RE: Piper Cub engine question.
 

I think you guys are right...I'm just going to do it right the first time.....ill return the.46 and just get a four stroke.

the magnums are decently priced although tower only has them with a blue head. Are the thunder four stokes any good?

RE: Piper Cub engine question.
 

I have the exact same plane....started off with the 81" wing and a sideways mounted OS.46AX with pitts muffler. It flew the plane just fine and ran like a champ.

But

3 years ago, I clipped the wing down to 67"for more sporty flying and 1 1/2 years ago put in a Saito 65 4 popper as that made this plane truly sound great. The Saito 65 does have good power but I might swap it out for a Saito 82 that is sitting on the shelf just to give it that extra ooommmppphhh.

RE: Piper Cub engine question.
 

Thunder Tiger 4 strokes are also great engines. On the Magnum, all you have to do is remove the blue valve cover and paint it with high heat engine spray paint available at any autoparts store for $5.....but the TT 4 stroke is just as reliable as the TT 2 stroke!

RE: Piper Cub engine question.
 

Boy you guys are a bad influence....just so my you know, when my wife sees the bill, I'm blaming it on you guys!<div>
</div><div>I purchased the thunder tiger f75-s 4 banger.</div><div>
</div><div>This should fit the mount that came with the plane even though the max the plane calls for is a .70 right?</div><div>
</div><div>
</div><div>That's a gorgeous paint job Sour.</div>

RE: Piper Cub engine question.
 

The argument with the wifey will be all worth it once you fire that 4 stroke for the first time!;)
And yes, it will fit.

RE: Piper Cub engine question.
 

Cool, thanks again for all the help you guys have provided.

RE: Piper Cub engine question.
 

I have the GP Fabric covered Cub and I am running the OS FS81 in it it is a four stroke...As some others have said Cubs really suit four stroke motors...There is nothing like the sound of a Cub purring by when it has a four stroke motor in it...I like the OS because it is a very clean running motor...It recycles its crank vent oil..Instead of blowing it out the bottom and all over the plane it recycles it and lubricates itself etc....It is especially nice with the fabric covering as it is a little harder to keep clean...The 81 is a bit more motor than you need but if you ever fly floats you will be happy to have the extra power...I have never been sorry to have this motor..I think it is a very good match.. I am glad to hear that you are going to get some help getting this plane in the air...It is a beautiful plane and it is worth taking your time to learn how to handle it properly...You can learn more about flying with a Cub than you can with most planes....They are very easy to fly but they can bite you on the butt if you aren't carefull ...

RE: Piper Cub engine question.
 

Oh you are going to be so happy you have a four stroke...I am even getting excited...I happen to be very lucky, my wife is very supportive of my hobby...She would sooner see me flying my planes than drinking in the bar or something like that... It sounds like you are just getting started..Before you know it you will have lots of motors...Swap meets are a great sourse of RC plane stuff .. Sometimes you can get unbelievable deals..As far as mounting inverted , I have better luck staying away from mounting inverted...I find when a motor is inverted if it has any extra fuel in it at all it runs to the bottom and pools there..Rite where the glow plug is..So of course it is very easy to flood...I just havent had much luck with invereted set ups although lots of others have ...I like to mount my motors up rite or laying on their side

RE: Piper Cub engine question.
 

Great suggstion, Bob. The OS/magnum 70 is great little motor, Or for the ultimate 4stroke experience and scale-like appearance an FA-90t!!

RE: Piper Cub engine question.
 

Boy, some of these guys sure like to jack up the price of someone else's project!! Sure the 4 stroke twin is really neat but look up the price! This is going to be this guy's second airplane not his ultimate dream plane of all time. I have the same GP Cub ARF with a sideways mounted OS 46 FX w/pitts muffler and it is NOT underpowered. His TT46 pro is equal to my OS 46 FX so it would be fine setup for his first scale plane and at an affordable price. As previously stated the pitts muffler will improve the exhaust note to an almost 4 stroke sound without breaking the bank. If funds are not an issue then of course a 4 stroke is nice but not mandatory. I also have a similar sized Thunder Tiger J-3 Cub (these are 1/5th scale cubs) also powered by an OS 46 FX W/a pitts muffler. Again, just fine in the power department for scale like flying, will do loops and rolls, and no problum taking off from a grass runway. They don't all have to have 4 strokes to be enjoyed. My biggest Cub is an early Hanger 9 fabric covered 1/4 scale J-3 with a Saito 120 4 stroke. For me, that's my ultimate Cub, but I also enjoy flying my other 2 stroke powered Cubs. Nothing wrong with them at a much lower investment cost. "89", if you have purchased the TT 75 4 stroke, it will fly your Cub well, but the 46 2 stroke also would have done the job, it's just a matter how much you want to spend on each new project as you add to your hanger. BTY the Great Planes J-3 is a sweet flyer, you will enjoy it no matter your engine choice.

RE: Piper Cub engine question.
 

Thanks for the comments guys....I'm a nit picker when it comes to projects or when I see something I like.  Eventually, someone at my field would have showed up at the field with a 4 stroke cub and I would say " dang, I should have gotten that I stead". Then I would have purchased a 4 stroke and been stuck with a nonreturnable 2 stroke.<div>
</div><div>I got a decent deal as tower had 20$ off coupon and free shipping, so it came out to 200$ even with glow plug and the nut.</div><div>
</div><div>The .46 cost 109$ so really after the return it'll be 90$ out of pocket which is t bad for a 4 stroke setup and a better sound!</div>

RE: Piper Cub engine question.
 

Down the road you might find you like this plane so much that you want to up grade the landing gear..You can get Robart Landing for it . I put Robart gear on mine and it was a huge improvement..It is expensive though,I think around $150.00...I can't rember exataly..I found the factory gear was a bit lite and I was forever bending mine...Its important with Cubs that the gear is straight because they like to ground loop if you arent careful..If the gear is straight and the wheels rolling free it helps ...I have been flying mine for 3 years and I really like it...I have 7 Cubs all together 2 1/5 scale 3 1/4 scale 2 1/3 scale They are not all flying though I have a 1/5 scale hanger 9 J3 Cub NIB And I and I am about 1/2 way through building BUSA 1/4 J3 Cub Plus I just got one of those new Hanger 9 PA18 1/4 scale Super Cubs for Christmas .. As you can see I am a bit Cub crazy ...The GP 1/5 Scale was my first and I think it is one of my favorites...Even though it is an ARF it dosent look like an ARF...It is also very sturdy...Make sure you use the struts and upgrade them...If you want I can take some pics of what I did to mine and you could do the same thing to yours...You need some 3/4" and 1/2" streamline tubeing and some 1/2" bar alum. and a band saw.... and a drill press....

RE: Piper Cub engine question.
 

You are going to love that Balsa Usa Cub. I have that plane myself in the Super Cub version, 110" wing span with a .91 Magnum FS and it flies very scale.http://www.rcuniverse.com/forum/js/f...eeth_smile.gif I'm a Cub fan myself, though my collection is not as thick as yours yet, I also have a 72" Arf J-3 with a .46 ax that is about to go on floats, a 96" Sig with an Asp .61, and several electrics including a few Hz Super cubs and Parkzone J-3's. I would like to add that Hangar 9 cub and the Goldberg Cub to my collection, probably won't be in next few months though unless I run across a real steal on one of them.

RE: Piper Cub engine question.
 

Thanks Biker, that would be awesome if you could snag any pics of whatever upgrades you have done!</p>

RE: Piper Cub engine question.
 

Cubs fly on the wing, you do not need more than that to power it. You will need to move your batteries forward and add some lead. Do not worry, that model will not know you added weight. My OS was sideways, and had a pitts style muffler. Remember always to stick a bit of a paper towel in each of the exhausts of the pitts muffler. Otherwise you will have oil dripping out of the muffler when you move or store the model:-) I gave up slime power many years ago, and only use gas and big electrics now.

Good luck with the Cub, it is a sweet model. You will learn soon enough to coordinate ailerons and rudder:-) (or you will chicken out and go the easy way, mixing aileron and rudder in your radio...)

RE: Piper Cub engine question.
 

Great! Bikerbc maybe you can answer this:

Your H9 PA18 brings a scale landing gear. How is the quality? Horizon sells the replacement LG for your PA-18 for like 1/2 of the price of the Robart LG. I have a 1/4 Clipped wing Sig, and a 1/4 Scale Cub that need a LG upgrade...

Gerry

RE: Piper Cub engine question.
 

Well I havent flowen the Hanger 9 Cub yet but I am not overly impressed with the gear...But for 1/2 the price it is a steal...It is hard to say how it will hold up untill I actually use it...I dont care for how the rubber bands go on....I like the Robart set up better but then I am farmilliar with that and in all fairness I need to give the Hanger 9 gear a chance...For a ARF gear it is far above the norm...I would not be afraid of giving it a try...The bottom of the Hanger 9 Cub is 6 5/16" wide which is about the same as the Sig Cub so if you want to put the gear on a Sig Cub it should fit but the BUSA Cub Fuse is about 7 1/8" wide so it won't fit the BUSA as well....Robart makes two gears....One for the BUSA Cub and one for the Sig Cub....

RE: Piper Cub engine question.
 

Hugger How do you like your ASP ? I have been thinking about getting one of the ASP 160 Twin Gemini Clones to put in my new Hanger 9 PA 18 .. I have a Zenoah G 26 mounted on there now but the that twin is still temping....I have a Gemini 160 twin that is going on my BUSA 1/4 Cub...I have not run that motor yet so am not sure how much trouble a twin is going to be...From Hobby King they are only around $370.00.....

RE: Piper Cub engine question.
 

So far I'm very happy with the Asp .61. I only have a gallon or so of fuel through so far, but it runs just like every other Magnum two stroke I have. As I understand it, it's made in the same factory and basically "is" a Magnum with a different name on it.

RE: Piper Cub engine question.
 

Yes I believe you are rite...I think there are a few other names too...I have heard nothing but good so far...The Magnum sells for a little more but you don't have to deal with Hobby King

RE: Piper Cub engine question.
 

You are correct. So far I have had nothing but good luck with Hobbyking. But I only buy certain things from them and I buy from them with the knowledge that if I have any problems, I most likely will just be out in the cold. When I am really concerned about service and quality, I buy from Horizon or Tower.

RE: Piper Cub engine question.
 

Thank you for the info. I will measure mine later, but I am sure you got the right size. Will look at the gear at the Wram Show next month:-)

This is your landing gear: http://www.horizonhobby.com/products...-cub-HAN454008

Quite frankly the only powerplant for an 80" cub (if not electric) would be a 60 size gas engine: http://www.horizonhobby.com/products...ngine-EVOE10GX

Slime power is history! For slime lovers! This one is only $199.00 and the gas is (comparatively) cheap!

Gerry

RE: Piper Cub engine question.
 

Yes that is it .. I can't believe the price...It is a super deal...It dosent come with the airfoil covers but I think I would forget them anyway...One of mine broke when I was putting it together...I was able to repair it but I think I would sooner have the little bags that you tie on...It would just be easier to access the bands when you need to do maint...The Airfoil covers is part of what I didnt like about the gear....They look nice but the little blocks inside are easy to break and big paws like mine have a hard time getting that little block back where it belongs....

RE: Piper Cub engine question.
 

I have been trying to post some pics of my struts but for some reason I am unable to get the pics to post...It says they are doing it but they dont show up ?? I will ask my wife to help when she gets off work...She is smarter than me.. I am a Biker not a Ballerina if you know what I mean..
