The last few months I have been working with Mike Gaishin on some improvements and upgrades on the Contra V4. I have been very impressed working with Mike on his determination to keep the V4 Contra...

I can attest that the BJ Craft Agenda is another excellent choice. Before it I was also flying an Inspire and I wasn't sure anything would fly better than that. But the Agenda flies everything I have...

I am running the 650 in my V4 and I run the same props as you. I also run the same gear ratio in my V3's as you. I feel they are very similar in performance. Only thing is that the 650/V4 combo needs...

Brenner sent me a V4 and a Kontronik Pyro 650 motor. I installed it in my Episode which previously had a V3/Neu. It was pretty simple to retrofit since I used his mounting plate with the V3...

Got it. I thought it would get rid of any bending moment on the motor shaft. But having not fully thought it through you'd then have to support both ends of the motor and the drive.

How about the possibility of a u-joint between the motor and drive? Or would that be too heavy?

Couldn't agree more, Brenner. If this was only about flying to me I would have ditched it long ago. The Contra has reinvigorated my interest in pattern as it was now possible to do what I tried many...

Well, I have found one big disadvantage to the stab fences. One of my cats loves to chew on the tips of them. They have such a nice, crunchy feel when he bites in to them! I have to cover them with a...

Well, it doesn't take much to make the Episode a very good model both for the Contra and a single prop. The model already comes with one set of stab fences and all I did was add another. It is a very...

Well, you might have to make the same mods to an Axiome + with a Contra installed. What I did to the Episode was to change the incidence of the wing, add more downthrust and add an additional stab...

That's pretty much what I have with the Contra Episode. I am extremely pleased with how that is flying now. I've been doing a lot with the 2015 schedules and it has no problem with anything. The...

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

I am running two fences on each stab half. The outside one is the stock fence that comes with the kit. The inside one is one I made that is slightly larger then the stock fence. They are mounted...

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

Try stab fences. I bet they do the trick.

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

I've read some technical reports that stated that a different number of blades between the front and rear would be better. Interesting to see someone doing that.

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

I had added the SFG's to my Contra Episode long before I reduced the incidence, so the theory of only needing them because the tail is flying lower with reduced incidence isn't working here. Also,...

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

Bryan, I'm not gonna go there with you this time. But just so my old, feeble brain can keep things straight, can I propose a couple of definitions?

Band-Aid - strake, fence, strip, addition,...

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

Yes, I added a dorsal to the Onas. It did very little compared to the stab fences. Oh wait, maybe I should have kept that secret? I can't start letting everyone know what I do! Yea I can, it won't...

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

In actuality, I think the stab fences may be even better then just adding fin area. It depends on where you put the area. What I have been seeing with the Contra is that most models are not bad when...

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

I've been talking about the need for increased fin area with the Contra for a while. I never did like using drag devices to add stability and from the testing I've done they do not work as well as...

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

Jim, I think that Brenner is going to adjust the recommended use of grease based on the current versions sealing. I honestly think that you could go 150 flights, then I would disassemble, clean, lube...

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

I have 213 flights on the new pinion system in the Nuance and no signs of wear. Also, I see very little if any grease expelling on both of my units. I have gone 125 flights without adding grease and...

I just posted some info about my Contra equipped BJ Craft Episode in the Episode thread. It has so far shown itself to be a great model for the Contra!

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

You can balance the rear prop by disassembling the unit and using the backplate that the rear prop mount on. I've been able to use the High Point shaft through that mount.
