Firewall Forward Kit
 
For those that have bought the 14 firewall forward kit from Vans.....

What was missing, what was not really needed?
Is the alternator supplied adequate?
I want a fuse link on the alternator for the B-lead is that there?

Other lessons learned?

The alternator is a 60 amp internally regulated Plane Power. More than adequate. You will need to add your own 70amp alternator output breaker. The single PC-680 battery is not, in my opinion, adequate for an IFR install.

Check with Vetterman's to see if you want his exhaust or the Fire Wall Forward provided exhaust. The one RV-14 I helped with got the exhaust from Vertterman's.

No fuse link provided in my kit that I recall. Purchased mine from B & C. If you happen to be installing throttle quadrant , you could delete the supplied control cable as they will be too short.

Yep - forgot to say that if you plan on the standard push/pull cables the firewall forward kit provided throttle cable will be ~2" short. The mixture and prop fit. Unfortunately Van's does not have a longer throttle cable to substitute so you will need to buy elsewhere (and they are amazingly expensive).

Van's doesn't have a longer one because the one supplied in the FWF kit should work (I don't know why yours didn't, but I have a guess).

Both of the prototypes, and Mitchs' demonstrator were all built using the same controls as are supplied in the kit

I've enjoyed reading AeroElectric Connection, and it makes me think about the firewall forward electrical. The stock RV14 has a fuse block. Is that in the finishing kit or the firewall forward?

I'm changing thread gears, but....
- anyone have a backup alternator on the accessory drive of the IO-390?
- anyone have a battery always-hot bus? What is on it? Why?
- anyone have an endurance bus? How much of the G3X can be on that?

I'm about halfway through the fuselage and I know this is right around the corner....

The fuse block is not included from Van's, I do believe it's available from Stein's. I have one circuit live all the time and it's for one Lightspeed Plasma ignition.

I just installed the prop, alt air, throttle and mixture cables last night- no problem.

Sorry guys, my previous post was wrong! The throttle cable fit fine until...I installed the metal heat tube manifold. The throttle cable is to short and rubs against the bottom of the scat tubing pushing it up against the engine. The design is very tight between the engine, scat tube and throttle cable. I wonder how the flying RV14's keep from chaffing the heater scat tube between the engine and throttle cable?

If you look from the lower right side in the 360 degree view of N214VA available on Van's web site
http://www.vansaircraft.com/images/R...60/RV-14A.html
you can see that the control cable clears the SCAT hose.
