Title: Profile Electric Motor Mount
Post by: petermick on March 14, 2017, 03:50:23 PM
Last week at VSC I purchased a beautifully finished Francherized Twister from Bob Hazel.  Bob had completed the model with an OS 25 mounted on it.  Because I have gone over to electric flying I purchased the plane without the engine and my intention is to convert it to electric.  I have never built or converted a profile.  Doing a search on the All Amped Up files I found a build thread from Christ Rigotti dated 2009 which shows an aluminum profile motor mount.  I believe Archie Adamisin suggested in this thread that this mount could possibly be produced for sale.  I am wondering if this was ever done and if so where can it be purchased.

Christ, if this was a one only piece do you have a drawing of it.

Thanks

Pete,
Don't go the aluminum mount.  That was a long time ago and a 1 off.

Here is where I modified a Sig Primary Force for electric.  Perhaps you can glean some good info off that.

I have done other electric profiles but I think they were electric from the get-go.  I'll look and see.

you might also contact Pat Johnston, he has been laser cutting some really cool battery holder box motor mount assemblies that work a treat

Hi Peter

You are going to need a battery box too, I really like the idea of integrating the firewall with the battery box because supports around the perimeter and keeps battery space clear.  Shown below is the Brodak BH-1938, shown installed in a Brodak Mauler Profile. Basically you build the box, cut a 1.75" x 7" slot in the fuselage and install the box.  The motor and battery are also centered on the fuselage, battery installed from the INBOARD side.  Not too hard a conversion even on a built bird.

Hard to beat at $7.99.  Link to the item: http://brodak.com/electric-accessories-1/conversion-kits/warbird-electric-conversion.html

Christ, Mark and Dennis,

I want to thank the three of you for your very helpful responses. 

Christ, I have a few questions regarding your 2013 building thread. 1) Is the motor only mounted on the front and not supported on the rear?  2) I noticed you used a Hubin timer.  Where did you mount the red start button that usually accompanies a Hubin timer?  3) Where did you mount the arming plug?

Please forgive me if I missed any of these items in your thread.

Pete

Motorman,

I'm sure your post was very helpful, unfortunately it never showed up on the thread I started.

Peter,

We have converted several profiles to electric using 3/8 or 1/2" angle aluminum bought from Lowe's or Home Depot.  It's a rear mount set up, got the idea from Will DeMauro, he's had pics of this conversion in some of his past columns in Stunt News.  I found a couple of pics.  This first one is before the mounts were finished out to look nicer.  The second was an old profile I picked up from Allen for Ben.

My sincerest apology for my oversight.  This was a senior brain fart.

Pete:
1) Yes, front mounted only.
2) The Hubin timer (FM9 IIRC) I used has the start button on the timer.  It is not separate from the timer.
3) No arming plug needed.  I simply disconnect the battery from the ESC.  Everything is out in the open.
