Neither of you have a chance with me in this race
I also have an advantage because I live in Canada. I always have snow I've been building air sleds for three years now.

When testing my ramp by throwing stuff at it, it also collapsed. I guess you're not alone in breaking them
I'm reinforcing mine with some 1/2" poplar dowels that were too warped to use for my spar on a Shinden.

I guess I said that wrong. I destroyed my airsleds, not the ramp. I made my ramp from plexiglass or just snow so they held up fine.When testing my ramp by throwing stuff at it, it also collapsed. I guess you're not alone in breaking them

So one of the motor wires snapped inside the motor right next to the windings (probably due to one time I plugged the battery in backwards very briefly, and I've tried but am not able to solder it. While looking for a replacement, I couldn't find the Power Pack H on the store anymore (neither could I find the Dart), which is too bad because I wanted to get another power pack H so I could have backups for every part, and have a slight discount on each part. I guess FT isn't developing power pack H anymore unfortunately, perhaps the kits for it just wouldn't sell well because it probably scared away some builders with the soldering and highish cost. While looking for the replacement, I also noticed the older and generic Emax motors are cheaper than the FT Gremlin motors.
I'm wondering if there is much of a difference between these two: https://store.flitetest.com/emax-11045250kv-brushless-motor-emx-ac-1925/p774983 https://store.flitetest.com/flite-test-gremlin-1104-5250kv-brushless-motor-flt-3027/p785006
I am also wondering if there is a difference between these two: https://store.flitetest.com/emax-rsii-1106-micro-brushless-motors-6000kv-emx-rsii-1106-6000/p801045 https://store.flitetest.com/flite-test-gremlin-1106-6000kv-brushless-motor-flt-3030/p845488
The only difference I can spot is price and cooling ducts (between 2 with identical specs), so is there any advantage to the ft motors? Also, is there a noticeable performance difference between the 1104 5250kv motors and the 1106 6000kv motors?
I was thinking of replacing the ESC's as well, and maybe the board because they are all really beat up and may have gotten damaged by the time I plugged the battery in backwards. I think that this is the same exact ESC:https://emax-usa.com/collections/electronics/products/d-shot-bullet-series-12a-esc-blheli-s But I can't find the board from power pack H anywhere, and was wondering if anyone has a link to it or knows of a replacement. Thanks
P.S. I'm thinking of making this a 4s trimotor by adding an extra pylon over the fuselage

trimotor?? I can't wait to see!
Sorry you're still gonna lose though.

Current progress. Needs a light sand and then color.Any drawings/pics of your totally unbeatable design
Still need to build the tailfins and elevator & rudder & power pods.
Here's a plan attached (not the cut sheets).
And I have a thread:

I think I'm going to start from sratch with my design to optimise it for higher speeds and the trimotor. This time it'll have a slighly pointier nose, No side skis (if initial tests work), a middle motor mount blended into the fuselage or I might pull a 727 and have the intake for the middle engine higher than the engine (which means I'll have to make decentlt precise tubing), a smaller V-stab, and ironed off leading and trailing edges for minimal drag. It will also be slightly asymetrical to counteract the middle motor which won't be as close to the centerline as the 2 outboard ones.

Cool I can't wait to see where you're going on this. But I'm sorry to shock you so bad that you need a redesign.
Actually I really don't know how mine will compare. I started this build before this competition came up! And mine is more specifically to try to handle the powdery stuff.

I kinda wanna enter but I live in LA. We haven't had snow in 21 years, not without a drive anyway. The beaches are too crowded for something like this too. What I do have are dry lake beds. The same dry lake beds that land speed racing was born on.
Mind if I use some wheels?
Should be fine as long as aerodynamic thrust is the only propelling factor, i.e. no power to the wheels. I'm thinking maybe have separate classes for landcraft should any unforeseen problems arise?

Or make a ground effect sled. That is more efficient than touching the ground so there shouldn’t be problems with friction. Then all you need is some powerful motors and a good airframe.

Check the rules on page 1- it has to be on the ground. Otherwise you bet I'd be building an ekranoplan. After I win I think I'm gonna reuse the electronics in a GEV though.

Curses! Well there are other ways to go fast
