Is that true, Goldberg kits and in particular are out of production?
They are currently unavailable here in the UK, mores the pity.
As previous modelers have said, they are great flyers and the kit is (was) good.
I go with the "mods".
There used to be a kit with f/glass cowl and pants and wing fuselage fairing. A bit more expensive.
Anyone with update on kits?
If so, where is best place to purchase?
thanks

Some of the Goldberg kits are available on Tower hobbies, so some one is building them again. Not yet available in the UK as far as I know. If you are desparate Tower hobbies will ship to the UK but you have to pay a fortune in shipping (and run the risk of damage).
My Chipmunk is my oldest surviving plane, nearly 3 years old now. Plenty of other planes have come and gone. Starting to look a bit tatty though. It was my first scale kit, and I didn't really know what I was doing, so it came out heavy at 8.5 lbs!
Started out with an OS 61 FX (butchered the front end to fit the standard silencer!) but now has a 91 FX (needed to haul that weight around)
Because of the weight, the wing loading is a bit high (over 28 oz/sq foot) but still floats in for a nice slow landing with the flaps down. I use my computer radio to adjust the elevator trim to correct for the flaps. Very smooth flyer though. UK readers will understand this: used my Chipmunk to learn and pass my"B" certificate.
Tips:
Keep the weight down!
Don't worry about the wing mounting blocks. Mine are as per the instructions, I have snapped the wire undercarriage legs twice, but no damage to the mounting blocks.
Use thinner grade undercarriage wire, especially if flying off grass, as it WILL bend backwards, causing it to nose over. Thinner wire makes it easier to bend back to shape.
Would I consider having another one? Probably.
Perfect engine? I would say the Laser 120. By my calculations, it will fit completely inside the cowl if mounted inverted, and has plenty of power to pull it though any manouvers.
Why do I end up writting essays?!..............

They told me all their kits will be available again shortly. Whether this is really true, time will tell... New company but same kits, supposedly. I hear some may be modified, however. May just be rumor.

Hello All,
Here is my CG Super Chipmunk. Blue Angle No. 5 (opposing solo), custom cockpit with HUD (head up display). Ole K&B 61 that pulled it around like a scalded ape! Flaps, bell crank ailerons (worked fine for me). My inexperienced thumbs were pulling out of a semi low pass, over rotated to inverted, panicked, and you can guess... pulled up. Complete loss. Beautiful plane and if I ever start building what I once had, I will build it again. BTW, all graphics are hand cut monocote, very time consuming.

Pretty plane, only one fuss point.
The bend in the corner is the angLE, the heavenly beings and the USN's blue things are angELs.
Sorry, the "Blue Bends" just grates on my eyeballs.
Bill.
PS: Hope you build new, and have a longer service life with the next. wr.

Would like response to original question (to which one guy has replied), and that is, are the Goldberg kits back in production. I noticed a wbsite for a Canadian hobby shop which gave prices etc for them; in particular the Chipmunk, two prices on forthe "plastic" parts kit, the other for F/glass parts.
ARE they back?

Powered mine with a ST 61- Plenty of power and just a really fun airplane. Put flaps on- they aren't needed as it slows down just fine, but they are a lot of fun, and they look good! Enjoy!!

This is good news, but I was under the impression that it was Lanier who took over the Goldberg line. Or has Lanier been taken over too?

Sorry, the Great Planes consortium (GP, Tower, Hobbico, etc) has taken over Carl Goldberg. They say all kits will be in production.
Best,
Kelly

Bill, thank God. I was definitely thinking Lanier must have been swallowed up now too. More manufactures mean more choice and better prices.
Best again,

BOLT:
THERE IS A BUTTON ON THE LEFT SIDE OF YOUR KEYBOARD THAT SAYS "CAPS LOCK." PRESS it. Thank you.
Now. The OS 120 on a Goldberg Super Chipmunk. You will not have "Too much" power, as there is no such thing. But you will be hangine a two pound engine where a 14 ounce engine is supposed to be. Too much weight.
A K&B ringed 61 would do a great job on that one, or in four stroke a Saito FA-72/82. But not the OS 1.20 Surpass engine, please.
Bill.

Bolt,
Back in the 90s when I built my first CG Chipmunks, the first one flew on a K&B61 and the next one on an OS91FS
Both flew extremely well with lots of power to spare.
I had issues with the K&B where I seemed to have fuel draw problems but when I added a Perry pump, it seemed to fix it.
I agree with Bill, a FS120 is a bit over the top. You want your Chipmunk lightweight. These are amongst the best flying planes you can get your hands on and should be built light.

I built one in 1987 and I think the Tower price was $69.00!! It had a Enya .61, flaps, was covered like the box and flew great. Reading this thread makes me want to do it again. This one never wrecked but was retired after about a year as I needed the radio & engine for other planes.
Does anyone know if there have been any modifications over the years to this kit? If not, maybe I'll overhaul the one I have. It should be interesting taking the covering off and seeing my level of craftsmanship 17 years ago! hehe I won't be posting those photos in the bare bones.

I just got mine up for the first time a few weeks ago.
I have an Magnum 91 that Bill recommended. I like it, it seems like plenty of power, but I will have to admit I've seen a chipmunk at our club that could go a lot faster.
I had to add A LOT of weight to the front to balance it. I didnt' actually determine exactly how much I had to add, but it was several pieces of lead I epoxied to the engine mount.

Hi Wings,
I'm sure your Mag91 is an excellent motor for the Chipmunk. Even if another Chip is faster, remember that the Chipmunk is not a patricularly fast plane but very agile. It's perfect for a good 4 stroke.
Look at www.artscholl.com for some info on the original one and some videos. There is also a huge amount of litterature available on Art.

As far as engines go, I got from another thread that the OS .61FX and .91FX weigh almost exactly the same. Mine flew great on a .61FX. Another way to balance it wihtout adding a lot of excess weight is to reposition the elevator and rudder servos out to the tail. It helps account for a heavier engine, and allows you to use shorter, less flexible linkages.

Wings,
I'm building one with a TT .91 FS which is several ounces heavier than your Mag .91
I've been told that the TT also produces a bit more power...more on par with a Saito 100. A little late to switch but maybe something to consider if you ever build another .91 size plane.
By the way- did you have to grind down the wing mount supports to make room for the flap arms? Did you replace the wing mount bolts with nylon or did you use the ones in the kit?
Thanks- and post some photos of your plane!
