Rowland I put it inside the intake of the Rotax cylinder cooling baffle. It works fine in flight but not on the ground where it is greatly influenced by the engine temperature. BTW this shows that the Rotax cooling baffle is not effective at all for cylinder cooling while on the ground. Regards Remi ________________________________ Message 2 _____________________________________ Time: 12:12:08 AM PST US From: "nigel_graham@m-tecque.co.uk" Subject: Re: Europa-List: Mod 76 - Altitude Hold Autopilot Hello Rob, I recently had to strip out and refit the CS10 and had to face the same problem so know exactly what you are up against. There is a solution. Ideally you need a trusty assistant - though I did succeed by myself (it took a whole afternoon though :-( ) I used a long socket, and filled it with spare nuts such that it prevented the nut you are attempting to tighten - sliding down into the barrel of the socket. I magnetised the socket by stroking it a few times with a strong magnet - that ensured that the nut would not drop out. Now the nut can be held precisely. The next bit seems non-intuitive, but tighten the bolt (not the nut) from the other side of the aircraft using your assistant and a long socket drive extension. All you need to focus on is keeping the nut in place (a long socket is easier to hold) until the thread catches. The only other thing to consider is keeping the washers in place until the bolt is inserted - this was done by sticking the washers using a blob of grease. It is possible to achieve without resorting to an angle grinder!

Nigel, Yes I have a 914' but I am talking about the space fed directly from a NACA inlet which gathers the air before it enters the turbo. Like all the cowling inlets it will be pressurised by the slipstream/propwash No doubt post turbo the temperature will be higher still - which is why 914s don't need carb icing protection.

Ahh! wrong plenum. That makes more sense as I would expect induction air downstream of the turbo to be in the high 70's C. Thanks for the clarification.

If you were to use 1/4" socket with lots of extensions and universal/s could you get to the bolt? If not how about using a short, medium or long box wrench? If not, then buy a cheap box wrench, cut, heat up and bend if needed and weld on an extension, or use a box wrench you have and bend up a metal bar and use hose clamps to hold it? Since you are in there, get some inspection lacquer and mark the jam nut for the ball fitting.

David Joyce ________________________________ Message 8 _____________________________________ Time: 08:48:57 AM PST US From: "Rob Housman" Subject: RE: Europa-List: Mod 76 - Altitude Hold Autopilot Nigel: What you describe is almost exactly how I connected the port and starboard pitch push rods to CS10/2, the only difference being that I did not need to magnetize the socket. Both of these connections are relatively easy to reach but that @#$%^&* third horn on CS10/2 is (so far) not within my reach with either fingers or tools. Ron: My problem is access. My combination of universal joints, extensions and sockets will not clear the obstructions which include the support bracket holding CS10/2 and the aileron bell crank where it mounts to the end of CS05 torque tube. In other words, I cannot manage to get the tools to align coaxially with the bolt even if I could get the nut onto the bolt manually, which I can't. Next up: Unless someone presents a simpler solution, I'll remove CS10/2 and attach only the rod end to it and then after CS10/2 is reinstalled, attempt to thread the servo push rod onto the rod end already in place. Only if this fails will I resort to cutting another access port in the bottom of the fuselage. Incidentally, prior to installing CS10/2 I used 5 minute epoxy to hold all of those washers in place and used a greased pin slightly smaller than the size of the bolt holes to maintain alignment during cure. With my many attempts to assemble the rod end to CS10/2 these washers have remained in place.

HINT: A no-sanding method to take up the space between the bellcranks: I don't know if anyone has done this, but I found a pretty slick method to take up the clearance when gluing the 'tuffy' spacer between the bellcranks. Get three 1/16" (or so) strips of double sided foamy tape. The squishy stuff, not the normal double sided tape. Arts and craft store ought to have them. Place the strips full length on each of the long sides of the tufnol, and one in the middle. Carefully place the glue between the strips of tape (not too much), and tenderly press the tufnol spacer into the correct position on the bellcrank. The tape will hold it firm in place so it won't wander around. Assemble the bellcranks together as they would be in normal operation, with all of them bolted onto their swivels. Be sure the aileron weight is unloaded off of the bellcranks (I disconnected mine), so that the mating surfaces are not torqued. You want the surfaces to stay parallel to each other and symmetrical forces all the way along the foam. ..The squishy foam tape acts as a spring to take up the exact gap needed for a zero clearance fit. It also contains the glue between the foam channels so one can avoid using plastic sheeting, which might mess up the gap. The glue will squidge out from the top and bottom a bit though, but it can be carefully wiped away with a q-tip or the like. The foam is sacrificial, and will become a permanent fixture in the plane. Bobs your Uncle! Cheers, Greg Hello everyone I have been trying to bond the piece of Tufnall to the fuselage aerolon quick connect bellcrank. Problem is that the redux simply flows out the bottom of the joint. It is too runny! The build manual describes assembling the wings and letting the bond set in order to achieve a perfect fit. I am sure this problem must have been surmounted by all the builders and it has probably been discussed before. A link to the answer would be appreciated.
