Looks like fun!! Glad he's changing the tires though. The ones on there don't do it justice.
You thought climbing in and out of the moterhome was tough on your legs! A few times climbing in and out of Jay's new toy may require some new joints in your knees.

Please be careful when you do this. A moth is officially considered an insect!!

Hmm.....nobody around since last night?

Had a ho-hum flight with my Moth this evening, to see if the vent "system" is working. When I went back to flying the Moth with the cowl on it, the heat sink would get rather hot. So, I cut vents in the cowl, hopefully to get an extraction effect. Also cut out some foam from the "battery department" to promote further venting of hot air. It appeared to work a couple of weeks ago. Thought I would try it again and check for temperature. Seems like the "system" is working fine. Relatively a short flight, 19 min 15 seconds, to an altitude of 497 feet. Ambient temperature was 76. The heat sink was barely warm. Think I will stay with this arrangement. 9x7 SF prop, stock IPS "A" power system, TP 1320 2S1P blue stripe LiPo. Rather pedestrian but effective. Still thinking about trying that Feiago on the shelf. Just need an appropriate brushless ESC.

Just reporting here that the replaced rudder servo did the trick!! Thanks for the help folks. The rudder centers true every time now, no hunting or false centering.

Do servos fail like this often? All of my servos are GW or Hitec and the oldest are 14 months or so.

When they do it is usually caused by stress on the servo from a crash, moving the arm manually or forgetting to turn on the TX first and servos go past full deflection.

Boomer, that explaines it. Tho i haven't smacked my TM up, I did use those servos last winter in a plane that had a rough life!! They were in a foamfly frog that got it's tail section ripped off by a mean set of power lines.


Waiting to hear what you think about the Shinden.

nah, I have picos and naros that are 3+ years old. It is all in how bad they get abused. I thought that s75 servos were pretty bad as I had a set of them fail, supposedly they were just from the first batch released. However I have a set of 4 now on one plane with no problems. Sometimes you just get a bad one as well.

Speaking of s75's. I saw this 4 pack for $20 and thought they would work in my coming TM 3d. Seems outrageously cheap (inexpensive). Are there cheap knockoff POS's floating around the internet or are they all made by the same company? I've also seen some planes using stronger servos for some controls and weaker on others. Is there a general rule for this?

I've emailed them asking about availability. for that price i'll give them a try. Every one I've looked at on the net looks exactly the same with the same accessories. Only diff is they're $14 each!

I've also seen dx6 radios advertised without servos. Maybe that's where they come from???

Just want to be sure I have the correct heat sinc. The package says "EHS-12" on it. It is a VERY tight fit on the motor and is a tiny bit too long for the gearbox opening (I slid the motor out, but the heat sinc would not quite slide into the "gap".)

thanks,
Eric

Eric I had the same problem, and I never found a fix, I guess I could have used a dremel to take some meat off of the heat sink, but that defeats the purpose. I chose in the long run not to use it. I would be interested in hearing a fix for that as well. I would still like to use a sink on my Feigao 12mm motor inside the IPS box.

File or grind off to fit and be sure and use heat paste when you put it on! Heat paste is available from Radio Shack.

or do what I do...small piece of sandpaper to the rear and forward area of the GB it's usually about 1/2 mm or less on either side; and plastic is easier to sand than metal is to file
