The 414 is pretty old school and designed way way before brushless and lipo was around for RC cars, not sure if lipo packs fit and not too sure how the drive train would stand up to modified brushless power.

The TA-05MS was actually quite good in stock classes, I used to run one in 17.5 and 10.5 boosted classes and it had good steering and nice balanced handling. I tried it in mod for a bit but the belts were a real weak point , lipo packs fit fine only issue is space to mount the esc behind the servo with that layshaft assembly taking up valuable space but it's ok if you use a low profile servo.
