Mega Der Red Max build 2021 - Putting the MDRM together
Build Entry
I attached the fins to the body tube using Titebond II; then I applied fillets using Fix-it epoxy.
No need to worry about Titebond bubbles or wells when they are covered up and help Fix-it epoxy adhere better.
Paint is done!

BT60 Blue Bird Zero from new Mean Machine - Engine
Build Entry
I probably wont, but I'm really thinking of installing this in the BT-60 Upscale BBZ.
My guess would be three C6-5's or C6-7's as I'm not sure how to configure a three motor mount in Rocksim.

Mega Der Red Max build 2021 - MDRM Nose Cone Paint
Build Entry
To try and avoid paint winkles on such a big nose cone I sanded the nosecone with 220 grit sandpaper, sanded down the mold seam and wiped it down after sanding. That should clean out any mold release and prepare the nose cone for primer. I primed the nosecone and sanded it with 400 grit sandpaper ... [More]

Changed stripes to 2cm wide instead of 2.3cm.
Shortened barber pole to 9cm long.
Lowered the bottom most black stripe by 2cm thus providing more center white space.
I think these changes make the model look closer to ... [More]
