Replied.

Yes, it was a good launch, but I have no idea what went wrong at the end. I didn't have time to correct the bike and it went off flying in style.

Nice bike , what's the record for the bikes ?

Stop teasing now with the 200A esc when will you be selling these :smile:

They say nobody has gone bellow 2.00 yet and that's what I'm shooting for. I don't know how much to sell the 200A esc for.

Sell the esc for as cheap as possible :mdr::na:

I'm sure you will work out a competitive price , when you do PM thanks as i will use it in my 2s speed record pan car .

Question on the speed car , do you think heavier lipos are better or lighter ones . I am looking at either the SMC 28c 4000mah or 5000mah packs , but i am thinking the heavier battery would help keep the car on the ground .

Any other battery you can recommend that will handle the amps drawn with the Vortex 2.5t motor and gearing you recommended . I have chosen the SMC packs as i know they will fit in the car i am buying and they are top quality cells .

2.00 with a bike is impressive , good luck on the challenge .

I'll let you know. I'm going to make a chassis for my TC3 that will allow 2 2S hard cased lipos to be used so I can wire them in parallel, so yes the weight will help you keep the car down. The 30C hard cased packs by Enerland will be plenty good. If you have 64P gears ditch them right now. I use 48P and if you're going to do speed runs use a 65T spur and the biggest pinion you can find, but you can basically use BrianG's calculator to give you an idea of what to gear the car for.

I will have to see if the Enerland 30c will fit the car? I don't have the car yet so i am waiting for guys to give me some measurements of what will fit in it .
Luci i ddin't think you could alter the chassis in the 2s speed scale class ? or is the TC3 for another use.

I am using a 48p 72T spur , couldn't find any smaller in 48p and will start with pinions from 22t - 26t as that's what i have at the moment , should get me going for now .

Well the chassis will be my aftermarket type chassis for the TC3. My TC3 has an after market chassis in it now. Everything else will be stock. If a dragster can be in the spec class, so can my TC3 :lol:. As for spur and pinion check this out:

Your a champ mate , RCMart is next door ( Asia ) and i usually receive products within 5 days from them . Now to go order some spurs and pinions :yipi:

Glad I can help a little and I only mean a little, because I have a nice 60T pinion to use with my HV1.5 and the 65T spur :whistle:.

I am about to put the order through for the spur / pinion and just had a look at there motors . They have the Orion Vortex 2.5t which is $20 dollars cheaper at $79 than the Speed Passions Competition 2.5t . Both rated at 13,800kv , i have not dealt with Speed passion before and don't mind paying more for it if it's a better motor but just haven't heard any reports on the SP motors ?

I'll have to have a look at Brians speed calculator to see what speeds i'm looking at with 13800kv and 65/40 gearing on 2s :gasp:

You'll be flying for sure with that gearing :lol:.

Why aren't you sleeping man , it's lunch time down under :smile:

Ok just used Brians calculator , with above set up it's showing 104mph but the motor will be spinning at 102000 rpm :surprised: they are only rated to 70000rpm that motor will disintegrate :smile:

Now if i use a motor around 9000kv with the same 65/40 gearing the calculator is showing 157mph :surprised: with the motor at 66000 rpm which is within the limits .

I don't understand how using a lower kv motor will yield more speed , maybe the calculator is not working right .

I put 1/1 in the differential section since the pan car is direct drive and 2.5" for the tires since that's what foams come in un cut ?

I had my 2.5T screaming for a little while doing some testing on that windy day and the motor is still good.The motor should be able to handle 102,000rpm, but if you're worried, just wait for my motor to come. It should have the rotor wrapped with Kevlar. I'm not sure how Brian's calculator work, but it give a high percent of speed loss with the higher rpm rating.

I think it must have something to do with efficiency loss , not sure .

Think i'll order the Orion in 3.5t which is 9130kv , thats 67562 rpm with 2s and theoretical top speed of 157mph with the 65/40 gearing .

Heck i haven't even driven anything over 60mph ,and even with the 72t spur and 25t pinion i already have , that's 129mph theoretical top speed which one of these pan cars would not handle too well anyway without being modified and niether would the driver :mdr:

I think i'll be happy with a car that handles and can get over the 85.45mph record in the scale class .
Maybe the above speeds would be nice if attemting the open world record of 161mph but not for me at the moment .
