Yes there was a post but I cant find it and apparently theres a jumper on the gyro esc where you can replace it with a switch. As for the body, I trimmed a little half circle area so no rubbing so no big deal.

Also, I searched but didn't find anything, has anyone put a switch on the gyro wires so it doesn't spool up when you plug in the battery? I like to throw the battle in and put the body on, and clips and whatnot, then carry it all outside, but it sucks with that thing winding out all through the house, and that's not even with the feet screwed to the pegs. How does everyone else do it? Thanks for the help.
Welcome!

Regarding the steering shock rubbing the body, I used a Dremel rotating tool with a sanding roll to remove body material. It ended looking great. I can post a picture if you want. It seem this doesn't affect the steering as it hasn't been mentioned much nor have seen cutouts made in the pictures you see in this thread.

LOL, for the gyro sound; I know what you mean, LOL. You can install a switch but I believe most of us connect the battery at the time we run the bike. On the bench, you can disconnect one of the bullets connectors that carry power to the gyro ESC.

Razor makes bigger ones but the problem with them is the shipping. I'll have to find a local skateboard shop to see if they sell them.

Yea they are the little ones. They still work but you have to go slow. The big ones you can hit flat out and the bike jumps well. I found a vid of my bike using both ramps.

Do you have a pic of the upper shock mount that TJ came up with?
This is how i make my upper shock mounts, it is 7 x 7mm square alloy cut to size & round the corners so it fits up in there nice & mark the holes & drill them & screw it in with a screw washer & nut through the chassis & the other screw just screws into the chassis using counter sunk heads, you will loose 3 adjusting holes but with the big bore i don't think you will need them, i am still running my broken chassis i fixed with these & have had a couple of good endo's & nothing has broke yet i am going to hit some jumps soon to really put it to the test.

TJ,

I've ordered a 1mm carbon board to reinforce the area. I'll two plates similar to the flat area the shock holes are, and will glue one plate on each side. I believe this should reinforce the area.

What do you think?

Yes mate that might work, i always say there is only one way to find out if something will work & that is to try it, let us know how it goes.

David I was thinking the same but I was going to put a bolt through each end as well as the shock bolt so that would spread the load over three holes.

This is what I was picturing, just using Aluminum plate instead of Carbon Fibre.

Yes, slowly works but no joy running like that. I'm wondering why your bike pitches up. Mine pitches down on the small ramp even applying throttle much like you. Could it be the depth of the parabola or what it's behind the Tx ?

Could be the bike setup possibly? I've been jumping all my life and on flat landings try and land rear first. I only would just blip the throttle on that little jump I'm sure. Pretty boring though David. That was the only time I've used that small ramp. The big one is spot on.

Two batteries should hold me for now... I want to pick up all the alleven and venom alloy parts in one swoop... Also the front disc brake kit... Ktm body, front axle upgrade,what else guys??? what weight oils do I need for both front and back??? I noticed there is an alloy gear support for the vmx, does it even fit on the mm450??? Am I missing anything else??? Thanks all!!!
