Motor Upgrade With No Changes

[texasrob]

I just bought a new Super Cub DSM and have flown it a few times (it has been windy in Houston, so I have only done a few short flights). And I am having a blast. I was looking around online and ordering a few parts here and there and I came across a post which I believe was on this forum (but I am not positive) that had a suggestion for a motor upgrade that was basically plug and play (no motor mount change and worked with existing ESC and battery). Several folks chimed in that they liked it as well. Added about 15 to 20% more power and did not require any other changes. I think they said it resulted in slightly shorter run times, but nothing major. I wish I would have bookmarked it and now I have been searching all over and can't find the thread anywhere.

So, has anyone swamped out their stock motor with a slightly better motor that did not require any other changes? I was hoping someone knows a good replacement motor off the top of their head and I could stop with my fruitless searches. Also, my son will be flying this plane as well (I have asked him to log several hours in the ipad simulator first) so this suggestion appealed to me. A little more power and nothing else to buy, but nothing to dramatic.

I came up with a couple of my own mods for this plane and did some nice aesthetic additions to the blue trim with black electrical tape. It came out surprisingly well, so I will post a few pictures.

Thanks!

Not likely. About the only way to increase power over the brushed motor is to go brushless.
Then the ESC no longer works.
Increasing the power (you can do that with the 10x8 'float' prop) works but risks burning out the ESC- the weakest link in the power pack.

Thanks for the tip. I may try the float prop. I tend to keep my flight times pretty low (and will at least for a while). If I fly for two or three minutes, I am pretty proud of myself and feel like landing and taking a short break

If I go this route and end up burning up my esc, well then I would need a new esc anyway and could step up to a brushless at that point.

Not so much how long, up to a reasonable point. You don't want to exceed full throttle for more than maybe 15-30 sec at any given time to let it cool between bursts. If you just putz around you should get 5-7" I suspect.

Trouble with the fried ESC is the possibility of losing all control > crash.

Question for folks that have fried the ESC WHILE FLYING (other variations not relevant to this issue) - do you lose the throttle only, or lose all control?
