Looks good Dale. Wish I was flying - still snow on the ground and a soggy flying field here in Massachusetts.

motor thrust

I've been following this thread and have not read anything about the up thrust in the VA. Is it just mine? I put a incidence meter on mine and showed 2 1/2 degs. of up thrust. So I put a couple washers behind the top mount and ended up with 1 deg of down thrust. I also put a Dubro electric spinner and a 11x3.8 apc as someone here sugested. Flew it today and noticed a nice improvement in verticle speed and it also seemed to hover a little easier. Had to cut the flite short because I'm in Michigan and fingers were freezing after about 4 min. I found it strange though that I didn't need any additional trim in the elevator after making the motor thrust change. If you make the change the spinner will no longer line up well with the fuse. When it gets warmer and I can get more flites on it I may change the thrust back but I've been flying for 20+ yrs and the rule has always been a few deg's down thrust and right thrust.

PS..what is a turkey roll? Ron

Yes, i know, I should have such device but if somebody figured out a perfect prop I will use this recommend prop too.
Thanks !
I would be VERY CAREFUL using a 12x6 without knowing the actual amps it draws.................

Props: Stock vs. APC 12x6

OK...I chipped a prop on landing and the LHS was out of the OEM props. So took home the APC 12 X 6. (There are no props I could find with the stock Dia X Pitch from any other maker).

First, the wattmeter (static test):
Stock 12x4 @ 1/2 throttle=10.98a
@ 3/4 throttle=34.13a
@ Full throttle=44.10a

APC 12x6E @ 1/2 throttle=13.45a
@ 3/4 throttle=42.15a
@ Full throttle=50.16a

Actual flying: The plane seemed a bit faster with similar performance in other respects. Will need more time to see the flight differences, but the run time is maybe a minute less to similar discharge and mixed flying.

Not sure how much headroom the stock ESC has, but should be ok in the air.
The APC prop requires reaming to fit the motor shaft. The stock spinner fits, but does contact the blades somewhat.

Dale, you must have set your gains for maximum grooviness. You need to go back and read that this is an underpowered highwingloaded brick and stop trying to deceive us by making it look floaty. Flat, most 3D planes have little to no thrust angle (easier to hang from prop)

You can buy an inexpensive 5mm shaft prop adapter which will accept the APC electric props "as is" - HH has em as do others your spinner will not fit this but they have a little bullet end -with a hole in them.
another propwhich you may like is the APC 13x4 electric - - if amps are too high for you, trim and balance the prop 1 little bit-I use this prop on my Fun Cub for VTO full flap takeoffs. ( EFlite 10 motor)

don't bother with thrust adj or try to mix controls -or other pattern plane adj- the AS3X tries to hold the last line you input
Around here, a turkey roll is like a lobster roll only made with turkey- Not to be confused with a roll in the hay

JUST saw your video of VISIONAIR,,,,wow our style of flying is very similar ,except for hovering,, U do it better and lower .the best i have done is about 15 ft up with no wind

I have my DX8 set up so that the Sport and 3D are on the gear switch and the High and low rates are on the Elevator switch. I have the DR/Expo that is on the Elev. switch exactly as the manual describes. I mainly fly 3D and just use Sport mode for take off when I feel like I need it. By doing this am I missing out on any of the capabilities that the Visionaire is capable of?

Brian is an awesome pilot. He does everything way down low and right in front of his face!

Guys be carefull with the APC 12x6......high chances you would damage the motor.....Specially when weather gets warmer. Not easy for ESC either. Check current before you make final choice and compare to stock prop to make a smart decision.. During all my developing test the provided prop design/size and motor Kv showed best match to the airplane performance/design.
The VA needs that up motor angle, please do not change that angle. The motor angle is very relative to CG. Check CG and do the inflight test we recommend in the manual and also I post here.
The motor, wing and stab angles are all relative to CG. The plane it is set with those angles and CG to delivery most performance in the entire flight envelope/maneuvers.
Thanks.
