Hey guys, I'm currently flying an aircore colt with an os 70 surpass. I'm building a hangar 9 cub 40 and will be putting my running gear out of the colt into the cub. Is there any tips or precautions for the first time I maiden the cub? I'm unfamiliar with there flight characteristics. I consider myself an intermediate flier at best. Thanks guys.

The Cub will float much more than the Air Core Colt, you will need much less throttle for it to fly as well. Cubs have a very short body that I understand does cause some difficult flight charateristics, I think they have a tendency to tip stall and can be difficult to handle on the ground. I have a GP .40 Cub but have not yet flown it, looking forward to doing so this season!

cubs! where do i start!

first off.. a cub is a love it or hate it airplane! and i love them!!!

the guys who dont like cubs usually arnt flying them right! to fly properly a cub must be flown coordinated, meaning FLOWN UTILZING THE RUDDER WITH THE AILRONS!!! you can do this with a mix or just add a little right rudder with the right ailron. as well as left with the left..

in pratice this is really easy to do and you will be rewarded with a graceful flying bird that looks AND flys properly...

on the ground.. if you are putting that .70 in the cub just put in in to the wind and give it full power and a touch of back elevatorit will be off the ground in 5 feet!! now if you want scale take off right rudder on the ground will be required..

cubs are a blast ! after your done with it on the ground add floats! its a very versitile airplane

Thanks guys for your input. I have one other question. My OS 70 Surpass is dying. When I flew it today it started surging and making some knocking noises. This engine is about 16 years old and it spent about 10 years in my parents barn when I took an absence from the hobby. Anyways after I landed I turned the engine over by hand. It felt very rough and didnt seem to have much compression. I think I'm gonna just buy a new Saito for it but I am unsure of what size to go with. I need good power to take off from a short rough runway. Thanks guys.

I wonder if Brad likes Cubs?


I fly my H9 cub with a saito 56. It flies scale, nice a slow. A 62 or 72 would be fine.

I'd like to add that I lead into my turns with rudder and feed in opposite ailron to keep the cub level.
The cub is a plane where you will learn to use the rudder other than on the ground.

a scale cub is what many concider under-powered..and it really is.. the first full scale cubs had only 60hp and were later fitted with engines that went up to 150hp for bush flying!

if you want short take offs add a big motor!! (call it a semi-scale bush plane and put some large 4inch cub tires on it!!!)

a new .70 is more than plenty for the cub but think about this..


while over powered this is what i would do..

add a saito .82 and buy a set of the floats for your plane as well.. the .82 will have the needed muscle forfloat flying can spin a big prop for added thrust for really short tak-offs cost is not that much diffrent

the .82 is also a great motor for larger planes as-well-as small aerobatic planes

with the added power of the big motor flying thecub and its quirkiness is deminished to a point..

but remember to THROTTLE BACK. it will fly around all day at 1/4 stick or less(without floats)

here are a few pics.. my 1/3 scale balsa usa j-3 with a 3w 85b2 cs twin! (non-scale knife edge flight with floats is possible)lol and the 1947 full scale j-3 n63061 (short take off , one float out, glassy water on rotation! flown by me)

Did you land 2 years ago at the Skymaster's float fly in the brighton area.

i have not landed this full scale plane at the seamasters float fly, however it is on a lake in brighton...and i have circled the lake during the float fly

the balsa usa 1/3cub has flown at seamasters in 96 and 97 winning scale the 2nd year out, with and a 2nd the first year
