RE: Goldberg Extra 300
Looks like you are doing a very nice refurbishing job and I'm sure you will feel justified for all the effort you put into getting your model back in shape by the gobs of pleasure you will get from flying it. But do yourself a favour and get an aluminium landing gear as it will stand a lot more abuse than the stock wire one, and tilt it forward as much as possible to counter the model's tendency to nose over especially if flown from a grass field. Of course some stick back pressure during the take off run helps alleviate this problem.
