 |

Listers,
I am seven hours into the phase one testing and have the same - albeit - slight complaint about the rudder not returning to neutral.
Just a thought;: how about installing a "rudder centering spring" on each side of the - rudder cable only - system back behind the hell hole. I remember that the Piper PA 22 Tripacer had an aileron - rudder interconnect home.earthlink.net/~andy2220/.../sitebuilderfiles/sm_21_and_20.pdf - to coordinate the rudder with the aileron during control wheel movement. Seemed to work well and could be over-ridden if necessary in cross control flight.
I would say that my system friction is not excessive - might be a little high because I really worked to get the nose strut to "fit tightly" in the bearings. WX here in Idaho really prevents daily testing - right now a mini-blizzard in progress. Hope for better WX at the end of the week.
Anyone tried this approach - I could live with the "rudder issue / control feel" if necessary but it is experimental isn't it.
About elevator. Installed the Zenith VG kit per instructions and have no problem in flare - I would say that it might be a little more sensitive at rotation speed as I have to be conscious about pitch attitude B4 I'm ready to fly - as I said I'm only seven hours and ten takeoffs and landings into the program so each flight is a new experience. BTW I did bend the elevator trailing edge to level B4 first flight per Roger at Zenith who also highly recommended the VG's. The trim seems OK for level flight in speed range of 85 to 95 with no problem trimming down to 75 - have the electric trim with Zenith design tab from late model kit. For most flight I just don't use the trim. Haven't tried flaps yet as that is a little farther down the list in my test cards.
Still grinnin!

Congrats on your first 7 hours. Ten takeoffs is just a drop in the bucket. You will find that using flaps are like no other plane you ever flew. Hang on the the Y stick as you deploy flaps as it will try to yank it out of your hand. I understand about the weather as we have similar stuff here in Jackson Hole. My suggestion is to do what you started, take baby steps and gain experience, keep power on all through the landing phase and don't get slow on short final as the 701/801 will drop out of the sky pretty darn fast. IMHO
do not archive

i find the flaps hard to pull on . so the circuits are done at full throttle.1/2 way through the Base and to slow the plane down i drop power to 3200rpm nose up to almost stall then stick forward/dropping nose while pulling flaps (at the same time) takes all the pressure off the flaps and is easy to engage.. not as erratic as it sounds. i do inform any passengers what is about to happen. you are instantly slowed to glide, make turn to final and steer for numbers.
i had rudder problems when i first purchased this plane. found iin some conditions the rudder would search from stop to stop. not a fun ride. found the builder had omitted the bottom rib in the forward part of the rudder. would have to slow plane down and pull hard on the left rudder cable by hand to stop the cycling.
installed proper rib section and everything worked as it should. i also loosened the rudder cables a slight bit and installed springs between the rudders peddles and the cables. this made ground maneuvers easier on me and the rudder and made the rudder less stiff in flight.

If you go to the www.ch701.com site and look for Larry Martin's page you can see where he put built return springs into his rudder pedals.

I installed an after market flap actuator called the Kube Kontrol. It's a little pricey but one my favorite things on my 701. Very easy to install and can actuate flaps with light finger pressure. I've used it for almost 200 hours. Here a picture of it installed:

Michael Heinz (Chris's son and a reseller of the Kube Control) told me that the degree of difficulty on the stock flap actuator was a good thing. If it was hard to put the flaps in you were probably deploying them at too high a speed. He also advised not messing with deploying the flaps during your first 50 hours of flying a 701. On the other hand James's plane is hardly stock 
Here is a link to the specs on the Kube Control:

Hello Ron,
In my humble opinion.
I think there is no problem with the flaps of your 701... I am shure that you are flying too fast for the flaps to be set, just let the speed to bleed to 60 (or 55 in low turbulent wind).
I use the flaps because of my strip at 5,000 ft ASL , but in a "normal" landings there is no need to aply the flaps, well probably using flaps might save tires and brakes 
Hope this helps
