Any .91 two stroke and any .91 or 1.20 four stroke will do. We are building a couple of Top Flite Bearcats of roughly the same size, and both will be powered by the supercharged YS 110FZ.

I have a Royal Bearcat that I have been fling for the last 4 years. I have a Magnum .91 four stroke in it because my son had given me one. It flys the plane fine and I found out that with a 14/6 APC prop I have much better performance than I do with a Master Airscrew. I won First place at the Mint Julip in fun Scale Advanced 3 years ago and took Third this year. It weighs 11 1/2 pounds and is covered with Ultra Cote. I have Century jet retacts with Robo struts and a Robart retractable tail wheel on it. If you like a Lot of vertical performance and put retracts in it you really need more power. It probably flys pretty scale like with the power I have.

If you want to turn a large 4 blade, you might consider the RCV 120SP. I am installing an RCV 90SP in my Top Flite Spitfire. It'll turn a 15.5 x 12.5 4 blade and would fit fully in cowl, only requiring an adequate air exhaust for cooling.

My Royal Bearcat with an OS 91 surpass turning an APC 15-6. flies great. A very fun warbird if there is such a thing. Slows down well with the flaps. The challenge is to not bend the gear on landing. Those long struts can bend easily on a grass field.

Here are some pitures of my Bearcat

I'm curious, what's the wingspan on the Royal Bearcat? Does it come with an aluminum cowl?

Hello Sammy,

long time ago I had also a Bearcat, but from Marutaka.
It's the same kit, Royal will complete it in USA with decals...

My Bearcat flies with an Enya 120 4-Stroke, I try first an Enya 91 4-Stroke - but it don't work good.

It's a big Cowl.

Richard,

The Royal Bear Cat cowl uses ply formers and strip planking. The kit comes with an aluminum cowl ring that forms the front, curved area. It might have a total thickness of 1/2"

Wing span is 60"

I checked the plans and the Royal Bearcat has a span of 62 and 3/16s of an inch. It's a little over 48 inches long. My span is 62 so I must of sanded a little too much off the tips. I think mine weighs so much (11 1/2 lbs) because of having 8 servos and full retracts. It just makes it fly better as far as being smooth. You have to land gently but it seems to do that fairly easy. I fly off of grass most of the time but a lot of the contests are on paved surfaces. The one thing that is not very scale is the length of the main struts. The real Bearcat had such a big prop the gear was real lnog and it had a trunion that foled back on itself to shorten the gear when it retracted. I cheated a little by making the wheel wells closer together in the center of the belly pan so I could make the struts longer and they are still too short. I used a fiber glass cowl and saved a lot of work building the cowl but it wouldn't be as easy to repair if you happen to nose it over on ashphalt.

Sorry guys i coulden't get back earlier, As i was thinking 90 2 stoke would be plenty for this model, i am looking to get myself ST-90 with pitts muffler for this model. Now as for Flaps i would love to heve them but since this is traded airframe, builder never incorporated flaps in his construction, i hope to have good smooth slow landing but we will have to see that when that time comes....

I was thinking of using 4 blade APC Prop, now any recommendations about the prop...

Thanks,
Sammy

hellcat 1

I have flaps on mine. If the plane is fairly lite it will slow down pretty good. Don't know how a landing will be without flaps as I have never landed without them. I have over 75 flights by now. I keep a log. A 90 2 stroke should be plenty of power. I don't think a 4 bladed prop will be of any benefit. I do know that mine would barely loop with a 14-6 master airscrew but does a good one with a APC of the same dia and pitch. A freind of mine just tried a three blade 13-8 on a Norcal T-34 and he got much better performance with a Master Airscrew 14-6 on 91 Saito 4 cycle. Any more than 2 blades on model this size just aren't too effective. The only thing thery're good for are looks.

I guess 2 blade prop is the way to even on this bird, anyhow i just come to know that i need canopy for this Bearcat as the one i was given is not for this model, if anyone have one spare from Royal kit please let me know, i will buy it...

Regards,
Sammy

Guys,


I am looking for the Canopy for this model, i know its hard to find one from the kit but never know if someone has one collecting dust or from crashed model, as long as canopy survived with out bents, scratches i will be ok wth it...Please let me know as i will be sarting to work on the fuselage...

Props4ever

Otherthing i was wondering if i could fit Thunder tiger's Bearcat ARF's Canopy on my Royal Bearcat model, seems to be that diementions of both models are almost same!, if this is possibility that what are my chances to get TT Bearcat canopy.......

Regards,
Sammy

Hi,

I am about to order TT Bearcat ARF's Canopy, can someone please let me know before i order it....


Regards.

My Feedback: (24)

That won't fit. Look up dionysusbacchus. He makes canopy for the Top Flite Bearcat. I believe he even makes canopy for the Royal Bearcat.

Props4ever

Hi Richard,

I have sent him couple of Pms but he hasen't yet responded back so far, i am waiting for his reply back...

Just curious to know why Thunder Tiger's Bearcat Canopy wont fit on Royal kit?, both are in relative same diementions.....

Are you talking about the canopy from TT Rare Bear?

Props4ever

Actually Yes, A canopy from TT Rear Bear ARF, i just read from pervious posts that TT's model is Bearcat by all means, they haven't clipped the wing and may have done some changes to cowl if that only.....

Richard L.

My Feedback: (24)

I don't know. The canopy from TT Rare Bear looks a little small and too streamlined.

Props4ever

Well if that the case, then its better aerodynamics wise!, bit off scale but still relatively the same type.....

If i coulden't find original Bearcat canopy then this will be my alternate route to get my job done.....

Otherthing is that i just got email from a fellow who said that Dion won't ship out parts to other countries then US only, now is this true?, it dosen't make sence to me, specially if he recieves payment from customers for parts before sending out the parts.....

Hi Richard,

I went to LHS last night to compair TT's rear bear and my Royal Bearcat, both model are very much similar in size, they did not clipped the wings as both models have almost same wingspan +- inch or so, yes Canopy on RB is more stream lined but base frame is same.
They also have scale tail wheel assembly that i also ordered. Cowl is slightly different at the lower part compaired to BC, its more od sharp "U" shaped but is not "V" shaped....Overall its almost same plane with minor differences only...

Still looking for either Topflite Canopy or Royal Canopy...

Sammy
