</div><div>Hi guys,</div><div>
</div><div>I been operating a DEL 55 which worked fine for a while (probably about 10 - 12 flights) but I have seen problems with ignition and reliability lately. It has stopped a couple of times on the air. I have closed both H and I carburetor vales because it was running a bit rich and moved the timing and it is running smooth like never before but I has stopped again in the air. I'm not sure if the ignition if working fine. I'm using a 6 V 2,400 mA battery.</div><div>
</div><div>Please let me know any thoughts.</div><div>
</div><div>Thanks,...Alan</div>
