I switched completely to Life packs for everything after losing my Rascal to a bad NiMh pack. Damn pack tested good, held a good charge/discharge cycle, yet one cell failed after 10 minutes. I have only had one Life give me grief, but that was my fault for not taking proper care of it and letting it sit with low voltage over the winter in the trailer. Now I make sure they have a storage charge before closing the trailer for winter.

I never put NiMh cells on receivers I do use NiCd extensively. NiMh are okay in transmitters where the load is more constant. NiMh would also work fine on the spark maker.

Thats what failed on the Rascal. I have Life for the RX and a 5 cell for the Ignition. One cell went bad and dropped the entire pack to under 4.02 volts when under load. From now on, Life with a regulator for the ignitions.

Now, we or I was talking about two of my CH Ignition units having the 6v and the 7.4v options checked on the back indicating a range of 6 to 7.4 volts. However on 6 volts the spark is very weak and inaudible, on 7.4 volts it really cracks. I made a mistake buying the Lipo "Suck" battery, it has about 3 pages of warnings about charging it. Taking it out of the plane would be a hassle I don't need. You need to stay away from it for the first 30 minutes of charging, You can't lay it on wood while charging, that's only part of the warnings.
BTW, since I fly electric as well as nitro & gas, I have lots of LiPo batteries. Those safety sheets always illustrate worst-case conditions ( I never heard of staying away from a charging LiPO). Not that their advice should be ignored, better safe than sorry; but being safe with LiPos is no more of a big deal than being safe with gas or glow fuel.

LiFe and Lipo as well We had a new plane go in when a shorted regulator on Lipo took it out
NiMh are okay with constant loads within their rating but do poorly with sudden current surge demands
This is why I prefer NiCd for receiver/servo duty and generally only use them in transmitters.
I do try to avoid adding regulators and added wiring
Parts that arent there cant let you down

Years ago people called cool power cruel power,never used it so don't know why it got that name.
The smaller fg gas engines don't excite me no matter how good they are.The fg carby won't allow you to put the engine back up against the firewall which you need to do on most arf's if you don't want to carry a lot of lead in the tail.None of my fa powered models need it.

Too much stuff to stuff into a plane

I got em all in there in the LT 40 and they're neat too. I am controlling it with the tiny AR 400 Spektrum and the latest DX7.
Somehow my Boca Bearing order got hung up in some no name town in Va., the order got to Richmond at 2:20 AM this day. The USPS makes Amazon runs through here on Sunday, I don't know if that helps me or not. I'll probably get them tomorrow.

I lived in Kansas for a year and a half Pete, or Rudy, or well, Old Fart. I hated every day there. The wind blew steady almost every day. I would guess that model airplane flying was a once a weekend per month kind of thing. I heard they turned all the roads there to one way streets....all leading out of Kansas.
Just watched the Top Fuel final drags this evening. A Suzuki almost took the Harley, but he was late out of the box.
I flew Lipo's for several years teaching college students how to fly indoor electrics. We used the old basketball coliseum, which was huge. I had 2 chargers always plugged in charging 4 batteries each. I think we had 2 swollen or hot batteries in all that time. But, these were mostly the small types. Still, I don't trust them. I wish I had a way to tack weld the pig tails so I could make my own battery packs.

Good to see you made it out of kansas maybe they could use the place to store all the old lipo's. I sometimes watch top fuel drag racing and there don't seem to be many harley bits in the 'harleys' whereas it's common on the jap fours.The road manners over here get worse year by year but it's the cyclists that pee me off most so i'll post a pic of my retirement scooter i'll be building and riding once i get too old for the ducati.
ps gary not sure what you mean in your post.
pps dave WHAT paint are you using to do the barrels on your saito fa90 twin? and would you like to see how they take a stocker harley worth about 20 grand over your way and turn it in to an art nouveau US 1.9 million bike.Don't hang the pic on the workshop wall your harley will turn green..oh wait

Some of KMOT's work, I keep some of his pictures to admire and and get ideas.
Clean up, the stuff is nearly a Miracle Worker.
Paint, I finally developed the touch in spraying thin coats spaced about 10 minutes apart. It seems to be durable.
This engine almost didn't need cleaned.

In our area we have had two major home fires caused by LiPo batteries These are apart from fires at local flying club fields
Fortunatley no loss of life yet but major home damage and total loss of vehicles

Charlie, the 1600 I have is two cells and 7.4 volts. I have since found that SR Batteries and No BS Batteries have 6 cell NIMH batteries. I have used both before and they are reliable.

These are what I use
Glacier 2100mAh 2S 6.6V LiFe Receiver Battery
I put Enloops in my JR 12X radio, uses a standard NiMh setting, and is working out very well.
This is what I use in the LT-40 for the FG-11 and RX, note the two output leads.
