Just tried it at Mooloolaba on the flat with small bumps . Not sure why people say the ARTs are hard.. I found it almost identical to my old BSC890. In fact I didn't notice much difference between the two other than the 999 turns better and is much easier to balance (which is also opposite to what I've read - weird). Also it uses the same amount, if not more battery than the BSC (when cruising at speed) - also opposite to what it should do??
So I suspect this is more of a user problem.
Any suggestions to technique. For example while I could catch the bumps ( that were only a couple feet high) I couldnt keep up with them when on foil (no motor).
I added a little negative tail shim that improved it a little.
I suspect most battery used while motoring around - and not sure if I was doing this today but the other day someone said I had the nose pointing too high.
Using old Short Black fuses and 425 progressive tail and 75cm 19mm aluminium mast. Motor at 20cm
Thanks
Those Mooloolaba swells move quite fast as they aren't breaking so you need fast foils to keep up. Your rear stab is quite large, this really slows you down, try and borrow a smaller rear stab and give that a go.
The 999 requires more speed to create the same lift as your BSC890, so you will chew the battery more. As the span and AR get higher, the battery charge life is extended but turning is effected by the wide spans so you need to size down your stab even more.
My go to is the Fireball 1070 paired with the short fuselage and Skinny 30. Gives about 45 min of runtime upwind/downwind.
