Battery now moved and replaced with a Hailong cased version and I moved the controller to an under seat bag which is bolted to the seat and also holds a few tools. Space was tight as I never envisaged using that space. With the benefit of hindsight a bit more space would have been useful. This has improved the pendulum effect enormously. It's gone from dangerous to a bit wobbly. I hope I can fine tune the rest out by improving my techinque.
Could the battery not go under the boom ?
I've noticed that hard pedalling wants to rock the trike which in turn wants to slalom it.
It is noticable trike riders tend to swing their body from side to side when pedaling hard , maybe that is the effect causing the unwanted slaloming ?
Again I suspect much is down to me needing to improve rather than a technical solution.
One other thing I've noticed is the tyre scrub. Without Ackerman this is both heard and felt and is the reason for choosiing the fairly skinny front Marathons which have as low a rolling resistance as there is whilst having good puncture protection. I suspect some extra air in them will help but I always knew this was a design issue with little chance of resolving.
Noticeable as a noise on the 1st Python trike as you were sat inside the rear wheels and it had a 30" track , not sure I could feel it ?
Lessened now the track is down to 24" , or maybe a combination of more length putting the rear wheels further back and some wishful thinking ?
I'm still having the tendency to over lean into a corner especially to tighten the line when in fact pulling on the bars is the better option.
I suspect that leaning is a to ' stop it tipping over ' reaction ?
Again more learning needed but I am tightening the turning circle with practise.
I expect a practice/confidence thing , the rider tilting/leaning looks great on paper however in reality it is most unnerving when it happens unexpectedly.
However when you get it right it is a joy
I also need a wider BB as the chain now clears the battery by 2mm on the big front ring. The smaller one is currently unusable until that change is made.
Battery under boom ? this would allow no return chain to be moved out of it's path easier than dealing with drive side ?
battery offset to non chain side ?
Enough of issues though as the smile is wide on watching other's faces as you slalom a bit just because you can. My current view is that this is capable of being in regular use rather than just a Sunday machine and I see no reason why anyone who wants to shouldn't build something similar. If anyone wants better pictures of any area or measurements I will happily oblige.
Don't put ideas into his head ....
You know who you are !
