Mini Hog (oz6290)
About this Plan
Mini Hog. Baby Astro Hog. Radio control sport model. A reduced size version of the classic Astro Hog design, for .15 - .30 power and 4 channel RC.
Quote: "Re-create a spot of aeromodelling history with Harry Gilkes' 58% replica of the famous 1958 Astro Hog (oz4756) aerobatic design, for 12 to 15 size engines.
I suppose my reason for drafting and building a Mini Astro Hog is nostalgia - or old age, as our editor will no doubt say! The seeds of this model were planted many many moons ago when flying in the Gold Trophy (you know, the competition for the first real acrobatic yo-yos - models with no radio!) when I saw in the distance a 'remote control thing' performing real aerobatics, including outside loops! Later investigation showed this to be one of those new-fangled Astro Hogs from the US of A. So I suppose my interest in R/C was born - although I did not really take up radio flying until the arrival of proportional equipment. I could never master those reeds!
Many versions of the Astro Flog have been made, bitted, or redrawn in various sizes, some with the original aileron layout, some with strip ailerons, but with a tricycle undercarriage ...ugh, no way! The version presented here is really a 58% version (span-wise) look-alike of the original with minor changes to suit its smaller and less efficient size. The span was arrived a to enable the economic use of standard length 36 inch balsa. When, oh when, will our UK balsa people go to the standard one metre length of material? It will make things a lot better for both small designs (like wot RM publish, thank goodness) and real two metre gliders - nuff said.
OK, let's get down to our Mini-Hog which is designed around the 0.S. 15FP (or one of the reliable 12 BB motors) so do not be tempted to fit a bigger engine or the Mini Hog will go completely out of character and be ballistic. The prototype is fitted with a mixture of servos - semi mini Acorns ASIOs, Hitec 101s - but if you have, say, 101s and micros available this will make installation easier.
Final note on servos: If using root-driven ailerons as opposed to the prototype's two separate servos, use the more powerful semi-minis or minis on this channel. This comment also applies to the elevator. Again I must stress do not use above a .15 size motor.
So now to the building notes, starting with the tailplane Yes, I know-we usually leave this to last, but in this case the stabiliser is rather time consuming and can be built in stages while you are kitting the other bits..."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsHi Steve..just a quick one re.the 'Baby Hog'. This plan is by the late Harry Gilkes, and was a free pull out with the Nov. 1994 Radio Modeller magazine.he called it the 'mini Hog' This was his last published plan for this magazine,before he passed away. Many thanks for the site and your time and dedication...brilliant!

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
