so get this....the reason i wanted to go down to the 2200kv is recently at the track after 20 minutes of racing my motor temps are like 155* to 160* which is higher than i like to be. i couldnt figure it out. all summer my temps were like 130 or less. so this is when i took notice of the 2200kv motor thinking it would bring my motor temps down. but then i read something in another forum that answered my question for me. that a center diff motor mount will result in motor temps about 10* hotter than a Tekno chassis motor mount. the reason being is the alum motor plates and alum chassis all help to dissipate heat away from the motor. this was tested by someone. makes sense.
in the summer i was running the TEkno chassis mount. now i have a RCM conversion and not only do i have the RCM center diff mount but i had to make a carbon extension piece so that i could fit mech brakes. so the carbon piece covers one whole end of the motor can. so all of this is resulting in hotter temps. so i think it is finally time. i have a Tekno chassis for the RC8. the first real-world, hard-anodized RC8 Tekno conversion for the public.

so its time to make the switch. what can i say? i am just a Tekno guy. I must say, i really like the shape of the RCM chassis and how the components are laid out but overall i have had to do so many mods to try to make this thing work like i want it to. nothing wrong with the kit, just my preferences. tekno's kits are already built to my tastes so no mods required.
anyway, i am still tempted to get a couple of Tekno 1515 1y/Q's but i am gonna wait a bit. maybe Tekno will counter the new line from Castle with a square canned-long wire-sealed endbell-motor that some of us anal-retentive bastards would love to see.
