POSSIBLE BATTERY PROBLEMS

I read SF post about running a 031 for more then 10 min. causing the motor to get hot + causing the heli to shut off. I was looking at some of the mods for 107s + the 1 for a bigger battery for longer run times [I think someone said 30 min.]interested me but if the motors get hot in the larger helis what would be the effect of longer run times on the motors in the 107? Also does anyone make a tail rotor with more pitch for the 107, is there any for another brand of heli that would work? I think more pitch in the tail rotor would make it faster + able to handle slight breezes better outside. I fly my 107 + my blade scout whenever it's calm enough at night. I hope someone can give a little insight on bigger batteries. Later Lanny

I've seen someone on youtube replace their tail rotor blade, with a higher pitched blade. I can't give any references, but search youtube with something like "relpace tail roter blade", or something like that, until you find the video of which I'm speaking! Laugh Once you see this video, it will leave No Question that it's the video I'm talking about! Hope that helps in some way, but I KNOW it's been done! Smile

There's no problem, to my knowlege w. the 107's and motor overheating w. the bigger batteries. A 240mah 3.7v battery's just about the best one you could have

 

If you want a larger tail rotor, there's one made by picooz that they had for these, but they don't make it anymore. They do have speed rotors, but they're really bad for reverse.

 

What I'd do would be take some plastic, either from the packaging or something else, and cut it to identical sizes and glue it onto a spare rotor. The best thing would be styrene plastic, folded over the blade using Testor's model glue, (the red tube stuff) then glued at the rear w. testors plastic cement. However, I don't think you probably have any of those three. (That comes from my train scratchbuilding supplies. The model glue melts the styrene, and it would make it have a strong bond to the rotor, and it'd fit like a glove around it, then the plastic cement welds the ends together.)
