Optimal for parkjet?!

Message Topic Search Topic Options Post Reply Create New Topic Printable Version

I need an engine for parkjet. I need one that's a realy screamer.
So I looked and found two engines that seems to meet the criteria.
Is there anything that favours the 3500kv over the 3200kv? The later seems to be real highly regarded among parkjetflyers though.

	i can tell u for sure, none here that will scream. even the LSPJ, if u look at those video closely, it doesn't sceam at all. i have tried that 3200KV u mentioned, its ok but not freaking fast.... we ppl here are crazy for speed. the max that we go for is 3500KV with 5X3 nitro prop, 2200mah 3s1p 25C, best if 30C. speed wise, maybe we are so used to fast plane that now, we no longer know what is fast.... anyplane for us is roughly the same UNLESS its a pylon racer. we have build a depron version of pylon racer with the above setup, man,..... .thats what i call fast!!! but nonetheless useful because u can't fly it well, most of the time u are trying to prevent it from crashing. * mine u the above setup pulled lots of amp so it will damage ur lipo rather fast. maybe u can try 4-6S setup which we haven't touched before

	Ok, I ordered the 3200 engine and tested it in bench. It do draw a lot of amps , just as U said. But wat a sound, the sound of sou´mething rotating realy, realy fast so I guess it's enough for ´me anyway. I guess U guys have set a lot higher bar for the need fr speed speed and I will probably not go past that. Haven't flown with it yet but any day now I hope for stable and calm weather för maiden of an SU37 with 2 of theeses bad boys on.
