Has anyone bought / had any experience with aftermerket heatsinks for the Picco .26.


I have bent the head/heatsink on the Wasp .26 a fair bit and I was looking to invest in a new one.


Thanks,


Chris

Sorry guys, I have been a slack prick.



The head is fantastic. I wasn't going to run the new head on
Sunday cause I didn't want to bang it up, but then I thought - ah what
the hell.



It took a couple of nasty landings, it is scratched, but not bent (to
my surprise). This thing appears tough as nails. The access
to the glow plug and head screws is fantastic. Best of all, it
ran ridiculously cool - under 200F. Need to lean it some more.



After I took it's temp, we didn't believe the reading so we tried the
good old spit test - nothing happened to the spit.... Dan offered to
test it in another fasion but I declined - something to do with nuts
and a sack......



So, admittedly it was quite cool on Sunday, but the verdict at this point is:



BLOODY TOUGH

VERY COOL RUNNING

HIGH BLING FACTOR



Regards,



Chris

Of course out of those the most important is the "High Bling Factor".

Sounds like a great head


Anyone want to order me one

Hey... I thought that you and Husky were the OS order Kings around here.



AUSRC, why do you think this cooling head is any more resistant to damage than the others?

Skidd,


Only thing I can think of is that the standard Wasp/Ofna/Picco head is 6061 Alloy and it has been cast. These are 7075 Alloy and they are CNC Machined so they started life as a solid block of alloy. The quality is quite remarkable (for a head).


I am no metalurgist, but everythng I read tells me that 7075 alloy is exceptionally strong.


I did find this however:


The 6061 series of aluminum is alloyed with magnesium & silicon. However, these are only the majority of alloying elements as other elements are included such as copper, zinc, maganese and titanium. A total of 4% of alloying elements comprise the 6061 specification. The 6061 series is divided into grades or designations that refer to the post temper process. The most common grades are T0, T4, and T6. The grades, processes and strengths are depicted below:

<TD width="13%">Temper</TD>
<TD width="55%">Process </TD>
<TD width="17%">Tensile(PSI)</TD>

<TD width="13%">T0</TD>
<TD width="55%">fully annealed aluminum </TD>
<TD width="17%">18,000 </TD>
<TD width="15%">8,000 </TD></TR>
<TR>
<TD width="13%">T4 </TD>
<TD width="55%">Solution heat treated and naturally aged </TD>
<TD width="17%">35,000</TD>
<TD width="15%">21,000 </TD></TR>
<TR>
<TD width="13%">T6 </TD>
<TD width="55%">Solution heat treated and artificially aged </TD>
<TD width="17%">45,000</TD>
<TD width="15%">40,000 </TD></TR></T></TABLE>


Aluminum is extremely easy to work and machine making frame fabrication painless. Depending on the diameter and wall thickness, aluminum tubing can be easily formed using a standard conduit bender. Since aluminum is relatively soft, it can be filed, drilled and sanded with ease.


Just for conversation, I'll also mention the 7075 series aluminum. This type of aluminum is heavily alloyed with zinc making it incredibly tough and strong. However, this aluminum is very difficult to weld making it's use limited to machined components or glue bonded frames.

Regards,


Chris

Thaks Chris... that's great info, I particularly find this line interesting;

Others on the forum may have already known that... but to me it's another good bit of info to file away in the old brain box.

I'm seriously considering purchasing one of these heads. The quality of
construction, (let alone the huge hole in the middle allowing access
for my clumsy fingers) and the excellent temperature control is hard to
ignore.



Do you think that it would have a negative effects running in a new WASP with a cooler head?



Do you think you'd use one on your RB modd motor Skidd?
