I promise I’ll post high resolution photos after I get it outside.

It runs well, next will be some thick three tone camo and some weathering, plus adding all the hand tools and other details.

[Robert E Morey]

Beautiful. Awesome looking rig. Will look even better with more details and weathering!
Best regards,
B

Thank you Bob, it is a really nice model and it’s running pretty well for the first day! I don’t hold back with my driving and breaking in the Famo is no different. Here is a demonstration video but I will ad the disclaimer that it is very hard to drive one handed because you have to coordinate the two sticks for turning hard. I sort of used my pinky and forefinger on the transmitter while filming with my other hand here to show off the turning radius, which is really good surprisingly. I’m definitely having fun now.

Nice test drive Brian.
Mybe you'll grinding the chains teeth, than the track will run better
I did this on my 251 and Famo. the result was awesome.

I might. How much material did you take off the guide teeth?

[florian rudolf]

About 1,7mm on the top on bouth sides. starting in the middle of the tooth.

Great clip Brian, nice build and well steered.

I never could get to grips with my Half track. For such a large model, you made it look easy.

Though I think I'd be looking at ways to loose the track noise before something happens.

Thank you John, I’m not quite all the way through my first battery and I just blew out the linear actuator. Still getting used to the coordinated turns I guess. The tracks are settling in but still a little sketchy. Might try grinding down the super thick teeth. Are the tracks same as the other halfsies 251 and 7?

Note that an extra 30 lbs on the nose damaged the linear actuator.

[florian rudolf]

Thats true, I had massiv problems wist the tracks at my 251. Grind down the tooth side top, and every thing is rigth. the same on the Famo.

[John Clarke]

The famo track link is certainly different to the 7's which had no rubber pad and was completely solid. I'm not sure about the 251, but driving wise you certainly seem to have the touch with the steering. If recall it is possible to use a slave parameter on the R/C so that single stick control is possible, but that became problematic when reversing.
New tech on R/C might over come this. But I'm sure many would just enjoy the involvement, practice and concentration needed to display the skills driving such a fine beast
I remember that the sprockets on the 7 could take beating if not setup correctly. Mine seemed to be ok but I never seemed to be able to perform tight turns like you have.
I hate the sound of crunchy tracks, it's going to happen with new components but like the Armortek Chieftain demo, it's something that needs to be addressed
As for the extra weight on the front, I'd have to remove it and lock it up in the house, They'll respect you for it, if they don't, tuff!
(I like children, but I couldn't eat a whole one)

Hi John,
I think the 7 is having the same track links licke the 251. Maybe nearly the same.
the problem is the stearing from the track. One chain teth, a smal track, and a long way round. So much options to move sideways in turns.
Some of my 251 tracklings broke bevore I edit the chain teeth.

[John Clarke]

Hi Brian & Florian, I don't own the 7 anymore, but I was aware of the power on the tracks, they would drag it sideways if I let it.
I cannot really comment on the 251, because I never drove the model, the single motor drive and differential would probably be a little more forgiving than direct drive. But powerful forces exist within, so I'd be always looking for smooth transmissions. Tension too tight, too loose and track mods all come with experience and the only way that happens is to read a bit and play with the thing.
Preferably without a child on the bonnet and wellies marks all over your lovely paint work, unless he's perfecting the paratrooper roll for a future insurance claim.

[florian rudolf]

You're right. Wellies have no place on a model ...
Despite the differential in the 251, the forces are enormous. During the first test drives in the field, I had 2 tracklinks brocken on approx. 100m.
Ok at the Famo not yet, but I was also prepared.
The forces are much greater. I wouldn't reduce the chain to 0 when steering either. Wasn't with the original either and there was a reason for that.
