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?!..............
