Hi guys its done at last but one job of the fitting the castle esc has now been done
The set up was easy ,I did do the fixed points set up I thought that was going to be hard but was really easy , I didnt set up auto rotation as I dont feel I will used it , Feels strange to only have zero throttle on hold ,I just need the weather to change so I can go fly, so the finished spec is
Trex 500 pro dfc converted to the trex cobra
Hyperion 1000kv motor ( thank you Troy)
Castle talon 90 amp esc

Its nearly done navigation lights in changed LEDs from the 5mm down to 3mm , this has a more scale size , Thanks to Troy I fitted the hyperion 1000kv motor , with a 17t pinion and a 162 main gear from the older trex 500, this gives me a nice head speed of 2070 at full so once the castle ESC is in I can govern down to 1900 , The tail wag was a mix of mechanical set up and Kbar tuning ,so I re set the tail and adjusted the Kbar by lowering the I gain and raising the P gain and stop gains
In the test I didnt have the spin blades on the head as they had not come , I fitted the 75mm spin tail blades ,as the head speed was coming down I wanted to make sure the tail would hold , Here she is on a fixed throttle of 80% till I have a governor esc in place
Align trex 500 cobra wag fixed (5 min 42 sec)

Hi guys this is an update on the cobra , To start off I want to thank Steve aka jetplaneflyer for the kbar gyro , and a big thanks to Troy aka Heli -Heaven for the 1000kv motor he has posted to me , thanks guys your both top guys , also to Viktor as he always makes me Laugh , and while I am doing thanks , there are 2 scale guys that are a great help to me and thats Don aka keyrigger( heli whisperer to me ) and justy g Thanks for letting me pick your brains your top guys
Ok to the cobra I am waiting for parts i have a set of Navigation light as these come with 5mm leds I got some 3mm leds as they are a better scale size for the Cobra.
As for sorting head speed this will be done by fitting a 1000kv motor and putting in the old trex 500 main gear with a 17t pinion, this will give me 2070 rpm
I will then govern this down to 1900 and if i am right that should be between 75-85% throttle , I am hoping this will either give me more flight time or stay the same I will be happy as long as it does not go down , The mcfarlane pilots are still not here , getting worried now I hope that was not 92 loss , I emailed the guy so will give it till next week , if still not here then I will get on to e bay
UPDATE they came wow time to cut them up
Kbar is super stable (5 min 44 sec)

Hi guys the pitch is now set up i had to up the point 3,4 and 5 ,It takes off nice now
The wag on governor mode is back ,so its now turned off for good ,I will be getting a new ESC and 1200KV motor so i can lower head speed more but its much better now
turned off governor mode on ESC (1 min 17 sec)

Posted by holtneil | Jan 04, 2015 @ 07:57 AM | 6,115 Views
Well i need gov mode , I know the Kbar has it but just cant get my head round how to set up ,When i strip it down again to fit navigation lights i will have a go at set up , If i cant get it to work i will buy a 100amp YEP that has gov mode
So for now I set up normal flight mode for take off , then hit idle 2 and this has a flat 85% throttle so the hover is a bit better now
trex 500 Cobra,constant head speed need gov mode (5 min 27 sec)

Hi Guys well another test flight I gain on tail down to 40% great news wag has gone .
Weapons pods made up and fitted , i drilled a small hole in the side of cobra where the weapons pods mount ready for Navigation later on once i found the right ones ,I do like the ones RC aerodyne do ,so mounted pods on body , now test flight went ok will start to fit the heli in , Still waiting for the mcfarlane pilots to come , they must be walking here not flying

Hi guys well it was test day and first video heli has the wrong throttle curve heli its hard to fly , it also had a killer wag , But again Thanks to Steve aka Jetplaneflyer ,he said reduce I gain on tail and as you can see on second video its almost gone , and the throttle curve has be put to the align one of 0,40.75,85,100% on an 11t pinion stock main gear, and heli is so much nicer

Well guys at last its ready for a test flight , the battery is just hanging on to balance the tail, i had to brace the tail to make it stable ,once its in the body it will be supported , and a BIG Thanks the Steve aka jetplaneflyer, for sending me the kbar blue koala to get me flying again after the 3GX failed , its never been right from day one , thats it now will never use one again , so will up date tomorrow but here are some pics
Posted by holtneil | Dec 29, 2014 @ 02:48 PM | 5,047 Views
Well i knew this was going to be fun , I spoke to my mate Raj who own align.co.uk as i got the Cobra from him he is going to get replacement parts from Align.
Well the heli is built be due to the 3GX playing up i cant trust it any more , but lucky me there is a top guy on RC groups goes by the name of Jetplaneflyer and what a guy he is ,he is putting a Kbar blue koala in the post to me so i can get flying Thank you so much
Parts for the Cobra will be about 6 weeks but i can carry on with build
I hope the 2 mcfarlane pilots come soon so i can mod them to fit

Hi guys well its Christmas and my Align cobra has come , Well I am not that impressed , Align Helicopters are very well made but the Cobra which was not cheap at 300 is rough in places , the main guns were just thrown in the box and they are bent and the paint has fallen off one and front support is broken , Then second problem is the inside cockpit is out of shape , So i have my work cut out making new guns and heating the cockpit back in to shape
I will try and do some photos of the damage and post on this blog

Hi Guys , well let me say from the off i dont want to be hung,drawn and quartered, with my remains thrown the a pack of hungry dogs lol This is NOT a scale build ,i just wanted to look at a heli not pod and boom
The KDS Jet Ranger is not a really expensive kit so i didnt expect a lot from it , my big problem is i dont have a KDS heli to fit in it ,so i had to do a lot of trial and error fitting and testing .
Problem 1, was the tail servo on the black angel i am using is massive and you cant get heli in body with servo on , so i had to mount servo direct to heli , i used the gyro mounting plate to fit servo too.
Problem 2 , now the servo rod is too short , so had to make rod longer i used a small wire clamp stripped down and joined two rods .
Problem 3,now with heli in body the servo rod hits where the body becomes tail ,so i shaped the rod to miss body shell, and use a loose zip tie to hold rod up .
Ok so now every thing works and servo is not hitting the side , but i have lost servo travel one side , so take it all out again and use PC to adjust end points and travel on gyro.
Ok before i refit put in scale lights , now wire up and refit heli , i had to use larger screws due to the the ones the kit came with will not go through skids and into wooden frame .
Next problem skids are not true so i had to fit a spacer under one corner to get heli to sit on all fours .
the next job is to fit tail fin , its says drill 4 small holes in tail to screw the tail fin on ,

Hi guys well as the airwolf is on hold ,i managed to get my hands on a KDS Jet ranger , so the fun starts due to me not having a KDS heli i having to mod things to get the black angel in , so watch this space for a build log , oh well back to trying to get tail servo in body as it does not want to fit...... , WHATS NEW lol
Posted by holtneil | Aug 22, 2014 @ 07:05 AM | 5,361 Views
Hi guys , well 500 pro is great i had to re-flash 3GX from v5 back to 3.2 , due to tail wag or tail kick , but 3.2 flys well, now looking into a cobra AH-1 body heliartist one comes with aircrew the align one is just body , do i want to spend 100 more for aircrew with the heliartist , if i can get it over here then yes its look so much more scale
The airwolf has been set back due to the black angel not fitting in , so if your getting one your need a pro air frame the angel is to tall and the tail servo stops the heli from fitting in the body , not happy as it says in the copterx site it fits , just glad i didnt buy second angel to fit in this body , so its on hold for now , want to get trex dressed up first as it flys so nice
keep well happy flying
Here are some photos of the trex and i tried to keep install clean i hate wires every where
UPDATE ON UPDATE
well the heliartist AH-1 will not fit the new 500 pro , so i will have to go with the align cobra , there is a add on fitting kit due to the new 500 pro having the wrong type of bottom plate ,battery plate and some other parts just glad they do a...Continue Reading
