Need help with a DLE35

[Cosmith]

Yes I'm using a Nimh pack, 5 cell, for ignition. Is it save to put a Y on my life pack to power both Rx and ignition? Or am I asking for problems? I do have a extra Life pack but will a DLE ignition take 6.6 volts?

If you want to use one battery for ignition and Rx get yourself a Tech-Aero Ultra IBEC. It will allow you to safely share power, send the correct voltage to your ignition and will also be your kill switch. They are a great little unit, did lots of research before I got mine and nobody seems to have any issues with them. http://www.thunderboltrc.com/index.p...oducts_id=1035 OR http://www.tech-aero.net/ultra-ibec

I only have one gas airplane and I've only been into this hobby for a bit over a year. But, just from a common sense perspective I have to think that something heat related is happening with your engine if it is always fine for the first 5 minutes. I almost wonder if something is happening in your carb or reed block as it warms up and all the pieces expand. It sort of adds up because your engine proper is going to be at full operating temperature well before 5 minutes but your carb and reed block are going to gradually absorb heat from the engine. It doesn't seem uncommon with the cheap chinese carbs to have little problems like this that keep you chasing your tail until you change the carb altogether. One option, just change the carb out for a genuine Walbro...I'm sure the one for the EME 35 would work fine: http://www.pro-rc.ca/walbro-carb-for...ceted_search=0

Good Luck!

PS. Your 5 cell Nimh battery is putting out over 6.6v when it is fully charged anyway. That's just another advantage to Life batteries, you're going to get really close to 6.6v from full charged to nearly dead. I'm using Life batteries with 6v servos in a few applications without a problem.
