Shocky Elevator Trim
 

I got my shocky flying... what a blast!!! Torque rollin' inches off the deck, flat spins, and on and on... sweet!!!

One question:

My shockey requires an inordinate amount of up elevator trim. I'm using a 1200 mAh battery pack, which is much too large, but it's all I have right now. CG is 55mm. Axi 2208/34, CC10, 6g servos... it's pretty light other than the battery. Anyone else have this problem? Is it the weight of the battery or an odd thrust angle or aileron rigging etc....?

Pretty sure that will be the cells, how much do they weigh ?

If I remember right, about 45g... the same as a 700 3s pack. Old foggy memory, though.

Hi.

Not sure if this will help in your case, but just the other day I made some adjustments to my Extra330 Shockie, which may apply or help in your case too!.


I'm using 3cell 340mah packs,which weigh around 30 grams, and my plane weighs 9ozs ready to fly with battery.(bit heavy I know)
My balance point turned out at around 45mm back with my initial setup, and I too had a fair amount of up elevator trim dialed in.
So just the other night I relocated my battery 5cm further back. This now makes the plane balance at 65mm back, and now my elevator trim is set at dead neutral, and it also stays in hovers better, and does harries more easily.

One thing to watch for(be careful) if you do adjust the balance that far back is the elevator control in my opinion becomes a bit more sensative than it was with the previous balance point.

Happy flying.

I think that may be the case.... I need to look at my CG again. The elevator doesn't seem terribly responsive, though it's smooth and feels good!!!

The odd thing... mine hovers and harriers well now. I can do torque rolling tail touches and things I wouldn't try with my WH extra. What a blast... this thing is my favorite plane right now!!!

Dazed,
