Ok then; the ongoing saga of the E Firestorm continues...
Having fitted the 23t Ansmann motor and swapped the rear wishbones over to increase the wheelbase, I finally got hold of the M2x8 cap screws needed to fit the clutch cover.
Took the truck out today, and played in the skate park, tarmac paths, farmyard and in a field
The 23t motor is a big improvement for me as the truck is a little slower and more controllable, and puts down the power in a really agressive manner. I'm pretty sure the batteries lasted longer too I think that for most people it would be a great investment to swap the tin 15t Firebolt for a decent racing rebuildable 27t. Although this may sound like a step back, it actually means alot more torque, and some of these Stock motors can get over 30krpm!
Had a few disasters though, but I'm getting used to them now:)
Firstly, one of the inboard ball joints of the rear upper link arm physically broke off at the stud. I can't see any good reason for this failure, but there were 2 washers under the ball, and the stud sheared at the plane between the bottom washer and the chassis.
I got me to the hobby shop and brought a pack of generic balljoints and tie rod ends. They are a smaller diameter than the HPI unit, but the stud is the same size. The rod end is about 5mm shorter than the HPI unit, so I moved the inboard balls to the outermost chassis hole, to ensure there was enough tie rod thread inside the rod end. I also installed the new ball joints without washers underneath. I did both sides as I wanted to retain the symetry.
Second problem happened after a few flips and cartwheels; the ESC pcb and heatsink seperated from the lower half of the case, which is glued to the chassis. It clipped back in without fuss, but did come apart a few more times.
As for the longer wheelbase, I'm not too sure about the difference, but it's less prone to wheelying, even with the increased torque of the 23t. I think the biggest improvement would be seen on a really powerful motor or brushless system.
