RC Helicopter flying, RC Cars and RC boating

Made for other people and me to track what I am doing when with my remote controlled units. It started out with helicopters. Hence the name.

If only one of my units is of interest, this unit can be clicked on the right and only posts regarding that unit shows up.

This blog is open for comments so feel free to leave a comment.

Added Xtreme production heat sink

walkera 4#3 Posted on Feb 23, 2008 22:09:43

Today I added the Xtreme production heat sink to the main motor of the Walkera 4#3. It was a little loose so I bent it a little to make it fit tightly smiley

It seems there is always a problem with this little bird smiley Today I encountered several:
1: Battery tray broken – fixed with soldering iron
2: A main wing was tightened
3: A flybar paddle flew off during flight – Was recovered and put back on
Maybe the main motor is also due for replacement?

Anyway it really flew excellent after the main wing was tightened smiley

Walkera 4#3 airborn again :-)

Yesterday I got my new batteries and battery holder for my walkera transmitter. I just had to charge the batteries and solder a JST connector onto the battery holder then the transmitter worked again smiley
The back cover og the Tx won’t close now. I don’t consider that a serious problem though.

I was a bit concerned if I could still fly this little bird but that went fine. I don’t think I am a where I was when I broke the rotor head but I wasn’t too bad a pilot smiley

I am also considering how to save weight on the Lama without making it look stupid. A brushless upgrade woud save a lot of weight but is also very expensive so this will be the last thing I do.

Walkera 4#3 repaired – batteries exploded!

Last night I repaired my walkera 4#3. This time I didn’t destroy any parts good in the process smiley It looks fine and seems to be working. The transmitter was low on battery so I didn’t get to fly smiley
Today I found out that the E-sky charger power supply fits right into the walkera charging jack and almost all seemed right. So I plugged it in and started charging. Some time later I heard a bang and I saw smoke from the transmitter. I quickly disconnected the power supply and opened the Tx. Here I saw meting plastic and batteries not looking good smiley
The batteries were placed in my kitchen sink as they were very warm and now I am looking for new batteries and a new battery holder. It seems that the Tx is still working.

To sum up: Do NOT charge your Walkera TX with your E-sky charger power supply!

Now I broke another rotor head :(

I replaced the walkera 4#3 main motor last night and it made the bird fly again smiley
Actually it flew so good that I tried flying around and then I hit an obstacle smiley and broke the rotor head smiley This is bad because I don’t have a replacement part and I don’t expect one to arrive before christmas and maybe not even before newyear. So there probably won’t be any more flying of the 4#3 this year smiley

Another worn out motor

walkera 4#3 Posted on Dec 19, 2007 17:27:59

It seems that the main motor on my Walkera 4#3 just doesn’t last long smiley Yesterday I experienced very short flight time again. This is exactly the same symptom as last time I had worn a motor out. So I will be replacing the motor tonight.

Anyway I think I am getting better at flying this little bird. I feel quite confident flying without the training gear smiley I am also beginning to try out some new flying that isn’t just taking off from the floor and make spot landing on my tables smiley

Broke the rotor head

walkera 4#3 Posted on Dec 02, 2007 21:29:18

Now it finally also happened to me. I broke the rotor head on my walkera 4#3 smiley
I had a spare so I have repaced it. It isn’t very easy to remove main gear from the shaft, so I broke some parts to get the main gear off and the process was quite difficult. I did however succeed and this little bird is flying again smiley
I checked miracle for a spare rotorhead. They were however sold out. I guess I will have to check until they get some more so I can have a spare one.

Now flying the 4#3 without training gear

walkera 4#3 Posted on Dec 01, 2007 16:51:26

Now I have had the walkera 4#3 for some months and today I felt confident and removed the training gear. I discovered that I can fly this little bird without the gear smiley Very unlike last time I tried. I also ordered some spare parts today to be sure I have them at christmas. It seems that replacing the main motor will be a recurring activity and it woud be too bad not having a motor at christmas.
The landing gear is very slippery so I think I will have to find out something to increase friction on the landing gear so the heli won’t spin 360 degrees at landings smiley

The motor was the problem

walkera 4#3 Posted on Nov 26, 2007 21:28:08

In the weekend I tried flying the 4#3 with batteries known to be OK and it only flew for a few seconds, so I concluded that the main motor was the problem. I couldn’t repace the motor in the weekend so I tried today and it prooved to be the main motor.
After having replaced the motor the 4#3 flies very well again smiley
I also received some new spare parts for it today. Two extra batteries and some misc. spares.
Now I am just wondering how many spare motors I should order smiley
