Yea, I was wondering if that would be the case....

Well now we know. I'm guessing the power difference is slight anyhow. I would like to hear to sound though, could be deeper more grunty.

Who wants Fat cans anyway.. lol

Re: 32.5% Carden Baby Yak - BBT! - Build Thread

Just another quick note on the variety of canisters. As mentioned, short n fat or long n skinny. It should also be noted that both versions can also be ordered in front or rear exhaust. Had the long n skinny ones with front exhaust last year. On the Dalton that I'm just finishing up, I ran into the same issue that Trev has experienced with the front exhaust interfering with the gear mounting plate so I got a set of the long n skinny ones with rear exhaust and stuffed those in without problem. We'll see this year if I notice any performance difference. I don't expect to. Will probably also be able to get a good comparison between the long n skinny vs the short n fat as Tom (who is also building a Dalton) has those in his. We'll see.

Trev, you mentioned some extensions for the stingers.......... what're you planning on using? I haven't even looked for anything yet but, just wondering if you've already got that sorted out.

Builds looking great, btw

Cheers,
Dave

Dave,

We are trying to find some 15mm or 9/16" I.D. silicone tubing but no luck so far. Aerotrend use to make this stuff but even though there website is up I think they are going or have gone out of business.

There website seems to be updated but only to tell you what is not in stock.

If you find any in Ottawa or online please order a piece for me as well.

Dennis D has put me on to some silicone rad hose but I have not found it yet.

Hey there! After all this discussion, I just called DA and had a chat about the different can designs. They said that the power difference is negligable and we would have tough time telling any difference (skinny vs fat & rear exit vs front exit) and that they can`t tell the difference.

They did say that there is a difference with the sound... the long, skinny pipes give more of a racing bike sound (higher pitch, more of a tuned pipe sound) vs the fat ones that have a deeper sound, but that in terms actual noise output, they are the same (just a different tone).

I probably didn`t do that explanation justice, so sorry!!

In terms of the extensions, Jim and I are working on finding some 5/8" inner diameter silicon tubing... I`ll let you know when we find some!

Cheers

Re: 32.5% Carden Baby Yak - BBT! - Build Thread

Hey guys,

I haven't even begun to search, to be honest. That said, if I find something locally I'll buy enough for the both of us and let ya know. I can't imagine it'd be too expensive.

Trev, didn't mean to imply that you hadn't explained the differences well enough.......... I just felt like posting in your thread

I'm not surprised that DA is saying that there's no diff in performance for the different cans. When I was checking them out before the set I got last year, I found that the internal volume is identical between the different versions. Anyway, time will tell.

Cheers,
Dave

Re: 32.5% Carden Baby Yak - BBT! - Build Thread

HMMM Great news!!!


Its amazing when you hear 459032879032 stories from 2394325342987 people....

After Jim telling me about the new DA's power boost I've been so paranoid about making the right decisions on exhaust, oil ratio, wieght.

I should just sell the old version 100 I have and get a new DL111cc

I am excited to see the difference between your new 100L on the same cans and prop as my old version 100.

Andrew

Re: 32.5% Carden Baby Yak - BBT! - Build Thread

Ok, I'm all sanded out! Big night of shaping, sanding, sanding and more sanding Good news is that the bellypan is installed

I love Cardens, but the Yak is an insanely complicated build due to all the sanding (and when the skins are only 1/16" thick, there's no room for error!

Another thought just crossed my mind... how am I ever going to cover this area ????

Re: 32.5% Carden Baby Yak - BBT! - Build Thread

I was all happy that the belly was done and then had to do it all over again with the removable landing gear belly!

I inlaided dowls for the 4-40 screws and the blind nuts are on the inside of the landing gear plate.

The dowls are also recessed, so the 4-40 screw falls right in and out of sight (if you look closely, one of the 4-40 screws is in the dowl).

Now onto the rear cut-outs in the belly for the canister exhaust !!!

Re: 32.5% Carden Baby Yak - BBT! - Build Thread

Yeeehhhhaaaa

The underside is done! Just a bit of spackle here and there and a finish sanding before covering time!

The second set of holes in the belly turned out well and the canisters will exit nicely in the middle of each. Now if we could only find 2 lengths of 2.5" - 3" of 5/8" inner diameter silicon tubing for the extensions!!!

Tomorrow I'll flip it over and start on the top
