Status: offline 		 I just got my GP Piper Cub 81" today and am starting to think about how I'm going to mount the engine.

I bought this 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.

Have you thought about mounting it sideways ?



Is this Cubs wing span 81 inches?

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.

Best regards,
Ed

is there any reason I should be worried about the engine being mounted sideways such as life of the engine or dependability issues?

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.

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.

Status: offline 		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.

Status: offline 		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.

It would keep me up at night mounting any thing other than a four stroke in a cub, just my humble opinion. I would put a .70 size four stroke mounted side ways in it if it was in my hanger, btu I agree with mounting the two stroke sideways with a pitts muffler......if you have to.

Yes.


The 70 4 stroke suggestion is what I would do. JMO

Status: offline 		 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.

Status: offline 		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.

It's a choice, just on low end of the power suggestions.

The .46 will fly it scale like. If you have the budget, you should invest in a 4 stroke. Magnums are good 4 strokes and affordable. It would be extra work for you to put the 2 stroke and then change it after a few flights (different throttle wire location, motor mount, etc). I have 2 Magnum 4 stroke and they have been great (a .70 or .91 would be perfect)

Status: offline 		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.

Status: offline 		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.
