mtbkym01 4248 Posted March 6, 2012 I hear and read that ratchet trims are required to operate Tamiya's MFU in the truck kits. This is the radio I'm considering (cheap, but should do the job I think) HK 2.4 4ch Anyone tried these? My kit (Aeromax) should be here soon, haven't ordered anything else yet, it seems I'm stuck with Tamiya's MFU as others like servonaut (which I believe are meant to be superior) seem quite unobtainable to Australia (compared to Europe anyway).

Skottoman 306 Posted March 6, 2012 I'd be careful with that 2.4... even if it has ratchet trims you must make sure they are analog... The Tamiya site specifically says not to use 2.4's with the MFU. I even went as far as to buy and install a Futaba 4YF FHSS 2.4 system in my knight hauler with MFU, and had to remove it. It just wouldn't work properly!!! I ended up buying the FM version of the Futaba 4YF, and all problems solved. It sux it has an antenna, but at least everything works perfectly! Although I had to order a spring and arm to make the left stick self centering instead of ratcheting for airplane throttle. Here's some information from Tamiyausa SEPARATELY REQUIRED ITEMS 4-channel self-neutral stick-type transmitter equipped with slide trim and self-neutral feature for optimum performance. (Futaba Attack 4WD recommended) Tamiya recommends the Futaba Attack 4WD (T4VWD/FP-R114H) because it has a self- neutral feature. Other 4-channel transmitters made by Futaba, JR Propo, and Acoms can be used with the MFC-02, but operations may not be as smooth as they may lack the self-neutral feature and connectors may not be compatible. As for transmitters from other makers, while it may be possible to use them, please note that there may be instances where they may not be able to operate all of the MFC-02's functions. 4-channel receiver. 2 servos. SPECIAL NOTES Do not use together with ITEM# 53909 TLU-01 or ITEM# 53937 TLU-02. MFC-02 is compatible with the Type 540 motor only. Please avoid installing other motors. MFC-02 cannot be operated with 2-channel or 3-channel transmitters/receivers. MFC-02 is not compatible with PCM type receivers, multi-channel receivers, and older receivers made by Sanwa (identifiable by their black cases). Not Compatible with 2.4ghz systems or others that have digital trim Share this post Link to post Share on other sites
BRELs 0 Posted March 7, 2012 I use a Planet T5 and T7 2.4 gig radio with my trucks and tanks the planet radios have analogue trims and I have never had any control issues with the radio, the receivers on the other hand are OK but I would not use the planet R7M receiver with a truck or a tank because the throttle channel defaults to a wide open setting causing the truck or tank to runaway, in my latest project I am using seven channels on a roll on/off hook lift container truck and use a R6M to run the MFC and a R7M to control the seventh channel for the fore and aft movement of the container on the trucks back prior to unloading it of the truck Share this post Link to post Share on other sites

I currently use that radio on my highlift crawler, I once unplugged it and put it into my Knight Hauler and it worked fine. The only thing that annoyed me was you would have to make a custom shift gate because of the stick dimensions, and the lack of ratchet or spring on one of the sticks, would be an easy fix though.

I'm assuming your Knight Hauler had the MFU in it? Share this post Link to post Share on other sites
berman 5317 Posted March 11, 2012 I'm assuming your Knight Hauler had the MFU in it? Yeah just swapped the receiver in, was doing a fault diagnosis in this thread: http://www.tamiyaclub.com/forum/index.php?...c=54543&hl= ^As a matter of course^ I have since swapped the stock silvercan out for a 55t integy which I borrowed from a mate, and it doesn't play up anymore, so still using the factory 4VWD Share this post Link to post Share on other sites
