Default Landing on front end over jumps, any advice please?

Hi guys

I have a Kyosho Inferno with a 21 engine. It has a fair few alloy hopups all over the car but more on the font end. Over alot of jumps i am landing on the front end of the buggy.. I am new to this so i am hoping there is a skill to landing them properly. Over the same jumps my mate's Swift buggy lands fine but all its body is standard and already carbon fibre.

Is there anything i can do or adjust to get the front to come down and even out for the landings?

thankyou!

I will try that but i think its the weight biased in the buggy as my mate who is new to jumping as well was going fine most of the time over the jumps. I may have been applying the brakes without reliasing.

Need a new front shock due to the landings snapping the shock shaft and i'll get back out and do some testing.

whats shocks you guys recommend for a inferno?

try a little stiffer springs and heavier damping for the front shock... i should think that'll do the trick...

2 cents...

You could be onto something there....If it continuously noses dives then the pads are dragging on the disc or even just the front brake more than the rear. I use trinity spring things on my 8's and they fit between the pads to keep the pads apart to eliminate drag.

When you come to upgrade the car strt with the shock towers when you bend them (I am assuming it's the 7.5 sport, that's what it looks like) then the actual shocks to the 777 shocks.

Do check the brakes are not dragging, if it's not that it's the shocks. The car should not need huge adjustment in the air. Talk to the guys at your local track and ask about springs (A lighter spring in the back is you general start, that wil help the car "Pop" into the air") and oils.

For now, pick the car up and drop it from a few inches onto a surface and look at the distance of the chassis from the surface. If the back is a lot higher than the front, then take some preload out and even the ride height out from front to back and try that.

There is a lot of info on shocks and jumping on the web, Google is also your friend

I would say just replace the one shock or go out and treat yourself to Kyosho 777 shocks... but thats a money thing, keep spending and at some point you may as well have bought an upgrade in car... i'm still assuming it's the Kyosho 7.5


Google with rc buggy suspension tuning. If you learn how the suspension works then trouble shooting will get easier the more you learn

It is highly unlikely that the car is nose diving due to excess weight in the front. The most likely culprit is going to be setup of the car as other people have mentioned. The slightly drag brake in the front will cause the nose to come down. make sure there is no brake at all on the front when you let go of the throttle.

Have any other drivers driven your car to see if it does the same to them? Just trying to eliminate that it is something your doing. I doubt it, but it is a good idea to eliminate yourself as part of the problem.

Just a tip since you said that your friend was jumping it fine. You may be lifting off the throttle too early in the approach of the jump causing it to nose dive. Try lifting off while your in the middle of the jump face and adjust your timeing from there.
