Mojo .40 engine?
 

What is the best saito for a mojo .40?

RE: Mojo .40 engine?
 

Saito 82 - GREAT MATCH

We have also used a 65 and a 72 in them - they also work pretty well

RE: Mojo .40 engine?
 

Gotta second the 82A, have one on mine! Hovers at about 1/4 throttle, pull-out is insane!

82 is the "best" saito if there is such a thing. Really though, the 72 is plenty of power for anything you want to do. I have one on my 4 3/4lb beater and it does great.

RE: Mojo .40 engine?
 

72 is pleanty, 82 is what I have. If it comes in at the lower 4 lb range a 72 may even be better (some think it runs a little smoother) below 4 lbs look at the 62.

Mojos typical wieght is about 4 1/2

I got a .72 on a .40 twist and it takes 3/4 throttle to hover. Dont know how much my twist weighs though. I rather have it and not need it than need it and not have it. I know the two are really close in weight and for another $25 bucks why not. Thanks for the responses. Also any pros cons to the arf vs. kit. I really didnt want to build a kit is the arf nice.
Thanks again.

RE: Mojo .40 engine?
 

The arf, if still available (Paul seems to sell out almost immediately after getting a batch in), is light and well built. Either the kit or the arf is great. Building a kit is almost too easy. If the arf is not currently in stock, don't hesitate to get the kit. You can have it together in less than a week of relaxed building time.

If you are not 100% set on getting a saito you may also want to consider a YS 63. I have a saito 82 as well and honestly there isn't much to separate them. The saito will spin about an extra inch of prop but the YS will give you more rpm. Power wise they are about equal. The YS transitions a little better, they both vibrate about the same amount. The only other difference is the YS has a pressurized fuel system. Don't be scared off by it, it is easy to set up and offers more reliable performance. The YS is a little more sensitive to the needle settings however.

RE: Mojo .40 engine?
 

For the Kit vs ARF question. do not be worried about building the kit - it is a really well put together kit and the building instructions (Which you can see on Pauls website) are some of the best I have seen.

The hardest and most time consuming part of building the kit is doing the covering. It is the easiest kit I have ever built and even I can put the entire airframe together in 2 days not including the covering (My building skills are pretty close to abysmal) - There are no compound curves to worry about and even my poor covering skills can get a reasonable job done of it.

I have a YS 63 in mine and love it. A 46 2 stroker should fly one good enough.

OS .55 AX

Unreal power, and half the price of a bigger four stroke.

RE: Mojo .40 engine?
 

Guys...The Mojo has been referred to me as an excellent 3D. I'm pretty sure I will order one this winter to have for the future, after I destroy the profile I already have learning to do this crazy stuff. The engine I have is a Irvine .53 ABC two stroke. Think this will be enough power?? Obviously trying to save $$$ using what I already got! Tom.

RE: Mojo .40 engine?
 

Yes
We had an OS 55AX on one for a while - it was more than adequate

RE: Mojo .40 engine?
 

The irvine will work just fine.

RE: Mojo .40 engine?
 

Irvine is a great Mojo 40 engine;) I like the Kit build better then the Arf, I get to tweak and cut wieght. But I have a 40 ARF that is top quality and flies fine, and so far has taken two hard dorks no problems[8D]


That 72 won't be nowhere near 3/4 throttle to hover a 4-4.5 lb MOJO 40, as I said many perfer it over a 82.
Twist may be heavy or you didn't have it proped well.

RE: Mojo .40 engine?
 

Ive been playing with props. I want to try a 14X4w. I currently use 15% cool power. Its good cause I can use the same fuel for all my engines. I really dont want to get on the 30% heli but i have one gallon and will try it if it wont swing that prop on 15%. I just wanted to avoid buy two types of fuels and switching them out of my field box. Plus how much money that stuff cost. I have two 1.80s and both have plenty of power on 15%.

RE: Mojo .40 engine?
 

Don't use the 30%, ounce you use it you won't want to go back to 15%! Saito's love 30%.
But all kidding aside the 72 on the mojo will work great.i had one on a mojo for a whole summer,good power but it wanted to torque roll in a hover real bad.i had a ST 51 with a tower hobbies muffler and the mojo had every bit of power the 72 had but a lot less roll in a hover.
real nice plane you won't regret it.
ENJOY!

RE: Mojo .40 engine?
 

That is what i heard. 30% fuel is like the crack of the rc world. Once you try it you cant stop using it.lol

RE: Mojo .40 engine?
 

The 82 will spin a 14x4w just fine on 15%, I use that combo on mine. I do have to second the above comment that the OS 55AX is also outstanding, especially with the Tower muffler that will give you a few hundred extra RPM's for $14.99. The big advantage of the 55 AX is that it just sips fuel compared to my 82, roughly twice the flying time on the same size tank of fuel. I'm finishing up my PRIMO this week and already have the 55 waiting on my bench to be installed!

RE: Mojo .40 engine?
 

I have the OMP Katana 40 size profile (very similar to Mojo) and an ASP XLS 52 with Tower muffler. It is veeeery powerful, swinging APC 12-4 at 14700 peak when fed 30%, but to reduce noise I now use a Hawk wooden (wide blades) 13-4 at 11700 peak and it is great power for my profile, and quite silent too.
This performed so well that a friend of mine flying the very same plane with a Saito 80 also bought an XLS 52 and now runs the same setup as I do


He commented that he now uses alot less fuel than when flying the Saito

RE: Mojo .40 engine?
 

Hey, i know this is off topic...but can y'all PM me if y'all still have the Mojo 40 plans? I'd like a copy of the plans to put together a Foam Mojo from scratch, and Paul already said he had no problems with it. Thanks!

RE: Mojo .40 engine?
 

The best saito to put on a mojo, is a ys 63!

RE: Mojo .40 engine?
 

From the guy that throws a ys in the trash because he wreaks into a cowpattie, Guess we have to be careful who we take advice from:eek:
