As stated, follow the directions and be patient. You don't need jigs if you build over the plans. The good kits are very easy and you should be able to build them just fine. Don't worry about cutting holes in it to lighten it up. If they wanted holes in it, the MFG would put them there. Follow the directions and you will be fine. Great planes, Goldberg and sig make great kits with good plans if you start with one of those.

Good luck. Have fun
