Jett is making blue jett stream mufflers for evolution engines .check it out on horizon hobbies.Its due out late april.59 bucks.it should go good on there 60nx.I am going to ditch a 55ax i have and try this set up.

now this is a very smart move

Took me a minute to find it, so I thought I'd post a link:

AHH yes.... I love colour anodizing.[sm=tongue_smile.gif]

Yep...
hits the market shortly.

Very odd, tho they sell it under the EVO name and yet you can read JETT on the nose casting!

Wll this fit the os 55ax bob?

I have to double check on the muffler bolt spacing. Not sure if it is exactly the same. But I think it is.

Jett muffler for the OS55ax available as always without issue. Its the standard Jett-Stream TT40 muffler.

Ok, Bob So this horizon one is not the same as the TT40???
Its just Horizon uk may get hold of this one and if thats the same as this tt40,which does fit the ax55, I can advoid international shipping charges.
If it isnt the same will jet be providing an addtional tt40 to horizon,later, ?

The Red TT40 is model you need if you buy it from Jett since the engine has 37MM spacing just like the EVO .40-.46NT, and .46-.52NX's, OS .46FX-55AX along with Magnum .46-.52's, TT .40-46's, Tower .46;s, and the list goes on. I am willing to bet that it is identical except for the color as the TT40 since the mounting pattern is the same. My .60NX along with my friends both turn over 15,000 (Not peak Rpm) with the TT40 and a 10-8. Mine is a little stronger turning 15,300, but I did a little clean up work to it. With a 10-7 it was over 16,000, and my buddy went running for cover, since he thought it would grenade. From the reading I am getting, it looks like a poor man's Jett engine for performance. These readings are with about four tanks of fuel through them. Dubb stated to me (a couple months ago) that it would be perfectly sized for the .60NX, since it is used with his .60L, along with the OS .55AX, as long as the spacing was 37mm, which I assured him it was. Buy which everone you can get cheaper, or color you prefer more.

sub 60 dollar power boost, a no fail combo, and superb quality

Most of the added power of a tuned pipe, but without the extra tuning.

Do they make this muffler for the 90 size motors?

Just ask JETT !

i have jett mufflers, nelson mufflers, and lots of mac's products pipes and headers... i tell the ones who refuse to read and thing to buy a jett or a nelson muffler, its less headache, for me to listen to them ***** and whine about why their setup isnt running right etc etc[>:]

Yeahbob, a badly set up (i.e. just bolt 'er on and see what happens) tuned pipe arrangement can easily be far more headache than a tuned muffler, deliver no more top end, have balky midrange and probably eat plugs and/or just give the owner fits. A properly set up pipe system can be a beautiful thing. I have a lot to learn about the whole affair still but I've paid a lot mroe attention to pipe setup since last season (seeing as I fly more of them now than ever) and lo and behold things make a lot more sense these days.

and its fun to get it right and listen to the engine really get up and go, better runs better plug life and better fuel consumption
