e-Mikado Logo 400 500 600 > Lockout

Today is the second time that I got lockout on my Logo 10. Using Futaba radio and ultimate BEC. I have 3 toroids, on input to BEC, output from BEC at receiver, throtle wire at receiver. Heli was no more than 50 feet away from me. I had been flying for about 1 minute. Anyone have any suggestions. I don't know where to start.

Lucky enough this time it only cost me a set of Modelsport blades.

Other equipment is Castle Creations 60 and hacker C50-13.
Futaba Gyro w/9253. Jr 3421 servos. Gyro and receiver are mounted on a 2" x 4" carbon platform.

Did you have your transmitter/receiver set to fail-safe mode? Did you do a range check before flying? I would suggest changing your crystal. I had the same thing happen to me 2 times before. Both times it would be flying fine then all of a sudden nothing worked and it crashed. I put it on the bench and tested it and everything worked both times. I knoticed it only locked out when I changed my crystal to a different one then I normally use, so I tossed that one and got a new one. It never happened again. Hope you fnd out what the problem is?

Take Care,
Cheers, Patrick

What he said. And did you install that little Tantalum capacitor on your motor that came with it. It is critical for stopping electrical transiets which could very well cause a lock out. Of course you have followed all the proper procedures for mounting and routing your recievers antenna.

I lost my infamous tag line.

Hmmmm.. I think this is only for a brushed motor.. He is using a CC Phoenix 60 and Hacker C50-13L.

My suggestion would be for you to make sure that the tail belt is tight, and to ground the tail boom, either to the negative pole of the battery or to one of the screws on the motor mount. Does it range check ok?

I'll second that. Ground your tail boom and check tail belt tightness. I ran a wire (you can see the green wire in pics in my gallery), from a shcs that i threaded into the tail boom under the gyro mount plate and grounded it to the motor mount.

Lockout

Radio check is OK.

What is the story on the tail boom ground wire? Is the alum tail boom with the rubber belt acting like a Van de Graff generator? This is the first I heard of it. I have two other friends that have the logo and their tails are not grounded for what thats worth.

How tight should the belt be? I did set mine a little on the loose side.

rchaas, where did you buy the gyro mount from?

Are there any other problems or cautions with the logo that I might want to watch out for?

Thanks for all the help.

Dunno about the grounding of the tail boom? I don't have mine grounded and it works great. Never had a static problem, so why bother doing all that grounding stuff for? My tail belt is on the loose side too. I use to have it really tight before, but it caused too much resistance so I loosened it.

Larry, check out my gyro mount. It has aluminum machined boom clamp.



BTW Robbie, nice looking Arizona Heli canopy you have there. I like the paint scheme you chose. I was thinking of ordering your design for myself. My g/f likes the purple on it, hehehe.

Take Care,
Cheers, Patrick

Your tail boom is carbon fiber which may act differently form the alum.

Nice gyro mount.

Its a mikado part and can be purchase anywhere that sells logo parts...ie. fxaeromodel.com, rcdirect.com, etc.

A number of people (but not all!) have reported ESD leading to radio hits from the rubber tail belt and the aluminum boom, which they have taken care of in a number of ways, including spraying the tail belt with some kind of spray available at RC Direct, keeping it tight or using an aluminum tail (hard upgrade to get ahold of), but the cheapest, easiest, most definitive way to do it is to simply ground the tail boom. After reading a number of threads about this, i decided to ground mine up front, before any problems developed. Don't know if it helped, but i haven't had any hits so far!

Hi Patrick,

Thanks! I love the scheme, and it shows up in flat light really nicely too. My wife loves purple too, so there is that benefit as well

carbon tail boom

Does the carbon tail boom solve the problem with tail static?

I am with the others on grounding the tail boom. I couldn't even keep my Aveox motor/esc running more than 30 seconds on my Logo 20 with out gounding the boom. I converted a Raptor 50 and used a Hacker motor/esc combo and had several lockouts before I grounded the boom. I've got 10 hours on it without a hit.

It works

I grounded the tail boom to the negative lead of the battery and I had two flights today. The first flight was about 4 minutes. The second flight was 18 minutes. No problems at all. I even managed a few loops and rolls. it was a gorgeous day.

Thanks to everyone who took the time to post and share their knowledge, it helped a lot.

Thats great! Just remember, don't get to carried away and ground everything to the negative side of the battery. I have all my booms grounded that way, and it works great, but if you try to ground some motor cases to battery ground there could be trouble. Some of the cases are hot. As in they have voltage. Kind of sounds like I tried that....right? I've seen people tie the frame to the boom to the motor and I thought I'll tie it all to ground. The case to the ground lit up like a light bulb filliment.
