That dirt oval body should work fine, but will still benefit from rear stabilizers, splitters, diffusers, et cetera ad nauseum.

When making these nessasary add on pieces can I make them of .040 or the .060 all the better ??

I'd use .040, plenty strong enough

I've used the same with 1/8 aluminium rivets before to great effect

Thanks !

Correct me if I'm wrong here but, IMO, the dirt oval bodies should have decent front down force with their wedge shape. I'd think a splitter would be all thats needed in the front.

Bondo, PBO posted a pic at the top of page 2 that shows the vertical stabilizers mounted to the sides of the body. Thought I'd mention it if you missed it as its a simple way to do it and would make for a clean look on a dirt oval body.

Yes I did catch that, just ordered a couple sheets of .040 and one of the .060 to make these with. I'm hopeing the wedge nose will help ?
I just heard back from our salesman from Horizon and he found the kit I wanted and shold have have in hand by the end of next week. I settled on the Ofna HyperE-dirt oval, it was $149.99 sweet !

thats a good deal on the dirt oval.. I also used .040 for my stabilizers .. good luck with the project. I might look into the dirt oval kit also.

Nice...can't wait to see this build take shape. Post lots of pics please

I just checked the price of a Ofna Dirt oval body, a whopping $63.... no thanks...


Nice deal on the Dirt Oval Bondo! I have a GTP roller on the way that I'll be converting to 4s and trying to break 100mph with. Can you feel the amperage???

I will, thanks for the support.

Yes !
I thought about the GTP but couldn't get a roller/ARTR through Horizon, I didn't want to lay out the extra cash for the nitro garbage and then resell via the Bay.
Especially when the AM TX/RX is worthless nowadays ?:whip:

Yep, I bought it used off rcgroups for pretty cheap so I can't complain. I'll have 5 times the price in motor and esc alone... HAHA It will be interesting!

I found them on Fleabay pretty cheap also;

Lots of places are out of stock tho...

Just to be sure, but these are sold in pairs correct?

Indeed...:yes:

I have two sets of those GRP tires for my buggies. Just make sure to warm them up well before doing a pass at WOT or you will get nasty wheelspin.

I hate i didnt get to this earlier, but i have an ofna dirt oval and it has an offset chassis to aid in left turns, dont know if you realized that, also the stock body that came with mine also has a slight angle to it that helps left turns. Mine turns left really well but it is engineered not to do right turns well and it tends to drift left when going down the straights unless you keep turning a little to the right. Of course i drive it on an oval so i also made sure to put my battery as far to the left side as i could get it. Be warned though, everything on the car is optimized for left handers.

I read this elsewheres also. I hope this can be compensated for for Bondo's sake...

Not to argue but from the pictures it doesn't seem to be anything that can't be worked with, It actaully doesn't look to be as extreme as you say ?

I have a Losi 8ight Nitro CD/brake assembly, I wounder if I could get Mikes mount to work w/it ?

It probably isnt anything that you cant work with, i just wanted you to be aware that you may have to be careful how you set it up by keeping things as close to the center or to the right as you can to compensate for the offset.

Thank you for the heads up Fast88.

Steering will hopefully not be an issue because you will end up shortening the EPA & dulling the dual rate anyway

I like running the GTP in a straight line. Takes a bit getting use too with the solid center diff. I can't launch at WOT, but have to ease into it. Saves ring gears that way too. I did get the hardend ring gears for mine. The stock ones didn't last long. Don't need crazy torque either so a 1512 or 2 pole motor is sufficient for my setup. My 2 pole motor has plenty of topend where it counts. My buddy is running my old 1515 2700kv motor in his GTP and loves it. He has plenty of ring gears at hand though.:lol:

I'm going to try to install a Slipperential w/mech brakes . Hope I succeed ?

Looks like a LX1-e with different shocks, towers and the like for dirt oval duty. The a-main link says 15mm offset hubs are included, doesn't say if standard ones are too. But thats probably where most of the left side bias comes from. Also that the shock tower is dirt oval specific, doesn't look like its biased one way or another in the pics though.

Thats why I posted these pics, I was having difficulty seeing the biased ?

Not the best pics, but this is how mine is.

Looks great Snell !
In the top pic, those tires look like whats comes in the kit, how are they ?

Thanks

Bondo- I think those tires are Ipanema(sp?) tires which have a very good and sticky compound.

Yup those are the Ipanemas. I forgot what shore they are. It's either 45 or 50. Works really well on concrete streets. No ballooning.....I did managed to unglue a small section. My buddy uses the GRP's and I like them just as much.

The bottom one pic has to 15 dollar Suprasales tires. 15 bucks for 4. They are only good for 30mph.

I have a set of the GRP's coming. I know they are good for higher speeds and have been tested.

Bondo- are you going to use the Dirt Oval body or try something else?

The 15mm offset hubs must be a company joke, because with tires off i fail to see one side being longer:neutral:. And they are definitely 17mm in diameter. The offset seems to be mainly on the chassis, if you turn it upside down, the screws connecting front and rear bulkheads arent in the middle of the chassis.

I had a set of the Superasales slicks, after balanceing them I had them over 60mph MANY times on a Lightning 10 build and they were alright for what they were. I honestly dont think I'd trust them on a build of this caliber ?

That is my intention, yes. (not selling it)
I really like the look of the oval/late model style body and hope to make it work.

I noticed watching some drag videos that some of the guys running top fuel type RC's have a small vertical fin running lenth ways on the front/nose area of the bodys. Is this something that may benefit if I incorperate it on the "splitter"?

Can you please post a pic of the underside of your chassis.
Thank You.

60MPH! Man I wish I could do that with the suprasales ones. I reglued them countless times. I can't really bitch though, as they are so cheap.

Here's a pic I took today of the bottom of my chassis. Notice that it's a bit offset. Second pic shows the GTP2 chassis that I took at the LHS today. Excuse the crappy iphone pics.

Romano- what battery box are you using?

I'm looking at the steering servo right now. I have a ACE 1015 which is both strong and fast and will be plenty in a GTP. Most people end up dialing out dual rate and EPA for high speed running. Is this steering servo really necessary? or should I look into a different one?

Thanks again for the pics Snell, the offset is nothing that can't be worked with I dont think. Your efforts are appreciated Sir !

NitroSniffer, I think anything is going to be overkill for straight line duty. I have a NIP JR-650 I'm gonna throw in mine, decent strenth and reliability is my bigger concerns than speed.

My buddy uses a fast servo, but I just use a plain 'ol slow digital metal gear one. I forgot what model number. I can check later.

Nitro,
that is not a battery box...it's one of those plastic tool drawer things. Tall and wide enough for my cube A123's.

I hear ya Bondoballz. That pretty much what I was thinking. Just thought I would get a few opinions on the subject.

Whats the word on ride height? I know the downforce will compress the suspension a bit, but how much? Is this able to be calculated?
