I got back into the hobby about a year ago, & have got 5 kits which are up to the point of exterior painting. From my last time around in the hobby, I dont have any real issues with the construction of the kits, however I have never airbrushed before & will be airbrushing these kits (help).
While none of the kits are rare, 3 of them have not been in production for some time, & one in particular I dont want to make a backside of - it's an Ertl XB-70, which I paid a fair few Quid for.
I started building on the XB-70 first & came across some serious filler work required, so I put the XB back on the shelf & switched to the Italeri B-58 & used the time away from the XB to ask some questions here & figure out how to best solve its issues.
If you are in any doubt about starting these specific kit because you dont want to hash them, go & buy an inexpensive kit with no big issues & throw it together - if you arn't happy with the quality of it when finished, do the same again. This should give you the confidence to have a bash at the kits you really want to do - & if you have problems, come back here & ask.
I had to ask how many bottles of Tamiya paint I would need for the XB-70, I didn't know if I would be looking at 1, 10 or anywhere in between, but someone answered that question for me.
