Status: offline 		Help!!!!

I am building a prototype airplane and I am using 2 e-flite 160 motors at 3.6 hp 2 castle creation speed controls and 2 thunder power 37 volt batterys. I am looking to use 4 or 5 hp engines instead but I dont know who makes them. I found that ther is the A100 and A200 engines but those are to big. Also I am using a 18 inch prop and I need to keep that diameter so does someone make 4 or 5 bladed props that I can buy. Thankyou

Status: offline 		The motor you have E-flight 160 will just do 4HP. When going for big power always do to the maximum voltage the ESC allows. The Hacker A100 is a big jump, its 8-10HP.
Axi has a 5345 size that tops out a just over 6HP with 12 cells.

http://www.soloprops.com/ has 4-blade adjustable pitch hubs and props.


How much thrust do you need/want?
I have a KMS (china motor) 5331 250Kv. With a 12S1P 3200mAh at 45 amps (3HP) it spins a Master Airscrew 16x10 3-blade at its max, 10,000RPM. The static trust is just over 12 lbs.
