My General thoughts and musings
By Nigel on Saturday, 25 July 2009 10:45 AM
Wasn't too bad a morning for flying.  The winds were there, but not as strong as the weekend before.

I did the usual hovering, just to get a "feel for the day" and the winds.  Im still lacking a bit of confidence nose and left side in, which is annoying.  But still did some anyway.  plus the usual "mandatory" piros LOL

Now the "new manoeuvre" LOL...  I started doing some circuits.  Just simple left to right, turn, right to left, turn etc.  I have been practicing this on Phoenix, but...

A nice flight for the mini titan.  I discovered that the top collar on the main shaft came loose, so before the flight I tightened this up.  This might have accounted for the blades not staying in track.

Im still not happy with the esc on the MT.  Wether I have it configured for governor mode and this is the reason for the higher head speed when pitch pumping.

I had to adjust the blade tracking again, but once adjusted, it stayed spot on for the rest of the flight.

Flight consisted...

This was a test flight to see how the new wooden blades are that I bought from Take-Off and Land.  Half the price of the Thunder tiger blades.  From this (short) flight, they seem pretty good.

The flight was just hovering around in the back yard.

It only took 1 turn on the slave short link and 1 turn on the slave long link to bring the tracking almost into alignment.  I might be able to get it closer, but it is les than 1/2 blade width out.

What was interesting was that this battery at the end of this flight has 7 (nearly 8) minutes of flight on it, and its only taken 1026ma (in 66:01 minutes) to charge.

Not a good flight with the little mini titan.  The turbulence was terrible and when trying a piro, the wind took it close to the kids swing set, so it was ground it quick with some damage or hit the swing set and posibley greater damage.

Unfortunately I hit the wrong switch (flight mode and not throttle hold) so ended up doing a main gear as well as main shaft and the usual blades.  Im glad the blades were only woodies.

I didn't charge the battery.  The flight was just short of 4 minutes

Wasn't too bad a morning at SARCH.  Until you got out of the car and felt the icy chill of the winds. LOL

I had two flights.  7 and 12 minutes

First flight was nothing special, just the usual, tail, left and right side in hovers with some full and half piros.

The second flight of the day I did the bronze wings test.  It comprised the following manouvres:

Take off and hover at eye level (above the pad), then land Take off to eye level, then move away from you...

I wanted to get another flight in today, but the winds were a little too blustery.  Thankfully they settled down a bit so I went for a flight.

I am a bit worried by the motor's behaviour, but i suspect it is more the esc than the motor.  When I spool up then flick to idle1 the motor is fine.  If I do a pitch pump, or give a quick burst of cyclic the head speeds up (as per the throttle v-curve), but then it wont slow down unless you just about spool down.  I might try re-programming the esc...

It was an interesting flight with the Mini-titan.  About a minute into the flight the heli lost power like the low voltage cut out had kicked in.  I spooled down, then back up and all was fine.

The tail is holding well, a lot better than the JR410 ever did and the piro speed is ok.  I will have to reduce the expo on the cyclic as I found I was having to put a lot of stick input in to correct and move around. :)

Battery #4 took 1527 ma for a 7 minute flight and 82:34 minutes to charge

I managed 3 great flights with the trex600n today.  They were 7, 8 and 6 minutes each.

I had trouble with the heli not wanting to stay running.  I suspected that the glow plug might be the issue as I couldn't remember when I last changed it.  After replacing the plug, the heli started easily and didn't die when the glow igniter turned off, so definately plug replacement time.  Upon inspection of the old plug, the first 3 coils were not glowing.

The first fligt I spooled up took off to about a 2metre high hover and the heli was just sitting there so I took my hands off the sticks.  Other than the breeze blowing the heli to the left slightly and having to correct it, I could have hovered for a lot longer with no hands LOL.  It was only about a 15second hands off hover, but its a nice feeling as to me it means that the heli is pretty well trimmed. :)

Another test flight out in the front yard..

I leaned off the mixture screw a couple of clicks. Then tigthened up the mixture control lever.

It was a lot better, the temp did manage to get over 80c (max 86c)  I was also able to see the mixture servo start to richen up the mixture and as soon as it started to do that the engine started to bog down again.

Unfortunately the winds started to get too blustery so i landed and shut it all down.

Another 6 minute flight.

Not very nice weather again for flying, but i still managed 2 flights (6 and 3 minutes)

The heli with the mixture control installed is running very rich, even after leaning off the needle a couple of clicks it was better, but still very rich with the mixture servo staying in the full lean position.

I just did basic hovering with more right side in (so i could see the mixture servo)  Also did some piros.

The second flight again much the same, but cut short by the rain.   It wasn't...
