    The true sine-wave (vectored) controller & electronics set

    As far as I know, a precise estimation would be very difficult to determine. Sinusoidal controllers have the best advantage at very low speeds, e.g. starting. At high speeds it would probably be less noticeable. I'd expect to get more torque and less waste heat off of starts with a sinusoidal...

    Hubmonster 94% efficient 7kw NO LONGER FOR SALE

    John, that's why you need to build a tilting velo! :-) Best of both worlds, even if your commute is in a straight line. That said I've seen hpv's handle surprisingly well at 40-60mph speeds, low CoG is great. It's hard to know just how much cornering you can handle without cushy suspension or...

    Hubmonster 94% efficient 7kw NO LONGER FOR SALE

    I think that if I do end up using a sinusoidal controller like I hope to, Minimonster will live up to it's name and more. A well built motor and a smart controller is a great recipe for efficiency-- and power! :twisted:

    Hubmonster 94% efficient 7kw NO LONGER FOR SALE

    I feel like a fool, but we are talking about the ebikes.ca calculator, right? There's no way to add a custom motor to it... is there? Because I spent some time doing hand calculations for the Minimonster and I still don't trust those values especially since they're not far from yours, gensem...

    The true sine-wave (vectored) controller & electronics set

    And to see the connectors: http://velomastera.ru/shop/admin/pictures/501036b-5.jpg I could be wrong but it appears that it is possible to purchase 2 controllers and use the display with 2 Max-E's-- I know it was said dual Mini-E's will be an option, but dual Max-E's would open up the door for...

    The true sine-wave (vectored) controller & electronics set

    That's great news, I just read through their forums a couple days ago as best as I could, didn't see anything. I hope somebody here who is getting one before me will post a hands-on review. It really is expensive, but if you compare to the cost of a controller, BMS, and CycleAnalyst... well...

    Hubmonster 94% efficient 7kw NO LONGER FOR SALE

    I hope I can live in a place like that. My dad has worked on all kinds of commercial HVAC systems for the last 30 years. He has a bunch of retired Automated Logic modules sitting in a shed at home... used one of them and set up an 'economizer' that automatically cycles with the cool night air...

    Hubmonster 94% efficient 7kw NO LONGER FOR SALE

    John, when I build a fairing, I'll definitely be in the market for those! I mean seriously, the dream EV of the world is one that runs on solar power alone. The crazy thing is, for many needs that is possible! Even if you only get 200 or 250 watts out of a full solar fairing, that may still...

    Hubmonster 94% efficient 7kw NO LONGER FOR SALE

    You're pretty much spot on, and reading my mind! Short term, I'm in this for practicality. I want a low-maintenance vehicle that performs well... I don't mind modding or improving, but no oil or tranny fluid changes. =) I want to build it, then just feed it some juice now and then. I do like...

    Hubmonster 94% efficient 7kw NO LONGER FOR SALE

    John, I'm so glad to see you're finally selling the Hubmonster. I'm honestly quite torn... I don't think I need this much power, and I'll probably still go with the MiniMonster because of weight, power, 3-phase simplicity (I've been eyeing the Maxcontroller) and the fact that as of yet, I still...

    The true sine-wave (vectored) controller & electronics set

    I'm planning on using Johns motor, which is fairly high kv in high speed. I'm probably going to use 28s a123. Maybe 30s. I would like higher voltage for other builds, though. -Droid

    The true sine-wave (vectored) controller & electronics set

    They seem to have the controller up on their store now, but it's just a pre-order: http://velomastera.ru/shop/show_cat.php?catid=5&grid=1 Looks like the final cost is about $800 USD (24,000 rubles). Steep, but it's a VFC... and with continuous regen and throttle kick-down and an integrated...

    The true sine-wave (vectored) controller & electronics set

    GITech, I know that feel! I've actually been checking this page almost weekly to see if there've been any updates. As soon as this controller comes out I'm ALL OVER it! Given the complex design considerations, I'm beginning to look at building the simpler Jetrike MkII with modifications...

    The true sine-wave (vectored) controller & electronics set

    I read on the translated page there will be an implemented feature letting you specify a desired range and have the controller automatically limit power/speed to get the maximum efficiency out of your motor... and frankly, that's just cool. I like the sounds of this controller more and more...

    The true sine-wave (vectored) controller & electronics set

    gensem, I think that your best bet would be to use the 2x Mini-E set that andreym referenced offering in the future... Unless I'm imagining that statement. But I believe he mentioned a dual-mini-E controller set run on a single display/throttle; you should be able to configure them to work...

    whats your favorite beer

    Monks Cafe Sour Flemish Red Ale is my all-time favorite by leaps and bounds. Moosbacher Hefeweizen. Spaten Oktoberfest. Brown Shugga. Pretty much anything from Midnight Sun is awesome, even their T.R.E.A.T. Imperial chocolate pumpkin porter which is not so much pumpkin as it is nutmeg, cloves...

    The true sine-wave (vectored) controller & electronics set

    So if I come back here in 1-3 years, do you still expect to be producing the Max-E? I'm also interested if anyone has specific efficiency comparisons between typical PWM vs. sine. I'm a major lurker but I've planned through over a lot of different designs, and modeled many in Solidworks...
