Hey Tom, hows your 400 doing ?

I just ran 5 liters through mine, and desided to take a look on the internals. Still on the ground......have not finished the plane yet.
Looks like a battlefield in there, with all the crud, slime, and a few tiny metal particals

My crank pins look alright, and are not damaged, and none of my C-clips have fallen off either

Well, the engine starts, and runs great. Running 5 liters of fuel through it deffinatly has made it run smoother.

My 20/8 prop seems too small. the engine accelereates like a dragster, so i guess it could use some more load.
Im goung to get a 22/10 for my 400 and stearman.

The power from this engine is awesome....way too much for my plane
But thats a good thing i guess, as i can run it at lower rpm, where the engine sounds best.

Im also ordereing the microsense 5 cylinder glow system.
It does idle best with the power on the plugs.......but maybe it will improve when the engine has some more time on it.

Hi Sonny!

Ya know, I get sidetracked on other projects and flit around like a bee from flower to flower, only I go from project to project. I have not gotten going on my radial rebuild since where I left off. In the meantime I have done 4 other engines including a customized Jett 120, and some airplanes and boats and latest a steam engine. I guess I have hobby ADD!

Is that castor oil crud? Or rust in there? [X(]

I just chopped the tip of my thumb off in a propeller accident, so I will not be working on anything for a while. But I do plan to get going on the FS400 radial project again later in this year.

Kmot, I remember PMing you recently about finding a plane...waarbird suitable for the 400,. Well the Jack Devine Bearcat arrived and it is a perfect fit for the radial. I might do a build thread on this.......

hehe....I know exactly what you mean about other projects

Ouch...sorry to hear about your thumb [X(]
There is always a risk when playing with our toys....

The crud is caster and rust.

The first times I ran the 400, It was on 5% nitro, and synth oil.
Now, ages after, and bringing it out of storage, I bet it rusted up inside [:@]

But the 5 liters i have run through it now had 5% nitro, 9% Castor and 9% E.D.L.

But the bearings look fine...as much as I could see, and it still runs great

Good to know Sonny, I would hate to see your fine engine suffer from corrosion.

Ram-bro: You are required to do a build thread on the Bearcat/ASP400 combo!!

Yeah, my thumb. Wasn't an airplane, it was an airboat with a "safety cage" that forces your hand inside in an awkward way.

Just a quick update, I am starting on the FS400 again and will finish overhauling it and rebuilding it.

I just did the color buffing on the center section. I need to order some ball bearings for it. I will start on the crankshaft and connecting rods next.

Kmot, ever consider setting up a business to run and service these engines? I would definietly send mine to you to have it run in and refurbed/upgraded as necessary?

Hi Tom....looking good.


I just ordered the Gilmore racer for my ASP 400
I will never get the stearman flying, because its just too time consuming to transport and assemble at the field.....im too lazy for a bi-plane
The gilmore has a 2 part wing, and the fuselage is shorter.....ideal fit, for my tiny european car

I realy want to fly my radial, so I have to get this simple plane.

The ASP realy sounds great in this video from France
http://www.youtube.com/watch?v=u56HE...eature=related


I have seen 1 german planes snap a wing in flight and crashing when flying realy fast with 50cc 2 stroke
So throttle management, and sensible flying is the key.


The manual:

Hi Sonny,

I love that video of the Gilmore in France! Nice perfect grass to fly from also, a golf course!

OUCH! That crashed plane hurts! Everything in moderation!

I finished one head today. All heads have previously been polished, but just with the cutting compound. So now they need to be color buffed. Taking a tip from all the responses I got about my questions of cleaning up buffing residue, I washed the cylinder head in mineral spirits after color buffing it. I also had to use cotton swabs as well as mechanical means (Xacto) to get every last bit of compound residue out. For the most part, the solvent worked pretty good.

The color buffing really makes the polishing pop out! Makes it look brighter than before.

Here is what a head looks like before cleaning. Compound and buffing wheel fibers get jammed up inside the rocker box as well as in the valve ports, etc.



Here is a head that is color buffed, and then hand polished with Liquid Luster brand metal polish, on the right. And the head on the left for comparison is one of the initial cutting compound buffed heads. Only four left to do.

Todays update: I used Q-tips and mineral spirits to clean the nooks and crannies of the nose section. I finished cleaning it and then hand polished it with Liquid Luster metal polish. And then I installed a new 10x26x8 chrome steel ball bearing I had on hand. I inspected all bearings today, and determined I only need to replace three of them. I have to order a rear main bearing and a caged needle bearing for the master rod.

The nose section turned out pretty good.

Thanks fella's.

I ordered the bearings I needed last night, and in the meantime I will be finish polishing the other heads. Lots more other stuff needed to do as well.

Now that I am in the rebuild mode and focused on this engine it should not be too long before it is back together, barring any unforeseen circumstances.

Just opened up my ASP 400 today [:@][:'(]

And it looks like the Titanic inside..........

My counterweight is growing rusticals.
It must be made of old chinese Lifan motorcycle parts that did not pass QC. [&o]
