Rc 1

Picked up a partially built airframe awhile back, can't remember where but I pulled it out today.
I ordered a set of plans from Bob Holman but in the mean time I'm fitting an engine, fuel tank and completing the fuse.
I've gone over the wing and made repairs so a good sanding and it will be ready to cover.
Chet built this model pretty sturdy, I guess to compensate for the heavy radio system and batteries.
Wing will never brake that's for sure. I'm going to fit a Saito 45 to the firewall but take out some of the downthrust which is huge. Right thrust is huge as well, maybe 6 degrees.

Would someone happen to know which engine Lanzo originally flew this model with?

Bill,

The 84" RC -1 was designed and flown in 1934. A Brown Jr. would be reasonable to assume being that early with gas models. It might have been the only engine in town then other than home builts. The next series of RC 1 were 108" as the smaller one was deemed by Chet to be to fast for his early RC gear.

Actually, the wryly named Racer at 144" predated the 108" Stick by one year.
I have the second Racer Chet built in my basement and I built my Stick using his plywood rib template.

Thanks Warren, this one is 84'' and I think it was a Brown also.
I'm going to try and lighten this model where I can, it's built like a brick.......house!

Won't be winning any beauty contests either but it might be a very close relative to the Red Ripper, also early.

Bill,

Found this on the SAM Talks newletter:
Quote:
In late 1934 the Cleveland Press printed a story and a picture of Chet and his RC-1. The newspapers lead in read: "A high wing cabin monoplane with a 7-foot wing spread, powered by a gasoline engine, capable of 50 mph, and equipped with radio controls so that it may be operated from the ground is an ambitious project developed by Chester Lanzo."


The RC-1 flying via radio control was similar to Wright Brothers first documented flight ...they both flew as the records show...but...nothing to really compare with the future designs.


In Chet's own words he flew the RC-1 successfully as both a Brown Jr. powered gas model and by removing the prop, a towline glider.


Regarding R/C, Chet states:


"When the equipment was mounted and the engine was running, the range was very short - less than 100 ft. The problem was in the model's ignition coil, which acting as a transmitter and swamping the signal from the ground based transmitter.
I would say the RC-1 should have not been considered a successful RC model in 1934 and 1935, but it was a tremendous success as a free flight model that could carry the additional weight of the receiver and batteries.
The receiver would only work when the engine was running and produce the vibration necessary to decohere the iron filings used in the control's coil mechanism".


Chet went on to state, " The RC-1 was retired after a bad crackup."


We can only assume the RC-1 did fly, or attempted to fly, with a semblance of RC control, as did the Wright Brothers first plane fly, with a semblance of control.

As Chester would say: "A lot of radio and very little control"

These early designs were first tested as freeflights and when flown R/C, would only be controllable in the glide. Frustration with radio interference from the engine led him to develop the Airborn(no E)

Chet was asked locally what prompted him to explore R/C. His response: "I got tired of climbing trees"

Nevertheless, somewhere in one of Zaic's books, there is a blueprint for his rudimentary Walston-type retrieval system.

Great, great info guy's thank-you!! All the more reason to get this thing airborn and I will.
Next spring I'll get the RC-1 and the Red Ripper out together and see which one thermals better. Then......the beauty contest, friends will have to vote and decide.

This model has a Clark Y airfoil, I didn't know that.
Should be covering the wing sometime this weekend I hope, yellow.
Have to wait for the plans to finish the rest.
Fuse wil be sky blue.
