Leo Best Posted April 20, 2015 Share Posted April 20, 2015 I crashed my firestorm into my little man's front wheel of his bike... Wiping him out.. He didn't see the funny side. But he was fine after a few tears of shock! Daddy what are you doing to me?? He noticed the front right wheel hanging on by the suspension arm alone. Both turnbuckles popped off the ball joints. I popped them back on with my fingers. I then noticed the ball joint that bolts into the suspension tower had been pulled out of its hole about 3mm. I also pushed it back in with my fingers. You can see in the PIC its not bolted in tight, thread has been stripped. Can I put a nut on the under side or should I replace the suspension tower? Same thing has happened to my blitz before. I put an m3 nut on the thread for a temporary fix. But I'd buy a new shock tower soon Quote Link to comment Share on other sites More sharing options...

Alex97 Posted April 20, 2015 Share Posted April 20, 2015 I see no reason why that wouldn't work. There isn't enough thread below for the nut to hold onto. You could put some thread lock on it to see if that works but it will never be as strong. Quote Link to comment Share on other sites More sharing options...
Goldigger Posted April 20, 2015 Share Posted April 20, 2015 Looks like a new shock tower then.. Have model sport got any longer shock springs, you guys can recommend? The stock ones seem a bit weak and as many people state on the short side.. Thanks.. Quote Link to comment Share on other sites More sharing options...

My Blitz did the same thing and i managed to put a nut on the underside no problem. Edited April 20, 2015 by RCMonkee 1 Quote Link to comment Share on other sites More sharing options...

A handy and fairly simple to do long term fix for things like this or other plastic parts are brass inserts. They can be had relatively cheap. I have a few different sizes I keep available. You just drill out the hole slightly smaller than the insert, tap it into place then put your screw back in as normal and as it screws into the insert there is pressure applied that slightly pushes the insert open and the knurled area digs into the plastic to hold it firmly in place.

scotty_b Posted April 20, 2015 Share Posted April 20, 2015 So my brushed motor smoked and died last night after being hammered by 2x Lipos. Time for brushless... Which combo should I buy, narrowed it down to either this: http://www.ebay.co.uk/itm/HOBBYWING-Combo-RC-Car-4000KV-Brushless-Motor-EZRUN-Waterproof-SC8-120A-ESC-/291007924670?pt=LH_DefaultDomain_3&hash=item43c16c89be or the standard Flux combo from Modelsport: http://www.modelsport.co.uk/hpi-flux-mmh-4000kv-brushless-motor/rc-car-products/380925 http://www.modelsport.co.uk/hpi-flux-emh-3s-brushless-esc/rc-car-products/380924 My Lipos are 2s 5000mah 40c. I'm a bit OCD and keeping everything one make looks like a winner but I don't want to rule out the Hobbywing combo if it's the better bet.

ostewart Posted April 20, 2015 Share Posted April 20, 2015 Alum shock towers ftw. They flex a lot less too, means the shocks do the work Quote Link to comment Share on other sites More sharing options...
Leo Best Posted April 20, 2015 Share Posted April 20, 2015 (edited) Hobbywing 10BL60 ESC and 3656 3800kv motor is a good combo. Also the stock flux combo is not bad but its expensive Edited April 20, 2015 by Leo Best 1 Quote Link to comment Share on other sites More sharing options...

They flex a lot less too, means the shocks do the work not really, your right they don't flex which means they don't have any 'give' and can bend.

scotty_b Posted April 20, 2015 Share Posted April 20, 2015 Looking at the specs of the SC8, at 120A it appears to be way over what's needed considering the standard Flux runs an 80a ESC. So I'm guessing the 4000kv motor that comes in the combo won't get the SC8 close to it's limit which is a good thing? Quote Link to comment Share on other sites More sharing options...
Relativenewbyseb Posted April 20, 2015 Share Posted April 20, 2015 Yeah and you can even use it later on if you want to put it in an 8th scale buggy for example... I have the Sc8 and 3800kv 3656 motor and no heat issues with standard 19/87 and 3s Gps'd it at 50 [emoji106] Quote Link to comment Share on other sites More sharing options...
