Goldberg Super Chipmunk

Bought this Super Chipmunk 63 inch wingspan on Ebay at least 8 years ago and has been buried in the back of the hangar ever since. It was a Carl Goldberg kit before Goldberg made an ARF version. It was powered by a sweet 65 four stroke which I sold on. I was planning to give it something more lively and redo the covering which was faded to say the least. That's when lack of interest came up. Ruddy covered with Monokote (they should hang the guy who invented that). The top layer comes off leaving a ruddy mess of pigment and glue. Made a start on it and then gave up.

Wind forward to 2020 and held hostage indoors by bad weather. Took another look at it and another attempt to get a bit more Monokote off. I then made a servo tray and found some old pushrods for the rudder and elevator. Made up guide tubes from snake outers. I have a new fibre-glass cowl that came with it too fortunately. Last two days I have recovered it with Oracover (with colours I had in stock) because I am not spending to much money on it. Two new digital servos though. Will be looking for an 70 -80 size four stroke for it. Salisbury MFC have a Swapmeet in April so might find one there.

It is real struggle sometimes recovering. Much easier to cover individual components.

Images show progress so far

I may be going to the Romsey swap meet on Sunday if you want me to look out for a motor.

Ah Yes Simon! Forgot about that. See you there.

There are a few 70-80 4 stroke motors from Stuart's estate that are still available, 2 x Saito and 2 x Lasers if that's any use to you.

Thanks Jon. One of them might do the job. Where can I take a look at them to see if they will fit with out me hacking the cowl to bits.

Just realised it is in March not THIS Sunday! :S

You are right Phil!

Dug out the wing which was in Art Scholls livery which I did many many years ago. Time has taken it's toll - the strips were peeling off and the base covering was lifting. Oh well, complete strip off then. I remember when I bought this Chippy it was designed for the old fashioned centre servo idea using a bell crank for the ailerons. :whistle: I remember now that I modified it for servo per aileron. It must have been a long time go because the servos are Futaba 3003.....:whistle: I have repaired the hole in the top surface next to the fuselage. I have also cut off the wing tips so it will now be known as a "clipped wing" chipmunk. On the downside I was only over Probuild only a few days ago for some bits and Oracover but looks like another trip shortly, will be running out White again. While the wing is open I am mulling over whether to install position lights/strobes.

Hi Phil

I have on of the Saito 82's at home at the moment, you're welcome to borrow it to see how it fits if you like. I'll be around all weekend if you want to pick it up

Thanks Jon. I will ring to check your in first. I won't be flying this weekend....:lol:

Do they use the same exhaust thread as ASP for instance?
