For bashing use themsupplied tires , for racing on track get some grp soft . Don't think that Orion 2800 gonna last to long , get 2200 or 2650 castle or even the hpi flux version which u can sometimes score on eBay cheap and new . Got my gtp for 170 shipped new so there cheap . But when u add carbon fiber chassis , shock towers , and different other cf bits its not cheap anymore lol
Get a good servo I always put,my spare traxxas 2075 but u need a good one if racing

Got the motor today, and it's actually a 2400. Should work good on 4S, and if it's too fast for this track, I'll run 3S. I always use good servos in my cars. What's a good starting point for shock oils and diff oils?

And now for something completely different...

Take 1 part OfnaGTP2e,
Add 1 Part SnR Carbon 360mm Wheelbase Chassis,
Cover with a creatively trimmed Associated SC8 Truck body,
Add 1 Ofna DM1 1/7 Wing



Just debating on what style of paint i want to go for on this one.

May mount some Xceed Drift Tires on here that i have on the way...

Default gtp2e

i recently got one myself and could not be happier.im running mamba 2200kv on 6s and its awesome.with the size and weight of these cars i have foung they perform best with 1800-2200kv motors on 5 or 6s.i installed the rc monster single speed adapter and am running 40 spur and 29 pinion for speed runs.my dm1e has 2650kv motor on 4s and it runs hotter and does not have the torque to efficiently get it up to speed.im new to forum and just wanted to offer my 2 cents worth on this awesome car.

Got my wing. Crazy fast shipping from nitro-house this time around.
Usually wait a couple weeks or more.

Now the wait for paint. My painter is all sorts of backed up right now.

Last high speed run I did, the Foam tires exploded.
I have now fitted some Xo1s belted tires on the GTP2e.
I need to trim the body a little bit to clear, but hoping for over 110mph next time out!

Does anyone make a rear locker for the differential?

Thinking about having a drift differential handy for mine.
Just wondering if there's a spool or anything made by anyone that i can drop in an empty housing. Or should i just buy a new setup and go heavy on the fluid?

I dont know what weight is in my current rear diff but it is very light compared to the fronts. AFAIK its stock. Works great on road though.

Most just use putty in the rear diff to lock it up.

One point to consider is the lipo temp. I use to do lotsa electric high speed aircraft runs. The fastest passes were always 3rd or 4th after things got warmed up. To be fair, voltages and temps should be the same when running such comparison tests.

Rear diff had nothing but grease in it. and very little at that.
Didnt want to lock it right up as i still drive it with grip tires as well.
Had some Traxxas 50k diff lube at the house still so i went with that.
Already feels way better. May still go a bit thicker though.

The 1/10 scale guys do use "cleaning gum" to lock up a diff.
It would also be possible to fill it completely with a two component epoxy.
This will lock it up for ever and has same function as a spool but it is much cheaper.

If it does not work, buy a new one. Most probably still much cheaper as any spool.

ok so with the 50k in there this thing pushes like mad. Thinking camber and toe might lend a hand to correcting this? What should i be looking at for a basic drift setup on the GTP2e?

You were on the correct path when asking about a rear spool. 50k is nothing. You need 300-500k or putty like was mentioned. There is rc locking putty for that purpose or use window glazing compound/plumber's putty.

A spool in the rear and lotsa camber up front with one-ways is the drifting method with rock hard tires all around.

You cannot have both worlds of road racing and drifting in one car unless you can find a hard tire. Then just change tires. Tires are the #1 thing when drifting or road racing. PVC pipe tires works well on my micro RS4 for drifting!
