Default Would this work? (complete chassis overhaul)

I am going electric on my next buggy. A Hyper 9e with a Tekin RX8 system with A123 style batteries. I have an old Hyper 7 that I was thinking of converting over to an short electric truggy, just to mess around with in my yard. Just looking to see what people thought about how well it would work. It does not have to compete with true truggies, just as long as it goes and handles decently I'm happy.

These would be the parts I will get to do the conversion with.

http://www.nitrohouse.com/catalog/pr...oducts_id=9736
x2 for the F/R diffs to gear down to compensate for the big wheels
http://www.nitrohouse.com/catalog/pr...ducts_id=10741
to add 0.5 inch width at each corner so truck wheels will fit
http://www.nitrohouse.com/catalog/pr...ducts_id=17523
gives another 0.5 inch width for wheel clearance and bring everything to more truggy like widths

And of course the parts needed for electric convertion.

Will power it with a hobbywing 150a esc and 2200kv motor combo. I hear that the ESC is decent and the motors run fine on 4S and less. Its cheap and this is not going to see serious running conditions, so it will be plenty.

Any thoughts, ideas, or parts to get, feel free to speak up.

Ok, its not a complete overhaul, but its a complete change of function.

hobbywing ESC is freaking awesome. I have one running tekin motor and it's rocks. it actually has a sensor port too.

I'd take hobbywing esc over CC MMM any day

Its cheaper than buying a new kit, and the 7 is in good shape, why retire it. Its at least as good of a kit as a cheaper brand truggy, and there is still plenty of hopup parts around. Any thing I should add to the list?

I read that they build the venom, orion, and speed passion esc. Their motors seem to have issues at higher speeds and voltages, and its only a 2 pole motor so not as strong running, but its enough for this. My friend runs a MMM with a nue 1515, its a good esc, but he had problems with it at first, but since he started running 4s only he has no problems at all. I will be running all tekin in my new buggy, I like the dualdrive mode it has.

looks good but I like the large capacitors on the original 150a.

i have a tekin esc sitting on top of my desk. I have no issues running the hobbywing and feel no need to change. it out. though it be an easy swap since I run 5.5mm bullets on all connections.

ya hobbywing motor that comes with the 150a esc sucks. I ran with 13t pinon and with 4S it ran up to 200 degrees.

Wow, thats a high motor temp. I may just get the ESC and find a decent motor around the $100 to $125 range. The hobbywing combo costs $190 and the ESC alone is around $95. So whats the big deal with an extra $25.
