  Stripped Heads for Spark Plugs
Posted by: jimwitkowski - 10-31-2019, 01:14 AM - Forum: Fuel and Engine - No Replies

        If you haven't stripped out your spark plug threads in the head of your MZ202 your lucky. Because of the head being aluminum it easily strips out if the spark plugs are over tightened. There was a video of an air that had a plug pop out while the helicopter was running on the ground. Had it been in the air it would of lost compression and come down. 

I am selling the "Time - Sert" tool for installing steel inserts into the head to eliminate the stripped threads. Don't let repeated replacement or removal of the spark plugs weaken the threads and have the spark plug come out while flying. Dwight or Mike Messex can explain why the time-sert tool for installing the steel inserts are important for the safety of the MZ202. 

The inserts are available on amazon. I don't remember what size I bought for the MZ202. They cost approx. $2.00-3.00 each on Amazon. Dwight or Mike M. can tell you which size is needed for your MZ202. 

The kit comes with the brochures for installation instructions and all insert sizes. 

I no longer own my Mosquito XE so I don't need the tool anymore. I am selling the tool for $40.00  It was used once, its still like new.

Contact me if interested. The best way is to text me, as I don't answer unknown phone number calls. I can be reached at 414-610-1777

  A quick check-in request
Posted by: Daryl - 10-21-2019, 06:47 PM - Forum: General Discussion - Replies (4)

hi all,

I hope everyone is doing well.

Since the new forum has come on line, there has not been much activity.  I'd like to ask that everyone reading this reply with a quick update on you Mosquito status.  If you building, how far along in the process are you.  If you flying, how many hours do you have on your ship and how often are you flying.  

For me, I hope to own a Mosquito someday.  In the mean time, I'm reading the stories and enjoying all the videos that have been posted.

Best wishes!

Can someone please tell me what the "break pressure" is for the check valve in between the main fuel run injectors
and the needle valve on the collective.

  Maximum Horsepower and torque?
Posted by: Dave W. - 08-22-2019, 03:01 AM - Forum: General Discussion - No Replies

Could anyone say what the theoretical maximum horsepower and torque are for the Mosquito XE airframe? I am not asking about maximum airspeed. Thanks.

  Small things can have huge consequences!
Posted by: Casey - 08-07-2019, 10:10 PM - Forum: Abstract (not related to Mosquito) - Replies (3)

Hey everyone! So it's been pretty quiet around here so I just kinda thought I'd share something interesting that happened at work. It's not directly related to Mosquitos(hence why we're in the abstract forums), but the lesson learned can still be applied to lots of aspects of experimental helicopters!

The setup: 

This morning at my place of employment(a small controls and electrical shop) my duties involved helping an engineer of one of our customers conduct a rated current test on a rectifier bridge to be used in a hydro plant as a generator excitation device. Basically in this test we connect a large AC transformer that will supply low voltage but high current to the input of a large rectifier bridge, and we short together the DC output side so that current will flow. We bring the unit up to the maximum current the unit is rated to run at(I.E. 400 amps DC in this case) and let the heat build up and just verify the unit will indeed operate properly at the stated current.

The procedure seemed to be going quite well, however, we began smelling every electricians stomach-knotting smell, burned electrical components! So let this be the first lesson we illustrate here: whether you're flying helicopters, cooking bacon or conducted a rated current test on high voltage equipment, if something doesn't feel, or perhaps in this case, doesn't smell right, then stop what you're doing, shut everything down and figure out what the problem is or just reschedule! If you're gut is telling you something is wrong then chances are pretty good that it's right!

Anyways, that's where this story should stop, but unfortunately, we're not done. After a little investigation that yields no indication of the cause of the smell, the engineer decides to proceed with the test. I don't mind because afterall: A. It's his equipment, so if he wants to assume liability well that's no skin off of my back and B. while it is a very high current we're only running 10 volts AC so the chances of a dangerous arc flash situation are almost non existent. So we continue.

Not surprising, 10 minutes latter the alarms go off and the unit trips and what was once just a hint of a burning smell has now turned into that electricians nightmare: smoke. So now that we have visual cues of not only smoke pouring from the drive cabinet, but also the HMI giving us the warning that we have suffered a main fuse failure.

So in the AC input side of the cabinet where we connect our cables from the transformer to the unit, there exists the 3 fuses that protect the entire unit from an over current condition. These 3 fuses, one for each phase of incoming AC power, are each rated for 400amps, and they are in seriously bad shape!  These are large sand-filled porcelain fuses, and one is cracked and another seems almost burned!

Now I don't want to get too deep into science and mathematics here, but just know that while we were pulling 400amps on the DC side, the AC side would be seeing no more that around 285amps. So there is no way we blew these fuses on overcurrent, but they are most certainly blown!

Well when the fuses finally cooled down enough for us to pull them the story began to unfold. So this customer would order these fuses from a big name manufacturer of industrial fuses, and then would take the brand new fuse and apply their own adhesive label to it with their internal part number to identify it and then install it into the equipment. Now they did not put any thought into what temperature the device that they are applying said labels to would reach. So as the current flowing through these fuses rose, so did the heat as well. I wish I would've thought to get a temperature reading before they cooled down, but suffice to say the adhesive label began to boil and melt. This created a hotspot in the porcelain of the fuse causing it to crack and begin a cascade of failures that eventually led to the element burning out and ruining our test. 

So because this little sticker was not rated for the temperature of the device it was attached to, it literally caused it to fail even though you would think there's no way a little piece of paper would cause a $400 industrial fuse to fail like that! I was amazed!

Now I know that most of you here are far more mechanically inclined than I so I wouldn't dream of trying to "teach" anyone anything lol! But I just figured I would come tell this story as a reminder to all the tinkerers out there that just because a change might be small and insignificant when compared the overall project, but the butterfly effect can be found in a lot of unlikely places! So here we are, a $1200 failure and a customer witness test that is now in danger of being canceled, all because of 3 little stickers!

So my point is, stay safe, think things through thoroughly, and if it doesn't feel right, well it probably isn't right!

  iEFIS/Standard instrument installation times
Posted by: Casey - 08-01-2019, 09:59 PM - Forum: Instruments - Replies (11)

Hi everyone! So I’m closing in on my solo and then hopefully it will just be a short road left to my full PPL and then it will be time to focus on my build.

But in the meantime when I’m not studying I’m trying to make some difficult decisions, and what I’m stuck on right now is instrumentation!

Okay so I know the topic of whether to use the standard instruments or a full EFIS glass cockpit has been beaten to death and I’m not trying to open up that particular can of worms.

But my entire build is going to be viewed through the prism of my build time unfortunately. With a full time job and 3 weeks of vacation which I could probably get away with taking an extra week of unpaid time off before they want to just get rid of me lol, every decision I’m making is gonna be related to how it affects the overall build time.

I really like the idea of the EFIS panel, and I’m willing to spend the extra money on it, but my question is how much time, realistically, the installation would add to my build. 

And yes I know that build times are almost exclusively reliant on build skills, now I’m not gifted like my brother in small piston engines, but working in the controls and automation field has left me with a modest skill set to call upon. So just assume average skills for comparison, but I’d be very much interested to hear about your installation times!

I was also curious if anyone has moved over to the MGL Explorer or Discover iEFIS’s yet? The touch panels sound amazing but it seems like any iEFIS that I’ve seen in a Mosi has been the older model Enigma panel, will the install process be the same? Or is it like my Variable Frequency Drives, every new model comes with different termination points and installation quirks lol!

Anyways any help y’all could toss my way to better assist my decision would be greatly appreciated! Yeah I know at the end of the day the Mosi is more like a motorcycle, just hop in and putt around town for a little while and come home, no need for fancy electronics! But the way I figure it is, I’d rather have every little possible thing available at my fingertips and not ever need it, than to get into a situation where I need it but don’t have it.

P.S. Jeez I write some long posts about simple questions...I bet y’all who met me at the fly-in we’re glad I’m not like this in person!  Tongue

  Hello from France
Posted by: William Le Ferrand - 07-26-2019, 06:57 PM - Forum: General Discussion - Replies (8)

Good morning everyone, 

I just picked up my kit and I can't find the words to describe how excited I am. I'm coming from the certified world, I restored / flew a piper aztec for a while and just recently started to fly helicopters. 

Looking forward to turning that pile of parts into a wonderful flying machine!
