All of the ignition reg that i use are fixed at 5.1 volts less than a fully charged 4.8!!!

Speaking of that, I just charged my 4.8v to take it out to test it today and it read 6.0v fully charged. Right now I have a 6.0v pack charging just for maintenance and it's almost done at 7.7V! I know DA says it's okay for a 6.0v so you'd think the A123's would be okay seem so they're supposed to be running at 6.6v.

Oh well, we'll see today. The only differance is an extra oz of weight between the packs and the obvious slow charge of the nimh which I hate so a reg will be bought if this is the answer. Yes I already got spoiled by the A123s.

Was wondering where you got your reg? I saw one from TBM that sounds similar to your's. Some of the Fromeco regs are around $60 and that's a bit out of my budget. If I can't find a good cheap reg, may just stick to what I have as 2000mah should be enough flying time for my hands to get tired.

Wrapped some more teflon tape for a tighter fit on the canister. Yeah, still rotating a little but no leaks. My header is nice and tight without much tape, but the canister inlet has a diamond plate style friction section on it that I think is doing the opposite of what was intended with the slippery silicone. If the tape won't do it, time to break out the screws.

My cowl has taken a beating and now it is so oily I'm having trouble getting CA glue to stick with accelerator. May clean it again with alcohol and use epoxy. I did cut the mount ring so I wouldn't have to rotate the can and used some screws to hold it as the lower blind nuts are really hard to reach. Everything is okay there now, but if the cowl won't stay glued I may have to order up another one. Than I'll just move the canister back ahead of the gear like you did.

Anyone know how much a cowl should run from WH? Until mine is fixed I'm flying with no cowl. I know, what a way to treat a good lookin plane. I do like the airbrake effect on landing. Almost like flaperons.

Same thing with the 4.8V pack. I've tried unplugging all servos from the receiver except the throttle and same result. Must be time to send my ignition in.

4.8 to 6v is acceptable on DA ignitions. The glitch you are experiencing is not likely coming from the ignition itself. DA makes very good ignitions and are well shielded with a resistor in the cap. Look for the problem to be caused by some other electrical or metal components in your plane. If your flying 2.4 it could well be the radio itself.

The maximum recommended difference between an engine off and engine running range check is 10-15%. Anyone electing to fly with a 50% difference should start saving their money. They'll need a new plane soon.

I forgot to mention that I tried grounding the ignition to an engine stand off and no luck. I'm flying a JR 8103 FM with a JR Scan Select RX. This is the first time I've ever used A123s with my system. I have used 6.0V packs with the same RX and no problems.

I'm thinking of testing a spare RX I have, a standard HD switch, and a 6.0v pack just incase. I may also bypass my ignition switch as well for testing.

I am using a metal pushrod for a choke linkage as it was the easiest to operate by hand. I've used the same setup before with no problems and it doesn't seem to vibrate.

Would 2.4 Ghz be less prone to this interference or likely result in lockout?

Thanks.

Any of the name brand 2.4 radios will offer much better noise immunity than 72mhz. 2.4ghz is such a high frequency that it's almost impossible to generate a signal in that range by accident.

Of course a malfunctioning ignition can overwhelm almost anything by sheer force, but if the ignition is working properly, power is good and the installation is done properly I've found 2.4 to be bulletproof.

I have now been flying 2.4 for 3 years. I started with a DX7 and have used every brand of radio on the market. I have yet to get even a glitch when flying.

My personal favorite now is the Hitec Aurora 9, but they all work.

I guess I do need to upgrade sooner or later. Makes me curious if 2.4 would be strong enough to overcome the interference. Talk about a band aid fix.

I do recommend that you find the source of the interference first. Using a PPM receiver is a very good way to find problems because it will show up every little but of noise that gets through.

But a good 2.4 radio will make it seem as though you never had a problem.

I pulled the ignition and was able to see a small spot about an 1/8" where the strands were still in place but broken, enough for me to seperate them with a bit of pressure. Had to use a bright LED light to see it. Last time I checked at the field I must have overlooked it as the damage was very small.

I'm hoping that's the problem. It surprised me to see how delicate the shielding is once it starts to undo itself.

Trying to come up with a fix to get me through another week of flying, I did consider running some bare stranded wiring in a tight wrap over the bad section and into the good. However, it is an aircraft and I'd feel much better with DA doing a proper repair. So off it goes.

One thing I am going to do is to get some better wire looming once it comes back. I'm very impressed with the DL engines coming with the looming on the ignitions.

Got a weight of my 88" edge today.... The scale is very accurate.. I have tried a 15lb 1oz weight at the post office and got the exact same reading..I have 2 2600 mah 7.4 li-ions 1 4.8 nimh smart fly sport reg 921 2.4,8611 on rudder,5625x2 on ail.,2 5645 on ele. Alum. spinner 23x8 xoar,pin n flag(SM reg for rec.) 1 HD jr switch for Ign. I might try to loss a little weight by getting a c.f. wing tube and maybe some gear and spinner!! I don't care because it flies great!! This plane is helping me with learning how to 3d Just thought I'd post my results....

15.1 lbs is a great weight ! I'm still eyeballin this plane.....How are parts availability for this Edge??

That thing will be a rocketship at that weight!! Freakin awesome.
