Default Danville flash unit, battery needed

In my last minute rush to get my stuff ready for the last Danville trip. Does anyone have a spare HL style flash unit and or a nimh battery for a spektrum dx7s? I got new batteries for tank but couldn't find one for the receiver locally and I suspect it wont last long in use. My flash unit fried itself last time I was down there as well.

Would be willing to compensate of course, just would be happy to grab it when I got there if so.

Thanks!

Side note for the flash unit - reading my old TK22 manual I saw it has a port for an LED flash instead of the big old bulb + capacitor board setup. Is that literally just for a single LED on a wire like an emitter? Does it work sufficiently well to consider rigging that up instead of a flash unit?

While my stuff won't be any level of refined/finish as usual, will be great to see everyone again.

Yes most of the LED flashes with clark and Henglong and such work quite well and bright though may not be as bright as the high intensity flash unit. But you can use a clear orange LED which looks nice.

Do you need a special LED or anything? I got a few small ones lying around.

Otherwise might go hunting for a parts store. They don't need a resistor soldered onto the LED as well do they?

It depends on the LED. If it's a five volt LED then you should not need a resistor but if it's a three volt you probably will. There's a chart online that tells you what ohm resistor to use with what voltage LED but I'm pretty sure it's usually around 90 to 100 ohms for a 3 volt LED with 5 volts out of the board. One way to check is to use a multimeter and check the voltage coming out of the board at the LED port.

Hope that helps.
