Never seen that boat before, but looks to be designed to RG65 class rules… Difficult to know without measuring it…
In any case, from the pictures I found and the product page http://helion-rc.com/aura650/ , it looks like it would need some mods to make it work perfectly. Some I can list from the pictures are:
- make the vang adjustable (you can buy the one supplied for the DF65)
- change the closed-loop sheeting system by a open-one with elastic (much more reliable). Sheet comes from the drum to the outside, to the transom and then back and is attached near the bow with a 15-20cm elastic - this elastic keeps the tension so that sheet does not fall off the drum. No drum cover needed.
- completely change the way to rig the sails. Look for instructions for a RG65 sailboat. No topping lift for main boom. Forestay should run through the inside of the jib. Both sails should have adjustable cunningham and outhaul. etc.
- probably change the stock sails for better ones (they look badly shaped in all those pictures)
In any case, start by making it sail, then go to local club and ask for advice… then change one thing at a time and learn to sail better each time. This is a great hobby, no model crashes, and plenty running time with a single battery charge. Have fun!
