I couldnít find door cylinders online to fit my inner gear door needs so I had Sierra Giant Scale make me a set: 1/2X2 inch. Theyíre perfect. Darrell at Sierra does beautiful work.

if you look closely you can see where I mounted this cylinder first. It was too close to the hingline allowing flex. Bottom picture shows how new position results in much better triangulation.

After a bunch of deliberation I decided to bolt the motor mount on instead of gluing. I attached servos and ignition to mount so the whole assembly is removable as a unit.

So, engine is installed, cowl is mounted and baffling is installed. Cowl has 5 bolts holding it on: two flush bolts on bottom and three bolts that bolt in from the INSIDE of fuselage for invisible mounting.

Well, after 4 years the day has finally arrived. Itís time to close the hole in the fuselage for the smaller canopy. I have been dreading this literally for years! Didnít really know how to approach it but I think I figured it out: I used some very nice 1/32 basswood sheet to back up the hole. I covered this wood with release tape then glued it in place.

Then I used a light filler to fair the whole mess in to fuselage height. After sanding to blend in I covered with my green adhesive release film. I have used this process several times now and it has never failed to produce great results.

I decided on a 7 inch spinner. Itís a compromise of scale looks and necessary cooling air access. Unfortunately it HAS to be smaller than the full scale Bear.

Couldnít find one to buy so Iím making one.

Default Rare Bear Spinner

Chucked a block of foam in the lathe and removed everything that didnít look like a spinner!



Getting close

Perfect!
