So 9x9 wont be better than 10x7? Also, what was the stock speed? I think I read 60mph?

Hi guys. I haven't posted over here in quite a while but just noticed about 75% of the Super Cub thread part 3 members are here too..lol Anyway I'm wanting to gain a little speed but not wanting to replace the motor / esc yet and I see a 10x7 is suggested but is it enough to notice?

The 10x7E was plenty for me.. I dunno how fast it was.. I wasn't going for speed.. The best thing to do would be To buy both props and try them.. I usually go through 3 or 4 props on a plane until I find the one *I* like..

I second this.

With a Power 10 and 40A Pro ESC, I've tried the stock prop, 9x9, 10x10, 10x6, 10x8, 11x7, 12x6...in my experience the 11x7 gives the best combination of speed and vertical (and fun). With this blunt-nosed plane, I found that the "speed" pitches were faster than stock but not much different from each other, just pulled more amps, hotter batteries and less flight time.

The hands-down biggest performance improver in speed and vertical was removing the landing gear (imagine that!) I wish I'd done this sooner. Whole new bird.

Again, this is my experience...your mileage may vary.

That's precisely why I chose an eFlite Power 10. From other posts it sounds like there are probably better motors in this class, but this motor is an exact remove-and-replace with the stock motor/mount. The motor length is just right, so there are no concerns with cowling/prop fit. I didn't want to have to do any mount modding, adding spacers, etc...just plunk down more $$$ for more power and go fly.

I like to mod, but not remanufacture.

Good news!!!! My T-28 will be back in the air tomorrow morning with a new Scorpion motor installed under the hood and a 45 amp ESC backing it up!!!
Man I can't wait, I think it should be alot faster than the stock motor was...

Nice
just out of curiosity does your motor calculator tell your the same thingÉ
have you found 11x7 spins just too fast that you get poor air mix , low thrust.
mine is heavy so i need some tourque 12x6
11X7 or 11x8.5 just does not give me the thrust but less amps maybe 20% less

you like to experiment right, try the slow fly 11X7 (very different prop.)with power 10

that combo is super sized

don`t mention landing gear being better than gear on, it will create a big arguement lol

let us know

T-28's on the scrap pile.. ( Just Kidding )

I really like the Corsair.. But if you are recommending a trainer - the T-28 still rules..

This is just me, but I'd be careful running an SF prop on the Power 10.. At WOT the Power 10 is gonna be close to 450w, which IMO is a bit much for the SF prop.. Prop blade to the eye would ruin someones day..

I went to use my second 3 bladed prop from Parkzone this morning. Let's just say I won't be buying those props again. They look good but that is about it. They are extremely weak. I was about 200 feet up, doing snap rolls and tight loops when one of the blades broke off,hit my canopy and knocked it off. I'm gonna go back to the ol' faithful 2 bladed prop for now. I also got to get a new pilot as for the old one had to "punch out"! Still managed to "dead stick her in without a scatch except the one the prop left.

That is very true! But give it a try and don't go crazy with the power, you won't need to, that is my point try it out just for fun. It will fly completely different than the ones you tried so far. Be carefull Tram is right about it not suited for power 10. but power 10 is not suited for the Trojan anyways.
Don't you just hate the guys in suits who make up the recommended factory configurations. just jokeing
apc e are the recommended props..
the size you use depends on what you like.

APC SF props are good for 65000/prop diameter..

A 9" prop is good for 5,xxxRPM...

Use something that has a better chance of staying together at the hub..

hey Trojan pilots, I just finished mine up and was wondering, what are you guys using as the CG? Common sense tells me to use the spar or just in front of it as a start, but wanted to check with you guys first. Lemme know so that I can go
Maiden her tonight!
TIA

I used the recommended CG on the manual.. This can be found at Horizon's site if you have lost your manual..

thanks Jeff, I reviewed the manual twice and missed it somehow! And didn't even think about going to Horizons site, thinking all I would find would be a PDF of what I already had! Okay, back to the manual and apparently remedial reading class! LOL!
