SIG RASCAL 40
 

Help, I am looking for the motor mount (2 pieces of aluminum) for a Sig Rascal 46. Sig tells me they wont be available untill Sept 2012.

Any one have any???

Thanks for your help in advance.

Horizon sells a nice aluminum mount. Check them out.

Thanks for the info, but this Rascal takes a special motor mount.

I went to the Horizon site and looked at them and didnt find one that would work.

You can not use a regular motor mount directly to the firewall.

It needs to be mounted on a wood beam that is in place inside the cowl. You only have 1 option to mount your motor upside down.

It's just two flat strips of aluminum. You could make it easily yourself. Four holes drilled in each strip. The hole at each end is for screws to attach the metal strip to the wood beam. The two center holes are for attaching motor to strip. Attach aluminum strips to motor first, then place motor on wood beams and screw it down.

Yep, I knew how they mounted.

I got this ARF for a give away prize for one of our events. I didnt want to coble or have a make shift looking item on the new ARF.

That is why i was trying to get the orig parts from Sig. It seems that they have a issue with parts and replacement items for the kit and ARF's that they are selling.

It seems that when they took over the line they forgot about having replacement parts available[&o]

I also have a friend that needs a wing kit for his Sig Something special and it wont be available untill fall 2012.

I'll keep looking....

Thanks for the response.

Larry, Please don't let 2 missing small pieces of flat aluminum stock delay you from enjoying this fine flying model. No "cobled Up, make shift looking" parts will be necessary! These are about as basic, easy to fabricate parts as you will ever encounter. Go to any good local hardware or home improvement store and buy a length of 1/8" thick 1/2" wide aluminun stock. Cut 2 pieces 2 3/4" long, measure and mark for the 2 holes to mount the strap to the existing wooden motor mount. Drill the 2 holes. You now have what Sig supplied in the ARF kit. Follow the directions in the assembly manual for mounting the engine of your choice. Sig even gives you the original part dimensions in the parts list, 1/8" x 7/16" x 2 3/4". I made my replacements (the originals cracked after a while) 1/2" wide not 7/16" as there was room with my engine (OS 46 FX 2 stroke). So far the "new" ones have not cracked. This should take you about an hour or so to make including polishing them up before final assembly so they don't look "homemade". EZ-EZ-EZ, do it!

RE: SIG RASCAL 40
 

I do have the aluminum stock to make them and most 46 size engines have the same spacing for the motor mount holes.

Where the orig mounts slotted for the motor holes???

Also to save time, do you have the center hole measurement for the beam holes :)

Look at the photos in your assembly manual. Yes, the original straps had sloted holes so they could me moved in or out to fit different width engines. You know what engine is going into your airplane so sloting is not necessary if you measure, and drill accuractly. Drill the 2 holes for bolting the straps to the wooden mount beams just a little larger O. D. than the bolt shanks, then slot them if needed to get them into the desired mounting position (so you engine just fits between the straps). Then position your engine for and aft, mark and drill the 2 holes per side to mount the engine (again the holes just a little larger than the outside diameter of the engine mount bolt shanks). "Tweek the holes as needed to get everything to fit and line up. I believe the beams come pre drilled for the strap mount holes but anyway mine measure 2 3/8" apart. I also made my replacement straps 3" long, not 2 3/4" like the originals. this leaves plenty of meat on each end of the parts and there is plenty of room for the slightly longer mount straps. Not much extra room anywhere else in this engine bay as is's a tight fit everywhere else! Not the easiest engine instalation you will ever do, it requires patience.

RE: SIG RASCAL 40
 

As I stated in my post, this is going to be a give away prize at one of our events. So I wont know what motor will be used.

I can mill out the slotted holes without a issue, just wanted to know if they were slotted.

thanks for the measurements.

Larry, Oh, my bad! I didn't understand that you "got this ARF for a give away prize", I thought that YOU had won this plane at an event and wanted to assemble it for yourself. You said it right, I read it wrong! It all makes more sense now. Yes, slot the holes in the aluminum. Look to verify that the wooden beams are predrilled and match that dimension for spacing. The winner at your club's event will recieve a nice flying plane. Regards, 52Larry52

Is the Rascal 40 a good ARF to use a electric motor for power. Thanks Very Much.

Yes.

captinjohn, I just did a quick research on the Sig site to freshen my memory. The Rascal 40 became the Rascal 72 EG ARF, and it is now listed as "discontinued", so you can't order a new one from Sig. If you have access to an existing Rascal 72 EG ARF version I believe it would fly well with proper electric power as that version was designed for either electric or glo power and the Rascal is a good all around flying airplane. It's easy to take off, easy fly with no nasty habits, and easy to land. It likes to do all conventional non 3-D aerobatics, and looks good in the air. No wonder I also have a Rascal 110 in my hanger! I don't know why Sig dropped the Rascal 72!

I was recently looking for Rascal 72 parts and was informed by Sig retailer Sigmodels.com that the
Rascal 72 was undergoing redesign and would again become available.

52larry52, Thanks for the reply. Mine is new in box & would like to learn all I can to make a good electric aircraft with the Rascal 40. It is red & white. My hand has too heal more before I get to work on it...but please guys keep the data coming. Thanks Very Much John

oops, never mind, brain fade, mis-read some numbers...

Wow, that sounds good to me. I think I will like mine a lot !

Does anyone have a Rascal 40 that they fly near Brooksville Florida ? I got to find more RC clubs around here. Thanks John

If you are still looking for the metal motor mount pieces, there's a guy on RCG that is converting his to electric. You may want to contact him to see if he will sell his mounts. http://www.rcgroups.com/forums/showt...1713105&page=6
