We used an engine leveler on the engine jack and marked the links on the chains to the mounting ears so that once the engine mount was on the firewall and the fit was good, we could duplicate the engine on/off procedure very easily. Then, as with everything else on this project, when you do and re-do, it's not a big deal. I.e., after all the cowl/prop measuring and fitting, it was easier to remove the engine and replace it with two 5 gal. jugs of water for counter wt. for painting and firewall wiring etc. Once you plan all your firewall forward plumbing and wiring, it is MUCH easier to run your cables to the heater vents, for example, with the engine off. Think about parking brakes, brake resevoir, heat shield, other stuff you might want to rivet on to the firewall. Again, with the ease of temporarily installing the engine, don't think of it as "once it's on, it's on for good". Maybe (hopefully) you've already done your wiring/panel layout and construction, but I did not like the tight fit of the battery cable through the firewall where Van's shows it, and went with the bigger insulated bulkhead connector as in William Curtis's site (http://nerv10.com/wcurtis/90Electrical/EL1h.html). That also gives you cabin side direct access to battery +. I wouldn't even punch that hole in the firewall where the instructions say. And don't forget the diodes across the master, and starter solonoids, as seen in his pictures. I'm sure there's lots more, but that's starters off the top of my head.

Probably want to have the oil cooler mount riveted to the firewall, along with the heater valves installed and sealed (of you want the stainless steel ones, mow is the time to decide!) Also, i'd suggest installing a cooling shroud on the mechanical fuel pump and be sure all the oil line fittings are properly installed on the engine and pointing the correct way. Those are harder to get to after the engine is mounted. -Mike Sent from my iPhone On Apr 8, 2010, at 2:17 PM, Rob Kochman wrote: > Thanks, guys...

Where is the fun in that? Remember, the building, and rebuilding, etc. is where it is at. You are supposed to assemble and disassemble every part on the plane at LEAST 3 times, or you can't have done it right! This flying thingy is just a diversion between projects. I can think of several folks on this list that are repeat offenders, and I even know of one RV-10 builder that also built a couple two place RVs and now is working on his second RV-10....and no, it isn't to assist someone or build and sell, as far as I know. I'm sure if an engine hoist can be borrowed once, it can be borrowed again. Or, Pep Boys, HF, etc often have hoists on sale for around $120....less cost than your first flight.

As to dual electronic.....does it matter whether there is 99% reliability or 99.994% reliability? Do you want to risk that 1% or .006%? Will 2 totally independent electrical systems be 100% reliable? Your choice of what risks you want. Are magnetos 100% reliable? Obviously not or someone would design a cylinder to have a single plug optimally located. Certainly 2 electronic systems are very reliable as long as they both have sufficient electrons to drive the electronics. My question is whether the benefits of a single Plasma III are worth the cost and effort to have 2 different systems. Certainly there is better cruise economy in theory, but no difference at full power. If magneto equipped with Slick Start there should be no difference in starting, so are the cruise benefits worth the trouble and cost?

YMMV, Robin -----Original Message----- From: owner-rv10-list-server@matronics.com [mailto:owner-rv10-list-server@matronics.com] On Behalf Of Jim Berry Sent: Thursday, April 08, 2010 9:17 PM Subject: RV10-List: Re: To Magento - Or Not To Magento I discussed both of these points at length with Allan Barrett when I was ordering my engine. His take was that 9 : 1 pistons gave a modest increase in performance, with no decrease in reliability or TBO. I wanted to do one mag and one electronic ignition. He was not willing to build an engine with electronic ignition for a variety of reasons, but would delete one mag if I wanted to install an electronic myself. He convinced me to go with 2 mags. Allan, chime in if I have misrepresented you position.
