I know this is probably blasphemy but I still am not ready to take the leap to li-po's I am still crashing to frequently to trust that I wont create a fireball. The crashes have not cause any significant damage in a long time to the helis but I'm still wanting to stick with NiMH since thats the charger I have.

I'm wanting to know where I can get a good NiMH Battery that will have around 1000mAh and a 10c discharge that isn't to heavy to fit in a 400 class electric heli. I've got a blade CP and a TZ-400 (revoCP from H-L) and using the E-flight 9.6v 650 mAh batts right now. The blade flies for about 10 minutes easily but the revo gets about 5 minutes cause it has a brushless and a 10t pinion. If I'm at the point where I need to upgrade to li-po I'll consider it but there are too many problems from what I've heard and I dont want to take the risks, not to mention the large amount of money for the new batts and chargers. I've got a Prophet Plus peak charger so I can set just about any charge rate I need to up to 4A.

If li-po os the only way to go is there any way I can assure a completely safe system? I dont want to have to sit there for an hour watching the heli while its on a charger to ensure that overcharging doesnt happen. With the NiMH I can set it to peak charge and leave it alone till I hear the alert that its set to trickle. I really like being able to do that. If I can stick with NiMH and get a good bat without having to get a nitro bird to carry the payload, thats my first choice. maybe I'm dreaming.

I am sure you can find a NIMH battery of that size but I think you will find that it might weigh a bit much. You are correct that there are some valid safety concerns when it comes to LIPO batteries. I can tell you however that if you follow all the safety practices, that charging them does not have to be all that scary. I fly at an indoor site where at any given time there might be 15 lipo's charging and have yet to see a problem. They are not left unattended but they are also not watched over at every moment. You have to be sure of your charging rates and also be sure that you have a reliable charger. With some common sense they can be used safely and will add a lot of enjoyment to your electric flight experience.
