Hi guys,

I'm looking for some user experiences with the micropilot products. I've found some threads related to the heli version of the MP2128, which did not look very promising and convinced me not to try integrating it. However, I cannot find any recent threads or user reviews of the fixed-wing versions of these. Since Micropilot aims mainly at fixed-wing, i find that somewhat surprising. Do any of you have recent experience with one of these on a fixed-wing?

Thanks

Jean-Philippe

Hi, I worked on a MP2028 and a MP2128 for around 6 months for my project. I am not exactly sure if there are newer version of hardware, firmware or software since I got everything as is from my school.

The biggest issue that I had with micropilot was getting the license key for the horizon software and technical support. For some reason, the horizon software that came with both the 2028 and 2128 requires applying for a license key everytime you install it onto another computer. It is free, but you will have to wait for it everytime you need it, which I think is pretty stupid, considering that it should have came with the mircopilot itself.

Technical support was always available, but due to time zone difference between me and micropilot, my team always had to make the phone calls and wait for email in the middle of the night. I am not so sure about your time zone difference, but do take that into consideration. Apparently, it seems that tech support does not go to work on time either. However, when you do get them, they are always helpful and willing to provide solutions.

The MP2028 that I had NEVER worked even after months of fiddling. The horizon software for that requires me to land the plane everytime I need to make any adjustment to the pid gain, which I think is really stupid and time consuming. I didn't know that technology allows you to actually adjust the PID values in flight until my prof got my team the MP2128 which uses a newer version of the horizon software.

The MP2128 takes a lot longer to initialize and load the flight files, but it is way better and most importantly, IT WORKS. In hindsight, my team could have made the MP2128 fly well within a month or two, if we had started with it.

Micropilot claims that their autonomous system is light and compact and stuff and I can honestly tell you, THAT IS BULL. That is just the main board. There are a whole lot of other things that you will need, including their provided BIG AND HEAVY modem which is like twice the size of the main board.

There are newer autonomous system that claim to be adapative and are probably easier to work with than the MP2128 at the same price that we are paying for, but bottom line is that the MP2128 does work on a plane.

Hi, thanks for the comprehensive reply.

From what I understand the MP2028 and 2128 are only different in processing power. Do you think the differences you have experienced between both are only caused by the difference in software version? Doesn't MicroPilot provide software updates for the 2028 which make it equivalent to 2128 functionality? Do you know the purchase dates (years) for both modules more or less? Speaking about the weight of the equipment, they do use their systems in cropcam, which is a lightweight electric sailplane... So I suppose there is improvement on that front as well!

I am not so sure what caused the differences as I have no knowledge about autonomous system. My project was more of implementing the system, rather than research on autonomous system. As for the update, I am not too sure either, you have to check with micropilot. I know the horizon software on the MP2028 that my team had wouldn't work with the MP2128. I didn't have a chance to test the MP2028 board with the newer horizon software as we killed the MP2028 in a crash...which was what lead to us getting the MP2128.

We have the cropcam(or rather, HAD the cropcam) in our lab. Yes, it is using a micropilot too, but the modem on that is not what micropilot supplied us with. The 2.4ghz transmitter on the cropcam is like half the volume of the standard range transimitter that micropilot supplied with our MP2028. What we were unhappy with it was the misleading 28g advertisement. We thought it was going to be tiny and light, but apparently the 28g is just the main board itself w/o the other required accessories and servo connector board.

I am not too sure when they were purchased.

With the MP2028, we just couldn't get the plane to follow the waypoint after 3months of trying, but with the MP2128, we succeeded after a few trips to the field. We had problems like nose dive, circling around different places(that were not in the way point) and inability to maintain altitude. You need lots of space to test the micropilot, or I suppose, any autonomous system. Be mentally prepared for crashes if this is your first attempt at autonomous.

Hi,

What was your exprience with the cropcam? It is using 2028 too. Was it reliable and in working condition right out of the box? What were your general impressions of it?

Thanks
