I needed to go down it the creek to look for it, so back to the house to get my hiking boots & Jackie. Gave Jackie the radio & I went down in the creek. From down there it sounded like it was on top. Kept having her trip the beep & I chased the noise. Finally decided it was coming from the other side of the creek so I started climbing the far bank. She beeped I listened finally I was getting closer. Finally saw it laying on it’s back against a tree. Getting out of the creek sucks so I decided to walk the fence looking for a way over or through. Down between the 2 strip centers I found a gate. So I started waking back. Got to Steak n Shake & my sweet wife turned the corner to pick me up. Hope I don’t go through that again. At least I found it. 😊
Been thinking about camera drones for awhile they always seemed pretty cool but were rather expensive at least for me. Recently Dji came out with the Mavic Mini which is a small drone with good specs but it also lacks some nice features that the Mavic Air has but then the Mavic Air is almost twice the price of the Mavic Mini which sell for $499 for the Fly More Combo kit while the same FMC kit for the Mavic Air goes for $1149. I did find an open box Mavic Air for $765 at Micro Center but didn’t have the cash to buy it and I couldn’t talk the CFO into funding it. I’ve been selling off RC stuff that I no longer use trying to get the cash. Well low and behold last Saturday I can across a good deal on a used Mavic Air FMC including a set of ND filters for $550 so I grabbed it before someone else did. Sometimes you just have to be in the right place at the right time. Now I’m waiting for the mailman to drop it off at my door. According to tracking it should be here Friday Dec 27. 2019. Was out of my control but I missed maybe 4 good days for flying. Still got a couple before it turns back to winter. So while I’ve been waiting I have been reading the Mavic Air thread on RC Groups and watching Youtube videos trying to learn all I can about it. Still the best thing will be stick time,
