Which ESC to replace my XP7A
I had an XP7A ESC withSteve PCB and HP05 motor for my MCP X, but I recently tried plugging in a battery which I didn't realize had reversed polarity and it seems to have fried either my Steve PCB or ESC. I am not sure which is the issue as neither has any visible damage.
The problem with the setup is when I connect a battery the ESC beeps several times very quickly then does the 123 beep indicating it is initialized and ready. But when I give it throttle the motor doesn't spin. The manual says the short beeps coincide with the number of cells but this is a single cell battery so it should beep once. Anyway, I don't understand the details of picking out and programming an ESC. So I either need something that is plug and play or that is at least solder and play. I don't mind soldering, but I need something that comes per-programmed. I suspect it is the ESC and not the Steve PCB that is damaged so if I could get another XP7A that is already programmed for the MCP X I wouldn't be against that option as long as it is at a better price, than one that doesn't require the Steve PCB. So far I have looked at the Hawk Creations 10A ESC and the Oversky 10A esc. Both look to be plug and play and don't require soldering and run about $35. Are these good options? |

I don't like any ESCs for mcpx except the lightest weight ones. In my mcpx world every extra gram is enemy. I control one HP05 with a double FET XP3A.
What do those other ESCs weigh? XP7As are light and plugs for Plug-And-Play are heavy. Here is a $9.65 0.7gram ESC: http://www.hobbyking.com/hobbyking/s...ontroller.html I can set up a plug and play ESC for you. I would add a Blheli flash plug. You could program with Blheli--change motor direction, gov speed, etc without any more soldering. You would need a Blheli tool--$16 at Astroid Designs. $35 is a lot of money for an ESC.

And it looks like it comes with the MCP X style signal and battery plugs already attached to make things easier. Unfortunately there is little information on the ESC's on the product page, not even a brand name. Someone in the discussion said they were running BLheli software on it, and someone said there was a flashing tool for it, but I am not sure where to buy it, since no name or model # was mentioned. This ESC business is so confusing and daunting. From what I have gathered the process goes like this: 1. Determine if ESC will work with your heli out of the box or if it needs to be programmed first. If it will work out the box skip to step 6, otherwise continue to step 2. 2. If the ESC needs to be programmed first, determine if it is a SiLabs or Atmel based ESC. Use this information to purchase a compatible flashing/programming adapter. 3. Determine how to connect or solder programming adapter to ESC. 4. Determine correct version of BLheli or other software? 5. Determine correct parameters/settings to program to the ESC. 6. Determine how to connect ESC to Helicopter. Which parts of the ESC need wires soldered to which parts of the Helicopter, or is it plug and play? The problem is finding the information necessary for completing each step. |

I'm right there with you. I have a mcpx bl that I have put a hp06v2 and hp03 tail that I have built up. I can handle all the soldering and everything. Now I'm just down to getting esc's and programming them with the blheli software. It seems like an almost insurmountable bit of work to do for me but I will get it if it kills me lol.
I was going to use the xp7a for the tail, but having to do the fast mod to it has put me off of it. Looks like I might go with the HK 10a airplane one. I still have a bit to figure on to get it all sorted out. In the end I think it will all be worth it and hope to have a helicopter that rips holes in the sky with a rock solid tail. Replacing tail motors has been my biggest frustration.

Well I overspent on my ESC and got an Oversky 10A ESC off EBAY for $35, but it came pre-programmed for the MCP X (or so they claim). It doesn't seem to have soft start programmed, so that's annoying. Also I am having trouble with over-voltage protection being activated on the MCP X's 3n1. I had this problem a lot on my brushed MCP X's but rarely on my brushless one with the XP7A so that too is a bit worrisome. I managed to reduce the instances a bit by adjusting the main gear mesh, and raising my idle-up throttle a bit. For some reason the over voltage protection seems to activate more often the lower I set my idle up throttle curve which seems strange.
I managed to track down the flashing adapter for it which just plugs directly into the ESC for $10 from HobbyKing, so that's cool. I am going to go ahead and get it and program it with BLheli. Hopefully governor mode will help with this over-voltage issue. What's funny is the $15 ESC from Hobbyking from my previous post is the exact same ESC I paid $35 for, just under a different brand name and not marketed as plug n play for the MCP X like the other one. I kind of doubt there is any difference at all between the default programming of the two but oh well. Bottom line I am getting there. |
