Default Heat Strip heater

Hi,
I am going to make my own home made nitro buggy engine heater similar to competition heat. What should the wattage of the heat strip be? What is the outside cap of the competition heat made of , the one being put around the heat strip , So i can make a home made one. what should the dimensions of the heatstrip be for .21 buggy engine.

Thankyou

I've seen several people try the "homemade approach"......Honestly, by the time you're all done, you will likely have spent almost what a used heater on RCTech is selling for.

If you can't afford, or don't want to pay for a new one, It might be best to just get one from someone selling on here.

I can't buy used ones from here because I am from Europe and shipping and taxes will be high. The heat strip will only cost me about $20, the only thing I don't know how t do is the outside cover around the heatstrip.

Buy an oven Mit, cut it to fit, put the heat element inside, and sew back together. Inexpensive. As Fae as wattage, but more than you need and use an adjustable resister to dial the heat to what you need.

Have you made one yourself if so can you take any pics and tell me the size of the heats trip I thought 1.5" by 6.5". I think Ill be using a 50 watt heat strip just as the competition heat uses, and I won't fit any resistors, the comp heat gets temperature up very good. What did you do to cover up the top of the engine the part where the igniter is sticked in?

I have only sketched out and created the bill of materials. My plan is a complete cover over the cylinder head....going to require a flat pattern for the fabric, which I can do. Planning on a 50 watt silicone encased heating element. Debating on 1 or 2 inches wide.

I like these little projects, otherwise I would buy the comp heater as they are nice products.

Mine is made of a resistance wire (with isolation). in a multiple Z-shape the wire is layed on a piece of aluminium tape and sewed in some heat resistance fabric. It is finished with some velcro.

What are the dimensions of your heat strip and what is its power and voltage? From where did you buy the heat fabric?to make the cover all i need is fabric and some velcro? What is the temperature you get after 10 minutes of heating with it?

This is made by a clubmember who is making tire heaters for 1/5 cars. This version runs on 12v and takes about 2A so the total resistance of the wire is about 6 ohms. In 10 minutes out of the wind and normal outside temperatures the engine is about 50 degrees C and will be 60 max. Normally this thing is used for heating up a differential from a 1/5 scale car.

He is also producing another one running on 12v / 3 Amp and is closing up the engine more. That can heat the engine up to 70~80 degrees C

According to my physics knowledge the one you have runs on 24w and the new one runs on 36W . Power = current x voltage.I am going to do the oven mitt thing, do I just stick the element into the mitt or I put something on the mitt ex. foil tape or I don't know what and then put the element on it?

You can also think of a small lightbulb, last month I modified a Capricorn tire applicator with some lightbulbs and with a 35 watt G4 lightbulb I reached 100 degrees C on the tires.

What type of heating element are you going to use? Bare with, silicone heat strip, etc.

I am going to buy a 1.5" by 6.5" heat strip 50W and then buy a lipo bag and cut it to form the type of cover I need and then I put some insulation on it and then I stick the heat strip on the insulator and thats it.
