Honeybee King II adventures

jonnic — Sun, 19 Oct 2008 00:12:09 +0000

Just installed the Extreme 43t belt and pulley, It is amazing the difference it makes in tail response, highly recommended to anyone with tail authority problems! but i had to tweak the position of the rudder servo as the modifications causes to much thrust from the tail blades, a minor problem for such a great upgrade.

Spring time

jonnic — Sat, 05 Apr 2008 23:58:19 +0000

Now that the daylight hours are longer and the weather is better (or should be), I hope to start flying again with some new additions to the Heli. First off my new version of Aluminium Skids with full suspension are now permanently fitted and I am also fitting a camera to the under carriage to get some nice shots from ‘up there’.

Li-Po Puffing after christmas storage

jonnic — Sun, 27 Jan 2008 18:01:37 +0000

After opening my Heli case, I found MY TurBORIX 1800mAh battery had slightly puffed up. Maybe I should have stored it at only 50% and not left it fully charged? These Lipo’s are strange things. But this is the second TurBORIX that has puffed up, my other batterys dont have the problem, i might have to rethink about buying another one.

Aluminium Skid Update… Now with suspension

jonnic — Sun, 04 Nov 2007 23:10:34 +0000

The Aluminium skids have been modified so that they now flex if subjected to a bad landing. The aluminium frame is many times stronger then the plastic stock skids and they do not weigh that much more. I can now crash( not that i want to) and the skids will survive and absorb the shock so as not to damage the heli! I have done some heavy landing tests and the video shows the suspension is doing its job.

I have now uploaded a video of the heli hovering with the aluminium skids on.

Tail pitch control failure, more maintenance!

jonnic — Fri, 21 Sep 2007 14:30:38 +0000

I had a problem with the tail pitch control causing the heli to spin due to lack of control of the rudder.

on close inspection I noticed that a metal sleeve that sits in ball bearing race has slipped out. This brass sleeve comes out when the servo link is moved. This caused sloppy rudder control.

I finally fixed this by buying part number EK1-0295. This involved striping down the tail mechanism. the grub screw was the hardest thing to get out as it had threadlocking glue and the cheap allen key I had was chewed up by the grubscrew. so I had to get a decent 1.5mm allen key and I finally got it undone.

The new part was greased and fitted on to the shaft and the grubscrew was retightend and glued with threadlocker.

All I need to do know is go outside and align the rudder servo and it should be as good as new!

Helicopter Storage Case

jonnic — Mon, 13 Aug 2007 13:38:42 +0000

Here are pictures of my new Esky aluminum case.Â It’s a very sturdy case with lockable latches.

Plenty of foam for securing the Heli and accesories.

Aluminium skids

jonnic — Fri, 10 Aug 2007 13:33:10 +0000

here is the aluminium skids. I have yet to fit them and after discuscusion with fellow pilots I am concerened they are too strong as the plastic skids act as a shock absorber. I may modify these so they absorb more energy during a hard landing. Or wait until I am a better flyer!

Idle-up crash

jonnic — Wed, 27 Jun 2007 13:23:49 +0000

After Crashing in idle-up mode because of a servo failure, I was having lots of problems trying to get the Heli back to working order. http://www.heliguy.com/Forum/no-lift-after-heli-crash-please-help-t7009.html

I changed the servo but found that the swashplate was binding when it was tilted. this was causeing a slowdown on the headspeed, and caused it to be very unstable with not much lift. So after discussion with the nice guys at the forum, I decided to strip down the rotor head and check everything, what i found was one offendng part, the rotor head control link as shown below. This was very stiff and it turned out that the pin was bent. All that was needed was to push the pin out and straighten it back.

The heli is now back to working order without any binding and speed slowdown. One good thing from this is that i know how to strip the head down compleatly and identify any problem areas.

Brushless upgrade

jonnic — Mon, 21 May 2007 13:18:51 +0000

I finally decided to fit a 3900KV brushless motor to my King II today. Since fitting it I have found that the heli is much more stable during hovering and the battery lasts longer now . The motor is no longer hot after the flight and I have also noticed that the noise of the motor is significantly less then the Brushed motor. Another benefit is that the heatsink-less motor has given a 3 gram reduction in weight. yipee.

After struggling to fit the Pinion gear to the shaft, I found that the easiest way was to heat the gear with a butane torch and to spray freezer-spary on to the shaft of the motor; so much easier then brute force!

I notice some people fitted the speed control at the back, near the receiver due to the wire not being long enough for placement at the front. I decided that I did not want to do this and so I had to extend the wire from the controller to the receiver. The wires to the motor were routed around the underside of the frame as can be seen from the pictures. This then allowed for the fixing of the speed controller to the front where the old controller sat.

Flew in to a tree!

jonnic — Mon, 30 Apr 2007 13:12:33 +0000

Was flying my king 2 in the local field with the training gear on and decided to take it a bit higher then I have before. The wind caught hold of the heli and it started to drift, thanks to my simulator training i managed to loop back and fly nose-in. But the wind caught it again and started to make the heli drift towards a large oak tree. I tried to increase throttle to clear the tree but the heli went straight in to the very top of the tree, and stayed there.

I had to climb the 30ft tree to re-claim my heli.

So, the damage sustained was a broken main blade, a snapped skid support and the main nylon gear had damaged teeth. total repair cost was Â£30.

in future i am only flying in tree-less fields!

Crash damage

jonnic — Thu, 26 Apr 2007 12:57:12 +0000

I was flying around the garden and managed to fly in to the dustbin, suprisingly the blades survived but the feathering shaft had to be removed as it was bent. The shaft is a pain to get off but once off was just a matter of straighting it in the vice. The king 2 is back in action now; if only the wind would stop, i could get back to practicing. The simulator will have to do for now!
