As I said, tail rotor has to be turned also, you put it on the motor the "wrong" way. Works without a hitch, BW loops, tic tocs, you name it. No tail fin though.

Yes that will work, but fourstringin still has the tail fin installed. If he moves it forward or removes it all would be good, but the way it is now its not going to work very well.

What ever way you look at it, the tail blades has to ALLWAYS push the air to the right,(looking from tail in) and anything in the way is not going to help much, and definitely not the tail fin :-)

It would seem that way but I have the motor wires flipped so the motor runs backwards. I put the blade on backward because the of the concave. So it makes it like it was on the other side. Pushing air with the correct side.

Now as far as pushing air into the fin, eh makes no difference, really think of it as using the air to pull it'sself instead of push itself. Either push air into the fin or have a tiny space to pull air from if its on the other side mounted as stock.

Mainly i have this setup so it cools the motor. Tail hold is great and works quite well.

It's going to take me a couple weeks to get my super light build done but ill do test with and with out the fin and stock position and report back.

Yep report back, would be interesting, When I tried this and held the heli in my hand and felt the air coming off the tail blade with fin and with out , it was obvious to Me it works better with out. In the end i went with twin tail motors. with out the fin. :-)

Yeah who knows where I will end up on the tail situation. I'm on the hunt for the lightest mcpx build i can make match with exceptional performance. Im currently deep into what im going to do for motor and esc. Tryign to get topper to make me a double fet xp3a to run my main motor. Just started a thread if you want to follow along. I wont be updating it much until i get parts in plus i have a bachelor party this weekend.

But it should be an interesting and refreshing post for a seemingly stale forum lately.

Default mCPx Paper Canopy -- First Aftermarket mCPx Hop-Up?

Hey everyone,

I've made a few paper canopies now, and they've all succumbed to the same fate. The canopy post holes tear. Apart from not crashing, how do you guys battle this issue? Reinforce the holes somehow?

Cheers,

Pete

You could try my canopy pin mod: Cut all four posts in 1/2, then re-join with heatshrink. That makes them flexible (will never break at the root).

Plus reinforce the inside of the canopy around the hole with fibregrass tape, then punch a hole.

I'll try the tape thing for sure. I run the AD carbon cage, so I can't cut the pins

I see.

If you have room you can also add some thick double sided tape on the inside, and punch a hole in it. Does give a lot more support

+1 for tape on the inside. Punch hole, then add grommet.

Default Canopy and Fuselage

Long timer lurker and first time poster

The question of a fuselage had been posted on this tread a few times from reading the various forums.

I just happen to have a beta release if anyone is still interested. I've been using basic card stock paper from Staples, spray paint, lacquer to stiff'n her up and that resultant better coat of color ... and box tape as a laminate.

It definately will take a beating and for the price ... well face it, you can afford to dress her up a little bit from time to time. I honestly believe that this also offers a little more support for the tail boom. After shattering a couple of these I was well ready to try something.

I chose this method initially because I wanted to create my own "wet slick" decals for tail numbers and decoration ... and secondly not have to worry about ink bleeding from wet photo finish paper.

Here are a couple photo's on a demo run. Beta version 1.3

Really really close but .. I am still not happy with the finish yet.

Lacquer everything at least two coats when you are finished with color. This helps to stiff'n card stock considerably.

Laminate the outside of the paper (painted side) only. Then add a strip on the opposite side (inside the fuselage) only where the hole break through. Use a punch tool to break the hole from in the inside out. This way you are not actually removing paper but more pushing a hole through. The outside dimple pokes out and acts as a captive nut to the canopy stays and she hangs on really well.

Both the original and the paper canopies found here still have plenty of room to bite on the canopy stays. It says put with very little trouble.

Default Paper Canopy

I am truly impressed with some of the designs that you folks have come up with.

So much that I added one to my bird.

Hi Folks,

I have been working on two canopy designs using CorelDraw11, so they are Vector drawings. I have made a few now and they aren't perfect but they almost are :-)

Because they are vector files it is possible to easily edit them, add detail, designs, and adjust the geometry and size of them.

I don't really know which other applications could open and edit a CorelDraw file. I have tried in the saving CorelDraw files in other formats like Adobe Illustrator or Autocad format files or exporting them....but haven't had much luck with it.

Corel Draw is a great package but it is a bit retarded in places...Alwayse has been

If anybody is interested I can probably post the files somehow but I am not sure how to do that exactly.

Standby for some pictures of my efforts...Probably......They are a little sketchy and not the PRO results that come together sweetly in my mind's-eye :-)

I am quite prowd of them as I not naturally neat tidy and crafty, essential skills when making these things. If I don't glue myself to EVERYTHING in the manufacturing process its a result!

Cheers!

Here are some pics of my best efforst so far...

The first two are the TDR style canopy and the second two are the traditional canopy style with the vents.

I am getting hooked on doing these now :-)

The traditional style one weighs in a 2.85 grams the real canopy weighs 2.53 but I do have some paper stickers on it.

As I said in my last post I can send out the .cdr CorelDraw 11 files for these two designs if anybody want them. Probably...

Click on the attached thumbnail so it opens as a big image, then right click and 'save as' and save it where ever you want.

Open Pepakura and load the mCPX file from the second download. Then under settings, click on texture setting. Then click on specify texture image and load the .jpeg image. Can print it from pepakura and it prints as a paper folding image with lines for folding and cutting. You can play with the pepakura settings and get rid of the fold marks if you like (that's what I do) Enjoy!
Finally got some ink for my printer to give this a shot. Thanks for all your hard work!!!!
