PJ, so i am guessing that Phantom modles are just naturally nose heavy. I always secure my models to every base, with aircraft i will drill a hole through at least one wheel and insert a piece of wire and then pin that into the base. I think even if you went for the folded nose option it would still be ok as you would have the addd weight of the radar.
And thank you, coming from you with your Phantom line up, that means a lot.
Hopefully i won't have to wait to long, and i will be looking forward to seeing what you can do with it.
