Hi Guys,

Picked up a Goldberg Hi Thrust Line Viking unstarted kit a few weeks ago. I am sure the US historians can fill me in on a few details....

1. What was this model introduced into the CG model line up?
2. What year was this model suspended from the line up?
3. Has anyone built one? Which engine? What was your experience?
4. Easy/difficult to trim? How....right/left?.....VTO launch?
5. What flying weight and how covered?

Help me out here?

Regards Ian

Ian,
Which Viking?  It was made in more than one size.  Tha 1/2A Viking is the common one but CG also kitted it in larger size.

Hi Boffin
Cannot help you with age details but believe it came out about mid 60's.
To more practical details, the photo below is of a fellow club member who has been flying one for some time; flight pattern is left - left, engine is Cox 051 on pressure and 30% nitro (hard tank), built per the plan and covered in Esaki tissue. The owner has also built another for a AME 061 which will go like a scaulded cat. I have seen it fly many times and launch attitude depicted is about right for the model (forgot this one is a bit on the porky side at 12 ozs). They will float in the lightest of conditions and love thermals.

Build the kit you've got and enjoy  

The larger Viking which came out in '62 or 3 was for FAI with the motor of choice being the Cox TD 15 (won the 1963 OZ nats in F1C power)

Guys,

Thanks for your help, this seems to be  a model worth building, with a considerable competition heritage.
I have completed the  tailplane, fin and very thin wing already but have to admit that I have modded the dihedral joiner from balsa to ply and used a Kevlar string wrap for peace of mind. Covering will be Esaki over Mylar for puncture resistance and if the covering goes OK, I will start on the fuselage.
I was surprised that High Thrust Line is trimmed left/left but acept that I know nothing about prop wash and its effect. All the more reason for investigating the intricacies of this layout as I would always trim a pylon layout right /left.

Watch this space,

Regards Ian

Hi Group,
nice to be back online here.

Dave's remark about the marketing year appears to be correct, as my first contact with the kit (1/2A) was during my first year at NMMI (New Mexico Military Institute '62-'63).  I had seen a plan in either FM or AAM sometime previously along with a write-up of Carl's exploits with the models and wanted to build one, but the school did not have the proper facilitys and was COMPLETELY MILITARY  .

Unfortunately, I never got around to building one as my parents moved away from Monterrey, Mexico and a nice place to fly FF became scarcer and scarcer  .  Forced  into C/L and RC.

Among my favorite FF planes were: RAMROD 600 (flown-lost), JETSTREAM, TALON, and the 1/2A VIKING.

CHEERS,   Pete
