In this article I want to talk a little bit about battery connectors. Battery connectors - you wonder? Yes! What might at first sound like a boring topic with not much to say, turns out to be a quite interesting one, especially when it comes to brushless whoops.
Every mechanical connection is a place where electrical energy can be “lost” - or to be physically correct - translated into heat. You want your plugs to be as lossless as possible, so that all the energy can reach the place where it should be used - mainly the motors.
The iFlight Alpha A85 is the big brother of the A65. As the name suggests, this one is 85mm from motor post to motor post. And is capable of recording HD footage to the onboard DVR.
The quadcopter is advertised as “Indoor” - I don’t really think that this is true for any 85mm quad, except if you really have a big indoor space. At least for my apartment, 85 mm is way too big. I mean, I can fly it - but it is simply no fun. In a bando on the other hand, this is obviously a different situation - any place that you can explore, you will have a lot of fun with this one.
Thinking about building a 1S brushless whoop and you are not sure which AIO flight controller to use? I want to show you a couple FC’s which I think are viable choices and explain what I am looking for in my 1S flight controllers.
Obviously there is no ONE perfect flight controller, otherwise this article would be pretty short. It depends on what you are looking for, and this might be different for everyone. I will show you what I look for and how my decision process looks like.
The Alpha A65 is iFlights rendition of a 1S, 65mm whoop. I was very excited to see an iFlight whoop since I usually really enjoy their ready to fly products, like the Green Hornet Cinewhoop which I reviewed a couple of months ago.
Their products are usually very well thought out and super solid. Spoiler alert: The iFlight Alpha A65 is no different in that regard. But let’s see what exactly it brings to the table.
The GEPRC Stable 12A stack is intended as an all in one solution for toothpicks and microquadcopters.
Being an AIO, it is flight controller and ESC in one board. But this is not all - it would not be a stack without the video transmitter. The flight controller does not come with an onboard SPI receiver, so you have to provide your own receiver of choice.
When I first saw the Geelang Wasp85 on Banggood I thought: “Ah something different” - I want to take a look at that. Bangood was kind enough to send me one to check it out.
I was hoping that it is a bit of a sleeper and surprises by just being plain awesome, unfortunately that was not completely the case.
The total weight is 46.5g without batteries and 63g including two 300mAh, 1S batteries. I like to fly it with GNB 2s, 450mAh batteries and with those it weighs in at 75.2g.
The Tramp Nano is ImmersionRC’s attempt at a nano sized video transmitter - but this one is different in a couple of ways. First, and most importantly, this video transmitter is capable of an output power of up to 500mW (25, 200, 350, 500mW).
The Flywoo Goku TX-Nano is a nano sized video transmitter and weighs in at just 1.4g without antenna and 2.3g including the antenna. The solder pads are very spacious and easy to solder to. Those are definitely the biggest pads I have ever seen on a nano sized VTX.
The VTX can be switched between 25, 50, 100, 200 and 450mW. Power and channel can be switched with the on-board button or via IRC Tramp protocol.
The BetaFPV M02 VTX is BetaFPV’s newest addition in the Nano VTX segment. I always liked the BetaFPV VTX’, because you can connect your FPV cam directly to it and from there wire everything to your flight controller - it is just a way cleaner setup in my opinion.
The M02 has a couple of very interesting tricks up its sleeve, some features that I have not yet seen on any other video transmitter of its size.
