You mean this ironically, donīt you?
To be serious, i am very unhappy with the bigmaxximum getting blown today.
I am dissapointed. You can say that i am a stupid idiot when i run a 18cell spec. engine with 30 cells, but my experience in the world of engines told me that thereīs no big problem with overpowering the device IF it is made robust enough!
Some examples: Hacker C50, operated far over specification. No problem.
Hacker C40 - the same.
Lehner 1940 - no problem.
Real world: The engine of my car delivers a power maximum 40% percent OVER the stock specification (bigger k24/26hybrid turbo, bigger+better intercooler, higher boost, only modified camshafts and better output valve shafts). No problem as far as you are requesting the power "wise".
BigMaxx spec: max 18cells, 30cells is something of 60% over specification for short bursts - not running 5 minutes a full throttle.
The BigMaxx looks good but doesnīt fit my definition of a robust engine.
Tell me: Why is it running so unbelievable hot? No brushless motor runs so hot! Thatīs the reason why there is a cooling fan fitted to the engine...
A lehner 1940 has simply NO NEED for a cooling fan.
Maybe the BigMaxx is overengineered but for my taste there is no need for 4pole brushless.
I can get several wanderer xls for one bigmaxx and the cost for the repair i think will be as high as a new wanderer.
And last but not least: The Plettenberg only runs good with schulze controllers this is not really a highlight.
So one may ask: Why did you buy this engine?
I bought it years ago in a combo with a savage brushless conversion set (schulze 18.97kwf), i would not buy it again.
I didnīt know that the plettenberg only runs adequate with the schulze controller.
The 18.97 had a half life of seconds, the bigMaxximum some months.
Too much money for me.
