Hi guys,

I just got one. The gear is a bit weak for a .91. A mod would be in order. That may be the case for any engine. The gear metal is very thin and the mounting is the sandwich type. To do the mod I’d think you would have to rip it out all the wood to get any thing bigger (gear) in. I’m going to stick an O.S. .61 in and see what happens. Spent about 8 hrs on it and I am almost done. The book only has something like 20 steps

This thing is not even as large as their .40 size P-51. Jett 90 is way to big (size). Engine cowl may get all hacked up. How about that 60lx

It should be fine with the 46ax mounted sideways. A pitts muffler would be in order though to keep the lines clean. I'm going to build one with the 55ax.

That OS 61 looks about right in there. Put a APC 10 X 10 on it and you'll find out real quick if it will hold up. I hope it does, it's a sweeeeet looking plane.

PS work up the speed. Make near by passes and listen for flutter. If you hear it pull up and cut power!

Well…..
I snuck out this morning and flew it…. NICE!!! Still my only complaint is the gear. I had to take off the spring because it was getting caught up on the grass (grass needs to be cut). I figured one flight won’t hurt. WRONG!! Take of run was a bit squarely but I am going to blame it on the long grass and a motor that provides more torque that the airframe was designed for. In the air the plane was a dream. Not real fast but I don’t think the engine is propped for speed. Just two clicks of right trim on the aileron and one click on the rudder. Flew for about 7 min. and it flew very nice. The recommended throws are not super responsive but are a good starting point. No flutter, no parts falling off. I’m happy. This is not my first speed plane but it is the first time I have tried to get speed out of a .61. For the second flight I maxed out the rudder and put in a touch of expo. With that setting I got much better ground handling. Landings were much slower than I thought, given that the plane is heavy with the .61. This is where the disappointment came in. Two landings soft and level, and two times the gear flattened to the point that the belly touched the ground and stayed there. On the other side of the coin, I did not hurt a thing. Both times I simply just bent the gear back to shape. Nothing broken the gear just pancaked out so bad that the fuse is what stopped it. If you fly off cement good luck and be careful. I believe you will have a problem no matter what engine you put on it. A 2 stroke .61 cannot weigh that much more than a 4cycle .52. I am going to reinstall springs in an X pattern and try again tomorrow I’ll report back.

P.S. I’m going to get more speed out of it for sure.

I looked at them both at the LHS and picked the NEM. Looks like it is the same model with a different cowl and the NEM. has fiberglass wingtips added to what I think is the same wing. I think the difference in speed would be negligible, especially if you plan on overpowering it. I don’t plan to do any sort of competition with it so I got the one I thought looked better. Both of them look good. It was a hard choice. Good luck.

One other thing you might want to consider….. I think the Barbera Jean would be much easer to see. Don’t hold me to this but…… if my memory is correct the Barbera Jean has a white bottom on the wing, and with all that red on top it would be much easer to see turning at 100+ mph.[>:]

I plan on using “not being able to see the Nemesis because of all that white” as my excuse when I finally make it a pile of toothpicks![:'(]

Yep...blue and white aren't exactly the easiest to see...and the silver/gray trim doesn't help.

It is a nice looking plane though...they did a decent job on both of them.

A Webra Speed .61 would be a nice choice...the Tower .75 too.

The biggest difference is, one is a low wing and the other is a mid wing.

Six more flights today the x pattern on the springs did the trick the springs are C-33 from Ace Hardware. Think I will shim in some right trust. This thing goes hard left on takeoff. The plane is not slow but blazing fast are not words I would use either. That said, others at the field seem to think it is fast. Other speed planes I have are the Cermark F-16 and the Sig Wonder with a .32 in it and I think those two planes would leave this thing in the dust. Don’t get me wrong, I like this plane. I just would not get it if you are looking to set a club speed record. I’ll keep trying different props ‘till I fold the wing up!! I’ll keep you guys posted.

Cheers

i had the barbara jean with a jett .50. To do it right you need the in cowl muffler from jett. I didnt like the way the plan tracked in air, it never really locked in for me. Take offs where very hairy as well. The third take off got me so i stomped mine in the ground to finish the job. I put the jett in the Phonix F 20 and love it.

I can see what you are saying Paolino. For any of you others that want to get this plane: I increased the rudder throw to max and put in some expo. When I takeoff I slowly advance the throttle and fed in right rudder. That way, I am able to keep the left turning tendencies under control. (If I just shove the throttle forward, that is when it goes hard left.) I don’t remember off the top of my head how much rudder I leave the ground with. I’ll keep it in mind and report back if anyone cares.


Paolino,
Was the gear as soft on the barbara jean?
