VTA Racers..

I have the Newest 21.5 based DUO based motors in stock. These motors are great for VTA racing and any other 21.5 type class of racing. These are great for that racer looking for a top running motor. Timing ajustable,Vented for lower temps and great clean windings. If you are looking for a nice motor at a great price have your local hobby shop contact me or you may do so at [email protected] .

If they become legal then I would love to run them.

Well, technically they're not great for VTA since they're not legal. If things get opened up I'm sure they'll be an attractive option though!

I hope Seaball will come on this thread, as he did not run 21.5 until Sunday (borrowed a motor). I think he could shed some light here.
first, congrats to haynes for putting it down on all of us. he didn't do it on rip alone, so let's get that straight. nobody drove like haynes did this weekend, and it didn't appear that anyone's car would corner like his either. that should not be a surprise to anyone, considering his vegas performance of two months ago.

i've driven t/a on two occassions, both with borrowed gear (car, radio, and power). on both occassions, i feel like the few cars that stood out in terms of power were using the 21.5/lipo combo. you can't really use lap times, because the sample size is just too small. even at our 240 entry halloween race (with 30 some t/a cars) there weren't a ton of drivers that could get the cars around the track very tightly. i drove like a total idiot, and still found myself inside of cars way too often for an 'a' heat/main.

getting back to the power thing, i'd have to rank the current options as follows:

21.5-L > Brushed-4 > 17.5-4

the 21.5 just makes more power. it jolts out of the turns and seemes that the 4.2 ratio is as wide as you'd need to go on most tracks (so it's not really a limit at all - as haynes implied).

the brushed motors were first proven faster than the 17.5's in the spring when they were both an option at the carpet nats. at that time, we tested some in a very controlled manner and the brushed motors (that we had) were simply faster in top end and showed a heavy .2/lap advantage (on a normal, 12 second layout). perhaps they have evened up by now, but i still have my doubts..

the 17.5's seem a little weak to me. with the tall ratios, they suffer on the low end, and as a brushless motor, seem to lack any real rpm to pull the length of the straights. there are exceptions, but this is what i've arrived at in the two t/a races i've run.

for me this weekend, my 17.5-4 combo was junk. however, my sticks were (i don't know) how many months old, and the 17.5 was said to be 'getting weak' by it's owner. so yes, when i switched to a 21.5/core-5K the car was ridiculous amounts faster, and i would agree with haynes that i probably shouldn't even have been at the 4.21 that we used.

like robk said... in the end, haynes was the only guy who 'showed up' this past weekend. good job michael!

I have noticed a few instances where dropping back from the 4.21 resulted in a faster lap time. Not personally but in the post on this thread.

I wish I'd known this 2 months ago! Now I feel like a low budget race team locked into a bad design and lower performance equipment. I've decided to run what I bought for the year. I think my wife would shoot me if I asked for LiPos, a charger and a 21.5 right now. Wish me luck on dialing in the chassis, getting lots of practice and trying to get enough out of my package to be somewhat competitive with the field.

I understand ROAR has 21.5 specs in the works, so hopefully they will approve motors in the next few months. Doug has said he will consider opening up 21.5 if ROAR approves motors. The main consideration now is that 21.5 is more or less wide open. It's hard to know what each motor will run like, and what specs it is built to.

I work at a hobby shop. I've always had Novak 21.5's in stock. There has never been an issue from my side. Bottom line, please don't change any of the rules. We all have the choice of what motor/battery we choose to run. Some choices make you have to learn how to save money to get them. Keep the rules tight to keep the drivers in line. The more it's opened up, the more they will complain that they want more. Ive run this class since May, have run all 3 combos. Love it just the way it is.Don't go changin'.BC

Not sure what the chances of this happening are, but I have to ask.

What happens if ROAR approves a bunch of 21.5s and Novak isn't one of them?

hey guy's. i wanted to give my opinion about the 21.5 v 17.5, the last race i particapated in, i had a 21.5 and a friend had a 17.5. i was at 4.2 fdr and i don't know what he was at. we lined up on the straight and he out pulled me by about 3 car length's. i had to set my speed passion at top motor timing before we became dead even. he has tc3 i have ft tc4 and our weght was within 10 or 15 grams. i am about a 2 year rookie at this but im not seeing what others have seen. the 17.5 with open fdr is smoking fast. i wanted to ask them if i could drop a few teeth so i could put the speed passion timing back down. ( i thought that was not good for motor)

Now guys are talking about slowing the class down.
What about something that will help to even out new chassis to old chassis.
That great equalizer weight.
We have been running our TA class with the rubber tire weight limits from ROAR. That will not cost anyone hardly more than 5 dollars for those servo taped lead weights.
It makes the new losi r the same weight as a tc3.
