Gents,
After installing a DLE30 on my plane, took it to the field for first time operation and break in.
I've been using my DL50 for more than a year so by now I know the drill.
Well, back to the DLE30, after choking and not getting a single pop, I decided to test the cables, connection, etc. Everything checks fine.
I tried again unsuccessfully for another few minutes until it was time to remove the plug and check the spark. There was none. I changed plugs. Still no response.
Back at my place I started to think what could I've done wrong to cause the engine not to fire up. The only thing that kept coming was that maybe I connected the regulator (using a Dualsky VR-5L set to 5.8 Volts with a 2s 1000 mahs lipo) and the CDI unit backwards, while doing some trials at the house. I used my voltmeter and checked that the reg was delivering 5.8, constant.
Is it possible to short and burn a DLE CDI unit by inserting the wrong end of the connector? My reg's connector has 2 prongs so it's conceivable that one could stick the wrong side into the CDI end which has room for 3 prongs. Sorry if this question sounds silly but at this point I don't know what to do and would appreciate any feedback.
If you still have the DL50 CDI unit, swap it in and check the sparks. This will rule out battery/switch problems.
Cman_25,
You may need a new fuel tank for gas. Do use a rubber stopper good for gas, and gas-dedicated fuel tubing. If the fuel tubing slides too easily onto the brass tubing, a barb should be soldered on the end (use a small copper wire) to help secure. Since gas is involved, make sure fuel tubing does not touch the engine.
Other than those, the pluming is pretty much the same as for glow fuel.
Personally, I use fuel-dots connecting to the third line in the tank (to fuel and de-fuel).
Thanks, I use the gas conversion kit for the tank, and the gas line and a gas inline fuel filter. I have been using wire to hold the fuel lines on, for years. But now after reading this thread from begining to end I think I may change over to the solder method you talk about and use the small zip ties.
I build and set up planes for other people and I am always looking for the best way to do things to improve what I do.
Also thanks for the que on the fuel dot, I have been thinking about changing all of my Kwik-Fill Fueling Valves and install the fuel dots you are talking about.
Thanks for your time and happy flying.
