RC10T3 GrassTrack

RC10T3 arrived from an Ebay purchase yesterday. Looks to be in good enough shape to put it straight-away onto the ahr43 grasstrack. Not sure what it will get for a power pack yet-17.5 or 13.5. But looking forward to laying down some back motor ST times to compare with the RC10GT conversion's mid motor times.

Check back occasionally for updates. Cheers. AC

I finally got to test drive someone else's car on Thornhill's new oval track last night, wow that was so much fun!

Motor size didn't really seem to matter much on their layout.

Glad you enjoyed the drive, Bill. Is Thornhill's oval a clay banked, or flat? Is it a tight oval or one with long straights?

The car you drove, mid-motor or back motor?

The T3 roller I just bought is sprinkled throughout with aluminum and graphite parts. Have not weighed it yet, but it is w-a-y lighter than either of my RC10GT conversions. Should be a ripper on an oval. Too fragile, me thinks, for a standard 1/10 ST track, but ideal for flat track without jumps or big bumps.

Cheers. AC

The oval is on a modest slope, the low side has no bank and relatively flat, the high side has some slope to the #4 corner but most folks were taking that corner tight and not using any of the bank. It's a fairly tight track, felt kinda congested with 5-6 cars on it last night, but it was fun trying to avoid lap traffic.

I was driving someone's spec slash and I was able to keep up with a Mod Sprint car on the track, both of us are experienced off-road drivers with similar skill, but was both our first time running oval... they ran it dry so traction was down and that seemed to level the playing field to where speed didn't matter much, I quickly learned that slow consistent laps were faster that seeing guys carry too much speed and either blow the corner or spin out frequently.

I just don't see how it would be possible for anyone to ever break any parts in oval racing, I am definitely sold and will be running the 13.5T Late Model based on a 1/10 4WD Buggy using similar rules as the Street Stock class but no restriction for sponsored drivers... really looking forward to it!

O.K., Bill. Good description on the track. I went to Thornhill's LiveRC site. Oval looks to be part of an existing track. Smart use of resources, especially when venturing into the unknowns of oval track racing.

Opening race is still scheduled for Feb 2, as related on LiveRC? Interested in class results and reading what times are getting put up.

Love a tight track. With the full-fender class you are entering, correct you are, breakage should be minimal. It's open wheel oval where stuff gets whanged.

Best racing I ever did was on a 1/4 mile oval, full size 1:1 sprint car, Beatrice, Nebraska, back in the 1970's. As you said about the Thornhill oval, 5-6 cars and the track got packed. Australian Pursuit style racing. Last car each lap got black flagged until there was only one left-the winner. Racing was quite brisk amonst the back markers just to stay in the race.

Guess I'll have to ruck up and truck it to Thornhill to watch the oval if it gets up and going. Now I have incentive to get going on the T3. Good luck.
Cheers. AC

That Aussie Pursuit sounds interesting, I am a total noob with Oval, and can't wait to get more into it!

RC10T3 on the workstand

Turned a wrench on the 'Plain Jane' T3 yesterday. Fitting up a battery a small step, but a start is a start. Need another set of foam spacers for the 'shorty' LiPo. They are still available from AE so that goes on the want list.

Rest of the power pack is a HW 13.5 combo and Spectrum 2-channel rcvr.

Truck is light already with lots of aluminum and graphite parts. Thinking I may bite the bullet on this build and sprinkle in some titanium fasteners topside just to keep the light weight theme going. Usually, I stay shy of non-ferrous fasteners as I frequently drop them and need a magnet to pull them back from some obscure part of the chassis they end up.

Lately, I've been disappointed in the carbon steel fasteners I've been buying. They surface rust in the high humidity environment of Houston, making their application seem hack. No longer, it appears, are they black oxide coated like in RC days past. Think it is "look-alike" black paint. Basically a waste of money buying them. May just as well spend the extra on non-ferrous and be done with it.

Cheers. AC

I recently bought a used TLR22 and there was tons of oxidized metal all over it... this stuff dissolved all the rust almost instantly, and it provides a nice protective finish:

WD-40 PFTE Dry Lube

I use it on all metal parts, especially to flush my bearings and CVD's, it really extends the life of all my parts

Just another RC10T3

Thanks, Bill. Picked up a can of Dry-Lube. Good stuff. Thanks for the heads-up.

Spent the last two days doing an electronics install and radio set up on the T3. It's gone from roller to ready-for shake-downs on the backyard grasstrack.

Battery pack is a GensAce 4200 2s Lipo shorty. HW Justock 13.5 ESC and motor. Futaba T-FHSS radio system. PL Edge up front and Bowties in the rear hold it off the ground. 19/87 PGR.

Cheers. AC

Silver solder?

Thanks, Bill. The roller came from the Ebay seller really clean. That helped.

Had a bit of a hassle soldering a Deans to the HW battery leads and soldering the ESC 3-wire to the motor. Had to crank up the old Hakko soldering station to near max temp to get solder flow. Suspect the wire ends came tinned with silver solder from the factory. Never did like silver solder. Tried it early on with my RC drag racing cars and found it more of a pain than it was worth. Eventually did get solder flow on the HW leads once I fed in my Radio Shaft 63/37 rosin-core.

After wandering about for ten years finally came out of the radio desert and bought Futaba again. Needed another radio with an up-timer. This one came off amain as a 'scratch and dent' sale item. Shipping and packing box had a ding on one end. Radio appears and acts undamaged. The T-FHSS was a bonus. Saved a lot buying it that way. Free shipping too.

adding brass weights

Arriving just in time from aMain came a set of Factory Team Associated No.91744 B6 Brass Under Battery Weights. They are cut to fit a LiPo 'Shorty', but a tad wide for the battery tray on the T3. Trimming defeats the purpose of a battery weight, so had no option but to trap them under the battery strap atop the LiPo.

Truck was under weight by more than 2oz, but less than 4oz. Minimum weight for my ST's by rules package is 60oz. That meant it was facing both a 2sec qualifying time penalty and a power reduction of an additional 10pts. The weight set came in at 2.4oz, and adding brass collars and SS shock attaching screws brought the weight into compliance at just a shade north of 60oz.

Race ready she is and passed through tech to the paddock table. Cheers. AC

TQ and Fast Laps Awardee

Team Associated RC10T3 carrying racing number '4' swept honors for Spring Season on its back yard grass track.

For its efforts, it wins a new set of JConcepts Carvers 2.2 ST Front Tires.

Bought as a roller off Ebay and upgraded with an install of a HW 13.5 JusStock power unit and 2s x 4600 Shorty LiPo battery, she performed flawlessly with little to no changes to set up.

Rules package holds its power setting at 60%, so it will have its hands full maintaining the pace come Fall Season. But for now, she be 'King of the Hill'.

Cheers and Regards. AC
