lol, hopefully the Quark treats you right after all you've been through! If it starts thermalling though, prepare to do the internal mod. It's a little bit of a PITA, but not overly hard, and is well worth it IMO. I've done it to both my Quarks and results have been pleasing.
Yeah, but if I do the mod, then I won't be able to have it fixed when the symptoms of the defects that this one has start to manifest themselves. I just know my luck.
I've already epoxied my 6 cap bank to the bottom of the Quark, and I'll have to desolder the bank to open up the Quark to check it out. I may just throw the MM back in and run that until I feel like messing with the Quark.
I am fairly pleased with mine, has strong brakes and massive acceleration. Don't have heatsink, yet, but it sure does need one will burn fingers after a hard run. Programming is somewhat difficult. took me a few trys to get all parameters right. I use a Maxamps 5 cell, runs great, plenty of power, long run times (120 amp cont. discharge, 6000mah) no problems. the monster pro is probably the best if u dont have mechanical brakes like on a G-maxx revo (i have one) but if u do have mech. brakes, use a Castle HV 125, it is about $40 cheaper, it is lighter, handles more power, and customer service is great. Be careful with brakes on Monster Pro (front flips anyone?)
yeah, the brakes can be a bit touchy, but if you reduce the break power in programming, it is much smoother.
Don't forget, the 125B is technically a 1/10 scale ESC, much like the MM. So using it in a MT/truggy/buggy, it will work it harder. Doing the "internal mod" (despite the loss of a warranty) and adding a heatsink does wonders. Also, adding a couple extra caps helps a lot too...
