<span style="font-family: Comic Sans MS"><span style="font-size: medium">It has come to my attention that <span class="squiggly" title="To see spelling suggestions, click this word" splc="splc" state="new" word="Hobico">Hobico</span> has been shipping <span class="squiggly" title="To see spelling suggestions, click this word" splc="splc" state="new" word="TT">TT</span> 40 Pro engines with 46 crank, piston, sleeve, and heads.

The case says it's a 40 as well as the box but they are not. This might not be a big deal to you unless you are racing in AMA 424 or Club 40 class.

The first tip off is if a quarter will fit between the head and case you may have a 46.

The stroke and bore are about <span class="squiggly" title="To see spelling suggestions, click this word" splc="splc" state="new" word="1mm">1mm</span> larger on the 46.

If you have one please call <span class="squiggly" title="To see spelling suggestions, click this word" splc="splc" state="new" word="Hobico">Hobico</span> and let them know it.

These will likely be engines purchased with in the last year...</span></span>

Here is a letter posted here on RCU under the Club 40 pylon.

Dear Gary,


We are not sure if this email address still works for you, and hope this email can find you well.


I have some questions those are important for all flyers who loves club 40 racing.

May I know how many flyers are still in this race?

So that we can decide to discontinue the <nobr><font color="#f35b00">Thunder Tiger</font></nobr> Pro-40 or develop a brand new one.


Few years ago, Pro-40 was exclusively engine for the race, but now the race has Super Tiger GS-40, too.

As the manufacturer of Pro-40, our responsibility is much less.


Looking for your reply.


Best Regards

Keep the .40 and replace the .46 with a .50. Same case but larger cylinder.
