As with any lower priced ARF you will need to double check a few things like glue joints, firewalls, etc...I did pin my firewall on my Extra as I noticed it seemed pretty weak and also beefed the landing gear block area. I had well over 25+ flights and was just really starting to wring it out when it met it's demise.

I also did replace all of the stock control rods with Gold'n rods as the stock rods seemed very weak, read that as flexible.

Now I know there will be those out there that will say, this is an ARF and you should not have to do things like that. Well, I have seen higher priced ARF's from larger named companies that needed much more than that and without naming it mine required a complete rebuild of the right wing after finding all of the ribs cracked and there was a backlog of wings and the replacements were coming in damaged.

I have seen the opposite. You spend a little and get extremely great quality and customer service, although the selection is somewhat limited.

Just go over it pretty good, strengthen and brace anything that even remotely looks marginal and you will have a very good flying plane.

Oh...sorry I did not know that was a 40 sized plane. The pic of the engine on it made it look like a 60 size
