RE: Vectorflight Edge 540 build
Good sitrep Bunn. That gold trim looks even better out in the open field. I use Futaba radios so I'm not much help on the programming problem. I have learned that you should balance this bird upright and inverted . Then choose the position that the plane falls off the balance point the slowest to do the final CG. Balance it with the tank empty!!
Yup,,, I've been going crazy here with the Dremel tool and the drill and saw. Finished the bottom of the cowl today. Removed over 5 oz of unwanted fat from that alone. Plane with Saito100 weighed in at 8LB 8oz. Plane with OS.91FX (which is heavier) weighs in at 7LBs even. With nothing but the engine, rudder servo in the tail, elev push rods, tail wheel and landing gear/wheels and pants left on this thing I could lift it by the landing gear and it would nose forward. After removing all that excess wood in front of the landing gear area it now falls back to the tail when picked up by the gear. That is a big differance when you can get results like that.
I just now picked the VF fuse up to make room for my 120 and freaked on how light it is now. After proper CG'ing and adding the Futaba 3010s on elevator and ailerons w/6.0volt battery I already know what this plane is gonna do. Slower approaches without that sudden fall from the heavier fuse weight. KE will be much cleaner with less coupling. Rudder inputs (yaw) will be twice as crisp with less mass to move side to side and with the servo closer to the surface. Loops will be smoother and less likely to snap . Vertical is gonna be a hoot after sheading all this fat. The only true weight in the wings is the joiner and the servos. Because they are not sheeted the foam retains it's lightness. And I truely believe that was the only fault in the whole plane's flight character. The wings love to fly. Get your CG too forward and try a fast landing to see what I mean. Better have plenty of space to settle down with.
Balanced perfectly and with less weight in the fuse and this thing should be the nimble power house it was mean't to be.
Nathan,, I have flown the 120 540T and can tell already that the thing will hover just a hair over 1/4 throttle. Yes,,, I over powered it with the Super Tigre G2300 and the 18x6 prop. On the maiden flight I found out why they say to have lower than low rates ready in case of an over responsive plane. Talk about PUCKER FACTOR +++ !! I managed to relax and do the trimming on the middle rates but flicked the switch to low quickly after. LOL... Gonna be a 3/D machine from hell. Hopefully I can handle it. Used 25% expo,, will raise that by another 10% next time out. I had to cut the maiden short because of the G2300 losing power. I ordered a Perry Carb and it came today. I'm hoping it will make the break-in period a little less nerve racking cuz I sure would hate running several gallons of high-$$ nitro through it while it sits in a tail stand. I wanna fly that fuel !!! Not watch it blow out the exhaust .
