I have finished installing the Smoke-System Helper. First off thanks to Craig Taylor and Marvin Holmsley for their help. The install was straight forward, not difficult, and no surprises but it does take a little time. Actually just the kind of project I enjoy at this time of year.
I have often wanted a smoke system but several things always kept me from installing one.
1) I didnít want to give up baggage space.
2) My CG is already aft due to the WW prop.
3) I wanted to be able to remove the system quickly and easily.
4) I didnít want to pay big bucks for the oil.
5) I didnít want lots of oil on the belly.
6) If I wanted to get rid of the system I didnít want to permanently scar the plane.
Marvin and his Smoke-System Helper provided everything I needed to eliminate or reduce my objections to an acceptable level. Here is how I did it.
1)Marvinís tank takes up very little space in baggage area.
2)The CG moves aft only a little (see details below)
3)The tank takes 2 minutes to remove and the pump another 30 seconds. With quick disconnect fittings on the tank and pump along with 1 spacer instead of 4 washers on each side and latch pins instead of nuts on the mounting bolts.
4)Marvin recommends used ATF which I have available to me.
5)With 2 nozzles mounted forward on cyl # 1 & 3 I am hopeful that the mess should be reduced.
6)Installation was done so that the entire system can be removed with no unsightly blemishes.
With the system installed but no oil my empty CG went from 80.94 to 81.25 and 82.19 with full oil.
My normal flight condition with Pilot, Passenger and Full Fuel went from 84.80 to 85.45.
Obviously adding baggage and burning off fuel moves CG aft but it is all manageable within my comfort range.
I made a simple sight gauge for the side of the tank which I am very happy with. The only thing I have left to do is paint the tank and the project will be complete.
