My plans to build mine myself

John Wallace2

I race at RCHQ off road and dirt oval on the old track before it closed and 1RC oval and just getting into mini Z at the new store. Danny Finley is pushing F1 here and he has made improvement to the track to help keep the F1 front wings from getting stuck under the boards; changes that have benefited other classes as well. He plans on having two F1 classes: F1 and F2. Both have identical specs but F2 is run at 50% throttle. Both classes will have 3500KV motors, Blinky ESCs, 10T pinion/stock spur gears. Saturday the F1 the lap times were comparable with the stock class and about 1 second slower than super stock. He plans to have F1 style pit stops. I have my kit and all the parts needed to build my car but I’m interested in the F2 class and that doesn’t start until November. So I guess I’ll just work on my stock car for now.

That is awesome news, hopefully that program picks up enough where it becomes a trend setter for other tracks to model after...you can suggest to Danny Finley to take a look at the UF1Series Format of pit lane procedure and even point syste etc so see if he see's fit to incorporate any of those ideas to his own final format...UF1 series in short is a 10th scale F1 Class Only Series ( also ran as a single day event) runnig for over 10+ years and works pretty good, ....here's a link to that page, most 28th scale relevant info will be under section "Additional Rules" almost in the middle of this page >> https://uf1rc.com/rules-and-regulations/

Hi, I ran the UF1 10th scale series in Houston Tx. The MF1 series that I am currently putting together will run very similar to UF1 in many ways. Our first trial race is coming up Dec 11 with our series starting in January. We are also incorporating F2 into the mix which has the same spec as F1 but is ran at 50% throttle for new and novice drivers.

Glad to hear your F1 program is coming together, about time F1 class got the attention it deserves in this scale, will be following videos and results online.
If youre running 3500 in F1 the 2500 w/full trottle for F2 may also be a good option, I used it extensivly in the past, has a very smooth, managable power band and top end and no one will have to wonder if winner messed w/their TH high point LoL...surpass 2500 still aorund 20 bucks on banggood i belive.

The F1 class at the upcoming GL nationsals this weekend with 9 entries I belive is the largest to date on a national level this side of 2012 PNWC ( all kyosho F1's back then)...hoping to see 2 full heats at big events held next year.

We are excited about MF1. We have a solid set of specs and race formats in place. Our trial race is coming up on Dec 11 in San Antonio Tx. We are wanting to expand our MF1 idea to other cities and states and would like to hold a national event in time. Right now we have San Antonio, Houston, and Colorado on board. I expect more than 20 F1 and 2 entries in our December race.
I will be starting an independent thread in the forum next week.

i thought about the 2500 for F2 but I wanted the car specs to be identical in both classes so those in F2 who want to move up can just turn up the radio and race. No further expenses for a motor in either direction.

That makes good sense.
Alternatly limiting pinion in MF2 to 9 or even 8T ( PN makes64P 8T in aluminum - Part#: 420218) could be another way to cut back on power delivery ... either way, important thing is a beginner class is offered.

I like that idea although I don’t think 8 is high geared enough unless I can find a larger spur. The car would need to be roughly half the speed of a full out 3500 on a 35/10 ratio. I may test some things out to see.

If going the gear swap route then using PN's .05 pitch 44 tooth spur (part # MR2044B) along with Kyosho 6T pinion will max out the gearing to 7.33.

PN 44T spur should be a direct fit on the GL's axle as their yellow 53T spur w/same measurements fits.

Too bad PN doesnt make a 6T promatch pinion (7t is the smallest they make) as they are much smoother than Kyosho pinions but Kyosho's will do...but anyway the 7.33 ratio should numb down the fiesty 3500 on lipo but still need to test see if enough.

Was able to test GLF with .5pitch 44 spur but the 6 tooth kyosho pinion would not slip in enough on GL rotor shaft to engage teeth w/spur ( pinion drilling trick didnt work that time, broke the pinion) so ran it w/a 7 tooth PN pinion which did fit (pn doesnt make a 6T .5 pitch pinion) ...the top speed was tamer noticably but acceleration to that more comfortble top speed even though was also tamer a bit was still pretty peaky ...overall still too fast for the purposes of MF2 beginner / sportsman class ...6 tooth may do it, next time will try get it instaled before getting to track.

I generally feel that a smaller pinion makes the car harder to drive. Larger pinion may provide more top speed, but it takes away the wheel spin on throttle application and calms the car down.

Despite the fact that you want to use one motor for both classes, I think it would be better to use a 2500kv motor for the F2 class, and that it would yield a better outcome overall. You can use a 11-12t pinion to have roughly similar top speed to the 3500 with a 10t, but there will be lower torque on throttle application, and that is usually what makes driving difficult. 2500kv with a 12t is roughly the same top speed as a AAA 3500 stock class car, with slightly higher acceleration off the slow corners.

IMHO, limiting top speed a lot with gearing leads to more issues than it solves. It removes the ability to cut down tires to maximize contact patch, or just run them for a long time since rollout becomes more important. (this is directed towards both F1, F2, and even SuperStock wherever a short gear ratio is used to limit speed). It also pushes people towards alternative directions to try to regain that speed, through motor tuning, or people having to mass purchase batteries and motors to get the "best" to be competitive. I personally prefer open gearing, or a large gearing range, which lets the user to gear appropriate for the circuit, and their ability/preference. I would personally choose 3500 for F1, and 2500 for F2. Yes, its another motor, but the 2500's are pretty cheap that its not losing much to go from F2 to F1 when you graduate. I would just limit them at 13t, since they seem to cog at 14t off slow corners (I tested 10+ to try to balance against AAA 3500 cars for stock racing, but it didnt work). Just adding my two cents.

Well it’s back. I’ll probably end up adding the LMP body
