gp patriot 40 and enya 60 7033
 
i have a 40 size patriot with an enya 60 2 stroke 7033 on a pitts muffler.

what prop (brand and size) for max speed given my setup. I plan on running 30% nitro heli fuel full synth oil 20%

i dont recal what this motor will turn for rpms either, its an oldie but very strong and in excellent condition

thanks

you have an over weight plane with the 60 in it.

more engine weight
larger engine mount
larger fuel tank
then add a pitts muffler for the power of a OS 46 engine.

I would try a 11x7 for best over all.

battery 6v is in back with the servos. balanced at 3/4 aft on cg range. modest trimming of motor and mountaided in the fact that there is no lead in the tail. thanks for your input but she is well within weight range :)

if i dont likethe way it handles or performs, i heard this motor: Evolution .60NX might be a good choice.

Regardless of fuel type, glow plug, needle or screw tweaking, I have not been able to get the Evolution .60NX with recommended tuned muffler to reliably transition from a few moments at part throttle to full throttle or to idle without the employment of an in flight mixture control. Then it's a beast. It may be just my engine that has the wrong fuel metering taper in the carb, but I don't think so. IMHO, the performance muffler should come with a needle and glow plug. If your planning on only idle or WOT then it's a non issue.

No one seem to be complaining about the Jett 56....Be nice if they would advertise it...that is if they want to sell more of them.

If I remember right, the powerplant instructions on the plane discouraged the use of a 60 size engine. The 60 NX would be an exception because it is a small case 60 size engine.

Also the OS .55AX
