Prop Recommendation for Ehawk 1500

[Sunstorm]

I have a question.

Pls help me attain enlightenment of the rudder

Point aircraft away from you.

Rudder left, both vtail edge face the left
rudder right, both vtail edge face right

I use 9 gm servo for each.

I had ehawk 1400 (just less 100)

25 amps is sufficient, my amp draw only 14.

I use 1000 mah lipo 3 cell.

AR6100e need to do range check for long range thermal soaring. If at Bedok Reservoir it is ok because the slope is not that big.

Rem to program ESC to set brake for props.

rudder right, both vtail edge face right

Very confusing your explaination. Care to elaborate abit more?
For example looking at glider from behind.
Elevator up = left down, right down
Elevator down = left up, right up
Rudder left = ???
Rudder right = ???

Help me fill in the ??? and I should be able to understand. Thanks.

Wrong.

Elevator up = both ruddervators up
Elevator down = both ruddervators down
Rudder left = left down, right up
Rudder right = left up, right down

If you down get these, check that you setup the tranmitter's model mode to V-tail mixing/try reversing the servo functions or swap the servo channels.

This is only basic. Many people claims the V-tails turns poorly using rudder function. If so, check the rigging of the ruddervators throws. Most of the time, the up going ruddervator should have less throws than the down going ruddervators, just like negative differential. Some V-tails turn well with both ruddervators with equal throws.

Joe,
Does that mean the tail is actually working in opposite compared to say a estarter, because the tail is too far back and not using airflow from the wings so the tail got to lift up by up ruddervator instead of down like those common planes?

BUN! Are you flying Heli for too long already?!?!

LOL
Conventional plane like estarter also up elevator control surface when pulling up, doen elevator control surface when diving down.

Elevator up = both ruddervators up

No leh, from this Joe means when I make a dive the ruddervators will all be up.
Normal planes if you make a dive, the elevator will move down mah .... I not confuse so you don't confuse me

You confused lar kekeke.

Elevator up (means pull, confusion must be here lol)= both ruddervators up=Plane pull up

[HotDogBun]

Now I'm confused. Any website to show the movements?

[HotDogBun]

Ok lets do this all over again

Tx ele stick UP =
Tx ele stick DOWN =
Tx rud stick left =
tx rud stick right =

[joe yap]

Bun,

I said elevator up, and since when I mentioned about stick positions? Stop playing old video games. Anyway, nobody has mentioned anything about stick positions in this thread until you did.

[HotDogBun]

What's it got to do with old video games?

Ok, not trying to look unintelligent, but elevator UP means to pull the plane up right? ......

Old video games have reverses elevator stick movements.

Now you got it. Elevator deflects upwards, aircraft nose pitches up.

That I didnt know Anyway I'm not that 'ancient'

Ok got it. But seriously lah, using reference from stick movement still easier to understand for me.
When you say elevator up, I tot you meant elevator at top posn
And I kept thinking why glider so different.....

[joe yap]

I made a quick sketch. Hope you understand. In mode 1 though.

Thanks Joe!
