Thread: What cars type and model do the aged flyers use to transport their models
06/04/2008 10:15:00

I like driving almost as much as flying so have just collected my new Alfa Romeo 159 sportwagon. Can get P47 thunderbolt, Spitfire and extra 330L in at a squeeze but it takes a little time to interlock tailplanes and wings !

you are both right, i am a big fan of making fittings myself and it saves soo much cash. I always tear apart old electrical goods, esp cd players etc. The small steel or brass drive wheels are well engineered (brass cross haired wheels make small ww1 gunsights) small screws for discreet  hatch and canopy  fittings and jack plugs are great remote electrical connections.I have just priced up a remote glow start connection at £9.50 and after checking through my parts bin have found a 3mm jack plug and socket which is now flush fitted to underside of cowling to make an extremely neat and hidden glow start.  (£10 saved and put towards a Petes Pilot for the office ! ).  Microswitchs are always useful and leds and small bulbs for lamps. I know these things are only a pound or two for a pack but you add up the  packs of screws or fittings in your average build and you will be shocked how much they come to. when accused of being a skinflint i just give them the 'recycling' bit

Thread: 4-stroke exhaust length
18/03/2008 20:35:00

Eric,

thanks for the advice. I will probably make up an extension pipe to match the manifold and monitor engine performance/temp. Is the expansion chamber required or can the exhaust terminate with a slash cut to give a larger exit area for the gas\flow. I thought a straight pipe with no silencer would reduce back pressure and increase power ?

 Hi all,

my first ever venture into a forum, only been on the net for a week !

My latest project is an SE5a and a 52' 4 stroke sits nicely at the noisy end, but i am considering a scale exhaust running down the outside of the cowling terminating below the cockpit . Would this cause issues with engine running ?. it would be approx 12" or 30cm in length without a muffler. Aside from a noise increase( which isn't much compared to the jet jocks at the field! ) will the length cause any running faults due to back pressure ?

all comments gratefully received
