Hi Dikoz,
I don`t think that it is that hard to build the Aviomodelli Piper. I started my Arrow in October 2003 and finished it in February 2004. I only worked in the evenings 2-3 times a week. So far I`ve already built ARF`s
The wing is made of styro an abachi, you only have to cut out the ailerons and flaps. The fuselage is real work but the wooden parts fit very, very good!
For detail works you will need some experience e.g. mounting the front wheel or fitting the horizontal stabilizer but if you have already built a J-3 Cub in 1:5 I think it could work!
Are you really shure that your friends are talking about the Aviomedelli Piper? Top Flite also offers a Piper Arrow. I`ve seen the kit and I think for that kit you must be an expert.
Just have a look at
www.fmv-leingarten.de in "Pictures" you can see my Arrow II in its "safari outfit"
