Progress as at 01 Apr 08
Last weekend quite slow, due working.

Paneled gear/fan/intake sections. Now panelled from B1 to fan rear. Fwd fuse stiff as a board!
Fan mounted properly; B8 cut out.
Wing and canard cut out.
All bulkheads installed on stb side.

To come:
Panel 4 rear sections
Build intake / exhaust cones
Cut out intake/exhaust from bulkheads

Random thoughts:
Intake: 3/4-3mm-3/4? Blue foam plug, slice'n'reglue?
Power upgrade path. 7s and new escs, or new fans?

Pics attached.

This is a 800w Jepe F16
Spider fan, Jeti Spin 66 ESC
5 S 3300 mah Lipos cells, 2 Futaba 3450 digital servos,
AR 7000 receiver, Radio is 9303 JR
I just both a new DS 51 Schubeler fan and a Neu motor for this model.
Picture was taken March 29 , try to take off on the snow withouts success!
Very light model and excellent Jet easy to fly and land

Wrote a cheat sheet for the swashplate. Tweeked the video recognition. Have the cyclic alignment down to just feeding in a phase & the computer figures out the blade pitches for the disc.

Well, the phase ended up being 15' instead of 30' like it was before & still is on the rate damping.

Neural network mixing works & is a lot neater than the algebraic method so it's staying. Have hardly flown the T-Rex in manual mode at all since its birth but a backwards figure 8 definitely felt easier with neural network mixing & the phase tweek.

Stepped up the cyclic gain to where it oscillates & got more turn stability. Oscillation is caused by the neural network velocity predictions. Stepped collective P gain back to 0.01 & got the usual less stable altitude but no vortex ring states.

Did an endurance test & our oldest 3.3Ah battery hovered 10 minutes in ground effect. It's previous flight ended after 7 min with the camera payload. This one is mainly used for test stand operations.

Well, like millions of others, got charged $4 by The Portland Chap & the credit card had to be disabled. All it takes is 1 insecure website. Charge $4 on a million credit card numbers. No-one cares about a $4 charge, but U just made $4 million.

No camera replacement this week. The total amount of fraud between Blockbuster accounting errors & credit card charges is $30 this year. Over 30 years, that could end up $900 just in fraud.

2 weeks after ordering, said they shipped the next round of batteries.

thought i'd just share a few pics of the sort of stuff I've been getting into over the last couple of months. i decided to start to build some aircraft. the aim was to get my son into modelling (and grow some patience) worked. however it got me interested again.

They are humble beginnings.....probably building things incorrectly, however, with the amount of help on these forums i have quickly learnt the errors of my ways.....and lodged the trick of the trade into the memory banks for next time!!!!!
I started with an Aquila saiplane 102" wingspan......and moved over to anothe build of a small electric flier.....the S.E 5a WW1 biplane. couple of basic muck ups here and there.....but hey.....its a start.....

By the way.....the SE 5a....was going to be a quick foamcore build for my son to fly...but it ended up a bit of a hybris...with balsa as well....interesting...but i will not do it again that way.....

Mmmmm, 1903.

Just doing a little hotlinking to a Springfield 1903 collectors forum (who new there were such things). Need to get a replacement stock, but they're hard to find...

Here's another video of my Carbon Falcon. Levier's video was so good that I didn't even edit it, but left it as one continous clip. Includes a hand catch at the end. A lot easier to catch that a Zagi.

Hello again,

I now have some inflight pictures of my Northstar. This plane turns out to be a very nice flying plane with great flight characteristics. All I can say is this thing is a blast to fly down low at full power with the engine screaming and the thing just roaring by. It's awesome!!!!!!!!

This should be a lot of fun!

We all have other hobbies, I assume. One hobby is more than enough to take up all your free time, but at least most are not satisfied with just one.

I do video editing and filming when I can - mostly for home movies and mostly for people I know. It's a lot of fun though and I wish so much I could go into it as a career someday. But for now I'm satisfied just doing it for fun.

I have other hobbies like writing - mostly poetry. The one that is newest to me though is drawing. Since my hubby got me into anime, mostly I draw in anime style, but I'm trying to branch out. Anyways, here are a couple of the ones that I have finished:

The new design is coming together nicely. I'm going to cover it this week so she should be all finished by the weekend. We've still got snow here so the maiden flight will have to wait for about a month since the field is pretty wet in the spring.

I'm really happy with how this one turned out and it looks like I'll be way below my 5lb goal. It's looking like she'll be under 4lbs ready to fly!


New Beam 450E

Just thought I would post some pics of the new Beam. I wasnt planning on buying another 450 class heli but I'm sure glade I did! I will be posting more pics once I get all electronics installed!...Continue Reading

Hi to all you good fliers out there. Is there anyone out there who as this FMS flight sim that works can they in simple terms tell me how to get it to run on my computer that as windows vista programe on it.- it has so far drove me nuts trying to make it work.I keep getting dmll no loaded but I have downloaded it & run it but still no way

Well, we got a lot done over the past few days. Its getting there. If you are wondering why the roof just kinda "stops" like that on the left side, you will know soon enough!

We also have some nice windows we will be installing. Courtesy of a CH-47 that is in for phase maint. Should be pretty neat.

Then comes paint and interior... lots left to do. But, it gives us something fun during our "down time".

I think we will need some flower seeds and the like. We could build some planters on the outside walls for flowers. That might be a nice touch.

Hello! I'm new here , I saw a post about a big electric airplane. I live in Greece , so I can't find here any magazine to see plans..I need to make an A319. Can anyone tell me : What I will need , how much it will cost , where I can find the stickers for the decoration and where I can find plans to make the A319 RC

Thank you


(reply here , or on my thread)

Did some good flying this weekend, as the weather was perfect. Seb's Calmato sport was performing some high-speed passes (plane crashed later in the day ), and a T-Rex 600 nitro with a scale model body successfully tried to lift a blanket.

Probably the first time that I flew with 3 different types of planes in the same day (morning actually): Fusion (3D depron plane from Donuts Models), T-Rex 450 (heli), and EasyStar (to do some AP of the field).

I just received my new radio: a Futaba FF9 (T9CHP) that I bought used from ebay. It looks like this radio has everything that I could dream of. I was starting to feel the limitations of the FX18, that I will keep as a spare radio. More news and photos later !...Continue Reading

The answer is yes. U can mix a swashplate with a neural network. Most of the time, it works. Made really rough video & an LED tracking program to train the network. The head would always rotate during the tests. The linkages had a lot of play. The camera couldn't be exactly level. Video synchronization seemed to work.

Have a really rough conversion of cyclic to pitch phase in the disc. Since the goal is isolating collective from cyclic, phase alignment is secondary.

Video of training the neural network using machine vision followed by a strapdown test of neural network swashplate mixing.

Swashplate mixing with a neural network (1 min 51 sec)

Well, she certainly flies like this. Can't say it's any better than algebraic mixing. Swashplate phase is way off. Have some nasty glitches when the wrong combination of collective & cyclic is applied.

The credit card is nuked. All things considered, the EOS 5D is only rent inflation since last year....Continue Reading
