See : http://www.loop.aero I aim to fly over a hundred passengers to convert them this year (I am nearly half way). However, the RV8 design has some flaws, and talking to RV8 owners in Sweden last weekend at an RV fly-in, some pilots have even gone to the extent of modifying the wing fuselage interface, as well as basic things like pilot ergonomics and undercarriage, no design is perfect. In some areas the RV8 excels in others it is poor. The analysis of my RV8 also pertains to my view of SLA's, they have limitations on pilot weight and load, they are not as fast, but they also have a number of benefits, not least of which is operating costs, which will be an increasingly important factor in years to come (even in the US). The jury has yet to convene on the RV12, but based on looks I don't think I will be head of the queue. You say ... > ........ If you own your own RV in England, that says you're pretty > well off. Your statement that started this discussion hinted at that and > made me cringe because it seemed a bit arrogant. To be fair, I've known > other Englishers who were a tad arrogant, to me. Jim, you are making assumptions here that are way off the mark ... but I like your sense of humour. As to list eligibility, I suggest that pilots that have a broad flying interest in terms of type and geography can bring a different perspective to what would otherwise be a rather uniform RV grin. The sun is finally appearing from behind the clouds and rain and it is time to go and fly.

Before paint moment = 1106 * 77.08 = 85,250.48 After paint moment = 1130 * 79.11 = 89,394.3 A moment change of 4,143.82 for a weight change of 24 lb implies an arm of 172.66" for the added paint.

Sigh. Not surprising. The virtual averages for RV-8's here reinforce what you are saying: http://www.rvproject.com/wab/index.jsp Thanks for pointing it out. -- Larry Bowen Larry@BowenAero.com http://BowenAero.com Kevin Horton wrote: > --> RV-List message posted by: Kevin Horton > > Very strange. > > Before paint moment = 1106 * 77.08 = 85,250.48 > After paint moment = 1130 * 79.11 = 89,394.3 > > A moment change of 4,143.82 for a weight change of 24 lb implies an > arm of 172.66" for the added paint.

I will bes ruined..." Reversing the wires on the ammeter will not ruin it. It will only make the ammeter indicate backwards. A full current ammeter is wired in-line with the main load wire from the battery. All current going into or out of the battery must go through this wire,except the starter motor, which is wired in parallel. The ammeter would be overloaded trying to measure the hundreds of amps of starter current. I have seen some charging circuits that have the ammeter leads connecting to the voltage regulator. This is used so that full current is not going through the ammeter. If this is the case in your RV, the regulator could be at fault. I recommended in an earlier email checking system voltage, with and without engine running. If you were able to do this, how were your readings? I hope the A&P can help you. Let's us know how your problem was solved.

And that won't matter if it's digital or a d'arsonval movement. Does the unit have an internal shunt or external shunt? If the big fat wires go to the gauge it has an internal shunt. If so reverse them. If it's external then reverse the small wires going from the shunt to the gauge. A shunt/gauge wired in the battery to buss line is called an Amp Meter and reads in plus for battery charging, and in minus for battery discharging. In this case the entire system load should be no more than 80% of the generator's continuous rated capacity. The extra 20% is for battery charging. If the shunt gauge is wired into the line between the generator and the buss it is properly called a Load Meter and only reads in the plus for any generator output, and you can have the system total load equal to the max continuous load rating of the generator. This is because you can see what the total output of the generator is using this type of gauge installation including that which is charging the battery. In this discussion "generator" includes alternators, it specifically assumes we are talking about max continuous rated output, which many automotive alternator ratings do not comply with. (Some of you may argue this, but I've tested many automotive alternators on the bench and they often over heat at their rated output eventually, their aircraft cousins don't) And it assumes you wish to be in compliance with the certified standards, which in this case do make a lot of sense even though it is not required. And if one wants to use an amp gauge(reads + & -) for both one can install two shunts and use a DPDT toggle switch to feed either shunt to the one amp gauge(in Load Meter mode it just uses the plus side). I usually leave mine in Load Meter mode, but it is occasionally nice to see what the battery is doing particularly right after start.
