MItchell 45xx battery/radio control
Posted: Sat Oct 05, 2019 8:49 am
Hi folks,
During our demo last weekend at Scaleforum I mentioned to a few people that my next mission was to build a locomotive with a 4v motor and radio control. Mr Scannell found some motors on eBay we think intended for electric razors and both of us ordered some, they're about £2 each. The particular interest to me with these motors is that they have a 1.5mm shaft and m2 fixing holes correctly spaced for High Level gearboxes. I like to keep things simple...
I started the project this week. I'm building a Mitchell 45xx, somewhat larger and roomier than the 517 I was demonstrating at the weekend, but this is a fairly chunky motor. I have built some of the body first, mainly to ensure I can fit everything. Some photos attached...
Motor and gearbox assembly, this is a HL LoadHauler gearbox:
Battery, 750mah, 3.7v, length 44mm, diameter 14mm, lipo rechargeable with protection circuit. This is the same type of battery that I have in the 517 that I was demonstrating last weekend. It was running pretty much constantly up and down our little test track from 9am to 4.30pm without needing to be recharged, and actually still has power now! The Deltang receiver is shown here also.
Some surgery needed to the front of the tanks to allow for the battery to be inserted into the smokebox:
Looks like it will all fit!
I'll be working on this all weekend so as long as Netflix doesn't get in the way I'll be posting some progress updates from time to time...
Thank you! Nick
