Elevator deflection.
 
I installed both my elevators on my new Hanger 9 Hellcat only to find out that theres deflection in the two, there not even, i know dont even trust a ARF i should've checked my joiner wire before i nstalled the elevators, now how do i get both of them straight and level.[:@]

WK,

I'm not sure it can be safely done if the elevator is attached to the horizontal stab without messing up the HS. I recommend removing the elevator and using two pair of vise grips on the joiner wire only, bend into proper alignment.

Here is what I would do...

Get 4 pieces of 1/8" plywood about 1" square

Place two on top and bottom of each elevator where the joiner is embedded.

Clamp each set in place with clamps or two vise-grips.

Holding by the clamps, twist to straighten the elevators.

Now, drill a tiny hole in each elevator (hide the hole on the bottom) and add THIN CA to the holes to strengthen any damaged wood

Minnflyer's suggestion is probably the easiest.

A (radical) alternative is to cut the wire joiner using a Dremel tool creating independent elevator halves, and installing either (a) a split linkage to a common servo, or (b) using a separate servo for each elevator half. There are advantages and disadvantages to each - and a lot more work, expecially on a covered fuselage.

I'd try Minnflyer's idea first.

before i repair this problem im starting to wonder is it worth it, i mean for a 60 size warbird like the hellcat will 1/8th of deflection matter will it affect it in flight im considering the size of the model[sm=confused.gif]

1/8" will make little if any noticeable difference in flight, but you'll see it every day on the ground (and so will everyone else) [:@]
