Guys: I am looking for data on the new Ava Pro Flapped 4 electric. I am interested in power set up, weight, servos selected for elevator/ rudder in tail. How much weight if any did you add to nose for balance...responses appreciated

While it is not the Pro version I did assemble a AVA-EF about a year ago. Here is the build thread.

Motor: Neu 1110/1.5Y/5.2
ESC: ICE50 Lite
Battery: 3s A123 2300 (Also has a 2s A123 1100 for Rx)

Flaps - HS-85MG
Rudder - HS-5065MG
Elevator - HS-5065MG

With all the battery weight I have up front I have had to add about 1/4 oz to the tail to balance. Total weight is 61 oz and I don't remember what prop I am using but power is ~360 watts and it takes about 20-25 seconds to make it to 200m.

Here is the setup I am using in my AVA 4-Flap:
Motor: Hacker B-40 10L 4.4:1 gearbox
Prop: AeroNaut 16 X 8
ESC: Castle ICE Lite 100
Battery Thunder Power 1800 mah 3S
Rudder, Elevator MKS DS6125
Ailerons HiTec HS-5125
Flaps JR DS 378

Climbs to 200m in about 24-26 seconds.

I had a couple of problems in assembling mine:
1 - The vertical fin did not mate properly with the tailboom; the tailboom was too large in diameter.
2 - The wings did not mate properly with the fuselage; the spacing between the holes in the wings was considerably different than the spacing of the bolt holes in the wing pylon.
3 - The wing saddle mates poorly with the fuselage.

If you order one I would suggest that you carefully check all pieces for proper fit before beginning assembly.

An affordable approach with competitive edge.
MKS 6100 all around, maybe 378's for flaps.
HK 2221/10 - 3000KV
with Micro Edition 5:1 NL from Reisenauer's
CFK 19x8 prop, Reisenauer spinner.
Sunrise 60A ESC ( ) , the only chinese electronics I use. no need for an external BEC.
TP 3S LIPO 1800mAh 65C.

Good to go.
