wow DUDE.. Killer!..

I can wait to see it all together..

How fast are you planning on running it ?? and how long do you antisapte before you'll have it done ??

Ok so you shooting for 55K out a 60K motor running 12s and the bad boy weighs 26 lbs that's insane / tons of mass behind it. Please post some pics when you wrap it around a telephone pole doing what 100 mph..

Now you just need to strip it down, clean it up and spend a lot of money!! (oohh how i know that feeling)..

Another killer build / project for YOU.. two thumbs up..

P.S.
keep us updated Sir and Thanks for sharing the lastest and greatest money pit of your's..

Good luck with the GTRe. I had one and thought it could do with quite a bit of work to be competent for high speed. The center brace limints battery height, mine had alot of drag in the belt setup, and the barkes just did not work well. Plus that big electronics box is kinda dumb, it would be better to have a battery tray on that side too. And you motor choice will be a bit limited due to the special 3 gear pinion with 1/8 bore. Maybe get a medusa 50mm with 1/8 shaft, but I think a larger motor would be required to run 100mph...

Sounds like an interesting project, I have only seen a few GTPe floating around, I had mine well over a year ago. It was brand new when I got it.

hey pimp,
so do you still have your GTRe? i have heard that these are pretty rare. at least that is what the guy told me that i bought it from. but i noticed you can still get them on the schumacher site.

here is what i am going with. i have looked at all this stuff and it all fits pretty well.

Mamba Max ESC
Castle 5700kv motor (1/10 of course)
losi 3200mah 3cell lipo (would like to run a thunder power but wont fit....maybe with some mod i can make it work)
2 jr9100s servos
many alum and titanium schumacher upgrade parts

as for the 100 mph you may be right. many of these 1/10 brushless motors push the RTR trucks at 70 mph out of the box so i figured that this GTRe with the 3 speed would do 100mph+ with those extra gears.
i assumed that 3rd gear would be very tall and that 2nd gear would be similar to the gearing of the single geared RTRs that do 70mph.
well, after looking at the gearing it appears that 3rd on this GTR is about the same as the RTR stock pinion and spur setups like the Rustler and the Losi speedT. anyway, i may just have to scrap the 3 speed trans and come up with something different. will just have to wait and see. But i know these motors could do 100mph with the right gearing. if my Rustler VXL had a 2nd gear....whoa.

imo in regular setups, gears = something more to break lol. kiss :)

hi

i would also target around 25'000 rpm. a good tuned zenoah does bout that.
those cars are geared very high so you need a high torque motor. the 30er lehners seem to be about right or the plettenberg bolido. there also the pinions fit directly on the 10mm shaft.
a schulze 40.160 should do the job. if the promised XXL schulze 40.300 come out soon (?) those would be even nicer. i havn't converted one of my FGs yet but personally i would also do some kind of small watercooling circuit as there is some much room in those cars.

bye

hey rhylsadar,
where do you get parts and stuff for your 1/5 FGs? i havent been able to find any good site for 1/5 scale hop up parts.

Ryu James · 11.02.2008, 07:15 AM

just an update. i am waiting on carbon fiber sheets from dagraphite.com before fabrication begins. also, i am awaiting my ESC.

Ryu James · 10.29.2008, 01:49 AM

all i can say is TRUE, TRUE, TRUE!!

true that its lots of money

true that i will wrap it around a telephone pole

and true to all the other shit you said too!

here is the plan: 60mph car finished in the next 4-6 weeks. i would like to say it would be done sooner than that but just being realistic when i consider the money and time.

does anyone here know where to get a 8mm shaft pinion gear that will mesh with these 1/5 scale gears?
