RE: ECOMRC ?
I used to deal with the manufacturer and only stopped because I stopped dealing airframes altogether. The manufacturer has been around for quite a while and their build quality fits into the top 50% of the quality chain. In other words - they are reasonably good quality but as with most ARF's, it pays to squeeze a bottle of CA into joints where you can reach them and add a little tristock here or there if you want longevity.
Prices are pretty visible if you go to the dealers site.
