Hello, you will enjoy in building and later in flying this model. I made two Ziroli Hellcats. First was little heavier 22,5 kg, but fly well with Evolution 80.
On second I take care about weight, so it was 19,5 kg. On that I use Zenoah GT 80.

More about my Hellcats you can see on my web site: www.nsmodelers.rs

I can also offer you Detail set, dummy rivets ans some other sets for scale finish on surface...

Regards

Mirce
