New tanker question

[Kvfan]

So I finally got a hl kv1s, it has all metal upgrades but does not have the torque to turn well in grass. I gathered upgrading to graupner 400 motors will help this, but the board I have is the rx13 I believe and can't handle them, and even if it did, I would want the proportional speed to control the faster motors. Is it possible to upgrade to a rx18 from the 13? I have seen conversion for the 14 to 18 but not from the 13.
also, would I need a new controller? I'd imagine so..

Thanks!

I think I read somewere that you have to replace everything, I think, I am not good at this type of thing. I buy the tank and snowproof it and thats all I do to my tank.

Hello KVfan , I did this upgrade on my cheap Tiger 1 - using an Rx 18 (with wires + plugs) , receiver and crystal type Tx from Dave 'forgebear'.

• Some soldering of wires is required but it is a simple swop .

The original HL gearboxes do struggle in the rough , * aftermarket 3 to 1 'boxes are worthwhile too , they have much more grunt yet still give the electrics an easier time and will transform the characteristics One of the best upgrades ever, I do it to all of mine now

He's rite there I've replaced my gearboxes with brass 4/1 gears from forgebear!! Check out his store he's got them in stock !; They give the tank much more torque and should make the battery last a bit longer plus the tank then moves like a real tank plus it takes the bite out of the super spin lol your tank will move a lot slower but it will be close to scale speed then!!!!!

Hello KV-1 owner

Changing the electronics from RX13 to RX18 isn't difficult and i've done it on the KV-1 and yes you need a new controller. You'll find it has all the fixing screw holes/poles etc to mount the newer stuff. You may struggle fitting the smoker, specially if you want smoke from the exhaust. If you look at my and Blimps KV-1 builds you see why.

If playing on grass you need to change to low ratio gearboxes (othen called 3:1) otherwise you'll struggle with turns unless you trim your lawn to 2mm. I have Asiatam 3:1 gearboxes in mine and recommend them good mix of speed/torque.

If you need any assistance just ask.

Thank you all so much for the info! It seems to becomes confusing looking up answers for the technical aspects of this hobby, so I greatly appreciate your help and input!

One other thing if you could,
I noticed where one place sales the rx18 with receiver board, I'm guessing if I'm upgrading the transmitter then this is necessary as well? I did not see a separate board in my current setup.

Thanks again

I think the Rx 18 package from Forgebear comes with it ( don't forget to get crystals )

Haha, good reminder.

As I'm looking......I do not see a 3:1 gearbox listed for kv-1
Is it the same as the m26,bulldog?
