Bryan,

RE is the way I remember the Deception from my early years. In those days the 61 VF & RF were the engines to be had. I think the only issue with the RE setup on the standard design is that the canopy, unlike the larger ones on the XLT and Escape, is a little small for LS engines. On the other hand, a SS RE Rossi with a shorter pipe, much like in Jim's article build, might be just fine under the hood.

People who've built Deceptions with RE configurations have mentioned the issue with pipe heating due to the snug fit. Still, I'm going to build mine like that.

There were no long stroke engines when the Deception was released as a Bridi kit, IIRC. I bought my Bridi Deception in 1979 with the intention of running it with an OS .61VF rear exhaust engine, but I was disappointed in the power of both the VF and the FSR when compared to a Rossi or OPS .60 of that era. I ended up flying my Deception with the FSR (side exhaust) and Rhom Air gear. My model was grossly underpowered as far as I was concerned. Yes, I stretched the pipe out so that it was resonating best during the climb, but it wasn't enough of a boost. I thought mine was heavy until I read what some of them weighed from other members here on RCU.

I liked models that were more "in line" with the wing and horizontal stab, plus a bit of sub dorsal fin with movable rudder. Had I to do it again, I would have designed my own pattern ships and campaigned them.

Hi Ed,
I know you've mentioned your disappointment with OS side a rear exhaust engines of that era. They were not as potent as Rossi or YS. I flew several Deceptions with both the OS61VF and the YS FR. The YS definitely had a significant performance advantage. The Deception was very 'draggy' compared to other designs of the era, but a great flying airplane especially if built under 9 lbs.
You can still design, build and fly your own pattern ship - it can be very rewarding even if you don't get to compete with it. Personally, I can't see the BPA having a problem with anybody competing with their own design.

Deception...

Mr. Kimbro,

Do you remember the flight characteristics between your side exhaust powered Deception and the buried pipe RE version?

I am at a point in the construction of my model that I could change to the enclosed pipe version. I have a NIB Rossi .61 with mixture control carb/header/pipe from our mutual friend Rusty Fried (Rusty has a few more of these combos). I also have a replacement canopy from the Bridi Escape ($25 from Blue Bird in Nebraska) which would be perfect to replace your original canopy design.

Any plans on attending Rusty's contest in February?

In order to make these more accessible and available for all to enjoy, I did a very quick job on the scans Jim posted as PDF files. Here are the pictures of his White RE Rossi Deception. Date pictures taken?

Note how Jim concealed the header beneath the fuse top to enter the canopy from inside the fuse rather than exit over top. Were there any heat or space issues with this setup considering the area available for the header, tank and nose gear?

Looking forward to progress shots on yours Rusty!

David.

Hey Ed, Did that FSR you ran on that Deception have the 7M or 7D carb? If the 7D carb, did you try it with the carb insert removed and with a perry pump? Do you think it would have performed better if you ran it with the two mods I just metioned?

Here's why I'm asking. I acquired a 61vf with box and it had a carb manual for the 7D & 7DV. In that manual it references that you can remove the carb insert to increase the power but that it requires a pump. What do ya think? Here's the manual;

Doug,

any updates on this project?

I just posted a comment on the Prettner thread.

David.

Very interested in the Deception again. I'm curious if anything became of this project.

You can get cores and a fiberglass canopy from CPA Scott (sorry, I can't find his web address or email at the moment). You can get the Exception kit from Don Carlson at RCAIIR which is just a fiberglass fuselage version of the Deception. A personal favorite; I built 5 of them the last was a tail dragger for turnaround pattern which was very successful (Dave Wilson, a top competitor, also did very well with a Deception in the early years of turnaround).
Good Luck.
