ESP Modified & ESP Fully Ported 4-BOLT 27.2cc Engine
anyone running one of theese engines? im temptedt o buy one next week or keep to my plan and buy a futaba 4PK...... hmmmm

kidd

i want one stroked with a reed to boot!

Gas jocky

I read somewhere that the new Zen four bolts will drink more fuel cutting run times to 15 mins, not that they drink a lot anyways. Is this just a rumour or has anyone else heard it?

8000ft

still twice as long as electric............

not if you use 8900Mah batteries

but a 15 min run time on these? even with a 4 bolt? I think it may be a rumor...unless someone is just running WOT the whole time, and never letting off the gas.

part-time

i doubt a stock one will but a modified one i could see something like that. the esp 27.2 ts reed case motor i was running would kill a tank in about 20 minutes.
