That's quite funny as I was just looking into this. Had to google to find out where it was. Assuming I'm looking at the rotating quadrant with what appears to be a nut and spring washer, it doesn't appear to be wound all the way in. I just cant remember seeing my son hit anything that hard so as to cause the horn to jar. Let alone enough to cause the horn to jar and strip the threads on the screw. I can't see how it could happen under any circumstances to be honest. Not if it was tightly fastened to the splined servo shaft with the screw. And I suspect it wasn't.

Sent from my ONEPLUS A5010 using Tapatalk Whoops, I'm sure it won't be the last. Did he hit it hard or just got unlucky and caught it at a bad angle? Suspension arms come in pairs so at least now you'll have a spare. Edited February 28, 2018 by everclear1984 Quote Link to comment Share on other sites More sharing options...
BoutTime Posted February 28, 2018 Share Posted February 28, 2018 Is it worth going for the graphite version? Quote Link to comment Share on other sites More sharing options...
collective itch Posted February 28, 2018 Share Posted February 28, 2018 no, the graphite versions will break quicker. FairPlay, must be the cold, ive battered the snot out of my firestorms, and never managed that. 1 Quote Link to comment Share on other sites More sharing options...
JamboV6 Posted February 28, 2018 Share Posted February 28, 2018 Bare in mind it's -5c outside, plastic gets brittle. I've killed many servos over my years, normally the gears strip before the spline so I'd definitely say it has been loose from day one to allow it to strip. 1 Quote Link to comment Share on other sites More sharing options...
BoutTime Posted February 28, 2018 Share Posted February 28, 2018 Yep...perhaps the cold. It's interesting because my eldest really smashed the wall when the arm broke. I checked his servo shaft and horn and it appears to be perfectly fine. Just hoping the gears are. So the horn on the other car was definitely already loose. x3 off road rc cars delivered yesterday, x2 are now literally off the road. Lipos arrived earlier. Will re-terminate the connectors in the morning and have a blip before work on Friday. 1 Quote Link to comment Share on other sites More sharing options...

But I have managed to re-solder (very badly) one of the LiPos and I've just taken the car for a spin outside the house. Well F~*k me! I wasn't expecting that. I can't believe the difference in speed and acceleration. My eldest came out to watch - the one who hit the wall earlier today in his - and he even asked for a bloody go. No chance I told him. I'm glad I bought them NiMH packs, the LiPos would not be a good idea for them at this time. I just didn't expect that kind of performance and I'm glad I didn't go brushless. I'm looking forward to getting all the cars up and running and getting out in the open somewhere. Jesus wept! Quote Link to comment Share on other sites More sharing options...
everclear1984 Posted February 28, 2018 Share Posted February 28, 2018 Once you get it out in the open you'll soon want to go brushless I'm glad you're enjoying yours, it's a shame the kids ones are out of action for now. 1 Quote Link to comment Share on other sites More sharing options...

stretch Posted March 1, 2018 Author Share Posted March 1, 2018 You not using those tamiya connectors with lipo are you? They are very low current and can melt someone did mention it a few posts back. Do not use them. Quote Link to comment Share on other sites More sharing options...

BoutTime Posted March 1, 2018 Share Posted March 1, 2018 Right I've already ordered those adapters. So I've just ordered some HXT connectors to re-terminate the ESC.It's daft HPI market the car as LiPo ready yet use connectors that can't cope with a LiPo battery.I'm assuming the motor will be ok? Was advised not to use LiPos on s brushed motor.Sent from my ONEPLUS A5010 using Tapatalk Quote Link to comment Share on other sites More sharing options...

Sent from my ONEPLUS A5010 using Tapatalk They just do it for marketing reasons. They can say it’s lipo ready because the ESC has a low voltage cutoff. They know that most NIMH batteries have a Tamiya connector and that connector is familiar to a lot of people. Quote Link to comment Share on other sites More sharing options...

Will just have to resolder the battery with the XT60 I put on it.[emoji849]Sent from my ONEPLUS A5010 using Tapatalk Quote Link to comment Share on other sites More sharing options...

BoutTime Posted March 1, 2018 Share Posted March 1, 2018 Ok so the servo is in and working great. But it will probably be coming out again. I probably should have gone with my hunch but would be interested on the thoughts of everyone else.... I was told on the phone to centre the servo to line up the horn vertically. The problem is when the steering is centred on all three cars the horn is actually off centre itself. So my intent was to install one tooth from 12 o'clock. But I didn't. I was hoping there would be enough play in the servo adaptors to slide the servo sideways to compensate. Now it's all in, to get the car to run straight I have to apply quite a bit of trim on the transmitter. And the transmitter will trim the wheels much more one way compared to the other. I just wondered what everyone else does when replacing a servo on a Firestorm. Cheers. Quote Link to comment Share on other sites More sharing options...
