General: All is fine except the HXT-900's on the tail... you'll strip them. Go with some 18g servos back there, like HS-81's.

hey TexasFlyer
thank you for your compliment!. the colour scheme is my favourite so far, 1st time painting on elapor and i can say that elapor is great for painting!Normal spray can be used by applying thin coat of several layer.

I flew at the field located at Woodlands Drive 17, it has several field but there's an heli base nearby, have to be more careful when the helis are approaching.

Hi Witterings, the blipping of throttle does help in harrier. i'm still trying to get use to it as i always over blip resulting the plane going into a hover

Servos
I have several HXT 900 9gram servos on hand, can I get away with using those all around? I've seen posts where people are using those on the ailerons, but haven't seen any reports of how/if they work on the rudder and tail. If these would be inadequate for the tail, is there a good no-name alternative to the Hitec HS-85?

Batteries
I also have several loong max / Zippy 3S 2250 20C lipos on hand, so the rest of the powertrain would have to take this into consideration.

Motor
It looks like the Turnigy 35-42D 1000kv motor is the most popular budget motor, any others I should consider?

ESC
Would a Turnigy 40A ESC be sufficient, or should I spring for the 60A ESC for extra "headroom"?

RX
Lastly, can I get away with a Spektrum AR6100 RX?
Hi there,my reccommendation:
Servo: HXT900 on ailerons is good, you need stronger servos on tail

Batt: 3s2200 is adequate, sometimes i use 1800 for 6min flying

Motor: Turnigy TR42-40B 900kv. this motor mounting fits the AM mount perfectly. I'm running 12x6 prop with this motor and i enjoy it.

ESC: any decent 40A will be enough. my motor draws 30A peak and i'm using the supersimple 50A from UH

RX: the AR6100 is definitely a good choice

hope this helps! =)

Yes it does, thanks! which makes for cleaner/easier wire routing, the AR6100 or AR6100e?

Looks real good DG40. I'm sure your maiden will prove to be just as good. I recommend first flight on the low sport rate recommendations. Mine was far to sensitive for my liking at the higher rates.

Wheel trouble

Anyone have trouble with their wheels??? I droped mine in from 1 foot and one of the wheels broke apart. The tread broke down to the hub. I glued it back together with CA but it broke again. Now trying to fit some lite weight DuBro 2 1/4 inch wheels to the bird.

Great Paint job DG, any info on how you did it??

No wheel problems on mine. I replaced them with light-weight regular (Dubro I think) wheels with plastic hubs before I even broke ground the first time. I had to push out the brass insert from the stock wheels and install them in the replacement wheels to fit the axle properly. Personally, I think the stock wheels are neat in idea, but lacking in functionality.

That's exactly what I did as well...never even used the stock wheels.

The stock wheels do work but only have a limited life. I fly mine from a paved strip (Military taxiway) and one of the wheels finally disintegrated. I glued temporarily, but intended to replace anyway.

Wheels

When I first started flying on grass, I tried many, many wheels. After posting a question elsewhere on RC Groups, I found that MPI (Maxx Products International) wheels are the best. I use 3 inch EPW300's on the Acromaster but found that the 2.5 inch EPW250's work well on other comparably sized planes. The latter is VERY light weight at 1.27 oz for the pair. Taxiing, take-offs, and landings are no issues anymore, though I still need to land with some power to keep from nosing over when the grass is really thick.

Winglet to help harrier stability?

I don't really know what they're called, but they look like a vertical stabilizer on the wings. An example would be the Enticement F3P from E-flite. http://www.horizonhobby.com/Products...ProdID=EFL1175 (I'm not talking about the speed brakes with a hole in it) If I glue some deprons on to the wings like on the F3P, would it help take out the wing rocking during harrier? I tired dialing in spoilerons, it didn't help that much, bliping the throttle made it worse for me.

I have been using those wheels for months and they work great on my ACRO.
