Well, after a good 6 months on WordPress.com I have decided to move the blog to my own hosted site so I can add a few plug-ins and have a mess around.  

The blog will be the same one written by me so get over there now by clicking the link http://helikid.com

See you there!

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.

Align FL760 3G Settings

I have just brought the 3G link cable so I can update the T-Rex 250’s 3G unit and tweak the settings to make it fly better.

As part of the software you can tweak each of the 22 settings and each one can have an impact on the 3G unit’s behaviour. Therefore so I can sit on the sofa read about it better I have screen shotted the lot.

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.

Mini Titan starts Car

Went up to the new club that I joined for a fly yesterday and the weather was pretty good, a bit windy but nothing to harsh to stop me flying. (Unlike today maybe) Anyway wanted to share an amusing story – having not taken my leisure battery up for battery charging I decided to use my car battery to charge up a couple of the Protos packs as I wanted to fly some more.

Brilliant idea until the charger warned me of “input volt err”, so hoping and behaving in true British fashion I thought the car would still start. It didn’t. Fortunately I carry jump leads in the car so I had a backup plan but not wanting to look like a idiot came up with an idea. My charger can charge lead-acid batteries so by connecting the charger up “backwards” and using my Mini-Titan (11.1v 2200mAh) batteries I charged my car battery up 🙂

So two top rules:

1) Don’t use your car battery to charge your heli batteries.
2) If you ignore 1 then make sure your charger can charge lead acid batteries.

Give me power!

Got home today after an evening fly to find the postman had delivered the batteries I had ordered from HobbyKing (click here).

Turnigy Nano-Tech 6S 5000mAh

Turnigy Nano-Tech 6S 5000mAh

When I brought the T-Rex 550E I also got 2x Align 4600mAh packs. Ideally I think you need 4 packs (4 flights) or it is a pain when at the field. You can normally charge a pack then and keep flying. Therefore I thought I should try the 6S 5000mAh Turnigy Nano-Tech’s. They seem to work well on the Protos so why not.

They come with 10 gauge wire so I should be able to get them into the EC3 connectors that I use.  I should have them working by this weekend so I will update the blog with my first impressions then.

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.

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.
