I would like to try a more powerful engine than 2826 2200kv w/40 esp what do I try which plane likes more power ?

Hi Jim -

There is a thread here where I and others have shared bench and field test data on a wide range of motors and prop combos.

I'm not sure how to answer your question about which plane likes more power, it can depend on how much drag there is (F-18 having more drag than a Mig-29 for example), how heavy the plane is and what sort of performance you seek.

Even just keeping the same motor and ESC, you can get an increase in performance just by changing props. I and many others have used the Master Airscrew 6x4x3 prop with the motor you describe and it provides considerably more power and speed than a 6x4 APC style prop with only a few grams of weight gain.

There are a couple of motor choices that will still work well with your 40A ESC depending on the prop you use without adding more weight to your plane.

If you really want a lot of power and speed, you can move up to something like the NTM 3000 motor which needs a bigger ESC (60A) and bigger battery. Your plane may also need a bit of reinforcement to handle the punishment. On average, you can expect about a 3 oz weight gain to go to the NTM 3000 setup over what you are using now.

If you can be a bit more specific on what sort of performance you seek, I can give you some ideas on different motors and props I have tested or that others have used with success.

Although quite detailed, I have attached the motor testing spreadsheet you will find scattered around the parkjet motor bench testing thread above.

Good luck

Cheers,

Scott

I like the Zoom 450 from heads up supply. I have more powerful motors but the Zoom is a good step up in power without having to go bigger on the ESC.

I posted some air speed figures for 4 of the RCP jets. The F-18 is clearly he fastest , but also a bit more difficult to fly. I like the F-15 a all around performance it flys great at full throttle smooth stable and has a very slow landing speed.

I have a 2836/3500 kv EDF engine in a mig 29 and it's very powerful. I bega with n a 5x3 prop and full throttle is OK and fast but slow to accelerate. I also tried a 6x4 prop and full throttle has so much speed and vibration the jet has a control issuw, probable due to vibration and air speed across the control surfaces. I used a 60amp ESC 6X4 prop and 2200/35C battery with low heat on the ESC and motor no problems at full throttle. Crazy loud engine sound but for all the work and expense the 2826 turnigy 2200 kv with a 40 amp ESC and a good 2200/35C battery is plenty fast in the F-18 hornet. I recently posted some air speed numbers and the F-18 is clearly the fastest RCP jet. My speeds were 67 mph with the 2826 turnigy 6x4 prop and 40 amp esc on the stock F-18 with 30" wing. I think it will exceed 70 mph with a few mods. If you haven't flown a 70 mph jet it's REALLY FAST !

With the older NTM 2836 3500 kv motors I found better speed using the TGS 6X3 prop then the APC 6X4 ones, 60a minimum esc but usually 80A and my Zippy batteries are all 65C.

Thanks for the prop advice I will try a 6X3 instead of the 6X4. The 5X3 was slow on takeoff, made lots of noise but not the best power or acceleration.

I am jealous...with my 2826, 6x4, and 40 esc with Mig 29....I am only able to get about 62 mph. It is probably my poor building techniques! chas

On 6S the 5X3 will go. Just for shits and giggles I tried my NTM 2836 2200kv on 6S with a APC 5X3 , wholy crap, should have a scatter shield and definitely hearing protection. I don't remember how many watts or amps but I think it was around 90oz of thrust or better.

But the TGS 6X3 prop from HK, real good performance every which way. I think with the slightly less pitch it allows the motor to reach peak rpm with ease.I do believe the prop is slightly longer then the APC prop.
