Perhaps you could do some more of the breaking-in of the engine. Curious to know the performance. Crashed_1 got his already.
I'm not sure how much I posted here before I went on Holiday, but the FX is wild!!!! I was running at about 85C or 90C and it was faster than the 2106 tuned!!!! This thing is a monster
I've got it running at 100C just before I went on hols and will take it upto 110C when I get back to the track. Not sure what the max temp is on this - with it having ceramic bearings.

Crashed: you done any run-in yet? Have you got the cermic bearing version?

Cheers, Mark.

PS: I will also record the WAV file for you D - do you want a fly past or an idle?

Bro, serpent new alu. middle shaft mount is perfect answer from the snake.
Im using 3rc upper 1way holder and I can loosen 2 notch (eccentric tensioner) comparing with the composite mid shaft mount with same old belt.
The clearance between battery holder is not scarry anymore.
1 more important thing, bearing fit is truly h7 class perfect!!

Of course it's the ceramic bearing + black coated crankshaft version. Nothing but the best for him.

He just go it though. I don't think he ran it in yet. Wanted to persuade him to let me run it in for him this weekend since he'll be off to meet Charlize Theron in SA for about a week or so.

Have I missed something whilst I was away: where can I see the new middle shaft mount?

Cheers, Mark.

Cool. Glad to know that and thanks for the info bro. Yesterday, I did the old Impulse / 705 trick. Put some shims (0.5 mm) under the composite mid bearing block to tilt it backwards to tighten the front belt.

I thought I would end up with a loose middle belt since the mid bearing block was tilted but after straightening the chassis a little in the center (took a long time), the middle belt is OK and I don't need to put the tensioner to max downward to get rid of the middle belt slag. The side tensioner is just slightly below the top position.

Do you have the problem of the chassis bending in the middle where the X bar radio tray support is and also around the part where the engine is mounted?

Ach tell him not to waste his time - she's not as good as she is cracked-up to be

I believe the aluminum mid bearing block just surfaced about a week or two ago in some LHSs. Not out on mytsn yet. Aluminum silver finish.

Fukuda looked great in the 1:8th, but Mike looked better in the 1:10th.

Go out and get your copy

Cheers, Mark.
I have already watched the DVD. Swauger 1:8th was just fast but not as fast as Raph, Josh or Fukuda. The way he was driving on the stand was quite funny ... But his 1:10th was very fast and expectly long straight ......I just wonder what the engine he used ?

I think it was the Mugen JP X12 engine. Not the newer JP FX.

I liked Ray's comment: "Eyes on - eyes off" Pretty much summed up what we saw Great DVD!

Even with the new chasis, I still have some 0.5-1mm kick up if front, strengthen front belt is making it worst.
After hard impact, usually the notch on the X bracket will broke.
And this will make chasis bend(upward) more.
In 705, X braket is aluminium so the carbon stiffener is the one that will broke.
Just like shock shaft game, which one you choose, broken shaft or lower ball end pop off. Adding more play on top of shock mounting definetely reduce the risk.
