Probotector Posted May 18, 2013 Report Share Posted May 18, 2013 I'm interested into buying a TM Type 89, but it unfortunately has the problem of limited battery space. Only a 8,4V stick type stored in the handguard will fit and I plan on upgrading it (after some time). My first thought was cutting away some of the barrel assembly in order to cram one extra cell into the handguard, but I'm not sure if that would cause issues later on (pics would help a lot). However a more elegant solution would be to use the stock as the battery compartment. Can someone tell me the dimensions inside the stock and if the V8 gearbox allows rear-wiring? Thanks in advance.

hawaiianjuggernaut Posted May 19, 2013 Report Share Posted May 19, 2013 I only owned mine for a little bit, but this is what the best option I think is: Wiring it to the outside is really easy, drill a small hole under the bottom of the stock and wire it out that way. There IS enough space in the back stock for a 7.4 stick LiPo, It's just a pain to take the rear butt pad off. Its connected to a sling mount and has a little hole thing an blablablaha... Anyway, in short, yeah, there is space for a nice 7.4 LiPo in the back stock I found it easier using a battery sack via wiring out a hole in the bottom of the stock Apologies for not having more pictures of it Link to post Share on other sites
Probotector Posted May 19, 2013 Author Report Share Posted May 19, 2013 Thanks Jug. I think I'll settle for a LiPo then. There is a first time for everything. Link to post Share on other sites

Libris Posted May 19, 2013 Report Share Posted May 19, 2013 I run mine on the 1,600mAh lipo stick batteries. I uprated the spring to give around 320fps but that dropped the rate of fire with the NiMH. The lipo brought it back up to around 900rpm. Link to post Share on other sites
