Status: offline 		How much, and did it come with a pipe?  I have 3 Ucktam .15's.  Two piped ones, one wore out the piston/cyl. trying to start it, and the other one seems to run good. They both spit a lot out of the front bearing.  I haven't got it on the pipe yet, but am sure it will be good.  I also got a combat style .15 that is a copy of the Rossi.  It runs real good.  Only 500 rpm less than a real Rossi with the one piece plug. It doesn't spit out the front.  They all have problems with screws.  I replaced them all and re tapped the holes.  I realised then why they are a problem.  There is sand pieces in the castings, which ruins the taps and makes the screws tight......  Overall I am ok with them because two came with a pipe for $50 each, but the one piped one is likely scrap.  Maybe I will try to heat treat it as was mentioned previously.  I like my AP .09 better than the Uckams. Same deal(cheap) and better quality and designed for planes. Rear exh. too so the Ucktam pipe may work.  You will have an adventure with yours I am sure.  It will be OK if you spend enough time on it.

Status: offline 		Many of these engines are set up for car use and have the prop and exhaust on the same end.

If so, check the bypass porting and make sure there is a port if you reverse the front and rear housings.

Most of the front housings are steel but they do have a lighter aluminum housing available.

The crankshaft thread is very short so you will need a shouldered type prop nut or spinner to get enough depth for a prop.

Here is one of my engines with a prop spinner nut made for me by Arne Hende.

I have three of these engines and have yet to try running one. Too busy with horses these days.

The screws are only slightly harder than butter so I need to replsce them with the socket head type.

Status: online 		I didnt get it yet so I dont think it comes with the pipe. If so I'll be happy. I figured it would be a winter project and I have a serious RIRE thing. I want one so bad and the decent RIRE .15s are too hard to come by for something im willing to pay.

Dan, any idea where one would find the aluminum front end? that could be a nice bit to have.

So the list goes:
-Change screws
-check porting
-check fit

Status: offline 		No, I don't know who would have an aluminum front housing but Ed Carlson imported some of them so he may know.

I have one but don't want to give it up, also have a pipe. The aluminum front housing is also black, and looks just like the steel one but a bit lighter.

Status: offline 		I read somewhere (I read too much) that a front intake/front exhaust may run better because of the prop blast cooling the hot half of the motor.  Of course that would be without a muffler.  It could be better clearing of the exhaust gases as well.  It wouldn't matter on a boat. If you can't find an alum. housing, a bit of whittling on a lathe could remove some weight.

Status: offline 		But beware the distortion effects of assymetric cooling in that case-the liner may well tilt out of vertical. There have been very few successful aircraft model engines that used a front exhaust layout..............the Danish Viking being the only one I can currently think of..............

Status: offline 		It's a pretty small part and I doubt if taking the time to machine an aluminum replacement would be worth the minor weight savings.

All of my engines came in the car setup with exhaust to the front and intake to the rear, so if you have one with the prop on the front with rear intake and exhaust it would be an airplane version and may already have an aluminum housing.

Check it with a magnet.

Status: offline 		G'day there!

I have ordered from Hobby Club recently.

Some mufflers and R/C Carbs for a pair of MVVS 1.5 diesels.

The order took a long time, but was eventually delivered. I would buy from them again.

I have an MVVS .15 RI / RE diesel engine, it is very nice, and an R/C carb can be fitted if desired.

Would love a pipe for it.

Status: online 		got my order today and ran the engine with a 6x4. I need to tap the case for pressure nipple or something, that is the only problem right now, fuel feed. runs fine other wise (maybe its my tank).

20000 and change on the 6x4.

the front end (prop side) is SERIOUSLY heavy. I'll probably try and get someone to make me an aluminum one on a lathe, its a simple looking piece.

heres a bad video, just grabbed my phone from my pocket:

Status: online 		A 24-26 inch span model will give you enough wing area for easy launches and landings with a 6x4 prop. It will also be pretty fast..but not so fast that it makes your eyes bleed...

Status: online 		This is the model that was built for the ASP .12
I think it has 26 inches of span.
Actually, 28 inches would be a good size if you want a plane that is super easy to fly and still give you decent speed with the 6x4 prop.
Just build it similar to the Blink with a minimum of materials...just what it needs for a sturdy perimeter frame and engine mount.
1/8" fiberglass tube spar and spruce or hard balsa leading edges. There aren't many frame members in this design and the most important thing is to build it straight with no twist.
Funny how the 6x4 prop looks kind of big on this plane.
A 5x5 really made it faster, but much more difficult to launch.

Status: online 		Skaliwag, you will have to ask ProBroJoe what's in that glass....I'm not sure what it is. He likes the porters and the stouts quite alot. I brew nothing but IPAs, but did brew a "black IPA" by accident. It tasted like licorice beer with a big hoppy bite..pretty nasty from getting over cooked..... After a year it tasted like 6% ABV Worcestershire sauce.

Status: online 		I think I'm going with what CP said. a 28" delta. If it sucks I always have an ASP .12 I need to finish convincing to run. I figure I should be able to get more RPM out of this UCTKAM with a little work. I didnt do anything but reverse the ends around.

I re-read this thread and I dont get what all the "ports are blocked" hoo ha is about. yeah, its not the smoothest flow from the rotors out to three ports, but nothing is obstructed. With a little dremeling there might even be some nice flow.

As for the leaky front bearing, that might be why I have fuel draw issues. Im thinking a bladder or a pressure tap should fix that. Engine runs great after you choke the intake for a couple seconds to get the fuel flowing.

Ive also got a russian Serogin 6.42x3.67" prop to try...
