Default KK Needle valve for TD.049

Hi All,

I want to go 1/2A Proto C/L Racing with the Balsa Beavers

No problems with my (two) TDs, lines, and making a profile plane. or two !

I do not want to win (right!) against many lifetimes of experience!(These Guys ARE Great!)

I like having fun with model airplanes.
(and an excuse to make some 'noise'!)

I'm 'OK' with the stock NV, but seem to be always 1/2 click between rich/lean.
I would like to try a KK NV. (PM me for a price)

I think a simple (non-pressure)bladder tank should work. (Timed 10 laps)

Somewhere, is my piston reset tool, I made in gr9 machine shop!

Wish me Luck! Advice is appreciated.

Why am I so Excited???

Take care,
Have fun,

If you get a Fora, you can beat them!!!  You have a lifetime of experience too. Lots of tipweight. Watch the landings there, it isn't paved for a 42' circle.

Hey Dave, maybe I can rent you my Profi speed .049.. but you have to share in the riches.

Seriously now, some 1/2A proto sounds like good fun.

I'd be curious to know how many KK NVAs were ever sold. They have to be the most popular [engine model specific] model engine accessory of all time..?

Just looked around, I got 4.  two are missing needles.  I think I got an Ace one around too.  That is about how many TD's I have left too.  I wonder how many Babe Bees were sold.  I venture a guess, about half of them are still around somewhere.

Or you can scrounge one from an early Cox product engine back plate with the fine thread all brass needle valves.

The actual needle and barrel used in the KK, TT, and Ace assemblies all originally came from the same source - Cox.

Thanks Guys,

Here are the 'rules', from the January meeting. Next one is Apr. 10th, I'll find out more.

http://www.balsabeavers.com/events/2...01_meeting.pdf

I'll bring my 1/2A box, and see if I can make a trade for a KK NV...

(Just 'found' a TD.020 I forgot I had...Must not get distracted ! ! !)

45 sq.in. min. wing area seems small to me...

I just want to 're-live' part of my childhood. We flew mouse racers at local schoolyards, hopping on our CCM 'Mustang' bikes when we got chased away...

My .25 size 'Re-Trainer' is almost done. It will be used to practice pit stops while the .25 SportRacer(s) are built...

Will keep you posted...

Take care,
Have fun,

What does your .25 Re-trainer look like? Got a drawing?.... We are doing a bit of a push on C/L in our club at present-having just prepared a grass C/L circle at our R/C site. A decent sized .15-.25 C/L trainer design could be useful for introducing other club members to 'hands on' C/L....

They could make a .25 LA race plane.  It is pretty much a trainer.  It used to be Fox .35 racers, but then they changed it to LA .25's,(after I bought 3 crappy Foxes) Both motors run the same speed.  Most Buster, Shoestring, Ringmaster type planes fit into the class.  Wing 1" thick min. 5" from tip, 60 ft. lines...  They work good on grass.  See the Balsa Beavers site for the rules.

Chris -

Here are a couple of options you might consider. One is a kit from SIG, the Akromaster, a 34" profile stunter. The other is the Jetco Shark, a 36.5" profile stunter. Both can be built with fixed or movable flaps, are a simple and inexpensive construction and will fly on a .15 to .19 sized engine.

Thanks for the suggestions-the Sig Akromaster is available here in NZ-which is a point in its favour. 60-ft lines would work nicely-and that's mainly what our C/L guru flies on [I recall my first successful C/L flight-with a flatmate's PAW 149 combat model on 35ft lines........he had the attitude 'if you can keep up with this you can keep up with anything'.......but it wasn't a fun experience.....like being on the INSIDE of a stroboscope!]

Hi Chris,

Longer lines are much easier.
Ever wonder 'why' Leroy sold so many Cox engines?
A: Heavy plastic CL planes on 35ft ft. lines!


I 'designed' my re-trainer, around my old (Magnum GP/Pro, OS FP .25s) that were getting 'toasted' when the OSFX came out.[X(]

I think NIB engines are expensive. And 'completely worn out' engines are priceless !

I fly Maac Scale R/C Combat ( One of CP's famous, High Speed Jousters ! )

I have learned allot about 'coro' construction, ( heavy, but durable ) so...

My entry to the Balsa Beaver 'Beauty Contest' will be my only plane without any balsa!
(Then, you can see pictures ! The stab looks Ringmaster !)

You will like this Chris, the wings are rubber banded on !

I learned FF well before my first engine.

Every plane since, has a 'rubber band, and can glide deadstick' [8D][8D]

Take care,
Have fun,

Some of my worst modelling memories are of trying to learn control line in 1970-and watching other juniors (I was 14 at the time) struggling with Cox reed valve 049s, dacron thread lines-and heavy plastic models that would barely fly, and had next to no line tension-meanwhile I was struggling with overweight under powered wooden models and your priceless clapped engines.....which is why I took up IC powered FF-and was instantly successful (more the pity really-if I hadn't been -I might have persevered a bit more with C/L..........)

Cross Check! Just wonder if anyone flew the 1/2A Proto's and how fast they were moving. Just digging around some old threads.

Piston reset tool in Mississauga:

http://www.greathobbies.com/producti..._id=CXI49RESET

Go to the website and type "Cox" in the search box, you'll be surprised what they have on the shelf. Except for retrofit needle assemblies.

MJD --

I believe almost all the items they're showing are actually from COX International (CXI in their vendor field).

I dunno. But I was surprised at what they had considering this is not normal LHS shelf goods these days around here.

I am sure they are from Cox International, but for Crosscheck and MJD it is handy to just go a few expressway blocks to the hobby shop to get the stuff.

I certainly can't fault that logic --- if items that you need are on the shelf at your LHS, then it's a win-win for everyone concerned.

The downside is that I've never really been able to go to the LHS and leave with only what I planned to buy --- I tend to suffer from, "While I'm here, I may as well get these extra things, just in case I might need them." Since I'm saving gas, they really won't cost as much anyway.

Hi aspeed,
Been busy expanding/upgrading the Brewery, but have got some hobbying/flying in...
(a few float flys )
Could not make the Balsa Beavers Contest. I wanted to count laps for the 100mi Race !
Hoping to make it to the next BB meeting, I'll ask about the proto racing.
I'll ask if anyone there has a KK NV.

MJD, thanks for the Great Hobbies link for the piston reset tool ! I'll order one in, next time I'm that way.
If it is one of Bernie's, I'll be supporting two Canadian companies !

andrew, having 'my list' and going to a LHS, is just part of the hobby for me,,,

Take care,
Have fun,

That is a dangerous store for impulse buyers. The other day as I was checking out I made the comment that I would to hate think how much I had spent there in the last two years. The reply was "Oh, I can tell you that right now! It's right here under your account. Want to guess?"..

So I guessed. I was wrong. Very, very wrong. Oh my..

The LHS where I live has nothing that I would buy and is probably doing me a favor by not having anything that can be used in the construction and flying of small airplanes.
