RC Posted April 30, 2008 Share Posted April 30, 2008 I have a brand new out of the box SC46 and have twice had the same failure on this engine. The small length of fuel line between the needle valve and the carb has cut through on the nipple as the pipe comes off of the needle valve.The first instance caused a Deadstick landing on the models maiden flight, the second happened after about 10 min's of taxying set ups on the ground (sorting nose wheel).I have replaced the fuel tube with a thicker walled piece than the original and carefully filed the square edge of the needle valve nipple as this may have been cutting through from the inside but I am still not confident and do not want another Deadstick. Has anyone else come across this problem ? Does anyone have any suggestions ? Quote Link to comment Share on other sites More sharing options...

RC Posted April 30, 2008 Author Share Posted April 30, 2008 I thought the same, the second piece to fail was longer than the first. Quote Link to comment Share on other sites More sharing options...
Redmorph Posted June 3, 2008 Share Posted June 3, 2008 Try running a bit of fine 'wet n dry' around the back edge of the nipple barbs to make sure there is no nasty edges. Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted June 4, 2008 Share Posted June 4, 2008 thoroughly cleaning the job after with neat fuel, ensuring NONE gets inside the tube before fitting the fuel line back on ! Quote Link to comment Share on other sites More sharing options...

RC Posted June 4, 2008 Author Share Posted June 4, 2008 Needle file on the sharp edge, surgical spirit to clean and thicker walled tube has cured the problem.Cheers all. Quote Link to comment Share on other sites More sharing options...
