I am looking into the next project i want to build and I am thinking of either the loaded dice, or loaded dice II. Only problem I am having is figuring out what I want to power it with. I am on a budget so i want to stick with an affordable 2 stroke, however I haven;t been able to locate any with a rear exaust port. So:
- Can I use a side ported engine, and how?
- Is there some place you can recommend where I can buy an affordable engine that is rear ported?
- anyone have any experiances building either plane?
thanks

martup,
I built the LD II from RCM plans this past winter - easy build and a very nice flying plane.
I had the same problem with engine selection - finally decided on an MVVS 91/purple pipe from just engines - this seemed to be the only afordable/available engine in this size, and as a bonus you don't need nitro - makes practice a bit cheaper!
If you decide on a side exhaust, I don't see any easy way to run the pipe under the plane and still look reasonable - I'm sure it could be done, but not easy.

Hi,
if you can get one, the best engines are either the Hanno or the webra 80 rear exhaust. You may be able to pick one up second hand, not sure where you'd look though.
I flew mine with an OS 91fx mounted inverted with a side-to-rear (swan neck) manifold and a bolly pipe. It looked neat, with just the alloy header ducking out and then back in, a bit like many of the YS 140 installations on the big planes! I sent the geometry of the plane and engine installation to just engines and they made a very nice looking custom manifold and it really was a neat installation. Unfortunately the plane met with terra firma a couple of years ago due to a radio problem, or I would send you a picture.
Or, you could try using the standard muffler, I am sure you would have plenty of power. If it was me I'd mount the engine canted over so the exhaust is lined up with the fuz centreline, I'd rather see a cylinder head sticking out than an exhaust!
I would recommend the IIS, it is a later design with a bigger fuz and flies better than the earlier versions although they all fly great. It's a superb plane, one of the best from the early 90s and I would thoroughly recommend it.
