RE: ESM P47 Build
hi, I agree, keep this thread going,
they are an excellent model, I have the ESM retracts with a Robart air control, engine is a DLE30, this is a really nice model to fly, for its size it has real presence in the air, with the DLE30 it has heaps of power, big loops, another good thing is this model is nice to land.
the only hassle I have had with mine is the muffler on the DLE30, first off it is noisy, then it keeps coming loose, the noisy bit was reasonably easy to fix, I coated the outside of the muffler in high temp Silastic, with fibre glass wrapping, that made a bit of difference to the noise level, but it still had a real bark, then I found some S Steel mesh, a bit like heavy fly wire, I rolled some of that up and poked it up inside the muffler outlet, only about 1 1/2 turns, just hold it in place with a couple of self tappers, now this did make a difference, this has muffled the sound quite a bit, no more Bark at all, no difference to the RPM,
as to the coming loose bit, it is a common problem, what I have done this time is to throw away the gasket, use a high temp silastic as the gasket, then I bought some long bolts, a couple of big washers, so the bolts are now on the outside of the muffler, lock wired to stop them coming undone, hope this works, I havent flown it since the mod.
the retracts are working like a charm, no problems, just go over the screws and glue them in first, but dont do them up too tight, make sure they are free to cycle. I get at least 5 cycles to a tank of air, my system will hold air for weeks. my air tank is under the wing, so there are no air joiners.
