Default Tekin FX or LRP QC3

Want to build a F104 and keep it stock with the silver can. I'm not too familiar with brushed esc's. I'm on the fence between the Tekin fx and the LRP qc3. Any help would be appreciated, If you have any other suggestions for esc's that would be helpful too.

Thanks

I am not familiar with the FX but if you don't know, the QC3 has a Lipo cutoff built in so you can use it with peace of mind if you go that way. The BEC is quite good at 6V 3A too and a small footprint. I have one in my NGX F1.
Another good one is the GM V12 or V12XC if you find one (no Lipo cutoff though).

I'd go with Tekin. I liked the Fx Pro better than the QC2 that I had. Tekin's customer support is the best in the business as well.

Both are good ESCs but I had problems with my QC2's BEC being too weak for my Spektrum receiver. Didn't have any problems with my Tekin FX.

battery eliminator circuit - so you don't need a separate power supply for the radio. The tekin fx also provides 6v 3a and has lipo cutoff. It has plenty of punch for a silver can motor - you probably will not be able to feel the difference between the fx and the fx pro while running a silver can or any 27turn motor so I would save money and buy the fx instead of the pro. Also, the fx is pretty small so no worries fitting it.

TH QC3 is the updated (and last) version of QC speedies. The QC 2 doesn't have the Lipo cutoff, and lower amp draw available (from memory about 2A?) through the BEC.

The V12 and V12XC are speedies made by GM (Graupner models) in Germany. They were the first to use surface mounted FETs which brought ESCs into the realm of current day size, and deliver currents upwards of 100A continuously, introduced Turbo, traction control and launch control. They were so good, even though they came out in the early 90s, there was basically no further improvement brought about by any of the brushed ESCs after that (let alone for Lipo cutoff which was only a feature of the very last few brushed ESCs, by which time the V12/V12XC were long gone out of production).

Not 8083. 80810 is what you're talking about. Names are a bit confusing, but 80810 is designated "micro" whereas 8083 (the "normal" QC2) isn't.

So are both esc'c pretty much the latest and greatest and just a matter of preference?

Or cost/availability. The GM V12/V12XC are going for peanuts these days (especially on german ebay). The QC3 not so much so, but every now and then you can get a good deal (sometimes a NIB). The QC2 is not a good choice because of it's limited BEC output (a strong servo can pull over 6A and sometimes up to 10, let alone you need to cater for the radio). Don't know about the Tekin.

For F1 silver can the Fx is hard to beat. It's small, super light and has all the features you could ever need.

The B1 also will fit this bill and is a bit cheaper than the FX. It's also smaller and even lighter. It's about the size of a personal transponder and as long as you're using it for silver can racing is more than enough speedo!

Thanks for the help guys, I appreciate all the information.

How long has the fx been out. I heard the qc3 has been around forever. Maybe "old technology"?
