Piper Cub engine question.
I just got my GP Piper Cub 81" today and am starting to think about how I'm going to mount the engine.
I boughtthis engine for the plane:
http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXKF97
my question is, can I mount this inverted to where the muffler will run underneath the plane? Im worried that the muffler will be to big in the aspect that it
would look horrible as far as scale goes and also that it may be to close to the ground.
Is there a better looking aftermarket muffler that can be used?
this is my first build so I may be wrong in both cases.

RE: Piper Cub engine question.
You mean like this? http://www.tjdmodels.com/black-horse-piper-cub-120-artf-p-1564.html
If so, that's what I want to do....I just hate the idea of how much the muffler sticks out or if its even possible for me to do it.
Yes, the wing is 81" total.

RE: Piper Cub engine question.
I would have personally used a 4 stroke, but you chose a great running and reliable 2 stroke. I would mount it sideways with a pitts muffler......plus a pitts muffler would make it sound a bit more scale (at least for a 2 stroke). Good luck with it, it seems to be a nice Cub!

RE: Piper Cub engine question.
Right, and I don't mind it so much but I still don't like the muffler hanging out like that. Call it the future scale builder in me but that muffler would keep me up at night. Do you by chance have a link to "Pitts muffler" that works for a thunder tigre?
is there any reason I should be worried about the engine being mounted sideways such as life of the engine or dependability issues?

Check on GravesRc.com or Bisson, they should have them. Im also 99% sure that pitts mufflers that fit the OS FX and OS SF .46 should also fit the TT Pro .46
And NO you shouldn't be worried about engine issues mounted sideways. The most important thing on any engine weather is mounted straight or sideways is to run it dry after done flying and use afterun oil or air tool oil to keep it from rusting.

There are no problems with side mounted engines. It will not effect the life of the engine at all.
If this is your first build, I would be more concerned about your first flight. You don't say if you have flown RC before or not. If not you should get some local help if possible.

RE: Piper Cub engine question.
CCF, this is my second plane( first is an alpha .40). I have been getting flight time in and won't be flying this cub without instruction either as I've heard takeoffs are different and require good rudder control.
Just like my first plane, I'll allow a more experienced pilot take it for the maiden.
Thanks for the concern.

It's great to see people still doing it the right/smart way,
enjoy your Cub.

That's definitely a good idea to let an experienced pilot do the maiden. The TT .46 pro is a great engine, I have one myself, but you may be a little dissapointed if you're expecting the same kind of power you are getting with that Alpha .40. A wing span of 81" is quite a load for a .46 engine. The TT .46 will fly that plane with the right prop and a good pilot, but it may actually be a little under powered compared to a scale cub, and definitely won't perform as well as the Alpha.

Like I said, it will fly the plane, but don't expect any exciting climb performance. Personally, If I was set on a two stroke for that plane, I would have put in a .61 , to .72. But my first choice would be a .70 to .91 four stroke, probably an .82 Saito if I had my choice and the $ to do it. But, you already have the engine, so go ahead and see if it suits you after you let someone maiden it. You can always put that TT .46 in a .40 sized plane later.

RE: Piper Cub engine question.
Lol, now you guys got me thinkin....I don't think I'm ready to dump the money for a four stroke but I'm really considering the thunder tiger .61 and just returning the .46.
I only chose the .46 because that's what tower hobbies recommended which obviously was not a good choice.

Thanks guys, do you really think a .46 will really be that under powered? Think I should step it up a notch?

Cutting the cowl for a different muffler placement might not be desirable, but it's not that big a deal to re-position a throttle linkage or even the servo for that matter if you decide to change engines. But I have to agree with Warbird40 that a Magnum .70 fs would be a fine choice. I have a .91 Magnum fs in a 110" Cub and I am well pleased with it, but I think a .91 would be a little more than what's needed for that 81" GP cub. Just my opinion of course.

RE: Piper Cub engine question.
If you are going to return the .46, do yourself the favor and get a 4 stroke! By the time you pay for a 61 and get a pitts muffler for it, you would end up spending the same amount you would for a Magnum .70 and the .61 will never sound the same! Usually when companies recommend a range of engines, the lower number is the minimun amount of power required to fly that model while the highest number is usually perfect for sport flying. Always buy one in the middle to the upper range of the scale.
