Let me just clear things up a bit here. Using a LiPo in a stock gun is not a bad thing automatically. What makes trigger contacts burn up is arcing, which is caused by voltage. A 7.4v LiPo actually arcs and does less damage to trigger contacts than a 9.6v NimH. I run 7.4v LiPos in stock guns all the time, in fact, I do not even own a non LiPo battery anymore.
About the issue of destroying your gearbox, that is also partially myth/partially true, mostly just misunderstanding by people who dont know enough about the topic. A DC motor will only draw the amount of current that it needs to operate, aka I could have a motor which needs 15A to run optimally, so I could use a battery that supplies 10A and cause the motor to under perform, use a battery that can supply 15A to give the motor just enough power, or use a battery that supplies 30A which will give the motor all the power it needs, but it wont pull any more than the 15A it needs. Basically the idea that a LiPo explodes your gearbox comes from the motor getting the power it needs to operate properly once a LiPo is used since generally they supply more current than NimH batteries. This causes the cyclic rate of the gearbox to complete faster, therefore getting off more cycles per unit time. In other words, using a LiPo a gearbox could complete 1000 cycles in 5 min as opposed to the same gearbox taking 10 mins to complete 1000 cycles using a NimH, giving the illusion that the LiPo caused the gearbox to break.
Now there are instances where the gearbox cant quite handle the motors new found performance due to a misalignment or something, but that isnt super common. I could go on and on about this subject, so shoot me any questions you may have.
