Up scale FatBoy

[Bowhunter]

Has anyone up-scaled a FatBoy? If so Id love to see it if not, Carl T.(The upscale master) Thats something to think about LOL

I am sure people have done it. I have a video of one that looks lke it is flying on a L2 motor - but it's hard to tell. I looked for some links - no luck .

What size are you considering? I am thinking that 4", 5.5" and 6" would be really cool! You could make the math pretty easy on yourself if you use the 5.5" tube - that's a 2.11x upscale. Remember this when you build it: YOU CAN ALWAYS ADAPT DOWN, BUT NOT UP!

Basically, put a 54mm mount in the 5.5" version!

You want Fat Boy's?

See https://www3.telus.net/public/albertaw/ and check out the numerous and various Fat Boys.

Also, there is a KLOUDBusters who flies a Fat Boy on M motors. I'm thinking it is 8" in diameter. As I recall, it is not exactly to scale because he had to extend it just a little to get the motor INSIDE the rocket.

I have a stock-sized FatBoy that is fiberglassed and has flown on G motors.

Just in case you don't feel like scratchbuilding your Fat Boy upscale, try this:

Available with your choice of 54, 75, or even 98mm MMT!

Here's a page that includes a couple pictures of Andy Schecter's upscale called 'Yo BATF'. Just scroll down - you won't miss it.

I built a Boosteres FAT Boy with 3 - 24 mm motors in the Estes E9 class with a booster that also flies E9's. It is a "kit' extention/bash. Rail buttons. Going to larger 24mm reloads for more altitude and smoke. Check it out at my home page.

Well one of the guys in the club has built a couple of 3X upscale Fat Boys (7.5") and 2.5X Big Daddys. Hope to see one fly at our first launch this year. If not maybe at LDRS 23.

A buddy of mine and I are planning on drag racing 7.6" diameter Fatboys at LDRS. Maybe we can get more people interested in joining the race!

I am in the process of building mine now, here are a couple pics...

That's not Lloyd?

Nope, not Lloyd, by buddy Mike in South Carolina. Although I believe Lloyd has built one also.
