Turnigy Update

Went flying this Saturday and I have to admit the Protos just wasn’t flying as well as it used to be. It seemed down on power and as I had begun to suspect the batteries are beginning to get tired.

In fact so bad was the the situation with one of them (2450Mah)  that one of the cells was showing 2.76v and wouldn’t charge and I have had to dispose of it.  The other one I had the (2650mAh) charged but one of the cells was left at 4.14v.

This made me think, have they been good value should I buy again?  I have checked Hobbyking for when I brought them and it goes like this:

10th Jan 2010 Turnigy 6S 30C 2450mAh $50.72/£32.46 GBP (inc del)
24th Jan 2010 Turnigy 6S 30C 2650mAh $61.79/£39.55 GBP (inc del)

I fly mostly Saturday and Sundays so based on that assumption since the beginning of Feb there has been 33 weekends (Its now 19th September).  Each Saturday I normally charge and discharge it twice.  Therefore I have had 132 flights per battery.  This works out at:

Turnigy 6S 30C 2450mAh $0.38/£0.24 GBP per flight.
Turnigy 6S 30C 2650mAh $0.46/£0.29 GBP per flight.

I think this is pretty good, especially when you consider I have actually had more flights than this as I have been on holiday an used them 3/4 times a day for 3 or more days.

It is also worth noting that except for the one that the cell died the other battery is fine for learning etc.. I am trying to learn 3D so I give my batteries a pretty tough time. I always discharge to 80% of capacity and then charge at 1C.

If your not as hard as me on the batteries and fly in a sport style then they will probably last a lot longer. Overall though a great value battery that is good value for money and performance.

Out in the field

As I’m off this week I have had a quick fly this afternoon. Put all my batteries through for the Protos and T-Rex 550 and had some great practice with the field all to myself. Flying TodayOn the T-Rex 550 I have had to turn the expo on the rudder channel up to 15% to make it the same as the aileron and elevator channels. I did this as I felt the rudder was being far to sensitive and moving around whilst I was learning my 3D.

One thing I did notice though was that my charger can only output 150W which @ 25v equates to a charge rate of 6A or 1.2c for the 5000mAh batteries I have. Ideally this should be more so when I have more money I will have to look at getting one with more oomph.

Bank Holiday Weekend

Just a quick update today. Been out flying as the weather and the wind has finally calmed down to allow such things. I have been out practising the aileron tic-tocs and I’m getting there. I had a good session on the simulator on Saturday and watched a few videos off the internet on how to do it. This helped but I need to work at it.  Still it’s like when I started learning the elevator tic-tocs and they were a bit random but now there much better.

After today’s flying I need to change the main gear on the 250 after a little crash, and the Mini-Titan has a horrible wobble in the head when in Idle-Up. Strange as I haven’t really flown it so I’m not sure where that has come from.


My squadron: T-Rex 550E, MSH Protos, Mini-Titan, T-Rex 250 3G

My squadron: T-Rex 550E, MSH Protos, Mini-Titan, T-Rex 250 3G

btw I  did go to the BMFA nationals at RAF Barkston Heath on Sunday but the weather was awful and there wasn’t much flying.  I saw some bits and pieces, F3C, pylon racing and some aerobatics but not any jets. It was a bit of a shame but at least I tried.

Saturday stuff

Quick update in this post.  Starting to get several flights under my belt with the 550 and beginning to love it.  I mean really love it.  Very quick, agile but very stable awesome! I suppose the only problem is that if you get it in a mess then things happen very quickly but hey… Did have an interesting moment where the battery connector started rubbing on the main gear on one flight which pretty much ruined it.  I was very lucky that it didn’t cut through it and cause a power loss and certain crash, just had to change the connectors in the field.

Started having more of a go at the aileron tic-tocs again and I think I know what I have to do now.  Was trying it yesterday and it wasn’t really working but after some advice from a friend at the club I know what I have to.  Note: the difference “what to do”.  So hopefully by repeating it very slowly I will train my brain in to how to do it. I can then speed it up to make it look good.

Saturday 17th Flying

Well Saturday dawned a potentially good day but the wind got up quite high and with scattered showers it didn’t live up to it’s promises. Still it was good to get out and have a fly.

Inverted Protos

I had a good friend up on Saturday who has an awesome camera so here are a couple of shots.  At least it proves I can really go upside down!

You will also notice that it is the Protos upside down and regular readers of this blog will also notice that  I was having severe tracking problems with the Protos. I managed to solve this by changing the blades back to SAB’s.  Inverted ProtosI had brought some Align ones which are fine but for some reason they didn’t seem to work so a fellow pilot suggested I try putting SAB’s back on as that’s what the kit is shipped with.  I did this and it was perfect!  Sometime it’s best not to ask…

Tracking. Again.

Virtually new head.  New Align blades and still the tracking is all over the place!

Okay the details. Went flying yesterday to try the new Turnigy Nano-Tech battery (see post further down) out that turned up on Friday.  However despite my post on June 27th declaring “Protos tracking SOLVED!” it clearly isn’t.  When I put it in the air today the blades decided to go out of track at random, to the extent that half a turn means that one blade goes from being ‘below’ to being ‘above’.  This just isn’t right yet I can’t work out why?  After previous events I thought it had been sorted, however it just isn’t. Hmm..

Still here but RainToday

Just thought I would post a quick hello as I haven’t been on here for a while. Tried to go flying on Wednesday night but the weather wasn’t the best.  A bit too blustery which was blowing the Protos all over the sky.  However I did find a good site RainToday.co.uk which shows you in any rain is coming in. Pretty neat and recommended by me.

Hopefully it will be better on Saturday.

Protos Tracking… SOLVED

Well after a mamoth amount of messing around I finally got the Protos working again yesterday.  Here is the run down:

  1. To sort the tracking out I was recommend to get new thrust bearings in the head as it was notchy and they had never been replaced.  I did this and it tracked fine 🙂
  2. At this point the tail wasn’t behaving properly and it took ages to spool up to speed.  I took the tail apart and discovered the belt was twisted inwards.  (Think of a loop and rolling it like a rolling pin not twisting).  This solved the spool up speed but the tail was quivering and then kicking 90 degrees at random.  Very unnerving.
  3. After some poking about in the wires it turns out that the rudder servo link that goes into the gyro cable was loose! Thus sometimes it was working sometimes it wasn’t.  Once I put this back together firmly all was okay! 🙂

All in all a bit of a nightmare but I got there eventually.  It’s now flying fine and I can get back to it now…

Turnigy nano-tech

Turnigy 2650mah

Turnigy 2650mah

Just ordered a new 6s 2650mAh battery for the Protos from HobbyKing (see here) for $51.99 (£35) delivered. The nano-tech series has just been released and claims 25c to 50c it will be interesting to see if what it behaves like.

I currently have 2 Turnigy batteries for the Protos (2450mAh and 2650mAh) and think they are great and good value for money.  They don’t get excessively hot whilst doing 3D and so far have balanced fine.

Will let you know when I get them in 10-14 days time…

Protos Tracking…

Ever since the last crash with the Protos there has been an inability to track the blades.  They just seem to keep going off track.  I have no idea what it is but someone at the club suggested that the thrust washers in the head may be off.  Who knows!? Getting really annoyed at the moment because all I want to do is fly not mess around trying to get it off the ground..
