Has anyone built the DB Sport and Scale Corben Baby Ace for electric power?

If so, where did you put the battery and how did you get access to it?

I plan to use a 3S 3350 LIPO and have tried all sorts of possibilities but I find snags with all of them so any help will be gratefully received.

Thanks, Dave

Well nobody has replied yet....... ........ One idea you might consider is one that has been used by many people on different models ( Wot4, SLEC FUN FLY etc) is to use a removeable ply plate with a tongue that slots into motor bulkhead and a bolt at the other end to secure into a captive nut.  Battery is held to this removeable ply carrier plate with velcro straps. Ply plate goes in at an angle from underneath, so the access hatch is underneath. It might mean connecting up when model is inverted - maybe needing a simple stand - but it saves hacking the cowl around.  This method is shown on Chriss Foss'  website and maybe he originated the method.

Thanks very much KC.

My main worry had been securing the battery once it has been inserted and your idea overcomes that.

There is a hatch on the underside that I can make removable and it will be no problem to have the model inverted while I insert the battery on its ply plate - I already have to do this on my Riot.

I will now go and explore this possibility.

Thanks again, Dave

The two possibieways of fixing the Lipos to ply are

cable ties and cutting away each time and replacing.( might be more secure and cable ties are cheap ) Or use a separate ply plate for each Lipo.

Velcro on battery and on ply together with velcro strap right around - belt and braces. Ply should be treated with a coating of epoxy etc and left to harden before using self adhesive Velcro. ( Self adhesive easily pulls off if the surface is not smooth)

I think I must be misunderstanding you. you are not suggesting fastening the Lipo in place with cable ties and then cutting them to release the Lipo?

I worry about anything sharp near my lipos.I like to hold them in a soft manner, typically with a velcro strip and Velcro broad cable straps, as the braces to the velcro strip belt.

Well it would appear that is the way it's shown on the Wot4 electric modification! But the cable ties would seem to go out at an angle and a large gap would be available to get cutters in without touching the Lipo. ( ply plate is wider than lipo and it is notched to take cable ties ) But Erfolg is right to warn about any possibility of cutting into a Lipo and causing a short circuit which would be dangerous.

However all my own models are fixed with both Velcro patches and Velcro ties ( 2 for a 4S3000 ) which has worked well when mounted above the ply ( the method for Wot4 and possibly the Corben Super needs the Lipo to 'hang' underneath the ply which might mean cables ties are more secure)
