This got me thinking, a 2.4gHz R/C car Tx with telemetry. With mods to the electronics from the vehicle, it could take a lot of R&D work out of how to transmit storm data to a laptop, for the Storm Runner project

Saying that, news this week is that my residency has been nullified !
The Chicago office of USCIS has denied my residency application and I am now here in the USA illegally.
Bought and paid for house.
No credit cards.
All documentation asked for has been supplied.
No criminal convictions.
No problems or incidences with law enforcement.
Married for 2 years to my American wife.
The only delay was with the Affidavit of Support, because of problems with the economy noone felt able to sign. Threatened with deportation we made the official appeal as instructed and through generous donations by friends and yard sales etc were able to meet the filing fee. Then we gained a family members signing of the form when he realised the gravity of the situation. All paperwork returned in the allocated 30 days.
Residency denied.

Currently attempting to gain info from a related messageboard and from friends who have been through the immigration process.

There may be no Storm Runner taking to the skies next year, that may gain valuable data for the scientific community and, help save lives.

nuther project I have wanted to try for awile,.. will let you guys see progress as it comes,... here is a screen capture to kick it off

Motor turning over to slowly with the electric starter??

I needed a 24 volt battery to use on my electric starter for some of my bigger engines and even in the cold on a few of the smaller then bigger engines.

So after searching on line (not extensively) and found nothing, I made this box which is two 12 volt batteries with a switch to go from 12 volts to 24 volts. It has worked out fantastic for me so I thought I'd post on how to do it.

this is a step by step procedure built into the pictures, the box was already completed when I did this so most of the pics show the finished product.

I present to you the Waldotorque double 12-24 extreme starting system.

Is it extreme? absolutely not,, but everything today is extreme, so why should I change that. :D

You can also charge the two batteries without having to open up the box or disconnecting anything. just put the switch to 12 volts and attach your charger to 1 side of the box, put the clamps on the other side and then charge that battery. I'm not sure if you could charge both at the same time with the switch in the 24 volt position but if I find out it is safe to do so I will post the results in an update.

UPDATE already : LOL instead of using the Machine screws or Bolts for the battery terminals it would be much wiser to use Banana plugs to plug into on top of the box. Thank you majortomski for the suggestion.

I didn't want to crowd my F-22 build thread with these small build updates, so I decided to create own thread for those to my blog.

So lets start the thread with first post that shows for I created ejection seat. This is far cry from those scale cockpits on most jets, but jets just look empty without cockpit.. and I didnt want to pay 300$ for one.

My ejection seat is loosely based around schematic view of F-16's ACES II seat. I build frame from balsa and then started to layer more balsa to add details. To give some texture to seat and back cushion, I covered 1mm balsa pieces with fabric netting.

Pics speak louder than words.. so here you are

oh..sorry again.. some pics are taken with my crappy phone cam

I'm not usually very good at keeping blogs up to date so don't be surprised if this is the only entry for ages to come...

An awesome DS day was had yesterday at Rushup, UK with some other RCG members including DSMan and Zimofile. Everyone except the UK record holder (Mark Abbott) chalked up new PB's. Mark's PB of 237mph is so spectacular that it's always going to be tough to beat and falling 10mph short at 227mph was downright spectacular nevertheless! For the rest of us it was onwards and upwards.

The following speed details are replicated in the Speed, Plane, Person, Location... DS thread: http://www.rcgroups.com/forums/showt...43385&page=112


Today's speeds (witness/radar gunner in brackets):

Mark Abbott:
Opus MCT 227mph, (GB/George Pilkington?)

Graham Bridge:
Opus V 185mph, new PB, (KS)
HP60 154mph, new PB, (KS)

KS (Kiwi Steve Rainbow/Hot Air):
Mini Blade 154mph, new PB, (GB)
Balistik 122mph, new PB, (GB)

Warrick Smith (Zim):
Splinter DS 162mph, new PB, (George Pilkington)

George Pilkington:
Mini Blade 148mph, new PB, (KS)

he scammed me so be careful

well, lately I have been working on the "Lazy Boy II" it is an electrig 2m glider made from blue core 6mm foam. It is an Easy build and since I am new to flying it was fun and very easy to build.
My biggest problem was i got impatient and tried to paint it using krylon fusion paint supposedly safe for plastic. Well, do I need to say any more ? yup you guessed it. I ruined all my work. so now I have to start form scratch once I get back from my trip. It was looking so good too.
I ordered some "towerkote" covering to practice on foam as it said it was a super low heat made for foam and other stuff. so i will practice with it on scraps of foam before I try to cover my new lazyboyII and see what happens. If nothing else i can always resort back to permanent markers as I know they do not harm foam.
well that's iot for now.

Just A Couple Of Pics Having Fun At The Pond With My Pro Boat Miss Elam

RC Servos

RC servos are electro-mechanical devices that respond to a control signal, which instructs them to move their output shaft to a certain position. A servo is normally plugged into a radio receiver with a three pin connector. The three wires are power (usually 4.8V to 6.0V), a ground wire, and a signal wire. The signal wire carries a PWM (Pulse-Width Modulation) signal consisting of a 1-2ms pulse repeated 50 times a second. A 1.5ms pulse will tell the servo to move to its output shaft to the center position, 0 degrees. For a servo with a 90 degree range of motion, a 1ms pulse will move the servo to -45 degrees, and a 2ms pulse will move the servo to +45 degrees.
Servo Specifications

Torque

The torque rating specifies how much force the servo can exert. It is typically expressed in units of ounce-inches (oz-in) or kilogram-centimeters (kg-cm). The higher the number, the more force the servo can exert. If you know the length of the servo arm that will be used, you can use this measurement and the servo torque rating to calculate how much force end of the arm can exert. A long arm will reduce the maximum possible force, and a short arm will increase it.

Speed

The speed of a servo is measured in the number of seconds it takes to move a certain amount of rotation, usually 60 degrees. The smaller the number, the faster the servo is. A servo that is rated 0.15 seconds is able to rotate 60 degrees in 0.15 seconds.

Size and Weight

The size and weight of a servo are important considerations when used in a small airplanes or other RC devices where there is not much room, or weight is an issue. Typically, smaller servos will have lower torque ratings.
Bearing Type

Standard servos have bushings supporting the main shaft, heavy duty servos typically have one or two ball bearings supporting the main shaft.

Motor Type

The standard motor used in an RC servo is a three pole ferrite motor. Five pole coreless motors are used in some high speed servos, and heavy duty coreless motors are using in some high end heavy duty RC servos.

Being trying for 5 weeks to have Banana Hobby honor their promise to replace a defective part. Almost impossible to talk to a human. After 2 live chat promises and one live person promise - still waiting for the replacement part. Not the best way to attract customers!

The endless joy of making hot-wire templates.

I don't mind it actually, but I was growing tired of the job while finish sanding the last one or two. There are a lot of templates needed for this design - the wing templates are on the right while the fin/stab templates are on the left. The templates are formica. I rough cut them with a jigsaw, sand them to within about 1/2mm on a bench mounted belt/disc sander (best tool ever) and then finish them by hand with a variety of small sanding blocks, some custom made for the job.

PS. In the pic below I've cut away about 2mm of the paper near where the hot wire will run to make sure the paper won't get in the way.

I've just started building a dedicated DS plane. The design has been evolving in my head and on the computer for a couple of years now.

Vital stats are a span of 2.3M, a bagged wing, and I'm shooting for a flying weight of 3.5KG. The plan is to build most if not all of that weight into the structure rather than carry ballast, which should keep things nice and strong. Other than that I won't go into any more detail but will instead let it reveal itself as the build progresses .

RC Rims / Wheels Database
RC Rims database
already up, but I still have issue with two way connection between RC Rims and RC Tires.
This database have several data field that we might consider when choosing rim for our vehicle, like hex size, offset, outer diameter, width, weight, tire bead, etc.

Often we use rims that known used on our vehicle, but there is many other maybe thousand option that might usable for our chosen tires.

We just need to buy and try if it fit, WAIT!! what a waste if it didn't fit.

Therefore this database can help you and save our money, ONLY if it have data, right?

In perfect condition, the data must be collected from user by measure the part, so we can have real tested subject. Otherwise it will have incomplete data or slightly inaccurate.

But in real world, like what going on now, I use GOOGLE to find data, a time consuming process and incomplete data gathered, well at least I don't make a big hole in my pocket to purchase all parts.

Jimmy

I have bought a Black Horse JC Piper Cub as my first RC plane, and I'm finding that there are parts missing and in some cases, parts left over.

I am in need of some aileron horns and fixings, my local shop cannot supply me, he says the type I want should have been in the kit, but I am one short.

Can anybody suggest a place in the UK who supplies all these bits? You must be able to buy them, because if you make your own plane from scratch, then you would have to get all the little parts and accessories that you want....Surely

I pretty much always have a few rolls of this foam wrapped up and ready to go, so pm me if you ever want any.

It's 3 grams per square foot and made from styrofoam, perfect for small planes. It takes printed tissue really well and is very easy to work with.

It's $25US per roll, including P&P (airmail, usually takes about a week to get to you) to pretty much anywhere in the world (USA, Can, Aus, Brazil, etc). A roll is 30' long and just under 2' wide, giving 58 square feet in total. I guarantee that all but the first 5' will be in perfect condition, aside from 1/2" in from the sides. This is because the only way I've found to make it economical to post is to wrap it in brown paper - corrugated card almost doubles the price due to postal charges. For every linear foot damaged beyond the first 5' I'll refund at the rate of $1US via paypal, and I'll send it as a gift so I absorb the charges, i.e., you'll actually get a dollar in your account. To be absolutely honest I've only ever had to give a refund once, most people seem to be able to use all 30' of their rolls. Of course, if it gets lost in the post or completely destroyed I will replace it at my own cost as soon as possible.

Basically, this works out at 50c per square foot, so it's a really economical material.

Here's a link to a thread about how to work with it - www.rcgroups.com/showthread.php?t=1052824.

I can do a discount for 2 rolls ordered at the same time and delivered to the same address, any more than 2 rolls at a time the postage goes up because of the volume of the parcels. This discount is two rolls for $40.

Any questions, just ask.

Finally decided to add something to my blog. This is a list of sites that I find useful and others might as well, though I am largely writing it for myself so I don't have to carry on searching for things I've found before... I'll add to it as and when.

A few months ago, I purchased a couple of Heli's. Both seem to have problems.
The Blade 400;
Each time I try to lift off, the heli will spin. I tried sticking in one direction & the other, it doesn't matter.

The T-rex;
I have replaced 2 servos & tried different motor controllers & still cannot spin the motor. I have been able to bind the receiver to my dx6i. I get the tones from the motor & tried 3 different controllers. 2 are brand new.

The only thing I can think of is the gyros on both heli's need replacement. Please let me know your thoughts.
Thanks,

So, since my last entry I have torn down the SuperStar 40 that I had acquired. It had been the project of a high school student who apparently could not read and had few mechanical skills. Luckily the plane was mostly repairable. After re-assembling the wing, rebuilding the servo tray and adjusting all the linkages the plane is in pretty good shape. It came with a OS .40 LA and that will do for now. I had an older Futaba 72 mhz tx and rx, so I used them.
So back to the field I go. My instructor checks everything out and says "Not bad" which makes me feel good. We hook up a buddy box and check out the controls. Had to reverse a couple. Then he takes off as sets the trim. Now it's my turn and I hear "You have the plane". I fly a race track pattern making right hand turns, then left hand turns. I'm over controlling like crazy and my instructor has to take the plane several times as I spiral out of control. I'm sure glad he is paying attention. After about minutes I am worn out, so he lands and we review the flight. Actually I didn't do too bad.
Three days later we are back at the flying field and I get in two 10 minute flights and do much better. Still a little over control and some confusion when the plane is coming at me, but better over all. And I wasn't nearly as nervous. I'll be back flying this weekend.

So I crashed the sukhoi, actually crashed it and bent the prop shaft. I got some 5043 props, a prop adapter, a new prop shaft and a P-51 motor because I need more power and dont feel like doing the brushless upgrade yet. Should have it together tonight but I work 3rd tomorrow so I wont be able to fly it until sat. morning. cant wait
