Please help:
I'm putting all the pieces of my RV-6A together for the final time to get
ready for engine start and I just keep running into one frustration after
another. Yesterday I was installing the Vetterman exhaust and had to think
up and make some mods to the tail pipe hangar set up on the right side
because I had put the fat starter wire close by (which created interference
with the original hangar configuration).

Today I finished the exhaust and began the final install of my Airflow
Performance Fuel controller (throttle body). Since I have a tri gear
airplane there are steel tubes that are angled down through this area to
connect to the nose gear leg socket. Since the AFP fuel controller is
physically larger than a carburetor I had to do some real head scratching to
fabricate throttle and mixture cable mounting brackets that didn't interfere
with the gear leg socket tubes. Unfortunately, at the time I didn't have
the exhaust hangars in place or I might have noticed that the intersection
of the hangars at the pipe (where incidentally, I had to make the mods last
night to make them work with the fat starter wire) was smack in the middle
of where the throttle cable passes through!!!

Those of you who have AFP fuel injection fitted to the bottom of the sump
(updraft configuration on a parallel valve Lycoming 320/360 on tri gear RV
and using the AFP bracket that bolts between the fuel controller and sump)
could you take some pictures of your throttle and mixture mounting brackets
and email them to me? Serious frustration has set in, I've made and remade
so many things over the 11 years of this project that my motivation is gone.
I go to the hangar on weekends thinking I'm going to get a lot accomplished
and not much seems to get done even though I always have a tool in my hand
(today was mostly head scratching wondering how I'm going make this work
with the exhaust hangar mod, I have to come up with a new bracket
configuration and right now I'm not seeing any other options, should have
just bought a carburetor). When I got the canopy and windscreen done a
couple months ago I thought it was smooth sailing till first flight. Yet
I'm still having to remake and modify things that I had done months (or even
years) ago. Anyone want to buy a 99% project cheap Sad Any builders
assistance folks want to come to FL and finish this thing Sad( I'm tired of
going to the hangar every night and weekend and still no flying airplane
(meanwhile there's 9/11, TFRs, user fees, $5/gal gas....).

80 % OF THE CONSTRUCTION TAKES 20% OF THE TIME. THE REMAINING 20% IS THE "HOW DO I MAKE THIS CRAP WORK" And takes the remaining 80% of the time to figure out.. While doing fire wall foward work, i know that this sounds like building 101 but for others it should be said, place all big pieces on the engine, assy/ exhaust/ intakes,/airboxes/ oil coolers. next place baffles. next is the control cables, next is hoses. then wire the damn thing. and never cut a cable , hose or wire untill ever thing is in posistion. long is cheap, short is expensive.

That said dont let the frustration get to you. with out a pic of your install i can not help but the guys at afp are great to work with. i have a customers system there right now. i am sure they will be able to help. after all are we are talking about is four brackets /cables and springs. you have built an airplane and after this you will be able to make really big noises with it. good luck. call if you get stuck call 559----270-----7113
