Guillows Cessna build advice needed

Let us know the all up weight when the R/C conversion is complete. I flew the Guillows Super Cub free flight with the Pee Wee many years ago and it flew like a bird.

I don't know were but 20 % castor with 25% Nitro % will make the PeeWee easier to start and needle for you . The plane is looking Good so far keep it up you will get there . Here is some more info on the fuel > https://coxengines.ca/public/files/FG.pdf

That’s awesome thanks so much it’s a slow process with these kits just hope the pee wee delivers !!
Seems to be the easiest way reading that advice is to buy 25% nitro fuel and add the castor oil yourself using the chart interested to know what everyone does
More progress tonight ! Trying to save as much weight as possible

Don't pierce the stock tank!...you can fit a plate from the cox chopper, or else check to see if Ex model engines or Cox international still have the back plate for the Cox .020.
Sure you can pierce the original tank, but out there, if you get a plate, then you keep it in its original state!

Brilliant thank you ! Your model looks great will try and source the back plate I just love these tiny engines real screamers !!!
My last Cessna weighed in at 130 grams it needs 10 grams of nose weight hoping for less with this one I’ll use tissue and dope

Hi cp28,

Which kneck of the woods are you in ?

You know of dens model supplies for smaller Cox parts ?

Fuel, Weston's fuel contains no castor oil. Model technics fuel is still available but not sure if 25 percent is made anymore, legislation may have killed it off.

eBay/Amazon sells some stuff but I believe PAW engines can supply castor.

I have a peewee which I will probably never use....

The modern very light weight RC stuff opens up the viability of RC control for lots of small scale kits, even slight enlargement possibilities for the gaggle of 049's I have.
Silencers and RC carbs available for these.

I agree with Mauricio. Please don't damage the original tank. It's not something which is reproduced like the .049 tanks and is irreplaceable.
The 3D printed backplates which have been on offer seem to do the trick. If a chopper backplate like Mauricio's is available, even better.

Hi there
I’m in the uk if you have any direct links for this area that would be great otherwise I’ll just have to search for what you’ve said I’m sure we can still get model technics fuel here
I am aware of dens model supplies and have bought a few things from him fuel tank propeller fuel line and a glow clip as they seem to be hard to find also
Just had a search for a back plate none over here that I can see maybe If someone has a 3D one they could sell that would be ideal
Crazy gear has got so advanced and tiny now everything is possible
I’m using a spectrum A6420 receiver brick I’ve read that the mufflers if you can get one are not very effient I’d love to get hold of a throttle sleeve to tame the engine down but they also seem to be hard to get hold of I put another post on here asking if anyone has the details. On how to make one

Hi
No I’m not going to put a hole in the tank doesn’t seem right maybe I’ll find a spare tank hopefully

Hi Jim
Will do also have a super cub kit in the box after this project is completed
What was your AUW on that one ?
And what rc gear did you use

My Super Cub was free flight only. No R/C gear at the time (1971). I think it weighed 4oz all up but could be wrong about this. It's been gone a long time. I hope to build another one sometime out of nostalgia and possibly put R/C into it.

Awesome you should make another and convert it !

More progress !
The pee wee had an airframe or at least the bare bones of one
I’ve trimmed as much as I can from the fuselage formers to keep the weight down it’s always a challenge in these small models! I’m on the look out for a base plate if anyone has one spare or can 3d print one for me ?

My comment is no reflection on your building skills, but that Guillows balsa looks like rubbish! Appears to be soft and mushy from the pictures.
Well done on the build, but if it was me I'd be substituting some of the parts for more stable balsa.

Yes I agree to a point I always thought the laser cut kits were better quality oh well a little bit too late now !
