Chris Stevenson Posted August 7, 2015 Share Posted August 7, 2015 I am planning my winter build project and have settled on the Auster as there are lots of build blogs to follow. I cannot find any with electric power and am looking for help in how to provide access for battery changes. My previous building experiences have all been "as per plan" so unsure how to change it. I have read the posts on BEB's Chipmunk conversion and something along those lines seems feasible. Has anyone been there and done it already?

Phil 9 Posted August 7, 2015 Share Posted August 7, 2015 this might help with motor selection **LINK** so it has been thought about by some one at least. Looking at photos of finished models I can see your problem as there is not an obvious area for a battery hatch. it looks to me it may have to go in through the bottom Try an email to DB sport and scale that might have some info good luck with the project Edited By Phil 9 on 07/08/2015 08:35:36 Quote Link to comment Share on other sites More sharing options...
Dave Hopkin Posted August 7, 2015 Share Posted August 7, 2015 Might also be worth looking at how comparable sized Cubs have accomodated the battery as they are quite a similar shape nose and cabin....... Quote Link to comment Share on other sites More sharing options...
Tony Bennett Posted August 7, 2015 Share Posted August 7, 2015 can you not make a top opening hatch something like this. Quote Link to comment Share on other sites More sharing options...
Chris Stevenson Posted August 7, 2015 Author Share Posted August 7, 2015 Thanks Phil, I have emailed Richard at DB and he is aware that others have converted the Auster but doesn't know how they overcame the access issue. He suggested the forum so hopefully someone will have done it. I think bottom access is probably best. Quote Link to comment Share on other sites More sharing options...
Chris Stevenson Posted August 7, 2015 Author Share Posted August 7, 2015 I could do something similar Tony and make a balsa cowl instead of the one supplied. Thanks for the suggestion and photo. Quote Link to comment Share on other sites More sharing options...
Peter Groves Posted December 17, 2015 Share Posted December 17, 2015 Hi, having just received my Auster kit from DB I have been studying the same issues. My thoughts, at the moment, are to omit the existing fuel tank holder and replace it with a battery box angled from the bottom ( access through a hatch in the fibre glass cowl, and angled upwards towards the centre of the cockpit at approx 45 degrees and construct a battery box. The 6 cell battery could be located on a ply slider as in my Wots Wot. It would mean enlarging the bottom access through the first former to give clearance but a strengthening rib either side should compensate. Any opinions gratefully received, PS I intend using possibly an E flyte 60 Quote Link to comment Share on other sites More sharing options...
Allan Bennett Posted December 18, 2015 Share Posted December 18, 2015 With my 1/5 scale DB Cub I've installed a battery box which is accessed through the front of the cowl -- say roughly where the rectangular holes are in Tony Bennett's post above -- and goes back horizontally through the firewall to give enough length for my 3S 3900mAh LiPo (originally two 7-cell NiMh packs in series). I cut an access hatch in the fibreglass cowl, and hinged it. Since access to the battery is impeded by the prop, I've installed a safety plug in the side of the cowl so I can isolate the battery before trying to open the hatch. Edit: Here's a photo.

ascot Posted January 1, 2019 Share Posted January 1, 2019 What engine do you intend to use and battery size I am contemplating a 50 and 4cell but will still have to do some research. What mod did you do to mount the motor Quote Link to comment Share on other sites More sharing options...
Chris Stevenson Posted January 1, 2019 Author Share Posted January 1, 2019 I’m sorry but I am unable to help as I decided to stick with ic and fitted an OS 95 and didn’t pursue the electric route. I would be interested to hear how it goes if you do go electric. Quote Link to comment Share on other sites More sharing options...

kc Posted January 1, 2019 Share Posted January 1, 2019 The DB website has a link to 4Max for a suitable electric setup. Mentions a motor mount too. Quote Link to comment Share on other sites More sharing options...
