ericrw Posted February 18, 2010 Share Posted February 18, 2010 I am wanting to upgrade my minimag power train. At present it is powered by the standard Multiplex Permax 480 motor. I've bought an Overlander Thumper V2 Brushless Motor. The Thumper is much smaller in diameter and fitting it to the Minimag as proved to be a problem ! Has anyone out there overcome this problem and if so I would appreciate some know how and if it's accompanied by a sketch or photo, that would be great ? Thanks Eric.

It would be easier to get advice if you could post a pic of the existing firewall and mount so people can consider what could be done thanks.

Romeo Whisky Posted February 18, 2010 Share Posted February 18, 2010 You've heard the phrase:- "If I were going there I wouldn't start from here" ?? As you know, the standard MiniMag motor mount is designed for front mounting, and the standard Permax motor is quite heavy. The easiest btrushless upgrade is therefore to get a 400 size inrunner which is a straight swap fro the Permax and the only other issue is to switch to a brushless ESC. I used a BM400 1800Kv with a 7x5 APC prop, but there are cheaper inrunner setups from such as GiantCod or 4-Max so you can go up to 2200Kv with a 6x4 prop. If you use a lightweight outrunner, you will need extra lead up front to balance. I have friends who have even had problems retro-fitting the Multiplex brushless power-train.Edited By Romeo Whisky on 18/02/2010 12:52:17 Quote Link to comment Share on other sites More sharing options...

Romeo Whisky Posted February 18, 2010 Share Posted February 18, 2010 Hi Eric, The BM400 1800Kv was from Overlander, but I have not seen them on their web-site lately. However I have seen them advertised quite recently at Gliders UK. http://www.gliders.uk.com/ It has been a great little motor and suits the Mini-Mag ideally with a 7x5 prop. I have quite a large "air force" these days, but I still fly the MiniMag on nearly every trip to the field and take it on holiday with me every year. It is just a great little model on this power setup. If I ever bust it, I would have to replace it. RW Quote Link to comment Share on other sites More sharing options...
ericrw Posted February 19, 2010 Author Share Posted February 19, 2010 Hi Romeo, Gliders have just informed me that the BM400 is now discontinued. Thanks, Eric. Quote Link to comment Share on other sites More sharing options...
Romeo Whisky Posted February 19, 2010 Share Posted February 19, 2010 Hi Eric, I was looking on Giant Cod and 4-Max web sites this morning and one of them (??) had a 1900Kv inrunner which looked as if it might fit the bill. Both sites offer 400 size 2200Kv inrunners too, and these would also be fine with a 6x4 prop. A pal of mine has this set up and it works fine.
