Pictorial Build Diary

[CaLviNx]

Hi All

I have done a pictorial build of my Trex that might just help a few people out with some points, im in the middle of putting the diary online on my webpage so as soon as it up i will post it too

Diary

Hi

pictures for build diary uploaded well most of them i ran outta disk quota so no space left.

Im thinking of putting all the pic on a dedictated webpage anyway, so I will host them somewhere else and link to them here. more of the pics are in my gallery




Regards

Looks cool, nice pics, very detailed

Can't wait to hear how it flies, I'm almost at purchase point after researching them on the web too and an Maxi Joker 2 perhaps

Increased gallery to 10000kb, temporarily I'll re-size your images. 800 x 600 will give a good resolution and picture quality.....

All Uploaded

Thanks for the increase.

I have just finished uploading and have added some text to the pics to help with explaining some of the build for those that need it.

I have also added a pic with eCCPM conversion kit i have just obtained from a fellow flyer in Austrialia. I will be flying my T-Rex (when this effing wind dies down or i go to the local school gym) and testing the heli out in standard form then fitting the eCCPM to obtain a comparison.

Check out the pic below and follow the link for more info on this upgrade.

I've ordered my TREX 450X and can't wait for the postman to bring me much pleasure

How's yours going Calvinx?

i can think of better things for pleasure than a heli......and you can get them mail order..

Theres always one...

Theres always one... depraved twit "or should that be twat?" who is not getting enough so they feel the need to vent their desires in the forums............

mind you from not getting enough will lead to extreme ham shanking will make him blind enough to not be able to read this insult.......

lets keep it focused on the topic at hand children.

My rex went of a major diet due to crap weather and it was just sitting there looking at me like they do...weight reduction for no other reason than I can and its supposed to make for longer flight times. So hey why not I like to tinker/engineer as much as fly.

So it has had major frame liposuction via Mr Dremel and a part commercial eCCPM kit part home brew effort (the bought eCCPM kit had unequal length linkages that I didnt like so I modded one servo position to have them all the same length), that just needs the final setting up of the radio, canopy painting and some decent weather, or a trip up to the farm into the potatoe shed for some indoor flying if I get that fed up with the weather. Or go to the local school for a heated indoor flyin that im hearing is supposed to be coming off in our local arera

I will post some pics of the eCCPM mod as soon as I can be bothered to dig out the digital camera.

Hey Calvin

Great Info in the build diary many thanks

I notice you monitor and post on another forum quite frequently and they all mention how there is loads of slop in the controls.

Have you found that if you are careful during the build that you can actualy get rid of most of this slop without resorting to buying a shed load of upgrade parts as the Yanks seem to like doing and shouting bling bling at the same time?

Very interested in hearing how your flight comparisons between Mechanical and eCCPM work out.

What made you decide to go with the 3DE CCPM kit as opposed to cutting the frame and mounting the servos directly under the swash.
I have seen a few conversions where this is ver neat with equal length push rods and servos acting directly on the swash?

I am interested to hear your views.

Many thanks

Slop Removal

Hi

I try to build with as little user related slop anyway to I tend to look for slop and try and remove it when im building be it by carefull assembly or I will resort to raiding my spares box to find somthing suitable or end up making it.

I know im gonna get flamed here , but 90% of what the yanks are doing to add "bling" is for that reason alone, but thats the yanks for you and if it keeps them happy then leave em too it.

if you look at the very messy pics of the eCCPM conversion I have bought then modified, you will see how that the frame has been cut at the front and from my efforts at frame lightening I used a G10 plate to locate the rear servo with inbuilt spacers in an attempt to get the linkages vertical as poss. And all three servos are on the same level, so using my linkage tool it was very easy to get all inkages the exact same length. we will see how it flys.

Some of the other kits that locate the servos at the front vertically,they look good and as this heli is for modifing engineering wise as much as flying. I might change the front servo locations yet too after test flying this setup just to get a comparison as G10 and cyano are cheap and easy to work with.

I think the only reason I can see to slot the front servos in vertically is to get a better linkage angle, which might remove any possability of interaction, im now in the middle of making my own alloy tail pitch linkage with bearings instead of a brass bush as this is a area of slop I couldnt build out.

As for the flight comparison in standard trim I did three flights and though it was comparable to a 30 size nitro machine running on really crap servos.

It was how shall we say very "responsive" in cyclic to say the least and tended to want to wander off on its own like a forgetfull puppy.

[wazzer]

Are you Doug by the way?

So in standard fair you say it flys like a 30 on crap servos.
out of interest can you tell me which servos you are using i cant tell from the pics?

do you think you will bother to remove any of that excess G10 from the front now that you have relocated the servo

You may save a bit more weight!!

Thanks for the info

Hi

No im not Doug my name is Mark.

Im using BlueBird 371 servo's (13.00 each) with a high torque rating.

I think the only portion of G10 I will remove now will be the vacant front vertical servo bay. With Canopy on all up weight is just under 500g on the wifes kitchen (non digital) scales so im happy with that.

I have a carbon tailboom to go on and I have a length of carbon fibre rod that I might try out making a hollow mainshaft like has been bandied about on runryder.

Im in the middle of making a Mini DIY 4 axis CNC mill using a cheap router as the motor, so once thats finished I will have a bash at making some parts out of aliminium like washout and such like.

how do you post pictures in with your posts,ive tried working it out but i cannot figure out whats going wrong?

How to post pics

Hi its easy when you know how really

I use a photo repository online to hold the photo for me

www.photobucket.com register there and follow the onscreen prompts on how to uplaod a photo to your allocated space on photobucket

then when you want to post it in here for example you will get an "image listing of the photo"

it should look somthing like this listed below without the brackets but at the front of the image code you will have the code "[IMG]" & at the end "[/IMG]"

"http://img.photobucket.com/albums/v607/CaLviNx/eCCPMConversion001.jpg"

And i have insterted a pic of similarl code to let you see it.




if you use photobucket it automatically has the image tag codes on the line for you then you then just paste that whole code into your message body when typing and post it, thats all there is to it.

It is actually harder to explain than bloody well do....

i will try it as i already have the photobucket hosting site.
