    --> Europa-List message posted by: "R.C.Harrison" <ptag.dev@tiscali.co.uk> Congratulations Charlie. Now you can join us on the Baltics Trip ! Regards Bob Harrison G-PTAG -----Original Message----- From: owner-europa-list-server@matronics.com [mailto:owner-europa-list-server@matronics.com] On Behalf Of Gillian and Charlie Laverty Subject: Re: Europa-List: Removal of bushes --> Europa-List message posted by: "Gillian and Charlie Laverty" <bb@baliscate.freeserve.co.uk> Gillian & Charlie Baliscate House, Tobermory ,Isle of Mull ,PA75 6QA Tel 44(0)1688 302048 Fax 44(0)1688 302666 e-mail bb@baliscate.freeserve.co.uk Just a brief message to all. Charlie has a big smile today, Ivan Shaw performed the first flight of Charlie's Classic (build no.60) mono, G-CLAV. After a few irritating but minor early glitches, (not least the trailer designer obviously thought Europas were gliders, we had to cut slots to get the propeller in!) we loaded up G-CLAV and went gently down the road from Tobermory to Glen Forsa, a beautiful glass strip with a very nice log cabin hotel run by Brendan Walsh, late afternoon Ivan took off and explored the basic flight envelope including stalls and 5000 rpm cruise. Stall was very slow and cruise was pretty fast so we are anxiously looking forward to an oprtunity to callibrate airspeeds. Handling was excellent. Brendan offered us a drink at his bar and quietly produced a bottle of very nice champagne. Magical day for us all, Charlie and his very patient wife Gillian, myself after quite a few years of occasional working hollidays and Ivan, who calmly used his wide experience of test flying to give us a successful fulfilling day. Even the Western Islands weather was beautiful. Graham

    Subject: Monowheel over center?
    --> Europa-List message posted by: "Ronald J. Parigoris" <rparigor@suffolk.lib.ny.us> Assembled undercarriage of XS Monowheel yesterday outside of aeroplane. When gear is down, the LG08s are perhaps 1/32" over center when they contact only 1 spot on the very top of the stop on the UCMF. Curious how much over center those flying have? I can see bad things will happen if too much over center, but my gut feeling is ~ 1/8"?? That would require either cutting through the cap on UCMF, or milling a pocket on the LG08s. Thx. Ron Parigoris A-265 XS Monowheel Juggling battles between instrument module and undercarriage at the moment. Hint for 2+1/4" instruments so you need not fight this battle: If you install a UMA Light Wedge, it pushes instrument back in panel and slight decreases diameter. This nets to an instrument that unless viewed straight on loses most of markings unless you move head to uncomfortable position. Since a Rotax Tach was included in my FWF, I figured I would use a light wedge for it, and figured to be consistent would use a light wedge for MP and Diff Airbox/FP. I sent back MP and Diff for exchange for internal EL, and ordered a internal lit Tach as well. Anyone need a New Rotax Brand Tach? BTW 3+1/8 light wedges on altimeter, Winter ASI and Ilec vario seem to allow fine viewing. Other local guy said he needed to purchase a 3+1/8 DG with markings more towards center to allow use of light wedge.

Several people asked for photos of my installation which I have now found. If anyone would like copies please let me know. It is the one where the servo is installed outside the seat support cavity, directly under the pilots right thigh. Carl Pattinson G-LABS

    Subject: AIRCRAFT CONTROL DURING TAKEOFF
    --> Europa-List message posted by: "ROBERT LINDSAY" <rlindsa2@san.rr.com> I have to share this scary tale with you. It shows what can happen with just the tiniest absence of vigilance. Perhaps it will help you avoid the careless move I made recently. I've been flying for over fifty years with thousands of hours in the air and hundreds in various models of Europa, including a half dozen first flights. While preparing for a solo flight in a tri-gear on a gusty day, I taxied downwind for takeoff on runway 09 at Ramona (KRNM) in San Diego county, California. Winds were about 060/20 kts and with little rudder effectiveness I used the brakes for directional control. After pre takeoff checks (including control movement) I twisted my body around in the cockpit to check for landing traffic. As I did so, my right foot inadvertently came off the right rudder pedal and was then resting against the firewall bulkhead. The tower cleared me for takeoff and an immediate left turn after airborne. As I taxied into takeoff position, I applied what I thought was full right rudder. Not unexpected, considering the wind, right brake was needed to line up and also during steady power increase for takeoff. What was surprising was the rudder did not appear to become effective as I accelerated. Perhaps I was experiencing a directional wind shift or a strong gust. Lots of right brake was required, slowing my acceleration. Slowly approaching unstick speed and not feeling I had control on the ground, I went full throttle (Jabiru 3300 with climb prop) and rotated at minimum controllable airspeed to get into the air where I was sure I could control things. Wow, what a ride! The combination of not using any more right brake, the full power left turning tendency and the strong weather-cocking wind resulted in an exciting immediate heading change of about 45 degrees to port. On the flying edge, I got airborne and passed between the control tower and a hangar, picking up a few flowers on the way. I asked the tower if that left turn after takeoff was immediate enough and also just what are they reading for current wind. They replied it was about 060/20 kts and sensing something was wrong, did I want an immediate landing. I, of course, declined. I first needed to find out what was wrong with the rudder system. While climbing, the ball was out to the right and I was pressing hard on the "right rudder". I checked the left rudder and the ball went further right. In a flash I it all made sense--I had been pushing hard on the firewall beneath my right foot! LESSON LEARNED: Europa rudder pedals are of minimum size which allows us to extend our legs between the pedals for comfort while cruising--a desirable feature--but........ So how will I prevent this from happening again? Easy. When I'm all lined up ready to apply full takeoff power I will quickly pulse the rudder in both directions to ensure proper foot placement. You fly safely! Bob

    Subject: AIRCRAFT CONTROL DURING TAKEOFF
    --> Europa-List message posted by: "R.C.Harrison" <ptag.dev@tiscali.co.uk> Hi! Robert Easily done also is using a foot brake differentially until adequate rudder authority is available .....then wondering WHY THERE's A HUGE DRAG EFFECT and YOU ARE PAST NORMAL ROTATION POINT ON THE TAKE OFF RUN WITH THE ASI SEEMINGLY STUCK ON 40 KTS because you are still on the brake and not the rudder ! IMHO this is the only reason the finger brakes are superior to the foot brakes. However so long as you have your brain engaged and you are able to co-ordinate the use of foot brakes OR Rudder sometimes as a heel and toe effort using both then there's no problem. I need full rudder almost simultaneously as I hit the throttle on departure and if the cross wind is with the "weathercock" effect of engine torque I know I'm going to need some differential brake as well. However it is almost better to fly off with only a right foot and forget the left.

So imho post cure after. > Graham That's a new one on me! Postcuring raises the glass transition temperature...only. At any Tg, if fully cured (like after a couple weeks), adhesion is your basic "tooth adhesion," enhanced by abrasion of the surface, no? At risk of yet another SuperFil thread, I found that removal of that stuff from chrome-shiny metal spatulas was a chore -- adheres tenaciously. But epoxy laminating resin with similarly no abraded surface -- just bend the tool and the stuff pops right off. :-) Reg, Fred F.
