I and a few other buds of mine have purchased the Tower hobbies KAOS..
we fly them all together have alot of fun... I decided I was going to try to
make this kaos as fast or faster than a quicky 500 pylon racer... but other
than just looking at pics and trying to dig up old threads about those planes
I sure would like to get as much speed as I could out of it .... and learn more
about how to do it... Sure I thought about a tuned pipe... but we have
already agreed NO TUNED PIPES... but other than that I guess I have
already set the bar.. I have installed a NEW OS-55-AX with out installing
a DUB muffler.. ( which I plan on doing ) I have modified the Stock ( old )
style muffler by taking out the baffles... I was told that style muffler is better
for power than the original bulky style. I put the KAOS on a diet already
I ended up taking of the canopy,,, I turned it into a tail dragger,,,with super
light plastic wheels. I am also using a 10x8 apc prop which I had an
aluminum spinner 2 and a quarter,,,, which will be replaced with a much smaller
style like the ones Dub offers. MY plane is fast right now... the others cant keep
up with me its been alot of fun,... so I figure why not take it too another level...
so I have takin the motor back off and reclocked it so that the muffler will be under
the plane just like the Quicky 500 ones.I took off the nose cowling like the quicky,s
I had even thought about installing smaller servos or smaller plus relocating
I really dont need a full size servo for the rudder.. or throttle... any other ideas guys.

I have already made some improvements on the tail section...
I dont plan on pulling like a pylon racer.. but I thought that extra
triangle stock would help improve the strength of the tail.... so far so
good... while we are racing around our field we are taking semi wide
turns... so the smoother you fly the faster your plane stays.

here are the pics of the spinner and muffler Dub offers any one use these on a
OS-55-AX ??

Here is my Kaos.... looking more and more like a Quicky 500 ....
I ended up finding a spinner I think will work nicely....

So now my Kaos has a name.. installed the decals....

Demon Kaos

There is a world of difference between a pattern wing and a speed wing. Just look at that leading edge - it's not designed to cut through air like butter.

WELL of course Cpt Obvious.... I NEVER SAID... it was a Quicky 500 or it will go as fast as one...
if you actually read the thread a group of us have these cheap planes and having fun with them.
I would like mine to be as fast as possible....and just asking for others that have
experience with such planes... ( NOT POINTING OUT ) the differences between the two.

Its a Kaos.... plain and Simple.. Now what things could I change or do by adding to make it go faster ?

aspeed

If you are using the OS muffler you can open up the outlet a couple drill sizes as long as you can keep the needle setting. Or pitch the muffler completely if the field rules allow it. Open up the carb hole and deburr it very well. The throttle will really be only a shutoff. Those wheels are a bit wide. You can buy skinnier ones or take an angle grinder to streamline them while spinning them at the right angle so they don't over rev. Remove a shim (experiment) More pitch on the prop.Typical stuff. A bit here and there, and record the results in case you go too far.

Here are the Dub Wheels.. I placed an order last night.. the muffler and the wheels...
I dont know if running with out a muffler would be such a good idea... it needs pressure
for the tank.... I agree the wheels are wide.. but understand the wheels that came with the plane
were much heavier... so I did make it better but not the best... I went one step more with the
landing gear.. I grinded the leading edge instead of it being blunt I made it appear like a knife
edge... the idea I had was it will cut the air better ... I guess LOL.

I how ever do belong to an extravagant flying field... the field
does not have any sound rules we are in a remote area plus
the other place I fly is on personal property... the gentleman
had his very own 50x800 paved run way.. and its by invite only.

I took your advice.. and I drilled out the muffler pipe exit...
It wasnt easy but I bet its worth while I should find out
tomorrow...

aspeed

You should always get a before and after rpm check. You will get a bit less tank pressure, but if it still runs well in the air, then you can open the carb a bit too. That is until it doesn't work anymore. Then I never said a thing. I always check the open exhaust rpm to for comparison. The Jett muffler should beat that.

It ran really good..... i dont know if it was a noticable faster I agree i should have used a tac to compare RPM,s.... ive still not tac,d it yet i flew it.... lol I installed a 10x9 prop over the 10x8 and the 9 pitch actually slowed the performance down it wasnt as fast as the 10x8.... i thought aboit trimming the ends off making it a 9.5x9..... not sure if that would improve the performance ?? Or trimming the 10x8...to 9.5x8....any thoughts on that idea ?
One thing i noticed since I opened up the muffler exit....
inverted flight was not all that good for the performance of the motor.... i will fly it again and compare... but im wondering if the loss of tank pressure hurt the inverted performance ???

aspeed

It is probably richer inverted if the tank is lower. I wouldn't go any farther with the muffler hole or carb size. Try a bunch of props. Usually square dia/pitch is max. 8-8, 9-9, 10-10. but the rpm has to be right for the power band. The fastest guys just test more than everyone else.

I have no problem testing... lol
i thought about taking my 10x8 prop
cutting the tips to make a 9.5x8 prop
