  1. cheers alvinlwh Just been looking through the 5kg servo provided with the first model and looks like a cheapo, it does't even have any branding on the case. Nice to hear from Orkney. I live in Essex now but lived most of my life in North of Scotland. Still have a lot friends in Wick/Thurso and Kirkwall. J
  2. Thanks all for the comments / feedback. Apologies for the delay in responding. I'm using an Absima CR3P on my original pumpkin and I've set the endpoints to the steering stops before it pushes against the chassis. On the problem pumpkin I only have an Absima CR2 transmitter where you can't adjust the end points. I set up the end points for the functioning pumpkin then marked out the turning circle on concrete and matched it with the second pumpkin where I can't limit the end points. I reduced the servo throw to the turning circles were the same and neither pumpkin steering makes contact with the chassis. The company I bought this second pumpkin from are still selling with 15kg servos as standard which from what you're all saving does seem crazy especially if you've had good service from a 3/4kg servo. I love the metal plate upgrade, looks a great solution! I have a new chassis on its way. Any recommendations for a particular servo? I have had a few steering servos in the past that have irritated me due to the electrical chatter and never sitting still.
  3. Hi. Newbie here probably doing something stupid but need a little advice. I have 2 midnight pumpkins, the first I built last year (lockdown project) and can 100% stock with 5kg steering servo and standard servo saver as supplied in the kit. This model has been great fun on rough ground, tarmac and even drifting on gravel. the steering servo is great smooth, quiet with no electrical chatter at all. No issues with this pumpkin apart from the body mounts. I have just built one for a friend and this pumpkin came with a 15kg metal geared steering servo in the box. After around 2 minutes of running on a smooth concrete surface I lost all steering. When applying the brakes at speed these pumpkins always do a bit of a handbrake turn which will obviously put some strain on the servo but this has never been a problem on my original pumpkin. I popped the body off and the steering mounts have both cracked leaving the steering servo flopping around. This is the second time this has happened and I have replaced the chassis already when the previous one broken. No idea what's gone wrong here. Is the steering servo too powerful or has the servo saver failed? Should I be using the Tamiya high torque 51000 servo saver or should I pick up a 5kg servo despite and remove the 15kg supplied with the kit? I checked the chassis during assembly and it was solid with no cracks. Any help much appreciated. I've loved my own pumpkin but feeling bad for a friend who's pumpkin is sat their looking sorry for itself. Annoying thing about the chassis being wrecked is you have to virtually rebuild from scratch! Any help much appreciated!
