Model Forum / Radio Controlled / Land Models / September 2006The Revo and some ramblings
Seriously, I'm beginning to think this thing is invincible! It just takes abuse day in, day out, no matter what I do it refuses to break in any way - I just soaks it up and asks for more! Brilliant! I think the motor is starting to show a few signs of wear (I notice stupidly short recommendations from Traxxas - change the rod at 3 gallons or when you change the P&L - whichever comes first! So the P&L might not last 3 gallons!). This is to be expected I suppose, I've thrown quite a bit of fuel through it, and I dunno how much it had already had through, but it's ok for now, just won't idle for more than about 10 seconds (a problem I could probably fix with a little tuning....). A few mods have arrived, scored a custom painted shell of eBay for £10 inc postage, and the guy very generously threw in another bright orange shell for free, also unused! Also, another pair of red pushrods to go on the front are on the way, along with a new manifold (the one I have now is a bit damaged) that is shiney adonised silver, and a resonator pipe - which Trx claim gives me 20% more power below 15krpm and 10% more power above - I'll let you know how that goes. Went with a mate today on a short road trip to Ripon (60 miles away) to collect another Revo he just bought on eBay for £220ukp with RB323 motor fitted (also included a couple of shells, and the Trx 2.5R motor as well and a load of other guff) - by hell that thing shifts. We were running it VERY rich today, and it was blisteringly fast - looking forward to leaning that right off... Pics and vids to follow naturally. Sold the STS off, as I couldn't be bothered to fight with it anymore, and put my old, slightly hammered K4.6 into the Savage again - it ran nicely, till the screws holding the engine plate in came loose and I somehow managed to half knacker the Robinson Racing clutchbell! Although the RR Spur gear was ok (it just ate the CB....). Dunno how I acheived that to be honest. Anyhoo - what has everyone else been up to RC related of late?

That TM323 really screams in the revo, doesn't it? My kid has one,, , wheelie machine. . . I got a hyper7 off ebay a few weeks ago, and put the novarossi .28 in it, , it's the engine I had in the MGT, makes it quick, fast, and mega fun. Super easy engine to tune. Got ahold of an RB TM728 for the MGT, , , ,which is hella fast, , but still won't make that pig wheelie, not sure what that will take. . The 728 runs great, , but gave me a bit of a scare, , ,one of my kid's friends was driving it (I was driving the Hyper 7), and all at once it had NO compression. . .plug was tight, engine not overly hot, no leaking around head. . even went as far as to look up the price of a P&S, , ,yikes, , $135 . . .Did a compression test with ARO in the cylinder, , ,it all leaked out THROUGH the plug, swapped it out and got all it's pop back. In the meantime, the kid got a MBX off ebay, , that we've been less than happy with. To start, the seller listed flat rate for priority mail, , then sent it "media mail" or something like that. instead of taking 3 days, it took almost 3 weeks. Came with a force .26 that the seller said "screams", , ,ok, maybe if you mean the compression SCREAMING out the cylinder past the piston. Kinda guessed the engine would be worn because we got the whole thing RTR for about $150.00., so I pretty much expected it to be not so good, but this is a bit excessive. This thing has the 2-speed center gearbox upgrade. . .not liking it AT ALL. inconsistant shifts, when it actually does, , ,and the gear mesh, as someone here pointed out, , is a bit weird. It doesn't help that I shoehorned an associated .28 (from the MGT) in it, but there is still a bit of weirdness, much of it I think is the trans. The kid has a center diff on it's way. . . Also, got some diff oil (1,3,&10k) to replace the 120,000k stuff in the hyper, , gotta go do that now. ..

The kid has a center diff on it's way. . . I had a Protech badged mBX (exactly the same buggy, just sold in this country as a Protech). Don't be too upset about the lack of compression on the Force, they're crap anyway :-). Quite a solid buggy though, does the job well. > Also, got some diff oil (1,3,&10k) to replace the 120,000k stuff in > the hyper, , gotta go do that now. ..

Not a huge amount, my Tamiya Thunder Nitro buggy and TT DT-10 have been collecting dust since I got the MTA-4 .28. I love it so much, and whilst I can only compare it to the first two cars I mentioned, it RIPS them apart in terms of speed, jumps and general bashibility. I have taken it to the local CONCRETE skatepark a few times, and gone for some wicked jumps. I have had some VERY VERY nasty landings, as in, head first into concrete and about 6 vertical flips across solid stone ground - not even a dent so far. I did manage to break the "stick attached between the front suspension and front wheel" after thinking I was in reverse and going straight into a solid wall. £6.99 and 20 minutes, all fixed. Took it out a few nights ago to race my friends DT-10. We crashed. His car suffered two broken front suspensions, and the very thin stick which moves when you accelerate snapped too. My truck just carried on laughing its arse off :) His MTA-4 will arrive today or tomorrow, can't wait to have some real battles!!! Gary. > Anyhoo - what has everyone else been up to RC related of late? Beating the tar out of my Tmaxx 3.3 which also seems industructable (except for motor mounts and hinge pins.. lol). Hitting firepits made out of brick at full speed.. well, that'll break a hingepin. But nothing else! Landing on the lid after 8 foot jumps. That tends to break motor mounts. Nothing else! :) Got it tuned pretty good now. Wheelies are inconsistent... not sure what's up with that. I'm just gonna drive it now instead of trying to get the super perfect tune. :) Gone through 1.75 gallons so far. Lasted longer than my 1st when the rod went at 1.5 gallons.... ugh.. that was a mess. Too many high speed runs in the grass I guess.. lol! > Got it tuned pretty good now. Wheelies are inconsistent... not sure > what's up with that. Probably a clutch/clutchbell issue, ,, The revo 2.5 had a fairly weenie clutch >>Got it tuned pretty good now.

Didn't seem to help much. Maybe I should have sanded the inside of the clutch bell while I had it out.. forgot. :) |
