I bought a Goldberg Tiger 2 ARF. I like the "tigers" and wanted to have a smaller plane than the Tiger 60 to bring to the field.
The ARF is very complete... even the fuel tank comes assembled for a two line setup.
No real problems assembling it...
All finished, now, lets balance it...
D I S A S T E R ! ! ! ! ! !
The plane is soooo tail heavy that it makes you cry!
No error in construction, remember, is an ARF!
I was fitting it for an OS .50 FX. The instructions say to have the propeller backplate 4 1/8" from the firewall. This way it clears the sidewalls by about 1/4".
Well, I tried setting the engine farther and farther ahead until I run out of mounting bar.
Then I thought that maybe I could fit an OS .72 FS (4 cycle). Being heavier, it would work... Again, I run out of mounting stock.
So, now I have decided to go back to the .50 FX, mount it as far ahead as I can, add a ply backplate behind the mounts and still have to add weight, a lot, in the nose PLUS putting a heavy spinner (bronze) on the engine.
Yes, I tried everything, placing the receiver battery underneath the fuel tank.... nothing balances this beast.
When I built the Tiger 60 from a kit I noticed that it needed weights and a heavy spinner up front... but nothing compares to this plane.
I wonder... did Goldberg, back from the dumps, ever tested the construction of this ARF, which is new in their stable of models?
