Okay, first of all, i wanna thank all of you who have contributed to this community. I have been taking in so much data in the last week or so that i feel like my heads gonna explode.
I need guidance from people who have done or know about the project i intend to do.
Basically, i use my car 90% of the time to commute to work and back. I just recently bought a house thats closer to work and the commute is in a rural area mostly. no highways, 60km/h speed limits, very little traffic. So the plan was to park the car, remove the insurance for the warm summer months and use a home built e-trike to commute. The commute is 23km long but is unfortunately in a hilly area...think rolling hills with 100ft elevation changes. the actual elevation from start to finish doesnt change much but there are some pretty decent hills.
The powertrain is giving me fits. Choosing the right powertrain actually is whats causing a dilemma.
so to summarize: Homebuilt recumbent tadpole trike ala Atomic Zombie Warrior. Me, 215lbs, range, 30ish km (18.6 miles) in hilly terrain with cruising speed of 50km/h+ and not too much slowdown up the hills.
I basically have three options.
1. RC motor powered, using HobbyKings Turnigy 80-100-A 180Kv Brushless Outrunner. I work in a shop with access to aluminum plate, hardware, mill and lathe (we're not really supposed to touch the last two...stupid health and safety). So creating a custom step down transmission is not a very big concern. The concern here is the controller. i have no clue which controller to run, or any advanced electricals associated with the RC setup. Electronics are not really my forte, probably why i didnt go for Avionics but chose Aircraft Maintenance. Something tells me this would be the most "performance" path but also the one that would be the hardest to fine tune and keep running.
2. Scooter motor. http://tncscooters.com/product.php?sku=106165 36V 1000w, i'm pretty sure this will have no issues propelling me. since its being installed on a trike weight and size of motor and components isnt that critical. If i understand correctly, controllers for these motors arent as expensive or complicated as for the RC setup?
3. Plain jane hub motor driving the rear 26" wheel. But with so many options in price/voltage/design/amperage its very hard to know what the actual needs are. I really dont want to spend 500+ on a 5303 Crystalite but at the same time, how bad of a Russian roulette am i playing with those sub $300 ebay kits. And will these hub motors be able to keep up on the hilly terrain? with the RC and scooter motors i would run them through the rear cassette offering me different gearing.
anywho, the battery pack is still undecided between 36v or a 48v,i'm shooting for 20ah, and it will either be cobbled together from old laptop batteries or Ping or HobbyKing battery packs.
i appreciate all your input and before someone yells out the "search button is in the top right corner!" The database is HUGE with a lot of information that is dated and the links/pictures are dead. Its a LOT of wading through tons of posts...and i've been doing it for the last week...
