Hay Blazer1,
I have the Ultra Stick .40...with a K&B .61 Twister in the nose. I use Airtronics standard 94102's and I've no problems so far. The model is over four years old, and still going strong. These servo's I'm using do not have bearings.

I beefed up my landing gear support, by adding a 3/8th. piece of good aircraft ply to the inside floor of the model, installed my servo's for the rudder and elevator in the rear outside of my model, and added more supports to my fire wall. I then coated every thing from my fire wall rear, on the inside, to the aft wing hold down area...50/50 2hr. epoxy and denatured alcohol, for fuel proofing. I also added brass tubing to my wing hold down dowls, because my wood dowls began to wear, and gave me a loose fit for my wing/fuse hold down issue.

I had a four servo wing for a while, but then...ended up going to a two servo wing in the end. The model is a blast to fly. I also added a different tail wheel assy. to my model.

Soft landings always,
