    Subject: Re: Brake reservoirs
    Hi Richard, =C2- I installed the pedal reservoirs on my RV 8 and would recommend them to you. The advantages are an easier installation & a reduction in compexi ty by eliminating feeder tubes,etc. =C2- The only problem I noted was that it is very difficult to service th e reservoirs ( add fluid ) in the 8. I solved this problem by cutting the b aggage compartment floor above the pedals to provide access. The cut runs f ore and aft and bisects the floor. I constructed a lap joint over the cut w ith .032' Al. and rivited same to the starboard section of the floor. The n ew lap joint is attached to the existing floor with 3 screws / nutplates . The starboard floor area is easily removable and provides quick access. =C2- One could argue that you could remove the entire baggage floor to ac cess the area in question. In my installation I have a my Blue Mountain CPU ,with all it's associated wiring , mounted on the port side=C2- and it's a bear to remove. On reflection I would recommend the access as defined ab ove, even if the floor was open, since it is easily removed to access the s ystem.

I suppose the only issues that could arise would relate to where the fi nal placement of the the pedals are in relation to the firewall. They could possibly contact the firewall if the pedals were in the forwardmost positi on and you placed the pedals leaning forward. Not the case on my plane and I'm 6 ft tall. Filling the break lines from the bottom up into the reservoi rs was a little tedious using a mirror to check the levels as the fluid fil led the reservoir and getting all of the bubbles out, but presumably if the system is leak free it will be the last time I do that for a while. I gues s you could also overfill the reservoir to where fluid would spill out when tilted. I guess I'm just trying to think of possible problems you could en counter but actually I had no problems. All in all it wasn't too bad and th ey have been trouble free. I'm glad I did it. It seems a little more elegan t than all of those plastic tubes and connections.=C2-I don't remember wh at I used to seal the threads. It might have been pro-seal or maybe teflon tape. Hope that helps!

If so, I'd love to hear from you with any service experience to support the modification ap proval process we have to go through here in the UK. Do they do the job as intended? Are there any issues with them?

    Subject: Re: Yet another priming question
    Dear Listers ... "For What It's Worth Dept", Two years ago my son zero timed a straight tail Cessna 172 built in 1956. Cessna blew NO paint, on the inside of that critter, when built. The protection Cessna relied on was Alclad. There was NO corrosion on the inside of the empanage, wings or tail feathers. There was a bit of surface corrosion on the cockpit side of the root rib and that was it. The airplane had been owned by a group of United pilots who never hangared the airplane for years. Regards ...

Chet, I used several primers. I sprayed primer on the entire inside of the fuselage using several brands of self-etching primers. I sprayed the fuselage using a spray gun and a gallon of self-etching primer. I used a fresh air ventilator while doing it. Then I primed other parts using rattle can self-etching primers. The SEM worked fine and is readily available. I scuffed first with scotchbrite then cleaned the metal with Dupont 210 cleaner or with MEK. In one case I did not get good adhesion so I stripped the parts and scotchbrited them again and reprimed. The second time held. There is a lot of opinion about whether to prime and how much and what type primer. So, I'm just telling you what I did. We'll know in 35 or 40 years whether or not my efforts were worthwhile. By that time, the internet will have been replaced by mental telepathy - so send me your thoughts at that time. I recommend priming any unprimed parts with self etching primer after cleaning with some type of metal cleaner to remove body oils and other contaminants. You may want to check with the paint shop you plan to use (or a professional painter) to make sure the primer you use is compatible with the planned top coat paint. Good luck and thanks for starting the primer wars again. They're entertaining. Stan Sutterfield www.rv-8a.net Do not archive

    Subject: Re: AeroElectric-List: Adding an antenna to improve on the
    ground reception? Don et all, Ten years ago when I finished my RV8,,I experienced similar problems. After tryiing various different fixes, I finally gave up and got out my wallet and bought a Dorne & Margolin high quality antenna and mounted it on the bottom of my RV8. Well I could not believe the difference in performance both on the ground and in the air. In the air I can transmit and receive more than 100 miles clearly. Also the drag co-efficient is less than 1 knot. Good luck.
