Status: offline 		hey guys........If a person was wanting to go with a BME 115 on this airplane , and wanted to run a set of cannister's , what header and can set up would you use? Just trying to get an idea of how to set it up on this airplane.

also.....Has anyone got much flying time with the BME 115 on any cans? I thought i saw someone in one of these threads showing off a set of CF cans that looked pretty trick.


Thanks Guys!!

Fix is buy a set of KS headers made for a DA 100 (angled) and cut the flange off and weld up a set of BME 110/115 flange and good to go. You can get the flanges from Aircraft Int'l for the BME. The carbon fiber exhaust are actually full length tuned pipes, and would take some work to put them in the sukhoi.

Status: offline 		flyinrazrback is right on, here's the way I did it on the WH Sukhoi still under construction and the canisters are rear exhaust MTW 75H I believe the H is for rear exhaust
Thanks

Status: offline 		Awesome..thanks guys! So if i have this right , i need to buy two sets of header's (one for a DA 100 and a set for the BME 115) , splice the BME exaust brackets off of the BME pipes , and then hook them up to the DA pipes.......is this correct? Also MRT1750....in your pictures , you have your pipes spliced together with what? I see a set of coupler's on there , but what is the other "wrap type stuff"? And will it hold up to vibration well?

Also.....I want to see if i have this right. The BME header's , put the two cans too close together ( as in the sides of the cans are rubbing against each other) is this correct? I guess the angle after it comes off the exaust port is wrong for this plane......is that right? If i had someone who could braze them back together , i wonder if that would hold? Or maybe the coupling idea you have in your pictures is a better way.......more flex and welds won't break.


before i get to carried away here , i am going to write Tom and see if he has this Sukoi in stock , if so , i'm ordering one up within the next few days i think.

Status: offline 		Jeff, you do not need to buy 2 sets of headers, just one pair of DA headers, and the exhaust flange for the BME. The BME flange is around $19 from AI. You just cut the flange off the DA headers, and weld on the flange for the BME and you are done. The BME headers that AI sells do not angle in towards the center of the engine, the DA headers do. With the BME headers, the cans would be too far apart to fit in the plane, so with the angled in DA headers, the space is right as I think the plane was built around a DA 100 and cans setup. The white sections you are seeing is teflon tape wrapped around the flex portion of the headers, it prevents them from leaking.

Don't think that you can't braze the header yourself you can! it's really easy to do if you ever soldered a copper water pipe you can braze a header flange or a complete header. All the parts I needed were purchased from DA they even had the flange for the BME-115/ 110 same flange after cutting off the DA flange I bolted the BME flange to the engine fitted the DA header marked it removed it put it in a vise got a mapp torch from home depot and the silver rod (brazing rod) I used also came from DA. Attached a couple of pictures from the a header I did on a H-9 edge 540 a couple of years ago. In the first picture you can see how bad it looks after brazing the last pictures are after I cleaned it up on a wire wheel.
Thanks

Status: offline 		That looks good after cleaning it up. I understand now why you had them teflon taped. It looks as though you spot brazed them , and then used the tape to seal the cracks where you didn't weld it. I think i'm on the right track now. Thanks man

Status: offline 		You can get a custom made Aluminum header or headers from Karl Mueller pretty quick and inexpensive. If he does't already have your application you just give him the dimensions you want and he'll make them to fit. I think its kgamueller@rogers.com $56.00 for my header, single, probably twice that for you.

Status: offline 		Hmmm.....i never heard of him. I will give that a thought for sure if i end up needing some help. We have Calvin from keleo custom exausts fly out at our feild as well , but most everything he builds is for the smaller nitro power motor's.

Bgold.......i see your from the portland area as well , where do you fly at?

Status: offline 		Ah man...washougal!! I have spent almost 30 years racing MX up at the track.......lotsa good memorie's , lotsa painfull memories.HAHA!!

Anyways........our flying feild is out here in St helens OR , it's called "columbia RC flyer's". It's a great feild , with a ton of really cool guys who fly there. You still have your ordinary group of the old timer's who think your better off putting a tri-cycle gear on everything , and that the new digital servo's are a waste of money......you know the type? I'd have to say about 10 of the guys switched over to flying heli's , but.......who know's how long that's going to last. I guess last weekend , there we're like 6 of them that went into the ground pretty hard..hehe. Don't get me wrong , i feel for them , but they are all getting into it way to fast i think. I'll tell ya , around the end of may when i get up ther with that new WH sukoi , i may be changing some of them back over to planes.
