A blog on my TRex 600 Nitro Helicopter
By Nigel on Saturday, 8 January 2011 10:30 AM
Weather wasnt the best - warm and muggy, but the storm clouds looked awesome :)

A couple of excellent flights.  My flips and rolls are improving where more and more of them are consistent and "tight"

A couple of the fly-bys that I did with barrel rolls left and right I nailed, with the heli looking like it was on a wire and spinning around this wire.

The second flight I did some inverted nose in hovering, holding it for quite a while.  I even did a piroette whist inverted :)

Beautiful day for flying, although it started to warm up and get a little uncomfortable (heat wise) later in the morning

No new moves, but rather just practicing existing.

Lots of slow piros, piro stall turns, flips, rolls and loops.  A very small amount of inverted hover (hold at top of loops)

I feel that my flips and rolls are improving, getting more consistent due to better pitch control

I can never work out why the first flight always uses more fuel than subsequent...

For the first day of the year the weather started off not too bad, but then the wind whipped up a bit.  Still ok, but was a southerly which I don't enjoy as much as when from the nothern sides.

Despite the wind, I still had two good flights.  The rolls were a lot better than they have been as were the flips.

Some inverted hovering - loop, hold inverted for 5-10 seconds, then complete the loop.

Flight times of 10 and 11 minutes, with engine temps of 93 and 103

Beautiful conditions for flying.  Humid and slightly warm with no wind.

Nothing new with this flight, just loops, flips, rolls piros etc.

Small amount of inverted (10sec)

Very enjoyable flight

Flight was 10 minutes. Max engine temp was 106c

Merry Christmas!

The weather started off crap, but improved as the morning progressed.  The wind was still annoying and gusty, but at least it was flyable

I made some changes the the 3G software setup last night after performing the "silcone mod" to the sensor a few weeks back.

I was not prepared for the dramatic changes in the heli's behaviour.  It has gone from an OK flying heli to an awesome flying heli :)  It felit like it was on rails.  It would do as I told it and do it very well.

I also...

During the week I leaned the main needle off so it was 1.5 turns out.  This seemed to work well for the first flight, but given the ambient temp (and the bogging when doing flips etc), I decided to richen the mixture up for the second flight to 1.75 turns out.

both flights consisted of flips, loops, circuits, rolls, piro stall turns and some inverted hovering.

Second flight I also just had a bit of fun "freestyling it" zooming around the sky

Engine temps were 104 and 109 for...

Well the weather wasn't the best for a flight, but I managed to find a gap in the weather to have a flight.  The winds were quite strong, but strangely only noticible when performing loops, flips and rolls.

This was also the first proper flight since I performed the silicon mod to the 3G sensor.

The heli is more twitchy at light skids, but seems very locked in once in the air.  My flips and rolls were a lot better than they have and the heli felt as though it was doing everything i was telling it to.

By Nigel on Friday, 19 November 2010 5:52 PM
Just a quick flight to see if i could notice any difference after doing the "silicon mod" on the 3g sensor which involves putting a blob of silicon on the sensors to "link" them all together in an effort to try and reduce vibration and oscillations.

The heli did seem a bit more stable whilst hovering about 1-2 metres off the ground.  I will have to wait and see when I go down to the field next weekend

I will probably need to lean off the mixture by a could of clicks as it is still running...

The flight went very well.  The Hatori pipe makes nice power and  doesn't bog as easily.  Given the 9 minutes of flight time, I think it is still running way too rich (and the max engine temp confirms this).

I performed my first (and second and third) inverted hover today.  They weren't very long (30seconds tops), but I completed them no probs :)

The flight lasted 9 minutes and max engine temp was 71c

Test flight after cleaning the carb out a bit and also winding out the needle by 1 turn (richening it up)

Just hovering around the front yard.

Flight times were 5 and 6 minutes, with engine temps of 59 and 79

Beautiful conditions for flying.

I have installed a new pipe - Hatori 522, to fix the rattle in the old align pipe.  At this stage, I don't know if it has improved anything, as the engine has decided to run lean (as indicated by the engine temps

I still had a couple of nice flights though with loops, rolls and flips etc

The short 2 minute flight was annoying.  I decided to quit as the heli would idle beautifully, but would flame outwithin a minute or so of spooling up.

By Nigel on Saturday, 23 October 2010 10:00 AM
These were the first decent flights after the engine rebuild.

The first flight I took it easy.  I still did some flips and loops, but most of the flight was just doing circuits.

Second flight I stepped it up a little.  More flips, a couple of rolls and of course loops and stall turns.

The engine is definately quieter, but now I hear the rattle noise in the muffler LOL.  Also feels like it has a bit more power.  I think fuel economy has improved slightly as well.  Back to what...

Just a quick flight to check the motor after the rebuild (new ring and bearings)

Motor went well, started first pop into a nice idle.

The flight was just hovering about 1/2 to 1m off the ground

Unfortunately the flight was cut short (still had a small amount of fuel in the tank to use) as the plug had decided to die on me.  The engine would run fine with the glow starter but once that turned off, the engine would stall.

Max engine temp was 69 for the flight.of about 5...

Beautiful weather for flying today.  Best weather we have had for a while.

Both flights consisted of flips, loops, rolls, stall turns and piro stall turns.

Very enjoyable flights.  My back flips were very good, with me stringing together probably 10+ (I wasn't counting so im not really sure)  My forward flips weren't too bad, but were a bit wonky at times.

Rolls as usual need lots of practice, but im able to string a few together when flipping to the right. 

Each flight...

This was sort of a show off flight down at the ex-wifes place to her fiance (also interested in RC).  Nothing special about it.  A few flips, loops and rolls and forward flight.

I did lean off the needle slightly, but will need a better flight to determine if the needle setting has helped or not.

Flight time was 9 minutes, max engine temp was 111

By Nigel on Monday, 4 October 2010 10:32 AM
Weather was the nicest it had been for the whole weekend.  The clouds were thinning, but unfortunately the winds also started to pick up a bit.

Two very enjoyable flights.

Both flights consisted of the same moves (flips, rolls, loops, stall turns, piro stall turns etc)

I did do the left/right roll combination in FF that is required for gold wings.  Not very tidy, but i did do it. :)  I also strung together half a dozen or so continuous back flips.  I only stopped as the heli was drifting to the left.  My forward flips were terrible as I kept giving slight rudder input causing them to go off all wonky.  Did make for some rather interesting exits from the flips testing my "orientation awareness"

By Nigel on Saturday, 2 October 2010 10:13 AM
The weather was nice apart from the winds.  I decided to only have the one flight, as even though I had a good flight, I didn't enjoy fighting the winds

The winds made it hard to keep the heli close and low.  it was wierd having to fight the heli.  But the guys with the flybarred helis seemed to have to fight even harder.

Still managed to do some loops, flips and rolls.  The piro stall turns were hard.

The flight was 10 minutes and max engine temp was 94c

By Nigel on Saturday, 25 September 2010 9:52 AM
Wasn't too bad of a morning for flying.  It was cool, but not bitterly cold like it has been.

The flights were the usual moves...  Flips, rolls, loops, piros and piro stall turns.

I replaced the glow plug after the first flight after the heli hiccupped.  The element wasn't too bad (will do as an emergency plug) with the first element being slightly black.  Also looked like there was some gunk on the plug.

I also leaned off the main needle by about an hour after the first flight. ...

Was a strange flight this morning.  The winds were coming from the south, which was quite hard to get used to, given that they normally have been from the north.

I was struggling with the wind to perform the moves smoothly, but still managed to do them.  Just loops, rolls, flips and stall turns.

The stall turns were the hardest as the wind was pushing the heli.

I still enjoyed the flight though.

Flight lasted 10 minutes with max engine temp of 84

By Nigel on Sunday, 12 September 2010 10:19 AM

Nothing new with these flights.  Just loops, flips, piros etc.

Flights were 11 and 11 minutes, with engine temps of 101 and 113

(I should have logged the flight details before I really forgot them lol)
