One of the problems with having too much elevator is that you are able to harrier the plane and you won't ever see a defined break, but rather a mush. With only 10 to 12, and quite a bit of patience and practice, you will see the break. The real key is being able to see it well enough that you give your rudder (not aileron) input at exactly the same time the break occurs. Then bring in your aileron once the nose is down and rotation starts.

Thank you! That's very helpful to know. I will practice that as soon as I get the CG set.

Watched you video Greg Great looking plane. I will come up to the field next Wednesday if the weather is good. Hope to get some practice in for the farm event. All my planes have about 11 degrees elevator, 40 degree rudder and 20 degrees aileron. sometimes I think 11 on elevator is to much but keep it in for stall. I can not seem to remember to flip a switch. lol. Hope to see ya next week.

Thanks, Joe. Looking forward to flying with you. I'm going to be out there every day, as long as weather is flyable. I need someone to call out the trimming maneuvers for me.

I've got the throws dialed down to 10/18/45 on low rate switch for E.A.R. I'll be out there today for second flight and CG test. I moved the main packs back about 2 cm. I hope that will be enough.

Yes, with 70% expo.

I would suggest no more than 20 for precision and just use 45 for hammers.

Way agree. You will fight that much rudder on low rates for sure. And IF you thumb or fingertips memory 45 degree throw and then IMO learning a type of bad habit.

I'll give that a try, but that's one more switch to throw for the hammerhead. What expo at 20?

I like 30% at 17 1/2 degrees

I hate flipping switches as well so fly the entire sequence, including hammers, on one rate except for rollers. I have a different flight condition for those with a little more rudder and elevator and a lot less aileron.

Thanks.

Just got back from the field. I got someone to call out the maneuvers on the trim chart, so I was able to complete most of them in one flight. CG and lateral balance are spot on! Aileron differential is very close as is, by the third roll it was walking slightly to the right on 45 upline. I need to mix in some up elevator to compensate for slight pitch down in flat rudder turn.

So, for maneuvers other than hammerhead, can you feel the difference between 45 deg rudder throw with 70% expo, and 20 deg with 30%? I take it the answer is a big yes! Maybe I've already got into a bad habit of using very small stick movements, except for those maneuvers that require banging the stops.

Well, I found out the hard way that having a dead zone - no response - for the first quarter of my throttle is very bad. I've been flopping my hammerheads thinking I had some airflow, when in fact the motor was off. I tried to fix it at the field today, but couldn't find the right setting to adjust. Landings have been OK so far, but I could get into trouble there as well.

I had an opportunity to fly this plane in heavy winds today. No surprises, except getting used to the low rate on rudder. Cross wind at altitude was strong, and to keep loops on track I was putting in almost full rudder at the top. When I stopped correcting for wind at the turn for the hammerhead I drifted 20-30 feet down wind away from the runway. Fun times!

clad, always use fixed endpoint on your castle ESCs...and then adjust your throttle channel's throws so it's always exact.

Thanks, DJ! The Castle Link endpoints was the step I was missing. I'll have to do that plus add some idle to a slider switch. That should help my hammerheads. - Greg

I missed practice yesterday Mad so I could finish building and tuning a second plug-n-play battery tray. I finally got that working and adjusted the endpoints on my throttle (thanks, again, DJ!), so motor now starts as soon as I advance the stick. BigGrin Also got an idle adjustment added to the left slider, so I can set idle from 0 to low RPM (didn't get a tach reading) independently of the stick. BigGrin BigGrin Now, just before take off, I'll set the idle, so in flight I'll always have some airflow at no throttle. I'll have to see how that affects downline speed. It's easy to adjust in flight without taking my thumbs off the sticks. Can't wait to try it out today!
