Severe chassie flex on SRB, or construction error by me?

[akemag]

I´ve noticed on my (now disasembled) Scorcher, that there is alot of flex in the chassie. This has caused the front mounting hole on the body to wear, and it´s not perfectly round anymore. And i´ve been real gentle when driving it. Have i put it together the wrong way the first time i took it apart, or is it just the way the chassie is?

Thats just the way they are. A good cure is one of Twinsets awesome aluminum chassis or bolt some aluminum angle stock down the length or each side of the chassis to give it strength

Ok, kind of thought that i didnt put it together the wrong way. Maybe i´ll put some reinforcements down the chassie to strenghten things up a bit.

Do you have the original aluminium  piece that goes under the frp chassis??

Just a thought it might be missing[]

The SRB chassi is very flexible, it needs the alloy plate to help

stiffen it. So many radio boxes were destroyed at the front fixing by

the chassis flexing and hitting the box. I have two SRB fibreglass

chassis plates on my runner SRB to stiffen it up.

I got the aluminium piece under. But it should have stretched longer to stiffen the chassie up a bit.

Was the superchamp any stiffer?

Was the superchamp any stiffer?

SC gets a bit of stiffness from having the radio plate too.

This was the biggest problem of all SRB. The older ones crack the receiver case and the Super Champ sometimes the steering servo case. The second issue was destroying the bodies at the front mounting hole. Often the Scorcher or Ranger body broke completly at this place.

I solved almost 30 years ago this problem with a second chassis plate. The reinforcement plate only helped the radio box.

I really wouldnt want my scorcher to wear out the front bodymount hole. The smoother the road, the less flex it would get probably. Darn, theres no easy solution to this, if i´m keeping it standard. But it´s not going into "shelfmode", thats for sure.

The easy solution, as I use on my runner, is to fit a second chassis

plate under the original one. The car looks exactly the same as

standard, apart from the thickness of the chassis which looks twice as

thick but no one will notice.
