I have a 65mm tiny whoop that started life as a US65 but really is now a custom with the US65 name. It has a Meatec411RX FC, SE0802 22000kv motors, 4 blade Gemfan props, Wolfwhoop AIO camera with a BetaFPV Caddex EOS canopy.
Decided to try Project Mockingbird for the Mobula6 on it, which is now using Emuflight instead of Betaflight because it has some features in it for Whoops were as betaflight is more for 5″. I’ve tried PMB before but didn’t really like it on anything I tried it on including the US65. I believe this was because it had Patrick Clark’s rates which were more for racing. My indoor space is to small for a racing tune, I need a cruising gap shooting tune. The PMB project for the Mobula6 is still in beta but is still pretty flyable. The bad this is that all the chatter about it is on FB at least that is where Patrick hangs out to help and answer questions. It was stated that the base tune was a little twitchy but he also had suggestions for make it less twitchy if you didn’t like it.
I put PMB on my US65 it it flew okay but not really the feel I like, it handled pretty good but was twitchy and floaty too. Using Patrick’s suggestions I have it flying pretty but it’s still just a little floaty. I’ve been tweaking then flying then tweaking some more. I think now I just need to fly several packs without making any changes to get a good feel for it, which is hard to do when you are changing something on every flight. Been doing this all with 350 mah GNB 1s lipos with BT2.0 connectors.
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. 😊
