Haven't built an IC Engined profile model in a long time. Skybees were about 50 years ago  ;)

I found this on Outer Zone, and decided to try to adapt it in Corro

Thanks Shirsa. I guess the logical first step is to get an engine and it's associated paraphernalia and get familiar with it. Then select a model suited to it

Thanks Sir. Which engine do you think best for beginners?


Title: Re: Dart Cart III
Post by: sanjayrai55 on January 25, 2022, 11:18:37 AM
Nothing really like a beginner in this. See what's available, and in your budget. Also, it would depend on the kind of field you have

In Glow OS are the most popular, in Gasoline DLE

The "40 size" Glow engine probably has the widest range of available models/ model plans

@sanjayrai55,

Lovely as usual, sir!

Read the magazine article. Should be an excellent flyer.
Will the sharp leading edge make a difference?

Regards

Thanks Iyer sir

All my corro models do have a sharp LE. They seem to fly OK.

Sirji,


If you can create a round LE with coro, after bending the wings. Take a sheet of coro having flutes spanwise. keep 3" top & bottom.
Use this sheet to wrap around the LE, you will get a round LE.

I have tried this technique on my big models. Works good

There are many ways, and I have successfully tried some. Suffice to say I did not find it essential to performance

Successful maiden today

The engine was new, so ran in ~ 2 tanks, and flew at a richer setting

Will have to put more sponge foam between tank and fuselage, there is excessive foaming in the fuel

Really smooth.
No adverse effect of sharp LE at all!
