About this Plan

Beechcraft Bonanza. Radio control scale model. Wingspan 81 in, wing area 1040 sq in, for .60 to 90 engines. Scale is 1/5.

Discontinued kit from Top Flite.

Quote: "Introduction: From this kit you can build either the V35B V-tail (1970, 1971) or the F33A straight tail (1970, 1971). If you like the looks of the V-tail best, don’t be intimidated. Actually, the V-tail is a little easier to build than the straight tail because it has fewer parts! See page 7 for more comments on the differences between the V-tail and the straight tail.

Since this is a scale model with lots of detail, you’ll find it takes a little longer to complete than the sport models you’ve built before. But since this is a Top Flite Gold Edition kit, it isn’t more difficult to build than those sport models. The Top Flite Bonanza uses the same materials and standard construction techniques you’ve already become accustomed to. You won’t have to learn anything new to end up with a first class scale model! Not only that, nearly all of the trim schemes you’ll find on full size Bonanzas are quite simple and should be easy to duplicate with Top Flite MonoKote film!

The Top Flite Beechcraft Bonanza is an excellent Sportsman or Expert Scale subject. Its large size and accurate scale outline afford you the opportunity to go all out with as many extra details as you like. And with the abundance of Bonanzas at airports around the country, finding a full scale plane to model shouldn’t be a problem. The option of building either a V-tail or conventional tail opens up the possibilities even more!

Anyone who has mastered a low wing sport model should be able to fly the Bonanza without difficulty. It handles very much like a full size Bonanza - smooth and predictable.

Because of its 81 in wingspan, the Top Flite Beechcraft Bonanza is eligible for IMAA events. In order to be IMAA legal some of the control components and hardware may need to be replaced to conform to Giant Scale rules even though this model does not require heavy duty hookups.

Several scale accessories specially designed for the Top Flite Bonanza are available separately including a full cabin interior, in-cowl exhaust system, and a complete lighting kit. See the Scale Accessories section on page 5 for more information.


TAIL CONFIGURATION: You may build your Bonanza as a straight tail or a V-tail. Complete instructions are provided for both. The main differences in construction are building the tail surfaces themselves, the way they mount to the fuse, and the turtle deck sheeting. If you wish to utilize the elevators as ruddewators (elevators and rudder) on the V-tail, you will need a computer radio with V-tail mixing or a servo mixer such as the Ace MixMaster (ACEM2510). However, the Bonanza will fly just fine with elevators only and no rudder input. Do not be intimidated by the V-Tail configuration. It flies beautifully and is as easy to handle as the straight tail.

ENGINE SELECTION: Recommended engine size: .60 to .91 cu. in. 2-stroke -or- .90 to ,120 cu. in. 4-stroke.

The Bonanza will fly well with any of the recommended engines. The 4-stroke engines and most .75 2-stroke engines will turn a larger prop at lower RPM’s. This is often desirable for scale realism. Many .60 2-stroke engines produce about as much horsepower as the popular .75 or .90 2-stroke engines and will fly the Bonanza well. If you use a .60 2-stroke, a ball bearing, Schnuerle-ported engine is highly recommended. Our prototype Bonanza weighed 13 pounds with all of the options, including flaps, scale cockpit interior and operational lighting, and was flown with a SuperTigre G-75. It turned a Top Flite Power Point 12x8 prop at 9,600 RPM. This engine provided excellent performance and more than enough power, even in gusty winds. Although larger engines can be used to power this model, the extra horsepower is not needed.

The included adjustable engine mount will hold a range of engines from .60 2-stroke through 1.20 4-stroke.

EXHAUST SYSTEM: A Top Flite header and muffler are available that will fit inside your cowl. They are designed for 2-stroke engines mounted horizontally, as used on the model and shown in the instructions. For part numbers see the accessory list on page 6.

RETRACTABLE LANDING GEAR: You may build the Bonanza either with fixed or retractable landing gear. Of course, fixed gear will be much easier to install than retracts; but we provide detailed instructions on retract installation so you should have no trouble. We chose the Robart #BZA80 retracts because they are specially designed for this model. This landing gear is a special adaptation of the Robart #640 mains and the #631 nose gear. Other systems may work as well but it is up to you to make modifications to fit them into the model.

FLAPS: This model was designed to incorporate scale flaps; however,flaps are optional are not necessary for an excellent flying experience. Without flaps, the takeoff roll is longer and the landing speed is faster.

The flaps are not difficult to build, but they do require good craftsmanship to fit well. Flaps add nicely to the model’s flight characteristics and scale appearance while causing no bad effects. Only slight trim correction is needed when they are used with the recommended throws. They are a highly recommended fun option for those who wish to install them..."

    ScaleType: This (oz13388) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.

    ScaleType is formed from the last part of the Wikipedia page address, which here is
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.

User comments

I've searched for several years to find this set of plans for the TP Bonanza V35. Four years ago, I converted mine from nitro to electric and although it flies well, I couldn't determine whether the firewall was preset to account for the appropriate thrust angle. Needless to say, I now realize, after closer inspection of the drawings, that the firewall is indeed, preset. This equates to my having too much right & down to account for P-factor and particularly, climbing tendencies.
Thanks for posting these plans!!!!

* Credit field

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.
