ive had her in it a few times, ran into misc issues like trash motor connections, missing power recline controls, and such , but overall it performed well but is a STEEP learning curve as it doesnt just spin circles like a traditional chair so you have to think before you do
the BIG issue tho was the casters...i CLEARLY F-ed up the angle, and for reference of anyone working with casters..a 2inch rake on a 22inch wheel is NOT enough..it had BAD caster wobble at even a shufflingly slow walk, i spent a good bit of time pissed about screwing this up, tryed to correct it with tire pressures, weight, stiffness of bearings, eventually i spotted a marble counter top mover and the caster angle on it was what i considered stupid..caster centerline was on the other side of the tire?!?!?!, then started digging, theres no math about casters out on the net i could find aside from "if you have x problem change the angle in x direction....no actual numbers...noticed some commercial mowers with similarly angled front casters but were more tame..with the centerline being outside the wheel but not deep into the rubber
so i had to make some new ones and toss her in it for more testing, i went extreme and went 7 inch which ment i had to make an entirely new front end as a 7 inch rake would put the wheels into the frame...no good..i needed to make a front end i could "bolt on and space out", after testing with the 7's a few times and her now having logged probably 4 hours in the chair, shes driving it well and even took it down the street, all of the initial build teething is out of the way and we have tracked down a shop that can re-calibrate the old electronics..which was no easy task..should be getting it re-tuned next week
with the initial test of the 7's done and proven i could have left well enough alone and ran em..but i knew one of em had an "off" angle i wasnt pleased with..but they were "test mules" and ment to be scrapped , the 1 issue i did note was with the 7s it had considerably more resistance steering...so i knew id need to dial it back..but how do you figure out how far to dial it back...and at what speed, what about surface changes..sand, dirt gravel..AHHHHHhhhhhh....just make 1inch incremental adjustables for now tho im not sure how temporary they will be as i like the way they turned out and the adjustability may prove usefull, but more importantly untill its been on all surfaces i wont know whats best, and from a steering aspect i want the least angle possible, but from a speed aspect i need the most angle possible
once calibrated ill keep shortening the rake settings till the casters wobble then go back out 1 hole and then try all surfaces at max speed..at that point ill probably cut the excess off and re-do the front end to be something more perminant
