The next cheapest way to run the same radio for your larger scale vehicles and the mini Z is to get a ko propo EX2 and set it to mhs mode. The EX2 runs fhss for the larger scales and mhs for mini z only. The only issue is that only the pro VE boards can take this frequency. I had to covert my MR03 VE to a VE pro board just to consolidate all of my racing transmitters. The ex 2 is actually really reasonably priced at $250 and you can get knock off fhss receivers on e bay for $30 a piece so if you are willing to switch everything over, this will be the easiest way.

Kyosho FHSS is the one you are looking for. Compatible with kt-531p and ky-432pt radios.
my issue with the futaba rx released is that there are already many futaba customers with existing transmitters that would love to use them in this scale if they could. Forcing them to a new radio doesn't help the scale at all. Perhaps they felt that the older radios wouldn't utilize the speed of the evo electronics to its full potential, but for the most part, ease of conversation and adoption of the able in my opinion is of greater importance that response time that the newest radios have over the ones released in the last 5 years.
People are still competing with radio systems over 10 years old, and doing quite well. Having the latest and greatest response radio doesn't really make that much of a difference compared to a familiar feel and adjustment of a radio that you are comfortable with.
I would have preferred an rx compatible with a broader range of transmitters, even if the response were a little slow in comparison to the one released. The scale right now is more accessible than it has ever been, but that is not really by kyosho... more by the aftermarket micro electronics being cost effective. It is cheaper to build a modified car on a GLR platform than it is a pro stock level mini-z with the suitable hop ups, especially if you need to get a radio for the mini-z but can use an existing radio for an aftermarket platform.
just my two cents...

Unrelated, a friend at the track had the spring in his KT432 fail on him mid way through the Sunday race program. Any thoughts where to get a replacement? Looks similar to most gimbal springs in flight radios.

Your 4PK can be used with Mini-Z's. There should be a tutorial over on MZR that lays out the conversion. Basically the 901SM module is de cased and installed in the battery compartment with wiring fed up through the hand grip to the non transmitting side of the main switch for use with just the ASF module. The draw back would be that you would then be limited to only the ASF system which to me is still the most stable platform.

Pn 70t or 3500kv ve
Hi to all you guys. I play mr03 stock class with 3500kv ve with nimh batteries and I don't have enough power as pn 70t has. Can I go something to get the same power at least?
thank you
thank you

In order to compare with a 70t, you need to use a larger pinion on the 3500kv. There is more low end torque on the brushless motor, but it does not have as much RPM. What motor, batteries and gearing are you using? How large is the track?

I brought up the 3PK mod because there were references to it in the 4PK thread, so I wanted to bring the readers up to speed.

Edit: to keep it simple I would start off with 51/14-15 gear ratio.

PN makes 64 pitch pinions up to 16T...you can experiment with the bigger pinions and perhaps drop down to 51T spur & as the next option try experimenting with smaller or larger rotors...there should be a combo there that produces good results. On medium sized 22-25 tile long tracks even though top speed is slower than 70T the higher bottom to mid torque level of 3500kv motor produced overall lower lap times for me from memory with 51/12 gearing with the standard 13.5 rotor.

I use 14/51 with my 3500kv motors. I haven't tried larger 64p pinions, but have tried 11/41, 12/41 and 13/41 48p gears without any noticeable improvement in top end, but less power off the slower corners.
I just picked up a 16.5mm rotor to try with the taller gearing and see if there is improvement.

EMU, the voice you have here carries great weight. Please don't get involved with brushless rotor changing in motors at this scale. You have to but look at what that sort of shenanigans has caused and continues to cause in 1/10 scale. If it is prohibited at this scale now it will save hundreds of dollars individually and thousands across the scale World wide. You can bet it is already being done with an eye on giving or keeping an advantage at larger events like the one coming up in April.
