    Thanks, I found everything I was looking for in these pictures.

    The key tube work includes, 1. The left front door post which is why the left wing needs removal. In my situation I did the Day & Night left door STC, long ago, which required a new 1 inch door post which surpasses the Trimmer requirement. I called Eddie to find out why only the left tube needed replacing, he said it was the engineers call. 2. The cross member between the front gear attachment needs removed and beefed up. 3. A new cross member between the new rear gear attachment is added.

    This sounds like a fun winter project but, will it really be an improvement?

    If your doing a lot of off airports ops then probably. The cub gear is more stout but also more draggy. That being said, if you covered the gear legs in fabric it might negate that.
    I couldn't tell you performance wise as I've only known the cub gear setup on a pacer.
    My pacer appears to be more stable on the ground than others I've flown, but it has 31's which soak up a tremendous amount of garbage; so hard to tell.

    I figure some extra drag but, my current Pacer gear are not covered. Since the Trimmer STC uses the Maule oleo the actual extra drag should mostly be from the cabane vee. The underside of the fuselage will be a bit smoother. The other down side might be some additional weight. Although, the STC eliminates the bungees and hydosorbs. There is some extra tubing added. I have destroyed Pacer gear once landing on rough surface. Plus, this should be a fun winter project.

    The Husky has a similar gear as the Pacer. There is an STC to install Super Cub gear, cabane and the AOSS suspension system on the Husky. I did this several years ago and even with the gear covered it slowed the Husky down. Don't remember how much, to long ago.

    I talked to my friend Jerry Burr yesterday about this. He said that Wayne M experimented with the cabane vee and found that making a deeper vee made several mph improvement. Jerry speculated that getting the vee out of the slip stream help reduce drag. Have you heard about this? It seems that an easy change like this would be popular.

    Has anyone converted to Trimmer PA18 gear from typical Pacer gear and know the effects of the PA18 gear on cruise?
