Those nuts are medium heat self-locking. Jay in Dallas "Ianrat" wrote: > >Just about to fit the engine mount to the fire wall.

I don't remember having much play in any of the holes, but when you put it all together and add up all the little play in each moving part (including the hinge) it all adds up to a little wiggle. There's a good lesson or three in this that I tell everyone building - > 1. Drill a test hole in a scrap part and try it first, > 2. Cut all panels a little large and test fit first (for plans builders) and > 3. Do a test bend on the brake on a scrap piece before making the final bend on a large part. > > One note about the trim tab since I was flying yesterday and noticed this again. It is hard to trim out for level flight with a quick touch of the button. It is just that sensitive and maybe it moves too fast. If there were a way to slow it down I'd probably try it. I use the standard RAC servo called out on the plans. > > My elevator tab is the large version that I re-made after seeing one at Sun-n Fun. > First one: http://www.cooknwithgas.com/3_23_03_Trimtab.jpg > Secone try: http://www.cooknwithgas.com/5_8_05_Trim.jpg > > It works well and I wouldn't recommend flying without the elevator trim.

Castle nuts AN310 or Nyloc nuts depend on whether engine heat is going to be a factor. Nylocs are only good to 250-degrees F. If its an air cooled engine the engine castle nut is recommended.

Piano hinges were not even thought of when I completed my wings. I'm not sure why they are so popular - You don't get all the gawks and head scratching at a fly-in if you you have piano hinges on your ailerons. I find the yoke easy to move in flight even though pitch is more sensitive. Now if I can just figure out how to make my rudder control lighter in flight. I don't need much rudder input when turning but for cross-wind landing it would be nice if it weren't so hard to turn the rudder. I'm going to take a serious look at it the next time I go out to the hangar.

Is there enough left that you could just use more of the travel in the pedals with a wider rudder horn for a little more leverage via the spare travel left in the pedals? As far as switching to hingeless ailerons using the hinged aileron configuration, do you think that's doable by just riveting in a 100mm wide piece of .016 to act as the hinge I already have installed on my ailerons, or do you think it would just be better to make a new set of hingeless ailerons? The hinge on the hingeless aileron is just the .016 skin, correct? I'm thinking maybe just using the hinged aileron with a skin in between the skins in the aileron grabbing 3 rivets on the top of the aileron would be sufficient. How many rivets does it catch on the wing, just the rivets along the rear spar? cookwithgas wrote: > Andy: > > I have the stock, hingless ailerons.

Graziano" Subject: Zenith601-List: Re: Engine mount bolts Just my $ .02 My Jab FWF came with cad plated steel self-locking AN ???(not Nylock) type nuts. I used these nuts vice the "nylock type" ones supplied by Zenith. I don't have the number in front of me, but you can probably get it from the Jab USA website for the Zodiac FWF kit. In my opinion, I would not recommend castle nuts with cotter keys to lock these nuts as I believe you should keep them torqued or risk fatigue/fretting, leading to possible bolt failure.. Part of my annual Inspection, and every time my fwd skin is removed, is to check the torque. I use 300 in-lbs.

I would just re-make the ailerons. You are a pro at building parts now anyway right? Scott.
