    Scale 1/3 Scale Extra 330L Build.

    Here's is the stab from the same build in a my drop cloth vacuum bag weighted down to keep it straight, without weight you end up with banana.

    Scale 1/3 Scale Extra 330L Build.

    Gorilla poly glue. Not sure what you have in mind, I would cut the blocks weighted down from top cutting both the top and bottom with the top up weighted straight on the bench. Here's an example of a rudder I cut 15 years ago. . Glue to skins with on with the core in the shucks weighted in...

    Scale RCM 1/3 Scale Champ Build

    The inlet diameter of the ram is 1.25", there's about 1 1/2" from inlet of the ram to the back wall. The box area is 6.9 sq. inches, area of ram pipe is 1.23", the ram and the carb are about the same area so there is about 4 1/2 times free area to that of the pipe. I was erring on the side of...

    Scale RCM 1/3 Scale Champ Build

    The throttle and choke servos are mounted in a removable tray on the back of the box. Four servo screws hold the tray in place so that the servo can be placed if the need arises. Unbolt the throttle and choke ball links, remove four screws and slide the tray out.

    Cut a hole in the firewall for the carburetor and velocity stack. The instruction manual warns against operating without the velocity stack as it will effect performance, my ram pipe information indicates the shape they selected will decrease performance by 1.2% to 5%. The shape is similar to...

    Scale 1/3 Scale Extra 330L Build.

    No, the foam you are using needs 1/16" balsa, 3/32" is going over open bays. Yes I have cut many foam core and foam rib wings over the past 35 years.

    Scale 1/3 Scale Extra 330L Build.

    1/16" sheeting is fine for foam if you are going over 1# foam, I would use 3/32" over foam ribs, my favorite wing construction. Here's a foam rib wing that I just finished before starting the Champ.

    Scale RCM 1/3 Scale Champ Build

    Kits are becoming harder and harder to find for sure. I ordered the cowl and wheel pants for the Aerobat this morning from Fiberglass Specialties. Sent a note off the WE Technical as well. You never know when the suppliers will go away. Spent the day playing cards, nothing accomplished today.

    Scale RCM 1/3 Scale Champ Build

    My trip to the Lebanon flee market yielded a Hostetler Cessna Aerobat 150 short kit and plans along with a 33% W. E. Technical Piper PA 22 Tripacer cowl and wheelpants. Both for $60.00. I'm pretty sure the cowl and wheel pants were made by Fiberglass Masters that is no more, both are blue...

    Scale RCM 1/3 Scale Champ Build

    There's not a lot of reviews out there and I have read those I could find. What made my decision easy was two or three years ago I seen a Roto 85 in a Hanger 9 Super Decathlon and performed great. I can't wait to see. Might have to set it up in a stand?

    First the bottom section is installed. Three 4-40 screws on each side. Then the nose bowl. A bunch of 2-56 button heads. Finally the top goes on, more 2-56 button heads and four 4-40's from the back side. Still need to make a hole for the carburetor and velocity stack to poke through. Then...

    Scale RCM 1/3 Scale Champ Build

    Got the engine mounted to the firewall. I really don't care for standoffs but with this engine you have no choice but to use them. I had originally planned to extend a box out then use shorter standoffs but decided that made no sense. Turned 4 custom length standoff's on the lathe.

    With the collection of weight it looks like you're stress testing to 10g's.
