Hello Everyone,

This is Max Current 5mm to 4mm Bullet Reducer.

This is a pack of two Max Current 5mm to 4mm Bullet Reducers. These reducers are great if you typically use 4mm bullets, but happen to have a LiPo with 5mm bullet holes, and don't want to put 5mm bullets on your ESC. Instead, install these reducers into the 5mm hole in your battery, and now they're compatible with a 4mm bullet connector.

If you are interested in,Please feel free to contact me. Thank you!

Best Regards,
Catherine Chen

Hi, my name is Katia Landauer. I am the daughter of Timothy Landauer, an active member of this forum who passed away in 2019. I have been going through my dad's old RC boats and there are just too many-- is there anyone who can help me sell some? I'm a little lost on this site; any help would be appreciated! Please message this account if you have any suggestions, or message me on fb messenger (Katia Landauer).

AGFRC 66KG IP67 Waterproof Digital Servo High Torque Programmable 12V Full Metal Gear Brushless Servo for 1/8 1/10 RC Models, Control Angle 180

Comparing the two versions of A80BHSW and A81BHMW, this SA86BVMW version uses 12 volts, which makes this servo can work under higher voltage (11V-14V), and the maximum torque of the servo is increased to 66KG. Furthermore, the battery line and signal line are separated, the 3S LiPo battery line can be directly connected to the battery, and the signal line uses a spiral structure line with stronger anti-interference.

The strength of the bearing is improved, and the collision resistance is stronger, making this SA86BVMW servo more suitable for applications in 1: 8 scale RC model such as off-road and climbing car, 1/8 1/10 Buggy /Monster Trucks/RC car/boat/plane/helicopter/robot, etc.

SA86BVMW servo is also a member of AGFRC PROGRAMMABLE SERVO, equipped with AGF-SPV2 servo programmer (included) which can change the torque, speed, angle, and other parameters of the servo what you want, even 360 full range angle or 720 angle, etc. It's really convenience for users to DIY the parameters of their servo according to the situation.

Moreover, the manufacturer will continue to UPDATE the various firmware of the SA86BVMW servo, users can download the updated file from the manufacturer's official website to update it through the AGF-SPV2 servo programmer in the future.

How can I calculate curising speed for my uav ?
Posted by fastmax | Yesterday @ 12:05 PM | 2,236 Views
Had a set of NOS Sauce motors that needed put to use so figured it was time to slap together another Whoop With this build I decided to go with an NBD Cockroach frame, and Goober canopy bundle.

I also had an older BeeCore F3 flight controller just sitting in my drawers so in it went. While I was ordering the frame and canopy I thought I might as well try out some of NBD's Azi props, and I also grabbed a few Nitro Nectar 250mah HV batts since they were on sale.

Just finished getting it set up in Betaflight, and got the batteries all charged up so now it's time to take it out for a maiden flight. Video, and DVR footage coming soon.

I will post some pictures of the nearly finished shop. I purchased the steel shop shell back at the end of 2016. Construction didn't start until early 2017 as I had to reorganize the area of the backyard where the shop was to be built. This included moving a shed I had built to hold the power tools and gardening stuff; it's size is 10' x 14', unloaded, turned 90 degrees and set on a new base of blocks. but before that I had to dig up the power I had installed years ago. After all of that my older brother and I used his survey equipment to lay in the shop floor. He also brought over some small equipment to dig the foundation and footings for the shop. The local concrete company came in at great expense and formed, poured and had the concrete done all in one day. They even added more rebar and added fibers to the mix and made it much much better than the plans called for.
After the concrete cured, I layed the base plates done as per plans. Then my older and younger brothers along with my father came over and we had a shop raising party. My father was more of a foreman than laborer, anyways it was great that he was there.
I will start with some pictures of the shop nears it's completion and then as I dig up more photos add them for posterity.

This is my Second Flight with the E-flite UMX Citation Longitude Twin 30mm EDF BNF Basic.

E-flite UMX Citation Longitude Twin 30mm EDF BNF Basic Second Flight (5 min 0 sec)

Here are my Review Notes for this E-flite UM EDF Citation Jet:

Pros:
- Lots of lights all over it
- 3S Brushless Twin 30mm EDF's
- Chromed out plastic on the EDF inlets
- Plastic bits on the wingtips
- I will use it as a nice warm-up jet, perfect to slide into my car on the days I fly big jets like the E-flite Su-30 EDF Jet.

Cons:
- Dented foam on the main wing
- One of the mains was bent out of the box, but easily fixable
- Some glue leaked onto the silver part of the chromed out plastic on the EDF inlets

I finally got around to finishing up this video that I started about 6 months ago. Long story but I don't like FRSky's options for monitoring your onboard voltage using a balance port sensor. I prefer an 'inline' connection that is permanently wired to your ESC. There's nothing to forget or plug in wrong when you go to fly your airplane/sailplane. A few years ago someone made an after market sensor but it was discontinued.

This project will explain how to make that discontinued sensor using an Arduino micro-processor board. You can make these sensors for about $10 each after the upfront cost of buying a programmer and some wires which will run you a one time cost of about $20.

I had to make this video to help simplify the entire process of programming and soldering up that board. When I was reading some threads on RCG I found out there was no good howto. Many of us (including myself) have never used / programmed an Arduino board and probably most have no interest in it.

This video will explain downloading the software, programming the card and how to configure OpenTX to use a voltage sensor.

A big thank you to Mike Blanford for writing that code and making it available for us to use.

All the parts you need are in Youtube description area.
